Question Detect what caused Apache and CPU to spike for an hour

[SquanchIt]

Hey guys,

So the monitoring tool is reporting that the server's CPU, Apache, Nginx, as well as disk read and write spiked for about an hour an a half.

What's a good way to detect which site was responsible for the heavy load?

Thanks!

Edit: I checked the bandwidth on all the domains and daily average statistics, nothing unusual there.

Hi SquanchIt,

Since Advanced Monitoring 1.4.0, it is possible to show CPU/memory usage per subscription. This feature is based on metrics that are collected by Cgroups Manager. It does not help to find out what is happened in the past but could help with possible future questions about websites' usage.

Hi AYamshanov,

Thank you for your response.

While your solution doesn't help me with the issue I am having since those spikes tend to happen while I am asleep. This is still a cool feature that I want to enable on my server. I have less than 10 subscriptions on my server, so I am surprised that it's not already enabled, so I tried enabling it manually by adding the following lines to panel.ini:



but that didn't seem to work for some reason. Do I need to restart the server?

Thanks!

Oh I see now that it's a paid extension.

Thanks anyway
