Configuring the agent to monitor individual CPU Stats

The sd_cpu_stats check is automatically installed and configured with the agent. There are no configuration options available.

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:

cpustats
-----
  - 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 sd_cpu_stats

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 cpustats metrics to display the graphs. The metrics will also be available to select when building dashboard graphs.
