newrelic-alerts-manager

newrelic-alerts-manager is a simple utility which allows to dynamically update the newrelic server alerting policies based on the value of some specific tags added to them.

The code is compatible with Python 3

Documentation of the APIs used:

#INSTALLATION

Example

Install via pip: pip install newrelic-alerts-manager

Upload to PyPI

  1. Create a .pypirc configuration file. This file holds your information for authenticating with PyPI.

    [distutils]
    index-servers = pypi
    
    [pypi]
    repository=https://pypi.python.org/pypi
    username=your_username
    password=your_password
    
  2. Login and upload it to PyPI

    python setup.py register -r pypi
    python setup.py sdist upload -r pypi
    

#USAGE

##ALERT_CONFIG configuration

#####example configuration:


alert_policies:
  - name: "Alert Policy LIVE"
    tags:
    - live-web
    - live-backend
  - name: "Alert Policy DEV"
    tags:
    - dev-web
    - dev-database

the ALERT_CONFIG configuration is a yaml formatted document, containing an array of alert_policies. Each alert policy is identified by its newrelic name and contains a list of server tags (newrelic labels) listing the servers associated with it (with all its conditions).

The only supported server label is currently Deployment. Therefore ie., according to the configuration above, the only servers associated with the Alert Policy LIVE would be those labelled in newrelic with one or both of the Deployment:live-web and Deployment:live-backend server labels.

##Running as a web app

##Running on Cloudfoundry

When running on Cloudfoundry you will need a properly formatted application manifest. One example manifest can be found below, as well as in the manifest-example.yml file:

applications:
- name: newrelic-alerts-manager
  memory: 128M
  instances: 1
  env:
    NEWRELIC_API_KEY: <your_secret_new_relic_key>
    ALERT_CONFIG: |
      ---
      alert_policies:
          - name: "Alert Policy LIVE"
            tags:
            - live-web
            - live-backend
          - name: "Alert Policy DEV"
            tags:
            - dev-web
            - dev-database

in this case the alert configuration is passed to the app in the form of an online yaml document.

The NEWRELIC_API_KEY variable can be either specified in the manifest itself or binding your app to a newrelic service, created via a service broker ie. using newrelic-cf.

In this case the key is expected to be found under the VCAP_SERVICES["newrelic"][0]["credentials"]["licenseKey"] dictionary key.

##Running as a script

An alert config file named alert_config.yml should be present in the execution directory. An example can be found at the root of this project in the alert_config.example.yml file.

You can specify an alternative configuration file path via the -c flag

You can run the utility by executing the run script:

./run -k <new_relic_api_key>

or after installing the pip package

python setup.py install

by running

newrelic-alerts-manager -k <new_relic_api_key>
