This is by design to help you look for issues or patterns over If you run the query in your log analytics log window and have servers over 85% CPU usage you should see something like this.Įven though the server is not currently over the percentage it is still showing The last line then renders a nice chart for you. You could change the step if you like, I found 10 minutes to be a good fit for me. You then make a series of the data on the time generated from the time you set above to now (as in when the query runs) and step it by 10 minutes. You then do a join on the initial query with this query, which is basically the same, but without the summarize as it’s not needed now. To do this go to your Log Analytics Workspace click Advanced Settings, then click Data, now click Windows Performance Counters, and finally click Add the selected performance counters.

Basically, if you have not enabled performance counters in you Log Analytics Workspace you will need to.

I will go through the query I use and will show you how to pin it to a dashboard, but first, we have some prerequisites to get out of the way first. This post will focus on monitoring CPU usage. So I thought perhaps more people would like to know this too, hence this blog post. At one of my Azure user groups, someone asked me about monitoring servers using Azure.
