there is a VM that we have running in one of our clusters in vCenter. we have solarwinds monitoring the VMs and we have the Solarwinds virtualization manager plug-in. Solarwinds reports that a single VM is utilizing 98% of the 8 GB of memory and when you log onto the VM's operating system performance monitor, it reports the same statistics
When you view the performance for that VM in vSphere, it reports that the active memory is approximately 3.5 GB of memory but the Consumed memory counter does state that it is using close to all of the 8 GB. i'm curious why there is such a huge difference between what vSphere is reporting and what the VM and the monitoring software Solarwinds reports.
no end users are reporting any performance issues with that VM but that is not to say that there aren't any.
