go.d.plugin

go.d.plugin

go.d.plugin is a Netdata external plugin. It is an orchestrator for data collection modules written in go.

1. It runs as an independent process ps fax shows it.
2. It is started and stopped automatically by Netdata.
3. It communicates with Netdata via a unidirectional pipe (sending data to the Netdata daemon).
4. Supports any number of data collection modules.
5. Allows each module to have any number of data collection jobs.

Install

Go.d.plugin is shipped with Netdata.

Available modules

Configuration

Edit the go.d.conf configuration file using edit-config from the Netdata config directory, which is typically at /etc/netdata.

cd /etc/netdata # Replace this path with your Netdata config directory
sudo ./edit-config go.d.conf

Configurations are written in YAML.

• plugin configuration
• specific module configuration

How to develop a collector

• Take a look at our contributing guidelines.
• Read the How to develop a collector in Go guide.
• Fork this repository to your personal GitHub account.
• Clone locally the forked repository (e.g git clone https://github.com/odyslam/go.d.plugin).
• Using a terminal, cd into the directory (e.g cd go.d.plugin)
• Add your module to the modules directory.
• Import the module in the main.go.
• To build it, run make from the plugin root dir. This will create a new go.d.plugin binary that includes your newly developed collector. It will be placed into the bin directory (e.g go.d.plugin/bin)
• Run it in the debug mode bin/godplugin -d -m <MODULE_NAME>. This will output the STDOUT of the collector, the same output that is sent to the Netdata Agent and is transformed into charts. You can read more about this collector API in our documentation.
• If you want to test the collector with the actual Netdata Agent, you need to replace the go.d.plugin binary that exists in the Netdata Agent installation directory with the one you just compiled. Once you restart the Netdata Agent, it will detect and run it, creating all the charts. It is advised not to remove the default go.d.plugin binary, but simply rename it to go.d.plugin.old so that the Agent doesn't run it, but you can easily rename it back once you are done.
• Run make clean when you are done with testing.

Troubleshooting

Plugin CLI:

Usage:
  orchestrator [OPTIONS] [update every]

Application Options:
  -m, --modules=    module name to run (default: all)
  -c, --config-dir= config dir to read
  -w, --watch-path= config path to watch
  -d, --debug       debug mode
  -v, --version     display the version and exit

Help Options:
  -h, --help        Show this help message

To debug specific module:

# become user netdata
sudo su -s /bin/bash netdata

# run plugin in debug mode
./go.d.plugin -d -m <module name>

Change <module name> to the module name you want to debug. See the whole list of available modules.
