Hi,
Apologies in advance for sounding ignorant to SAM's functionality v.s. VMan, as I am a few years/versions behind on Solarwinds.
I was approached with a problem this morning that I am having difficulty answering with my own research. The issue is memory usage representations out of Server and Application Monitor, versus Visualization Manager. See below screenshot from SAM for the Physical Memory in use:
SAM showed us this particular Virtual Machine as having used 8.2 GB of Memory, out of an available 18GB. Over the course of this morning, It consistently "used" 8.2 GB. However, In the screenshot below for this node on VMan, the active mem during this time was only 2.48 GB:
So I went and compared details in SAM further for the Virtual Machine. The below shot shows again that at the time I checked, only 11%, or 2GB is in use of the available 18GB.
In VMan, the VM shows again having 18GB allocated RAM, with 11-12% usage, consistent.
So I then checked the ESX Host (below)... 50% utilization.
So I get that SAM and VMan play on different sides of the sandbox, etc. But does this mean that SAM is actually reporting to me on physical memory of the host, rather than the VM? Despite the Volume details layout suggesting that I am looking at the "physical memory" of the Virtual Machine? I find this very confusing if so, but perhaps I am crossing wires here?
I also would like to know if I am able to customize then the Disk Volumes widget in SAM for nodes to display Consumed Host Memory v.s. Active Guest Memory? This may not be possible in SAM, and I know it's available in VMan for Hosts, but I do not see it for VM's specifically. Thoughts? The reason I am looking for this data is so I can then attempt to report out on allocation of RAM on VM's and HOST against actual utilization, so that we can determine what (if any) VM's need to be scaled back on resource allocation.
Thank you for your help!
