Performance counters bug for the cluster?
February 14th, 2008
Filed under: Bugs, VMware, performance
Today I noticed the following in a ESX 3.5 and Virtual Center 2.5 environment: When you check the performance of the memory(past day) on the cluster the minimum and maximum is way more than expected. In this case the minimum is 66,9% and the maximum 106,01%. This cluster has around 64GB of memory and there’s only around 30GB assigned, nowhere near the 66,9% or the 106,01% for that matter. Anyone who can confirm this behavior or even better explain it. I’m afraid it’s a bug…

Hey Duncan,
I can confirm your suspicion.
When I’m having a look at the past day’s memory performance, VI claims having an average memory usage of 258.50%, a maximum of 269.06 and a minimum of 133.31.
As the chart only shows values from 0 - 100 %, so I don’t even see a graph…
Even if all VMs would have used their maximum guaranteed RAM + overhead we’d have less than 120 of 144 GB RAM in use.
Bye
