Configuring the agent to monitor Postfix
1. Configure /etc/sd-agent/conf.d/postfix.yaml
- 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.
Please refer to the metrics conversion document to map old metrics names to the new metric names.
