AppSignal for Elixir changelog

2.13.2

Published on 2024-11-07.

Fixed

Fix an issue where the extension fails to build on ARM64 Linux. (patch c350f4cc)

2.13.1

Published on 2024-11-06.

Added

Add reported_by tag to errors reported by the legacy error backend. This makes it easier to understand whether an error is being reported by the error backend. (patch 440e53dd)
Set the app revision config option for Scalingo deploys automatically. If the CONTAINER_VERSION system environment variable is present, it will use used to set the revision config option automatically. Overwrite it's value by configuring the revision config option for your application. (patch dc86ad85)

Changed

Change the primary download mirror for integrations. (patch f3d201c1)

Fixed

Fix parentheses warning for Tesla on Elixir 1.17.x. (patch 6a62ea1a)
Fix an issue where, after a certain amount of time, check-ins would no longer be sent.

This issue also caused the default Hackney connection pool to be saturated, affecting other code that uses the default Hackney connection pool.

(patch 7233adfa)

2.13.0

Published on 2024-09-26.

Added

Add support for heartbeat check-ins.

Use the Appsignal.CheckIn.heartbeat method to send a single heartbeat check-in event from your application. This can be used, for example, in a GenServer's callback:
```
@impl true
def handle_cast({:process_job, job}, jobs) do
  Appsignal.CheckIn.heartbeat("job_processor")
  {:noreply, [job | jobs], {:continue, :process_job}}
end
```
Heartbeats are deduplicated and sent asynchronously, without blocking the current thread. Regardless of how often the .heartbeat method is called, at most one heartbeat with the same identifier will be sent every ten seconds.

Pass continuous: true as the second argument to send heartbeats continuously during the entire lifetime of the current process. This can be used, for example, during a GenServer's initialisation:
```
@impl true
def init(_arg) do
  Appsignal.CheckIn.heartbeat("my_genserver", continuous: true)
  {:ok, nil}
end
```
You can also use Appsignal.CheckIn.Heartbeat as a supervisor's child process, in order for heartbeats to be sent continuously during the lifetime of the supervisor. This can be used, for example, during an Application's start:
```
@impl true
def start(_type, _args) do
  Supervisor.start_link([
    {Appsignal.CheckIn.Heartbeat, "my_application"}
  ], strategy: :one_for_one, name: MyApplication.Supervisor)
end
```
(minor 7b2ff327)

Changed

Send check-ins concurrently. When calling Appsignal.CheckIn.cron, instead of blocking the current process while the check-in events are sent, schedule them to be sent in a separate process. (patch e7cead98)

2.12.3

Published on 2024-08-26.

Fixed

Make Appsignal.Ecto.Repo's default_options/1 function overridable. If your Ecto repo uses Appsignal.Ecto.Repo and implements its own default_options/1, it must call super to merge its default options with those of Appsignal.Ecto.Repo:
```
defmodule MyEctoRepo
  use Appsignal.Ecto.Repo

  def default_options(operation) do
    super(operation) ++ [
      # ... your default options here ...
    ]
  end
end
```
(patch 3d9634c7)
Fix an issue where Ecto transactions in parallel preloads would not be instrumented correctly when using Appsignal.Ecto.Repo, causing the query in the Ecto transaction to not be instrumented and the sample to be incorrectly closed as an earlier time. (patch d5e132e0)

2.12.2

Published on 2024-08-14.

Changed

Rename heartbeats to cron check-ins. Calls to Appsignal.heartbeat and Appsignal.Heartbeat should be replaced with calls to Appsignal.CheckIn.cron and Appsignal.CheckIn.Cron, for example:
```
# Before
Appsignal.heartbeat("do_something", fn ->
  do_something()
end)

# After
Appsignal.CheckIn.cron("do_something", fn ->
  do_something
end)
```
(patch 1c3b9c67)

Deprecated

Calls to Appsignal.heartbeat and to methods in Appsignal.Heartbeat will emit a deprecation warning at compile-time. (patch 1c3b9c67)

2.12.1

Published on 2024-06-25.

Fixed

990f3b26 patch - When running the installation script on Microsoft Windows, some components threw an error. AppSignal doesn't support Windows, so the installation script won't run on Windows anymore. Preventing errors from raising.

2.12.0

Published on 2024-06-05.

Changed

6ce84310 minor - Group GraphQL queries by operation names if available. It will no longer group all errors and performance measurements under the same action name. If no operation name is set, it will use the default action name of the HTTP request route, like POST /graphql.

If you do not wish to use the operation name, or customize the action name for the GraphQL query request, use the Appsignal.Span.set_name in a plug middleware that is called before or after the HTTP request is made:
```
Appsignal.Span.set_name(Appsignal.Tracer.root_span(), "MyActionName")
```

2.11.0

Published on 2024-06-04.

Added

4508bd10 patch - Add Appsignal.Span.set_name_if_nil helper. This helper can be used to not overwrite previously set span names, and only set the span name if it wasn't set previously. This will used most commonly in AppSignal created integrations with other libraries to allow apps to set custom span names.

Changed

cb7c2e9d minor - Turn error backend off by default. This will prevent errors from being reported without much context. If you're missing errors after this change, set the enable_error_backend config option to true, and let us know what errors you're missing at support@appsignal.com.
4b8bbf75 patch - Add debug and error logs to probes to better track what it's doing. This is helpful when debugging issues with the minutely probes system.

2.10.2

Published on 2024-05-14.

Added

1a87c94a patch - Support Kamal-based deployments. Read the KAMAL_VERSION environment variable, which Kamal exposes within the deployed container, if present, and use it as the application revision if it is not set. This will automatically report deploy markers for applications using Kamal.

Changed

a19671f6 patch - Log debug messages when metrics are received for easier debugging.

2.10.1

Published on 2024-04-25.

Fixed

5a7810c8 patch - Fix the Phoenix filter_parameters config option support for partial key matches. When configuring config :phoenix, filter_parameters with ["key"] or {:discard, ["key"]}, it now also matches partial keys like "my_key", just like Phoenix's logger does.

2.10.0

Published on 2024-04-22.

Added

840e6c0b minor - Heartbeats are currently only available to beta testers. If you are interested in trying it out, send an email to support@appsignal.com!

Add heartbeats support. You can send heartbeats directly from your code, to track the execution of certain processes:
```
def send_invoices do
  # ... your code here ...
  Appsignal.heartbeat("send_invoices")
end
```
You can pass a function to Appsignal.heartbeat, to report to AppSignal both when the process starts, and when it finishes, allowing you to see the duration of the process:
```
def send_invoices do
  Appsignal.heartbeat("send_invoices", fn ->
    # ... your code here ...
  end)
end
```
If an exception is thrown within the function, the finish event will not be reported to AppSignal, triggering a notification about the missing heartbeat. The exception will bubble outside of the heartbeat function.
d56d3ebd patch - Implement the ignore_logs configuration option, which can also be configured as the APPSIGNAL_IGNORE_LOGS environment variable.

The value of ignore_logs is a list (comma-separated, when using the environment variable) of log line messages that should be ignored. For example, the value "start" will cause any message containing the word "start" to be ignored. Any log line message containing a value in ignore_logs will not be reported to AppSignal.

The values can use a small subset of regular expression syntax (specifically, ^, $ and .*) to narrow or expand the scope of lines that should be matched.

For example, the value "^start$" can be used to ignore any message that is exactly the word "start", but not messages that merely contain it, like "Process failed to start". The value "Task .* succeeded" can be used to ignore messages about task success regardless of the specific task name.

Fixed

38511da4 patch - Remove broken link about 1.x upgrade

2.9.2

Published on 2024-03-22.

Fixed

4567ce04 patch - Drop non-500 Plug errors in add_error/3

2.9.1

Published on 2024-03-20.

Added

c833c8a4 patch - Implement CPU count configuration option. Use it to override the auto-detected, cgroups-provided number of CPUs that is used to calculate CPU usage percentages.

To set it, use the cpu_count configuration option, or the APPSIGNAL_CPU_COUNT environment variable.

2.9.0

Published on 2024-03-06.

Added

be785ea9 patch - Add histogram support to the OpenTelemetry HTTP server. This allows OpenTelemetry-based instrumentations to report histogram data to AppSignal as distribution metrics.

Changed

2d3130fd minor - Breaking change: Normalize CPU metrics for cgroups v1 systems. When we can detect how many CPUs are configured in the container's limits, we will normalize the CPU percentages to a maximum of 100%. This is a breaking change. Triggers for CPU percentages that are configured for a CPU percentage higher than 100% will no longer trigger after this update. Please configure triggers to a percentage with a maximum of 100% CPU percentage.
1566a4a8 patch - Update the Mix config import in the config/appsignal.exs file to use import Config, rather than the deprecated use Mix.Config.
2d3130fd patch - Support fractional CPUs for cgroups v2 metrics. Previously a CPU count of 0.5 would be interpreted as 1 CPU. Now it will be correctly seen as half a CPU and calculate CPU percentages accordingly.
fb7568ac patch - Update bundled trusted root certificates.

Fixed

ad0fdb0c patch - Fix (sub)traces not being reported in their entirety when the OpenTelemetry exporter sends one trace in multiple export requests. This would be an issue for long running traces, that are exported in several requests.

2.8.3

Published on 2024-02-01.

Added

e685b22f patch - Set data on spans with the custom_on_create_fun hook. This hook is called upon the creation of every span. This can be useful to add tags to internal traces and otherwise difficult to access traces.

This won't be necessary for most scenarios. We recommend following our tagging guide instead.
```
defmodule MyApp.Appsignal do
  def custom_on_create_fun(_span) do
    Appsignal.Span.set_sample_data(Appsignal.Tracer.root_span, "tags", %{"locale": "en"})
  end
end
```
```
# config/config.exs
config :appsignal, custom_on_create_fun: &MyApp.Appsignal.custom_on_create_fun/1
```

Changed

924a3ffa patch - Make the debug log message for OpenTelemetry spans from libraries we don't automatically recognize more clear. Mention the span id and the instrumentation library.
924a3ffa patch - Fix an issue where queries containing a MySQL leading type indicator would only be partially sanitised.

2.8.2

Added

47f4a8df patch - Add Appsignal.Ecto.Repo to support parallel preloads.

For AppSignal to be able to instrument parallel preloads, the current instrumentation context needs to be passed from the Elixir process that spawns the preload to the short-lived processes that run each of the parallel queries.

By replacing use Ecto.Repo with use Appsignal.Ecto.Repo, the appropriate telemetry context will be passed so that AppSignal can correctly instrument these queries:
```
defmodule MyApp.Repo do
  # replace `use Ecto.Repo` with `use Appsignal.Ecto.Repo`
  use Appsignal.Ecto.Repo,
    otp_app: :my_app,
    adapter: Ecto.Adapters.Postgres
end
```

2.8.1

Changed

40dc85ef patch - Fix disk usage returning a Vec with no entries on Alpine Linux when the df --local command fails.
92d948fa patch - Add support for lists in the sample data as root values on spans, as shown below. Previously we only supported lists as nested objects in maps.
```
Appsignal.Span.set_sample_data(
  Appsignal.Tracer.root_span,
  "custom_data",
  [
    "value 1",
    "value 2"
  ]
)
```

Removed

40dc85ef patch - Remove the appsignal_set_host_gauge and appsignal_set_process_gauge extension functions. These functions were already deprecated and did not report any metrics.

Fixed

9ec351a7 patch - Fix missing error metrics for the error rate and error count graphs in some scenarios, like with Node.js Koa apps.

a339fc1d patch - Add support for keywords lists in sample data on spans. These would previously be shown an empty list.

Appsignal.Span.set_sample_data(
  Appsignal.Tracer.root_span,
  "custom_data",
  %{"keyword_list": [foo: "some value", "bar": "other value"]}
)

2.8.0

Changed

8e8911f0 minor - Always use Jason to encode JSON. This removes the need to install either Jason or Poison alongside AppSignal, simplifying our installation instructions.
9dbf8d82 patch - Filter more disk mountpoints for disk usage and disk IO stats. This helps reduce noise in the host metrics by focussing on more important mountpoints.

The following mountpoint are ignored. Any mountpoint containing:
- /etc/hostname
- /etc/hosts
- /etc/resolv.conf
- /snap/
- /proc/

Fixed

9dbf8d82 patch - - Support disk usage reporting (using df) on Alpine Linux. This host metric would report an error on Alpine Linux.
- When a disk mountpoint has no inodes usage percentage, skip the mountpoint, and report the inodes information successfully for the inodes that do have an inodes usage percentage.

2.7.13

Changed

c883847a patch - Bump agent to eec7f7b

Updated the probes dependency to 0.5.2. CPU usage is now normalized to the number of CPUs available to the container. This means that a container with 2 CPUs will have its CPU usage reported as 50% when using 1 CPU instead of 100%. This is a breaking change for anyone using the cpu probe.

If you have CPU triggers set up based on the old behaviour, you might need to update those to these new normalized values to get the same behaviour. Note that this is needed only if the AppSignal integration package you're using includes this change.

2.7.12

Changed

33f08759 patch - Improve Ecto transaction instrumentation. Queries performed as part of an Ecto.Multi or an Ecto.Repo.transaction were already individually instrumented, but now they are displayed in the event timeline as child events of a broader transaction event. An additional event is added at the end of the transaction, to denote whether the transaction was committed or rolled back.

2.7.11

Changed

dae88280 patch - Bump agent to b604345.
- Add an exponential backoff to the retry sleep time to bind to the StatsD, NGINX and OpenTelemetry exporter ports. This gives the agent a longer time to connect to the ports if they become available within a 4 minute window.
- Changes to the agent logger:
  - Logs from the agent and extension now use a more consistent format in logs for spans and transactions.
  - Logs that are for more internal use are moved to the trace log level and logs that are useful for debugging most support issues are moved to the debug log level. It should not be necessary to use log level 'trace' as often anymore. The 'debug' log level should be enough.
- Add running_in_container to agent diagnose report, to be used primarily by the Python package as a way to detect if an app's host is a container or not.
e6c4c79f patch - Bump agent to 1dd2a18.
- When adding an SQL body attribute via the extension, instead of truncating the body first and sanitising it later, sanitise it first and truncate it later. This prevents an issue where queries containing very big values result in truncated sanitisations.

Fixed

197e3610 patch - Avoid reporting an Oban insert job event as a new incident. This should fix an issue where "insert job" events with little information show up in AppSignal as their own incidents when Oban jobs are inserted from an uninstrumented context that has no parent spans.

2.7.10

Added

68ec699e patch - Implement an Erlang :logger handler for sending logs from AppSignal, in preparation for the eventual deprecation of Elixir logger backends.

Add a convenience method to configure this logger handler automatically, with the right settings for AppSignal:
```
Appsignal.Logger.Handler.add("my_app", :plaintext)
```
To remove the logging handler, call the .remove method:
```
Appsignal.Logger.Handler.remove()
```

Changed

cc526cb6 patch - Bump agent to e8207c1.
- Add memory_in_percentages and swap_in_percentages host metrics that represents metrics in percentages.
- Ignore /snap/ disk mountpoints.
- Fix issue with the open span count in logs being logged as a negative number.
- Fix agent's TCP server getting stuck when two requests are made within the same fraction of a second.

Fixed

bcbc1c6a patch - Fix configuration options set with atoms. The options log and log_level can now be set as an Atom, and we'll cast them to a string internally to avoid any ArgumentError from the Nif.
92a7e886 patch - Fix support for warning log_level. Only warn would work, now warning also works as documented.

2.7.9

Fixed

ebd39c39 patch - Bump agent to 6133900.
- Fix disk_inode_usage metric name format to not be interpreted as a JSON object.

2.7.8

Added

489615ae patch - Add the host_role config option. This config option can be set per host to generate some metrics automatically per host and possibly do things like grouping in the future.

Changed

7b3875b2 patch - Bump agent to 6bec691.
- Upgrade sql_lexer to v0.9.5. It adds sanitization support for the THEN and ELSE logical operators.
7781f405 patch - Bump agent to version d789895.
- Increase short data truncation from 2000 to 10000 characters.

2.7.7

Added

75e70db2 patch - Use RENDER_GIT_COMMIT environment variable as revision if no revision is specified.
7c3103ae patch - Allow JSON and Logfmt log messages
2b3eab1d patch - Allow configuration of the agent's TCP and UDP servers using the bind_address config option. This is by default set to 127.0.0.1, which only makes it accessible from the same host. If you want it to be accessible from other machines, use 0.0.0.0 or a specific IP address.
08aedeef patch - Report total CPU usage host metric for VMs. This change adds another state tag value on the cpu metric called total_usage, which reports the VM's total CPU usage in percentages.

Changed

ece48144 patch - Bump agent to 32590eb.
- Only ignore disk metrics that start with "loop", not all mounted disks that end with a number to report metrics for more disks.

Fixed

b7089a8e patch - Handle atoms for categories in transaction_event decorator

2.7.6

Added

be411435 patch - Add set_sample_data_if_nil function to Appsignal.Span, allowing for parameters to be set only if they would not override other parameters.
be411435 patch - Use RENDER_GIT_COMMIT environment variable as revision if no revision is specified.

2.7.5

Changed

5e5918f5 patch - Improve argument cleaning.

The output should appear in a more familiar format for Elixir developers. Potentially personally identifiable data is removed and the output is truncated to make it easier to understand, while attempting to provide enough information to differentiate between different function clauses.

Fixed

af402113 patch - Improve Tracer performance by removing duplicate runtime configuration and storage checks

2.7.4

Fixed

dcdac33e patch - Add handling for cowboy error edge cases to prevent error backend crashes

2.7.3

Added

37810e11 patch - Allow configuration of the agent's StatsD server port through the statsd_port option.
0caf8330 patch - Add automatic instrumentation for Tesla.

Changed

7e7c097d patch - Bump agent to fd8ee9e.
- Rely on APPSIGNAL_RUNNING_IN_CONTAINER config option value before other environment factors to determine if the app is running in a container.
- Fix container detection for hosts running Docker itself.
- Add APPSIGNAL_STATSD_PORT config option.

2.7.2

Changed

49467767 patch - Update agent to v-f9b0c15
- Add more span API logging.

2.7.1

Changed

2d424448 patch - Bump agent to 8d042e2.
- Support multiple log formats.
a886a2b7 patch - Bump agent to dee4fcb.
- Support cgroups v2. Used by newer Docker engines to report host metrics. Upgrade if you receive no host metrics for Docker containers.
- Remove trailing comments in SQL queries, ensuring queries are grouped consistently.

Added

63adf596 patch - Add NGINX metrics support. See our documentation for details.

2.5.1

Added

837e0285 patch - Add config options to disable automatic Ecto, Finch and Oban instrumentations. Set instrument_ecto, instrument_finch or instrument_oban to false in order to disable that instrumentation.
b3a77a73 patch - Add a report_oban_errors config option to decide when to report Oban errors. When set to "all", all errors will be reported; when set to "none", no errors will be reported. Set it to "discard" to only report errors when the job is discarded due to the error and won't be re-attempted.
e52997c8 patch - Add metadata functions for Plug/Phoenix apps

Fixed

837e0285 patch - Fix the default value of enable_error_backend so it defaults to true when the config option is not set.

2.5.0

Added

bc14f302 minor - Add Oban instrumentation. Jobs processed by your Oban workers will now be instrumented with AppSignal, and job insertions will appear as events in your performance samples' event timelines.
65107c60 patch - Track the Operating System release/distro in the diagnose report. This helps us with debugging what exact version of Linux an app is running on, for example.

2.4.3

Fixed

1b69bf4e patch - Fix an issue where user configuration enabling metrics for Hackney would cause the AppSignal Agent installation to fail.

2.4.2

Fixed

a5c810d4 patch - Fix an issue where reporting an exception for a function call whose arguments contain a map of PID would raise a second exception instead.

2.4.1

Changed

4473ffee patch - Add enable_error_backend configuration option

2.4.0

Added

beb0c43b minor - Support log collection from Elixir apps using the new AppSignal Logging feature. Learn more about AppSignal's Logging on our docs.

Changed

b2dddb11 patch - Replace arguments in stack traces with sanitized versions instead of stripping them out completely

2.3.1

Fixed

5a9b4b6c patch - Fix FunctionClauseError for old Finch versions. This change explicitly ignores events from old Finch versions, meaning only Finch versions 0.12 and above will be instrumented, but using Finch versions 0.11 and below won't cause an event handler crash.

2.3.0

Added

2aaf55be minor - Add Finch integration. HTTP requests performed with Finch will show up as events in the sample view.

2.2.19

Fixed

be7825e1 patch - Fix extension linking on Alpine Linux ARM64 systems.

2.2.18

Fixed

05f59d31 patch - Fix compile-time error about symbol names starting with a comma. Updated the linking script to not include the comma.

2.2.17

Fixed

b600e85a patch - Fix compile-time warning about an unused funtion in the extension. The _set_span_attribute_sql_string function wasn't hooked up, which didn't produce any issues since the SQL queries coming from Ecto don't need to be sanitized any further (sensitive data is already stripped out). This patch still runs them through AppSignal's SQL sanitizer to fix the warning and behave as promised, theoretically.
910ad1dd patch - Fix compile-time error that broke linking on macOS 12.6, more specifically the latest Xcode at this time (version 14.0 14A309).

2.2.16

Changed

03b8306a patch - Bump agent to 06391fb
- Accept "warning" value for the log_level config option.
- Add aarch64 Linux musl build.
- Improve debug logging from the extension.
- Fix high CPU issue for appsignal-agent when nothing could be read from the socket.

Fixed

4d72d791 patch - Always return :ok from Appsignal.config_change/3
914f013b patch - Always return the Span from span setter functions, to allow for chaining setter calls with optional values

2.2.15

Changed

ab876253 patch - Bump agent to v-d573c9b
- Clean up payload storage before sending. Should fix issues with locally queued payloads blocking data from being sent.
- Add OpenTelemetry support for the Span API. Not currently implemented in this package's extension.

Fixed

d66ad2d8 patch - Always return the Span from Span.set_attribute/3, making it easier to chain this function call.

2.2.14

Fixed

ffb3ab29 patch - Fix compile-time error with empty configurations
c3599ae9 patch - Improve the error message on extension load failure. The error message will now print more details about the installed and expected architecture when they mismatch. This is most common on apps mounted on a container after first being installed on the host with a different architecture than the container.
4ac415f1 patch - Don't crash at compile time when AppSignal is not configured

2.2.13

Fixed

26be6e58 patch - Fix session data by reverting the sample data key change

2.2.12

Added

65c5d716 patch - Don't set session data when the send_session_data configuration is set to false

2.2.11

Added

e287e58c patch - Allow ignoring specific pids through Tracer.ignore/1
c325114a patch - Log messages are now sent through a centralised logger, defaulting to logging to the /tmp/appsignal.log file. To log to standard output instead, set the log config property to "stdout".
96c60363 patch - Don't set parameters when the send_params configuration is set to false

Changed

bb6c7a65 patch - Add the config "override" source to better communicate and help debug when certain config options are set. This is used by the diagnose report. The override source is used to set the new config option value when a config option has been renamed, like send_session_data.
003a2edd patch - The extension installation will no longer fail when the CA certificate file is not accessible.
db97b2f6 patch - Bump agent to v-bbc830a
- Support batched statsd messages
- Set start times for spans with traceparents
- Check duration in transactions for negative and too high values
709224ad patch - Bump agent to v-f57e6cb
- Enable process metrics on Heroku and Dokku

2.2.10

Added

0469f4b2 patch - Add send_session_data option to configure if session data is automatically included in spans. By default this is turned on. It can be disabled by configuring send_session_data to false.

Changed

ffe65216 patch - Remove Ruby exclusive headers from request_headers defaults.
c0a98928 patch - Bump AppSignal agent version to 15ee07b. Add internal tracking of transmission duration.
8c14f827 patch - The diagnose library report now reports the agent version from the committed agent file, rather than the downloaded version, which is reported in the installation report.

Deprecated

0469f4b2 patch - Deprecate skip_session_data option in favor of the newly introduced send_session_data option. If it is configured, it will print a warning on AppSignal load, but will also retain its functionality until the config option is fully removed in the next major release.

Fixed

e4ec8e68 patch - Prefer the value of the log_level config option, instead of the deprecated debug config option, when deciding whether to log a debug message. If log_level does not have a value, or its value is invalid, the values of the deprecated debug and transaction_debug_mode config options are taken into account.

2.2.9

Fixed

2b78e1e2 patch - Fix debug and transaction_debug_mode log options. If set, previously the log_level would remain "info", since version 2.2.8.

2.2.8

Added

4a9bcca3 patch - Add "log_level" config option. This new option allows you to select the type of messages AppSignal's logger will log and up. The "debug" option will log all "debug", "info", "warning" and "error" log messages. The default value is: "info"

The allowed values are:
- error
- warning
- info
- debug
10078177 patch - Add send_environment_metadata config option to configure the environment metadata collection. For more information, see our environment metadata docs.
10078177 patch - Add the Erlang scheduler utilization to the metrics reported by the minutely probes. The metric is reported as a percentage value with the name erlang_scheduler_utilization, with the tag type set to "normal" and the tag id set to the ID of the scheduler in the Erlang VM.

Changed

10078177 patch - Bump agent to v-5b63505
- Only filter parameters with the filter_parameters config option.
- Only filter session data with the filter_session_data config option.
10078177 patch - Remove the valid key from the diagnose output. It's not a configuration option that can be configured, but an internal state check if the configuration was considered valid.
10078177 patch - Print the extension installation dependencies and flags in the diagnose report output.
10078177 patch - Standardize diagnose validation failure message. Explain the diagnose request failed and why.
f3bb8546 patch - Bump agent to v-0db01c2
- Add log_level config option in extension.
- Deprecate debug and transaction_debug_mode option in extension.

Deprecated

4a9bcca3 patch - Deprecate "debug" and "transaction_debug_mode" config options in favor of the new "log_level" config option.

Removed

f40ead99 patch - Remove the unused allocation tracking config option.

Fixed

10078177 patch - Fix a bug where setting the :phoenix, :filter_parameters configuration key to an allow-list of the form {:keep, [keys]} would apply this filtering to all sample data maps. The filtering is now only applied to the params sample data map.
10078177 patch - Fix the Push API key validator request query params encoding.
10078177 patch - When the Push API key config option value is an empty string, or a string with only whitespace characters, it is not considered valid anymore.
10078177 patch - Transmit the path file modes in the diagnose report as an octal number. Previously it send values like 33188 and now it transmits 100644, which is a bit more human readable.
10078177 patch - Improve parameter and session data filtering options. Previously all filtering was done with one combined denylist of parameters and session data. Now filter_parameters only applies to parameters, and filter_session_data only applies to session data.
10078177 patch - Fix the download of the agent during installation when Erlang is using an OpenSSL version that does not support TLS 1.3, such as versions below OpenSSL 1.1.1.
ad0b00f1 patch - Suppress a warning emitted by Telemetry 1.0.0, regarding the performance penalty of using local functions as event handlers, by specifying the module of the captured function.

2.2.7

f07f9cf9 patch - Bump agent to 09308fb.
- Update sql_lexer dependency with support for reversed operators in queries.
- Add debug level logging to custom metrics in transaction_debug_mode.
- Add hostname config option to standalone agent.

2.2.6

acb7295 patch - Print String values in the diagnose report surrounded by quotes, and booleans as "true" and "false", rather than "yes" and "no". Makes it more clear that it's a value and not a label we print.
e71792f patch - Fix diagnose output rendering an additional empty line for the appsignal.log file. It appeared that only 9 lines were printed instead of the 10 expected lines.
422cbd1 patch - Render the install report errors in the diagnose CLI output fewer times. A missing download and/or install report could sometimes be displayed up to two times, in total four errors.
f7c0b1e patch - Support mix task diagnose arguments. When an app is released with mix release CLI arguments cannot normally be passed to the diagnose task. Use the eval command pass along the CLI arguments as function arguments.
```
mix format
# Without arguments
bin/your_app eval ':appsignal_tasks.diagnose()'
# With arguments
bin/your_app eval ':appsignal_tasks.diagnose(["--send-report"])'
```
c51c065 patch - Update diagnose output labels to be similar to our other language integrations.
9d3e253 patch - Add new config option to enable/disable StatsD server in the AppSignal agent. This new config option is called enable_statsd and is set to false by default. If set to true, the AppSignal agent will start a StatsD server on port 8125 on the host.

2.2.5

e7d676a9 patch - Update SSL configuration for OTP 23 and newer to fix the Cloudfront mirror download during installation.
7ccf75ce patch - Fix install result message to no longer show a success message when an installation failure occurred.

2.2.4

787684bf patch - Installation report improved for download errors. Download errors are more descriptive in the installation result of the diagnose report.

2.2.3

- Support JSON PostgreSQL operator in sql_lexer.
- Do not strip comments from SQL queries.

2.2.2

c6772da3 patch - Fix extension installer from cached source in /tmp directory. This would cause installation errors of the package if the AppSignal package was reinstalled again on a host that already installed it once.

2.2.1

a7987f3 patch - Add mirrors to download the agent

2.2.0

2.1.12

07d1ea17 patch - Bump agent to c2024bf with appsignal-agent diagnose timing issue fix when reading the report and improved filtering for HTTP request transmission logs.

2.1.8

b2c888dc patch - Update APPSIGNAL_BUILD_FOR_MUSL behavior to only listen to the values 1 and true. This way APPSIGNAL_BUILD_FOR_MUSL=false is not interpreted to install the musl build.
f467daf9 patch - Add Linux ARM 64-bit experimental build, available behind a feature flag. To test this set the APPSIGNAL_BUILD_FOR_LINUX_ARM flag before compiling your apps: export APPSIGNAL_BUILD_FOR_LINUX_ARM=1 <command>. Please be aware this is an experimental build. Please report any issue you may encounter at our support email.
b8075176 patch - Use MapSets for Monitor's internal monitor list. As uniqueness is guaranteed (you can't monitor a particular pid more than once), MapSet is a better data structure to store this information, since all its operations are constant-time instead of linear-time.

Add Phoenix Telemetry event handler to add Phoenix 1.5 instrumentation. PR #528 & #538

Before version Phoenix version 1.5. AppSignal’s Phoenix instrumentation depended on data from the Phoenix instrumenter, and the installation instructions included a step to attach AppSignal’s instrumenter to your application in your app’s configuration:
```
config :appsignal_phoenix_example, AppsignalPhoenixExampleWeb.Endpoint,
  #...
  instrumenters: [Appsignal.Phoenix.Instrumenter]
```
From Phoenix 1.5 on, the old Phoenix instrumentation is deprecated and removed in favor of the new Telemetry-based instrumentation. When upgrading to Phoenix 1.5, you’ll see a warning during compilation when using the old instrumenters:
```
[warn] :instrumenters configuration for
AppsignalPhoenixExampleWeb.Endpoint is deprecated and has no effect
```
To switch to the new instrumentation, make sure you're running version 1.12.0 of the AppSignal integration or higher. Then, remove the instrumenters configuration option from your endpoint configuration. The new instrumentation should appear automatically in your samples as an event named call.phoenix_endpoint.
