Hi, I am monitoring a cluster with Ganglia v3.0.7. In it there are some hosts with one processors (let's say 4) and some with 8 processors (let's say 4). When viewing the cluster page there are four graphs at the top of the page: load, CPU, memory, and network. These graphs reflect the state of all hosts in the cluster. I have noticed that the CPU plot displays the percentage of CPU use per host, not per processor.
If all eight hosts (36 processors) are busy, the load is 100%. If they are idle the CPU percentage is near 0%. Both of these are correct. However, if the four single processor machines are 100% utilized and the multiprocessor machines are idle the CPU plot reports 50% utilization. The same is true if the 4 multiprocessor hosts are busy and the uniprocessor hosts are idle. These values are incorrect. How can I scale the % CPU value by the number of processors? Thanks, Rich ------------------------------------------------------------------------- This SF.net email is sponsored by the 2008 JavaOne(SM) Conference Don't miss this year's exciting event.
