Then you need to define one or more DSs, and here you need to define "heartbeat" - how long you can go between samples before the data is deemed to be invalid. Again, this is defined in seconds. And lastly, define one or more consolidation functions (CF). I thik this is where you are getting confused, as "0.5" and "0.25" sound like xff values : "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." A value of 0.5 means that HALF of the values in the consolidation interval may be unknown before the whole interval is considered unknown. _______________________________________________ rrd-users mailing list [email protected] https://lists.oetiker.ch/cgi-bin/listinfo/rrd-users
