Health Monitoring

SymeonM

New Pleskian
Hi,

I would like to ask where I could find a detailed manual of the Health Monitoring of Plesk. I had a message that the cpu usage was at some point in red and I'm trying to understand the graphs.
I upload a file from the Health Monitoring of my server. Some questions I have are:

Apache CPU usage: 0.8% (green arrow down). Then at around 18:00 there is a peak. I suppose that 0.8% that it consumes the 0.8% of the CPU. The arrow that is down means that from previous instances it has been reduced? Furthermore what does 1.8k etc means, what User time % and what System time %?
Load average: 0.11 processes, what does the 0.11 means and what does 400m indicates?

The reason I'm asking is that at around 18:00-20:00, if you see from the graphs there was either a peak in the CPU or a notch in the memory. So, I'm trying to understand what all these graphs mean and then how to check the reason in the linux machine I have.

Thanks in advance
 
The user manual doesn't really contain any helpful information about the stats.

What is user time and system time?
