Configuring the agent to monitor Supervisor

1. Configure /etc/sd-agent/conf.d/supervisord.yaml

init_config:

instances:
# - name: server0 # Required. An arbitrary name to identify the supervisord server
  • If you need to specify a custom hostname, port, user/password or other fine tuned config, you should configure the rest of the config file as necessary.

2. Restart the agent

sudo /etc/init.d/sd-agent restart

or

sudo systemctl restart sd-agent

Verifying the configuration
Execute info to verify the configuration with the following:

sudo /etc/init.d/sd-agent info 

or

/usr/share/python/sd-agent/agent.py info

If the agent has been configured correctly you'll see an output such as:

supervisor
-----
  - instance #0 [OK]
  - Collected * metrics

You can also view the metrics returned with the following command:

sudo -u sd-agent /usr/share/python/sd-agent/agent.py check supervisord

Configuring graphs

Click the name of your server from the Devices list in your Server Density account then go to the Metrics tab. Click the + Graph button on the right then choose the supervisor metrics to display the graphs. The metrics will also be available to select when building dashboard graphs.
