I am collecting SAR data on a couple of my test systems and am wondering if anybody has had success in plotting that data out with gnuplot or the like. I am new to gnuplot, so I figure I can eventually learn it over time. I have a copy of Oliver Masse's sargraph script, but it don't like AIX 5L with the extra columns and the "System configuration" line. If nobody else has cracked this nut, then I will spend the time to modify the sargraph.ksh script. I just don't want to re-invent the wheel if it has already been invented.

Thanks to all who respond,

Scott

Why not use nmon and either graph with the nmon Analyser via Excel or use nmon2rrd to crete .gif images?

Unless you are really bored or want to know gnuplot first hand.

Find nmon at http://www-941.haw.ibm.com/collaboration/wiki/display/WikiPtype/nmon

or

The article at http://www-128.ibm.com/developerworks/eserver/articles/analyze_aix/

My peer and I took separate directions on this, his was nmon and mine was sar. After he processed nmon data through the analyzer and produced management-friendly graphs and charts, we determined that nmon was the way to go. Now I am looking for a way to go from nmon data format straight to charts and graphs in html. Does nmon2rrd do this? I will take a look at it once I am done typing.

Thanks for your help!

For completeness, sarcheck (www.sarcheck.com) analyzes sar-data and plots it using gnuplot. Also puts some recommodations for tuning.
The bad news: costs money (although you get a 30 days trial licence for free). Good news is that for partitioned systems (p570 in our case) you need only one licence per system, number of partitions doesn't matter.

Nmon + nmon2rrd appears to be the combination I am looking for, but when I run my nmon data through nmon2rrd, I end up with a bunch of blank charts on the web page. They are all titled properly, but no data. Also, my x-axis only shows 3 hours, instead of the full 24 included in the data file. Anybody else experienced this?

Any direction is appreciated.

What versions of nmon and rrdtool are you using? They should match.

It sounds like the nmon sampling interval does not match the sampling interval assumed by the rrdtool. Check the time stamps in rrd_create file and rrd_graph files (both created created by nmon2rrd).

I have just up loaded a nmon sample file that does work with nmon2rrd to the nmon website at http://www-941.ibm.com/collaboration/wiki/display/WikiPtype/nmon

The sample file is called test.nmon.gz
Find it below the nmon2rrd download.

Most failures are
1) not capturing enough data snapshots (try 200)and
2) not checking the log files (xxxx.log) for errors

Please remember this is a working example rather than a product.
If you find problems or errors you need to work a solution yourself by looking at the nmon2rrd source code, checking the nmon data file and learning up on rrdtool.
