- directory: /var/spool/postfix
- Important: the sd-agent user must have sudo access to run this plugin. See sudo access for more info
2. Restart the agent
sudo /etc/init.d/sd-agent restart
sudo systemctl restart sd-agent
Verifying the configuration
Execute info to verify the configuration with the following:
sudo /etc/init.d/sd-agent info
If the agent has been configured correctly you'll see an output such as:
postfix ----- - 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 postfix
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 postfix metrics to display the graphs. The metrics will also be available to select when building dashboard graphs.
