Supervisord monitoring with Netdata
Supervisor is a client/server system that allows its users to monitor and control a number of
processes on UNIX-like operating systems.
This module monitors one or more Supervisor instances, depending on your configuration.
It can collect metrics from
both unix socket
and internal http server
Used methods:
Metrics
All metrics have "supervisord." prefix.

Configuration
Edit the go.d/supervisord.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/supervisord.conf
Endpoints can be both local or remote as long as they expose their metrics on the provided URL.
Here is an example with two endpoints:
jobs:
# via [unix_http_server]
- name: local
url: 'unix:///run/supervisor.sock'
# via [inet_http_server]
- name: local
url: 'http://127.0.0.1:9001/RPC2'
For all available options, see the supervisord
collector's configuration file.
Troubleshooting
To troubleshoot issues with the supervisord
collector, run the go.d.plugin
with the debug option enabled. The output
should give you clues as to why the collector isn't working.
-
Navigate to the plugins.d
directory, usually at /usr/libexec/netdata/plugins.d/
. If that's not the case on
your system, open netdata.conf
and look for the plugins
setting under [directories]
.
cd /usr/libexec/netdata/plugins.d/
-
Switch to the netdata
user.
sudo -u netdata -s
-
Run the go.d.plugin
to debug the collector:
./go.d.plugin -d -m supervisord
