-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I'm trying to log data from an explicit OID to track the number of packets that fail transmission on a wireless access point.
Using Net-SNMP, I'm able to extract information from this counter type and I see the value increment: $ snmpget -c public 172.16.0.92 .1.2.840.10036.2.2.1.3.1 iso.2.840.10036.2.2.1.3.1 = Counter32: 83484 $ sleep 120 $ snmpget -c public 172.16.0.92 .1.2.840.10036.2.2.1.3.1 iso.2.840.10036.2.2.1.3.1 = Counter32: 83488 I put together a simple mrtg.cfg to collect information about this MIB entry: $ cat mrtg.cfg WorkDir: /home/jwright/failedtx Target[172.16.0.92_1]: .1.2.840.10036.2.2.1.3.1&PseudoZero:[EMAIL PROTECTED] Title[172.16.0.92_1]: dot11FailedCount - excessive retries that failed to TX MaxBytes[172.16.0.92_1]: 4096000 And I am able to reference this file and collect the MIB data: $ /usr/local/mrtg-2/bin/mrtg mrtg.cfg Rateup WARNING: /usr/local/mrtg-2/bin/rateup could not read the primary log file for 172.16.0.92_1 Rateup WARNING: /usr/local/mrtg-2/bin/rateup The backup log file for 172.16.0.92_1 was invalid as well Rateup WARNING: /usr/local/mrtg-2/bin/rateup Can't remove 172.16.0.92_1.old updating log file Rateup WARNING: /usr/local/mrtg-2/bin/rateup Can't rename 172.16.0.92_1.log to 172.16.0.92_1.old updating log file $ /usr/local/mrtg-2/bin/mrtg mrtg.cfg Rateup WARNING: /usr/local/mrtg-2/bin/rateup Can't remove 172.16.0.92_1.old updating log file $ /usr/local/mrtg-2/bin/mrtg mrtg.cfg $ My problem is that the log file doesn't appear to be collecting the information properly. Each time I run "mrtg", the .log file is updated, but no previous statistics are collected. For example: $ head 172.16.0.92_1.log 1126832868 83493 0 1126832868 0 0 0 0 1126832866 0 0 0 0 1126832700 0 0 0 0 1126832400 0 0 0 0 1126832100 0 0 0 0 1126831800 0 0 0 0 1126831500 0 0 0 0 1126831200 0 0 0 0 1126830900 0 0 0 0 $ sleep 300 ; /usr/local/mrtg-2/bin/mrtg mrtg.cfg $ /usr/local/mrtg-2/bin/mrtg mrtg.cfg $ head 172.16.0.92_1.log 1126833288 83505 0 1126833288 0 0 0 0 1126833277 0 0 0 0 1126833000 0 0 0 0 1126832700 0 0 0 0 1126832400 0 0 0 0 1126832100 0 0 0 0 1126831800 0 0 0 0 1126831500 0 0 0 0 1126831200 0 0 0 0 $ For some reason, mrtg is replacing the previous logging entry instead of retaining the historical statistics. Did I not configure my mrtg.cfg file appropriately to collect information from this MIB entry?
