Resolved How to display CPU usage values in percentage?

[Plesk Noob]

Hello,

Currently on my Server Information page it shows my cpu stats in the following format, i am not sure what these numbers indicated, is it possible to display CPU stats in percentage format in Plesk onyx?



OS ‪: Ubuntu 14.04.5 LTS‬
Plesk Version : Plesk Onyx Version 17.0.17

Regards,
S.M.

According to the Plesk Documentation and Help Portal, the "CPU Usage" displayed is "the average usage of the server CPU (in %)"

CPU Usage

I don't think thats correct, cause when it showed usage "6.x" my server was almost inaccessible, it way fully overloaded. so this value probably isn't in percentage and its quite confusing, i am not sure what does it indicates.

The cpu usage gives you the load of the total of all cpu cores where 1 is 100% of one core. A cpu load of 4 means that 4 cpus would be needed to instantly process all requests. So a cpu load larger 1 is not an issue on systems with multiple cores.

Example:
On a 12-core-processor a cpu load of 6 means that the system has a 50% overall load.
On a 4-core-processor a cpu load of 1.10 means that the system has a 27.5 % overall load.
On a single-core-processor a cpu load of 0.86 means that the system is experiencing an 86% load (too much, see below).

Normally you should make sure that a cpu is not experiencing loads above 70% as collisions of processes increase exponentially. A system can operate trouble-free with a 60% load for example, but at 70% it becomes a lot slower than an increase of 10 percentage points would suggest.

For your numbers from above (0.86, 1.17, 1.20): They are just barely enough if you have 2 cpu cores available. If you only have a single core, you should move up to a better machine or virtual host.

Your answer makes perfect sense
I have a 12 Core CPU, so at 6-7, it was around 60% in use.
Now i get it,
Thanks so much
