RRDTOOL gurus,
We have noticed that our installation of MRTG+RRDTOOL+14all.cgi shows a huge spike on our Cisco interface graphs whenever a "clear counters" is done on the device. This is becoming a big problem for us, as we have just implemented a new NMS which clears all counters once per day. We run MRTG with RRDTOOL and 14all.cgi, and this problem is seen in the latest versions of each. MRTG alone does NOT exhibit this behavior. I know this is an issue of the OID counter wrapping, but why is it that MRTG alone handles this and the RRDTOOL implementation does not. Is there a way to tweak RRDTOOL or 14all.cgi to better handle this wrapping situation? More info on my setup: - Switches are Cisco Cat 4006 and 5XXX - Our NMS is resetting all port counters by doing an snmpset on private.1.9.5.1.1.13.0. Most people do not believe me, but this DOES reset the ifOctets value to 0, by design. Thanks in advance...
