Scott's Perfmeter demo

--------------------------------------+|||||

Hi. This is a quick presentation of Perfmeter for those who haven't seen it. I run with a 5-second sampletime.

[perf image] This is Sonic -- things looked a little boring, so I ran two applications (one "niced").

cpu utilization

Same as above, except I've scrolled back. (The time for the rightmost sample drops onto the legend).

cpu utilization

Yikes! Ultra's Down! Actually, this is just a simulation -- I killed the statistics-gathering program. (My pulse doubles when I see this. )

cpu and disk utilization

Ultra, humming along. The blue stats are disk 3, our new 9Gb drive. The green stats are disk 2, the "old" news drive.
Activity when this snapshot was taken: Besides spooling news (which is mirrored on the old drive), I'm running "expireover" to bring the overview files into a more consistent state.

cpu and disk utilization

The web server isn't very busy at 7:30am.
