sysreport of affected system
The problem is that net-snmp-5.0 (=RHEL4) shows average length of run queue instead of proper hrProcessorLoad value (=the average, over the last minute, of the percentage of time that this processor was not idle.) - the value you see on RHEL4 is completely wrong. In net-snmp-5.3 (=RHEL5) upstream decided, that it's better to report nothing than report completely misleading value - you do not see hrProcessorLoad in the walk. Later on, upstream finally decided to implement it properly. The implementation is not perfect - it periodically gathers CPU load and estimates the one-minute average in a way, that the value is not available for first minute after snmpd start. After the first minute, it shows correct values. I'll try to port it back to RHEL 5. Note to self: look at SVN commits 15026-15027, 15030, 15100 and maybe more. Created attachment 294204 [details]
