Hi All, The RRD documentation "reccomends" setting MIN and MAX values for all data-sources when creating the RRD files. But all the examples show this with a GUAGE DS-type, where MAX is obviously the biggest value the counter can ever hold.
How is MAX interpreted for a COUNTER DS-type? Does it represent the maximum increment over the previous data-point? What if the previous data-point is two "steps" back in time? Is the MAX a maximum per-step increment? Or is it configured as a rate directly and multiplied by the step interval and the number of steps? For example, I'm just starting to experiment with RRD, and I'm logging sysUpTime from SNMP as a sanity check. The rate-of-change of the counter is one-second-per-second ;) Should I declare the DS as rrdtool create --step 60 DS:sysUpTime:COUNTER:360:0:60 or rrdtool create --step 60 DS:sysUpTime:COUNTER:360:0:1 ??? Currently I have it declared at 600 to be on the safe side, and it works fine ;) But my ignorance is a factor of 60! I have other counters that I want to limit and plus-or-minus 60000 % seems a bit unreasonable ;) thanks Ciaran -- 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
