Hi Tobi, Thanks much for the reply. I am gathering the counters via SNMP and sticking them in the RRD. It could certainly be my script is doing something strange or the counters on the device are bad. Here is an example:
1177476720: 9.4890612231e+06 2.9579036894e+06 1177476780: 8.5973761145e+06 2.5438812261e+06 1177476840: 1.1431781896e+07 2.4706615931e+06 1177476900: 7.4283981724e+06 1.6079156964e+06 1177476960: 6.4564314793e+06 1.3670967431e+06 1177477020: 7.3552319106e+06 1.5764984066e+06 1177477080: 7.5163364545e+06 1.8946703756e+06 1177477140: 8.8674587301e+06 2.9133983388e+06 1177477200: 8.8006863297e+06 2.4467189794e+06 1177477260: 7.8335465325e+06 3.4685346764e+06 1177477320: 7.0441856350e+06 4.4907708048e+06 1177477380: 5.0908686855e+06 2.6347848034e+06 1177477440: nan nan 1177477500: nan nan 1177477560: nan nan 1177477620: nan nan 1177477680: 2.8324705690e+08 1.6997104436e+08 1177477740: 2.9551147168e+07 1.8751196979e+07 1177477800: 1.0710302450e+07 7.3736138421e+06 1177477860: 7.2621223932e+06 6.1738161450e+06 1177477920: 1.3439222568e+07 5.0075043135e+06 1177477980: 1.1995400814e+07 3.4084870120e+06 1177478040: 1.1174723730e+07 4.2610384889e+06 1177478100: 7.7140599417e+06 4.9523913324e+06 1177478160: 1.0547613079e+07 3.4652299262e+06 1177478220: 7.3043887142e+06 2.2552235838e+06 1177478280: 9.3090210810e+06 5.2120493205e+06 You can see just after the nan's I get a reading that is an order of magnitude higher then everything looks fine. Would you expect that RRD would be able to deal with devices going away for short periods then re-appearing? Thanks Chris On 4/25/07, Tobias Oetiker <[EMAIL PROTECTED]> wrote:
Hi Chris, there is no such function within rrdtool, but If you read counters of your device I can not see how you get this spike ... if you calculate information externally, it may be that the external calculation is to blame ... cheers tobi -- Tobi Oetiker, OETIKER+PARTNER AG, Aarweg 15 CH-4600 Olten http://it.oetiker.ch [EMAIL PROTECTED] ++41 62 213 9902
