Configuring the agent to monitor directories
1. Configure /etc/sd-agent/conf.d/directory.yaml
- directory: "/path/to/directory"
- directory: "/path/to/another/directory"
- Important: the sd-agent user must be able to read the given directory
- If you wish to specify other details such as recursion, patterns and gauges by amending the rest of the config file as necessary
- If you want to monitor two or more directories you need to ensure you have agent and plugin version 2.03 or above installed.
2. Restart the agent
sudo /etc/init.d/sd-agent restart
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:
directory ----- - instance #0 [OK] - Collected 1 metrics & 3 service checks
You can also view the metrics returned with the following command:
sudo -u sd-agent /usr/share/python/sd-agent/agent.py check directory
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 Disk metrics to display the graphs. The metrics will also be available to select when building dashboard graphs.
