Question Advanced Monitor /Grafana: Processes graph inaccurate?

[Azurel]

MRTG shows me peaks in the processes. Grafana doesn't seem to be interpreting this adequately. I had someone who made an extremely high number of pageviews and thus loaded the server. In MRTG I recognized the problem immediately. See right border. In Advanced Monitor I do not recognize it at all. I'm not saying the MRTG is better, but if there are problems, I can see it. Not with Advanced Monitor. I would like to use only Advanced Monitor instead MRTG.
