Jochen,
I thank you once agian for turning me on to rrdtool, its been great so
far. I just wanted to know if you ran into the same problem that Ive
encountered.
This is what I'm doing;
1) snmpCollect collects and saves all data from OID.#! files.
2) I then read/dump the OID.# data to create the rrd's.
3) webpage displays on-the-fly graphs.
The problem happens during step 1. My network devices have 32bit
counters so once or twice a day on busy ports the counters reset or
wrap. This causes a gap in the rrd database. Have you run into this
problem?
Also I'm wondering has anyone change the mib.coerce data file
to store GAUGE instead of COUNTER type data to resolve similar issues.
CoolC
