The Server Snapshot feature includes a breakdown of all the processes running on the server at that particular moment in time.
You will notice that the totals in the table do not always add up to 100%. Indeed, they usually do not. This is because the percentages are not showing the current moment in time percentage usage but rather usage over time, since the process started. This gives a more accurate representation of how the server resources have been used by that process.
CPU usage
This is the CPU time used divided by the time the process has been running (cputime/realtime ratio), expressed as a percentage. The CPU usage % value displayed here is different from the CPU load decimal value shown on the server view graphs.
Memory usage
This is the ratio of the process's resident set size to the physical memory on the machine, expressed as a percentage. The memory usage % value displayed here is different from the memory usage MB values shown on the server view graphs.
