I got itchy fingers over the weekend and decided to fix what wasn't broken and upgraded one of the older servers from Centos 5.2 to Centos 5.3. Following the recommended process of updating glibc and such before the rest, it appeared to work perfectly and rebooted without problem. [...]
Did anybody else have similar experiences with MRTG failing after the update and what was the simple fix? It does not make any sense that I have to jump through so much hoops to get just the default functionality back. Thus I believe there must be one small thing I'm overlooking.
Check the snmpd.options file (it can be at either /etc/snmpd/snmpd.options or /etc/sysconfig/snmpd.options depending on your system history). When I upgraded to 5.3 I found that it broke the options I was using to suppress logging of the SNMP polling. A set of options that work are
OPTIONS="-Ln -Lf /dev/null -p /var/run/snmpd.pid"
