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

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.

Why disabled? How to enable?

We are in process of migrating collectors from python to go.

Configurations are incompatible. All rewritten in go modules are disabled by default. This is a temporary solution, we are working on it.

To enable module please do the following:

• explicitly disable python module in python.d.conf
• explicitly enable go module in go.d.conf
• move python module jobs to go module configuration file (change syntax, see go module configuration file for details).
• restart netdata.service

If case of problems:

• check error.log for module related errors (grep <module name> error.log)
• run plugin in debug mode

Configuration

go.d.plugin itself can be configured using the configuration file /etc/netdata/go.d.conf (to edit it on your system run /etc/netdata/edit-config go.d.conf). This file is a BASH script.

Configurations are written in YAML.

• plugin configuration
• specific module configuration

How to debug a go module

Plugin CLI:

Usage:
  go.d.plugin [OPTIONS] [update every]

Application Options:
  -d, --debug    debug mode
  -m, --modules= modules name (default: all)
  -c, --config=  config dir

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

Specific module debug:

# 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.
