The CPU statistics for each account’s server resource usage are generated on a quite complex principle.
The graph is split into two smaller graphs – the upper one shows the CPU time for your user. This is the average time a script started by your account takes to execute on the server. The time is in CPU ticks/cycles. The numbers on the left side of the graph show the number of CPU ticks and the digits at the bottom show the time on the server.
The lower graph shows the number of executions per hour your account makes. The numbers on the left side of the graph show the number of executions and the digits at the bottom show the time on the server.
A simple example of an execution is when a visitor opens your website and your index file is loaded. This counts as one execution. The more visitors your website has, the more executions it will generate.
To view your resource usage, log into cPanel and scroll down to the Logs section and click on the icon for Resource Usage.
