What logs are the basis for the CPU and Network analytics?
I first posted a question on ServerFault (so far no replies). I won't repeat the problem description here, as you can just read it on ServerFault. But I realized that a Linode-specific question is related: When I see the analytics on the Linode dashboard, I know they must be aggregated from logs, and those logs might also have more information about what processes were using the CPU or sending packets to/from the network. Can someone point me to potentially relevant log files to find out what crazy thing happened on my server for several hours yesterday?
If you haven't reviewed it yet, the Investigate the cause of high CPU usage? Community Question post should be a great primer. There is also the How do I check my server’s log files? post that covers reviewing service logs. Unfortunately, if you don't have a monitoring service set up, it's usually hard to pin down what happened to a Linode after the fact like this. Best of luck with the service logs, though!
