Re: Why does VM Guest Memory Utilisation Differs Memory utilisation report in vCenter Server

Hi @rickardnobel,

 

First off thanks for taking time to help me out. Right now, i can't put screenshots here for some reasons.

 

But to clarify things further and to give you prceise information; here is what exactly I am looking at and wondering:

 

Saw Task manager Memory and CPU usage and noted usage as about 40% for Memory and CPU for about 5%, then navigated to Perfmon tool and set user defined Data collector for Counter logs. And had Memory and CPU of Windows VM to get values logged at every 5 mins, and prepared a excel file with the values obtained from CSV file generated by Data collector. Now it too shows memory usage is about 40% and CPU as about 5-6%.

 

Now the big part plays: when I log into vCenter Server and see Performance tab for ESXi Host and Windows VM Performance Tab, it reports the Memory usage as 20% and CPU about 4-5%, Now my question/ confusion is, why does the memory reports from in Guest VM and vCenter Server reporting differs.

 

If, still need graphs, i will definitely put them up here. But I need a clear justification for the question. should the swap in and swap out are making the difference or what could be the causes.

 

 

Cheers!
