CPU usage readings

[Chris1]

I use a few different tools to monitor aspects of my servers however I'm just wondering how the Android Plesk app records CPU load average statistics?

The reason why I ask is because the Plesk health monitor and my Cacti graphs indicate that my average CPU usage is approximately just under 5% whereas the Android app is always stating much higher figures such as 30-40%.

Does the Android Plesk app only read off one CPU core?

Plesk Mobile app must show the same values as Plesk on Tools & Settings > Server Information page.
On Linux this is UNIX Load Average. Percent sign in such case is a bug (PMBL-478), it will be fixed in the next update.

Ahhh I see. So at the moment in my Plesk mobile app it states 3% on a 1min average. Does this just mean a load average of 3 or 0.03?

After doing some reading, it seems that the above could mean that in the past minute, 3% of one core was utilized?

This means a load average of 0.03.

Roughly speaking, yes.
