Server Monitoring

Watching incoming HTTP request in real time, so I can gauge the current demands on the server.

Monitoring the mail log in realtime, watching spammers attempting to connect, and which ones make it through. There's a problem with my (dv) where certain mail connections cause a server spike, so I try to catch them here.

Running "top", which gives me a list of processes and who's hogging the CPU. Updates every 3 seconds.

Monitoring /proc/user_beancounters, which tells me how much memory is being used by my (dv). What's important is to keep the FAILCNT numbers (right column) zero. Here you can see that interprocess communication is blowing through the allocated buffer (it was due to an evil wordpress plugin)

Running Mint to give me the overall sense of what the average pageload-per-hour. The old server would cry bloody murder at 800+ pageloads/hour, but this was due to inefficiency in my WordPress and Mint install that I've since cleaned out.

I've been tuning my new Media Temple (dv) Base, which has 256MB of memory available. I've been tweaking it so the base installation actually runs within the 256MB limit. The number of terminal windows I have up while relearning how to do this reminded me of the 90s, when I was doing more stuff with X as my daily GUI.

Machine thought in digital bliss, all knowledge
stored in memory banks equal to the Universe.
Machine had learned how to think for itself
but was like an unloved child, left on the shelf.
A sentient being with nothing much to do.
Machine was bored…Source

Thank you for this very interesting screenshot. What command do you use to monitor the incoming HTTP requests and the mail log in real time?

Dan: I piped tail through grep to match specific patterns in the log files, and had it emit only those matching lines.
