I have converted a bunch of MRTG files to RRD and upsized the RRDs to keep 2 years worth of 5-minute averages. I keep 10 years worth of 24 hour averages. The problem is that the monthly and yearly graphs want to look at the 5 minute data instead of the RRA that's averaged over a day.
For an example, see: http://stryper.uits.iu.edu/~monitoring/mrtg-monitors/abilene-rrd/data/demonstration.cgi?city=wash&network=max&data=bits I upsized the RRD files about two weeks ago. This inserts empty 5 minute data for the prior 2 years. When RRD chooses the RRA to look at when doing a yearly graph, it appears to be looking at the 5 minute data, solely, and not the daily averages. This makes it look like there's no data collected before the day I upsized, which isn't true. I've seen this question before, but no reasonable answer. Is there any way to specify the resolution to be used when graphing a time period- similar to the rrdtool fetch function? One solution I've seen posed is to run through your upsized RRDs and grab the daily data and stick it in all 288 5-minute intervals in that 24 hour period. Aside from being tedious, it doesn't address the problem of computational overhead that looking at 5-minute RRAs over hourly RRAs introduces. It takes quite a while to generate the graphs. Is there any other way to do this? If not, can I put in a feature request for a "resolution" option for graphing? -Chris Chris Robb Indiana University Global NOC Abilene/TransPAC Network Engineer [EMAIL PROTECTED] Desk: 812-855-8604 Cell: 812-325-8199 -- Unsubscribe mailto:[EMAIL PROTECTED] Help mailto:[EMAIL PROTECTED] Archive http://www.ee.ethz.ch/~slist/rrd-users WebAdmin http://www.ee.ethz.ch/~slist/lsg2.cgi
