go.d.plugin
go.d.plugin
is a Netdata
external plugin. It is an orchestrator for data collection modules written in go
.
- It runs as an independent process
ps fax
shows it.
- It is started and stopped automatically by
Netdata
.
- It communicates with
Netdata
via a unidirectional pipe (sending data to the Netdata
daemon).
- Supports any number of data collection modules.
- 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.

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 init.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.
