[Xymon] RRD Files Growing Large

[Dave "doughnut" Fogarty]

Yep.  That looks like it.  This is my config from Debian (both xymon 
versions: 4.3.17-6+deb8u1 and 4.3.28-2).

[]
         # 576 datapoints w/ 5 minute interval = 48 hours @ 5 min avg.
         RRA:AVERAGE:0.5:1:576
         # 576 datapoints w/ 6*5 minute averaged = 12 days @ 30 min avg.
         RRA:AVERAGE:0.5:6:576
         # 576 datapoints w/ 24*5 minute averaged = 48 days @ 2 hour avg.
         RRA:AVERAGE:0.5:24:576
         # 576 datapoints w/ 288*5 minute averaged = 576 days @ 1 day avg.
         RRA:AVERAGE:0.5:288:576


I think it's worth leaving as is, but if you're running low on space, you 
can use rrdtune to clear out some of the predictive data and even remove 
the RRA if you really want. YMMV
