In addition to what Steve already said: Monitor your RRD file. Look for the counter values being put in, and the timestamps this happened (rrdtool lastupdate, or rrdtool info) Do the timestamps have expected values? If not, your crontab may need to be altered. Then look at the counter values being collected. Do the computations yourself (subtract previous counter value from the current counter value, subtract previous timestamp from the current timestamp, compute delta(countervalue)/delta(timestamp). Is the result close to what you expect to get, or is it close to what MRTG reports? This should help you figure out if it is collecting the counters which fails or if it is processing them further which fails. Also check your config file for typos. Use any tool you feel comfortable with, except your own eyes and brains; let the machine do the work (e.g. grep). Maybe you find a typo which results in different behaviour than you expect. That typo could be in another part of your config, overriding what you think you have set for DAS-c3229. _______________________________________________ mrtg mailing list [email protected] https://lists.oetiker.ch/cgi-bin/listinfo/mrtg
