Im curious as to how to track down who is responsible for increasing loads on a server? I have attached the nodeworx monitoring png, please look just before midnight there was sharp increase in usage then all shuts down and restarts - thanks to SIM.
I looked at individual usage stats for each site since I only have 10 sites on there currently. None of them have any sharp peaks that match the png I uploaded here. This has only happened once before a couple of weeks ago, causes loads to go through the roof rendering the server inaccessible. Could it be interworx? How can I investigate further to find the source of the problem?
Thanks!
