Measuring Apache Performance

Question

As our servers gets busier I'm increasingly interesting in monitor what's going on over time, we have some our host offers some crappy graphs which show CPU usage and Memory over time but there not really telling me much.

What sort of high performance tools are available to accurately monitor Apache?

Answer 1

You can setup rrd to store data and create graphs based on data you send it. I suggest parsing data from the apache logs and from the ps command.

You can also use the cacti package to create an interface to rrd.
