The icmpStatsTable refreshes every 5 seconds, so the table might not be refreshed after you ping the NUT and before you query for icmpStatsInMsgs. You must wait 5 seconds after the ping to get correct value of the icmpStatsInMsgs. Alternatively, you can turn off the caching. Run following command after snmpd startup (modify the authentication details, if needed). It sets cache timeout of icmpStatsTable to 0, i.e. disables caching. snmpset -v2c -c public localhost nsCacheTimeout.1.3.6.1.2.1.5.29 i 0 Thanks, Jan the case pass, when setup snmpset -v2c -c public localhost nsCacheTimeout.1.3.6.1.2.1.5.29 i 0 5 seconds cache timeout is recognized as sufficient for generic usage and setting lower cache timeout could have performance impacts. Since this behavior can be disabled if someone really needs it (using the magic snmpset), I think there is nothing to fix. |
