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.

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

modules:
  example: yes

Then restart netdata for the change to take effect.

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
