2. It is started and stopped automatically by Netdata.

5. Allows each module to have any number of data collection jobs.

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

Developing

• Add your module to the modules dir.
• Import the module in the main.go.
• To build it execute make from the plugin root dir or hack/go-build.sh.
• Run it in the debug mode bin/godplugin -d -m <MODULE_NAME>.
• Use 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.
