Log Analytics Metrics/Counter for Memory & CPU Load

[PrashantM2495]

Hi all, 

I am looking for some of the Azure Metrics/Counters for Windows and Linux VMs to replace existing monitoring tool and looking for equivalent Metrics in Azure 

Metrics	Windows VMs	Linux VMs
Physical memory (Bytes)
Pagefile (Bytes)
Virtual memory usage (Bytes)
Physical memory usage (Bytes)
Number of physical CPUs (Number)
Number of Logical CPUs (Number)
Processor queue length (Number)

It would be great help if anyone of you can suggest on these.

Best regards,

Prash

@PrashantM2495 Hi, once you have a Log Analytics workspace, and you've added your machines to the workspace, you can go to "Advanced Settings->Data->Windows Performance Counters" and add performance counter as you would in windows. By default a number are preconfigured, but more can be added in the selector. See here https://docs.microsoft.com/en-us/azure/azure-monitor/learn/quick-collect-azurevm

You need to think whether you want to monitor the number of CPU's though. Your type of Azure VM dictates that.

Hi @PrashantM2495 ,

Not all operating systems log the same data. You can see the full list of Windows and Linux collected counters in this article. I've used this query to collect all the perf counters reported today on the demo environment, and I've added the OS/Platform of each one for your convenience. It's not an exhaustive list as shown in the article, but a good way of reviewing what type of data your environment currently collects. As mentioned in the other reply to your question, that's configurable. Note that Kubernetes nodes and containers have yet additional counters, also interesting
