Resource Monitoring with Plesk

Monitoring the resource usage on the server is vital to properly managing the system and your hosted accounts. To check the resource usage on the server you first need to log into the Plesk as the admin user. Once logged in, click Health and Monitoring in the main menu on the left hand side. This will bring up the following screen:

You will notice that there are 5 categories: Services, Disk, Memory, CPU, and Network. For each service the system gives detailed information regarding their resource usage. You can click the “+” (Plus Symbol) next to each category to view the individual stats for the specific category, and you can put a check in the box next to the individual stats to see a visual breakdown in even greater detail showing usage over time:
