Oh, come on prisoner, it's not that bad - Don't cut yourself short. The lines in Zenoss that you are modifying are described on the RRD page:
> RRA:AVERAGE | MIN | MAX | LAST:xff:steps:rows > > xff The xfiles factor defines what part of a consolidation interval may be > made up from *UNKNOWN* data while the consolidated value is still regarded as > known. It is given as the ratio of allowed *UNKNOWN* PDPs to the number of > PDPs in the interval. Thus, it ranges from 0 to 1 (exclusive). > > steps defines how many of these primary data points are used to build a > consolidated data point which then goes into the archive. > > rows defines how many generations of data values are kept in an RRA. > Obviously, this has to be greater than zero. The line your looking to change is probably the first one: Code: RRA:AVERAGE:0.5:1:600 This line defines the primary data points because steps = 1. Since rows (the last number on the line) is the number of data values to keep, you just need to multiply the polling frequency (5 minute default) times the number of rows to determine how long the data is kept. The default of 600 keeps 5 minutes x 600 samples = 3000 minutes or 50 hours of data before it starts to consolidate. Increasing to 2400 gives you 200 hours of primary data before consolidation. Your next question is where to change the polling frequency? On the same page as the default RRD settings, there is a setting labeled "SNMP Performance Cycle Interval (secs)". That determines how often performance data is polled. -------------------- m2f -------------------- Read this topic online here: http://forums.zenoss.com/viewtopic.php?p=35472#35472 -------------------- m2f -------------------- _______________________________________________ zenoss-users mailing list zenoss-users@zenoss.org http://lists.zenoss.org/mailman/listinfo/zenoss-users
