NimbostratusSNMP CPU Usage
I'm curious what the difference between these two numbers is?
sysGlobalHostCpuUsageRatio (uses a 5-second polling interval)
sysGlobalHostCpuUsageRatio5s (also uses a 5-second polling interval)
...

mrosedale_13329This is exactly what I was seeing. I kept getting 1 for all of my f5's. Thanks for the answer. Though I still wonder if both sysGlobalHostCpuUsageRation and sysGlobalHostCpuUsageRatio5s use 5 second ratio is there really any difference between the two?- Derek_Stender_1The F5-BIGIP-SYSTEM-MIB file shows the following: sysGlobalHostCpuUsageRatio Description: "This is usage ratio of CPU for the system. It is calculated by (sum of detals for user, niced, system)/(sum of deltas of user, niced, system, idle, irq, softirq, and iowait), where each delta is the difference for each stat over the last 10-second interval; sysGlobalHostCpuUser5s Description: "The average time spent by the specified processor in user context for the system in the last five seconds." I've pulled some extra lines out of the full description, but hopefully that gives you enough information.
