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.

	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.

Some folks have asked where to get this perfmeter -- and to be honest, I don't remember where it came from. It's in /usr/openwin/bin, so I'm pretty sure it came with the Linux openwin distribution. I've been running the same a.out binary since Linux 0.99.something -- here are the (frightening) details: $ file perfmeter perfmeter: Linux/i386 demand-paged executable (ZMAGIC), stripped $ strings perfmeter | fgrep '.so.' /usr/openwin/lib/libxv3.so.3 /usr/openwin/lib/libolg.so.3 /libX11.so.3 libc.so.4 $ strings perfmeter | fgrep 'Jump' DLL Jump 3.0 DLL Jump 3.0 DLL Jump 3.0pl1 DLL Jump 4.4pl1 $ uname -a Linux pengo 2.0.0 #11 Thu Jun 13 11:32:08 PDT 1996 i586 Your # tar -ztvvf a.out/rstat.tar.gz -rwxr-xr-x root/root 29700 Jun 19 21:34 1996 perfmeter -rwxr-xr-x root/root 13312 Jun 19 21:37 1996 rpc.rstatd
