Hello Arabsoft-ACS,

As per SCOM's documentation, the "Total Query Received" is a measurement of the amount of queries received by the server.

This has no meaning in percentage, so it is weird that you see 100% in this context, as you should see a total number.

Can you elaborate on what exactly you see?

I am monitoring the DNS performance using "Performance Monitor", after getting the notification from SCOM. Please find attached.

Hi again Arabsoft-ACS,
The yellow graph in your screenshot is because of graph scaling, as the vertical axis is marked 0 through 100, and the value of the graph is around 64000.

Notice that the scale of the yellow graph (at the bottom is 1.0).
In order to see the graph properly, change the scale to 0.001 (so that the effective value will be 64)

This is how to change the scale:
Right click on the line of the yellow graph
Choose PropertiesIn the System Monitor Properties window go to the Data tab
Select your counter (in this case you have only one)
Select 0.001 in the Scale drop-down list
Click OK
