Supervisord collector
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.
Metric | Scope | Dimensions | Units |
---|---|---|---|
summary_processes | global | running, non-running | processes |
processes | process group | running, non-running | processes |
process_state_code | process group | a dimension per process | code |
process_exit_status | process group | a dimension per process | exit status |
process_uptime | process group | a dimension per process | seconds |
process_downtime | process group | a dimension per process | seconds |
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, opennetdata.conf
and look for theplugins
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
