reload config plugin go.d/ping without restart service netdata

[cayenne17]

Hello,
I would like to know if there is a way of adding a go.d/ping host and reloading the configuration without restarting netdata and without having any interruption in the graphics?

Hey, @cayenne17. You can reload go.d.plugin by sending SIGHUP to its process PID. You will get small gaps only on go.d.plugin charts.

Alternatively, you can try using the file-watching feature (go.d.plugin rereads it on every change and adds/stops jobs automatically) - but it is not documented and could break in the future. But if you want:

• create a file anywhere and make sure it is readable by netdata user.
• add -w PATH_TO_THE_FILE to go.d.plugin command options in netdata.conf.
• ...
• profit!

Example:

• create /opt/netdata/etc/netdata/ping.conf (could be /etc/netdata/ping.conf in your case, depends on the install prefix)

jobs:
  - name: first
    hosts:
      - 8.8.8.8

• make go.d.plugin to watch it

# netdata.conf
[plugin:go.d]
        # update every = 1
        command options = -w /opt/netdata/etc/netdata/ping.conf

• restart netdata service

After that, you can add/remove jobs in /opt/netdata/etc/netdata/ping.conf, go.d.plugin will pick up the changes automatically.

@cayenne17 Also we are working on a feature that will allow you to do the same (add/remove jobs, check their status, etc.) using UI.
