We have a virtual machine sitting in a Vsan environment with 24GB of ram, with 4 virtual processors using an intel Xeon E5-2670 v3 2.3ghz. The current memory is at around 56% utilization and CPU goes between 4%-30% with some processes running. The OS is Windows 2012 R2.
Nobody is even using this server right now and when I log onto it by RDP via VPN it has a lot of occasions where the latency is ridiculous. It isn't my internet or our infrastructure bandwidth by what it seems, as other servers on the same VSAN are absolutely fine when we log on. Every I.T person working remotely who tried, told me they see the same issue. Right now if I click on file explorer, the instruction takes forever. But then, 5mins later if I do the same thing, the thing opens up fine. I just got kicked out of the RDP session and it retried and let me back in and did this 2-3 times over a few mins.
These things are difficult to diagnose but I don't want to reboot (I'm told this was done 3-4 days ago, possibly due to this happening previously). So my question is this: how would you diagnose using tools like Performance monitor or resource monitor (or any other tools)? What would you look for? And in doing so, what would you look for when looking and how would you determine if that's the thing causing the possible issue?
Can I look for something on network throttling on the Vmware side perhaps? Any help would be great. (I will also be trying to connect a monitor to Vsan hosts to see the same latency exists when directly on the server).
Any help would be greatly appreciated. Attached are some snapshots that may/may not help.Performance of Network monitor.jpgPerformance resource monitor.jpgPerformance tab server.jpg
