Okay, so I was graphing my system load in the usual manner (i.e. multiplying it by 100), and I ran into some issues graphing my hard disk size.
I'll detail the hard disk size in another email, as I think it's mainly because I was trying to graph things in bytes (rather than 1-k blocks), so that MRTG's built in kilo, mega, giga conversion would take place. Anyway, something about this convinced me to try RRDtool, and I've encountered a couple of problems with it. When I tried to graph load average with a decimal, I got the following error: ERROR: Cannot update /home/danm/public_html/mrtg/load.rrd with '1096129409:1.17:119' not a simple integer: '1.17' I thought this was supposed to be something rrdtool could handle? Additionally, the data type for all rrd's is set to "COUNTER" rather than what they should be (i.e. gauge, absolute) if those are set in mrtg.cfg Finally, it seems rrdtool is doing some math it shouldn't be, as when I do an rrdtool dump on the rrd, I get values like this: <!-- 2004-09-25 01:05:00 EDT / 1096088700 --> <row><v> 3.3526011561e-01 </v><v> 2.3121387283e-02 </v></row> <!-- 2004-09-25 01:10:00 EDT / 1096089000 --> <row><v> 1.3564795119e+00 </v><v> 2.8822080925e-01 </v></row> <!-- 2004-09-25 01:15:00 EDT / 1096089300 --> <row><v> 1.4741725009e+00 </v><v> 1.3540626533e+00 </v></row> <!-- 2004-09-25 01:20:00 EDT / 1096089600 --> <row><v> 1.4174337716e+07 </v><v> 1.4174339719e+07 </v></row> <!-- 2004-09-25 01:25:00 EDT / 1096089900 --> <row><v> 1.4410732367e+07 </v><v> 1.4410732085e+07 </v></row> <!-- 2004-09-25 01:30:00 EDT / 1096090200 --> <row><v> 4.8042286822e+04 </v><v> 1.4269472814e+07 </v></row> I'm running it every five minutes. It's adding one value to the database every five minutes. Why is it running averages? The resulting graph looks like this: http://www.gushi.org/mrtg/14all.cgi?log=load -Dan -- "The first annual 5th of July party...have you been invited?" "It's a Jack Party."
