go.d.plugin

go.d.plugin is a Netdata external plugin:

• Independent Operation: Runs as a separate process from Netdata core, visible in system process lists (ps fax).
• Automated Management: Integrated with Netdata's lifecycle management, managed automatically by Netdata (start/stop operations).
• Efficient Communication: Uses a unidirectional pipe for optimal data transfer to Netdata.
• Modular Architecture:
  • Supports an unlimited number of data collection modules.
  • Each module can run multiple collection jobs simultaneously.
  • Easy to extend with new collection modules

Required Linux capabilities

All capabilities are set automatically during Netdata installation using the official installation method.

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

Enable a collector

To enable a collector you should edit go.d.conf to uncomment the collector in question and change it from no to yes.

For example, to enable the example plugin you would need to update go.d.conf from something like:

modules:
#  example: no 

to

modules:
  example: yes

Then restart netdata for the change to take effect.

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

Debugging a Specific Module

To debug a particular module, first switch to the Netdata user:

sudo su -s /bin/bash netdata

Then run the plugin in debug mode, specifying your target module:

# For standard installations
/usr/libexec/netdata/plugins.d/go.d.plugin -d -m <module_name>

# For static installations (e.g., in /opt)
/opt/netdata/usr/libexec/netdata/plugins.d/go.d.plugin -d -m <module_name>

Replace <module_name> with the specific module you wish to debug.
