All, I have been having this same problem see my earlier post: http://www.ee.ethz.ch/~slist/rrd-users/msg06675.html
I followed the suggestion of setting a minimum and maximum, with no luck. The counters are wrapping at 32-bit boundaries and when that happens it seems to be adding the wrap amount to the average, thus creating a spike. Any help would be greatly appreciated. --trey -----Original Message----- From: Tobias Oetiker [mailto:[EMAIL PROTECTED] Sent: Thursday, May 15, 2003 1:33 AM To: Lordy Cc: rrd-users@list.ee.ethz.ch Subject: [rrd-users] Re: Wrapping not working correctly Today Lordy wrote: > This is a log of the counter wrap and the according values from the rrdfile: > > TIMESTAMP : INPUT : OUTPUT (log) > 1052944620 : 26649774336 : 34299525336 > 1052944680 : 26653861104 : 83380896 > 1052944740 : 26657344136 : 214937496 > [...] > 1052931120 : 25223793736 : 34297051328 > 1052931181 : 25229329384 : 150880920 > 1052931240 : 25234327032 : 343693456 > > TIMESTAMP : INPUT(AVERAGE) : OUTPUT(AVERAGE) (rrd) > 1052944500: 3.5023817268e+04 1.1066858514e+06 > 1052944800: 6.5019546667e+04 6.1489146800e+16 > 1052945100: 9.9007487213e+04 3.0024917578e+06 > [...] > 1052931000: 9.3047440000e+04 3.2095458133e+06 > 1052931300: 8.1707626667e+04 6.1489146801e+16 > 1052931600: 7.2381360000e+04 2.9875407733e+06 > > Is this a problem with /proc/net/dev, rrdtool or just sh!t in -> sh!t out ? > > I'm really curious to hear any comments on this as rrdtool is supposed to > "handle wraps > gracefully" according to Tobi's earlier postings on this list. Lordy, for wrap detection to work, a min and max must be set, and the wrpas must happen at 32bit and 64bit bounderies, otherwhise it is sensible to just use DERIVE datasources with min set to 0 tobi > > Best regards, > Lordy > > -- > 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 > -- ______ __ _ /_ __/_ / / (_) Oetiker @ ISG.EE, ETZ J97, ETH, CH-8092 Zurich / // _ \/ _ \/ / System Manager, Time Lord, Coder, Designer, Coach /_/ \.__/_.__/_/ http://people.ee.ethz.ch/~oetiker +41(0)1-632-5286 -- 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 -- 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
