Build Status

Telegraf is an agent for collecting, processing, aggregating, and writing metrics.

Design goals are to have a minimal memory footprint with a plugin system so that developers in the community can easily add support for collecting metrics.

Telegraf is plugin-driven and has the concept of 4 distinct plugin types:

  1. Input Plugins collect metrics from the system, services, or 3rd party APIs
  2. Processor Plugins transform, decorate, and/or filter metrics
  3. Aggregator Plugins create aggregate metrics (e.g. mean, min, max, quantiles, etc.)
  4. Output Plugins write metrics to various destinations

This repository is a fork of Telegraf adding a DDS input plugin (dds_consumer). It is synced up with the Telegraf v1.14 branch.

Minimum Requirements

Telegraf shares the same minimum requirements as Go:

  • Linux kernel version 2.6.23 or later
  • Windows 7 or later
  • FreeBSD 11.2 or later
  • MacOS 10.11 El Capitan or later

Nightly Builds

How to use it:

Add RTI Connector C library to the library path

RTI Go Connector dynamically links to RTI Connector C library. The path for Connector C library should be included in the environment variable for library path (e.g. LD_LIBRARY_PATH). After you build Telegraf, the RTI C Connector library is checked out under the vendor directory. You can include the path like the following.

$ cd ~/src
$ git clone https://github.com/rticommunity/rticonnextdds-connector-go.git
$ export LD_LIBRARY_PATH=~/src/rticonnextdds-connector-go/rticonnextdds-connector/lib/linux-x64:$LD_LIBRARY_PATH

See usage with:

./telegraf --help

Generate a telegraf config file:

./telegraf config > telegraf.conf

Run a single telegraf collection, outputing metrics to stdout:

./telegraf --config telegraf.conf --test
telegraf --section-filter agent:inputs:outputs --input-filter cpu --output-filter influxdb config

Generate config with DDS input & influxdb output plugins defined:

./telegraf --input-filter dds_consumer --output-filter influxdb config

Generate a config file with DDS input & file output plugins:

./telegraf --input-filter dds_consumer --output-filter file config > dds_to_file.conf

When you run with dds_consumer plugin, please make sure an XML file for DDS configurations is located at the config_path in your Telegraf TOML config.

Example XML files (e.g. ShapeExample.xml) and Telegraf config files are given under example_configs directory.

./telegraf --config ./example_configs/dds_to_file.conf

Telegraf with the example config will create a DDS DataReader with a "Square" topic. They are all defined in ShapeExample.xml. You can simply test with the RTI Shapes Demo with publishing data with "Square" topic.
