per core CPU usage
Hi iflyF16,
You can retrieve per-core CPU usage details for an Azure VM using Azure's monitoring tools. Follow these steps:
- Log in to the Azure Portal.
- Navigate to Virtual Machines and select your Azure VM.
- In the left menu, go to Monitoring and choose Metrics.
Concerning your second question, CPU usage and per-core CPU usage may differ.
CPU usage is typically presented as a percentage of the total capacity of a single CPU core. In multi-core systems, the percentage can exceed 100%, such as if 3 cores are at 60%, resulting in a total CPU usage of 180%.
In contrast, per-core CPU usage provides the utilization for each individual core. This is valuable for understanding how your application utilizes specific cores. For instance, if one core is at 15% usage and another at 5%, it suggests varying levels of utilization across cores.

- Thanks for the detailed guidance on retrieving per-core CPU usage in Azure VMs through the Azure Portal's Monitoring tools. Your step-by-step instructions will be beneficial.
Regarding the distinction between CPU usage and per-core CPU usage, your explanation clarifies the difference for me. It's insightful to note that while CPU usage represents the overall load on all cores, per-core CPU usage delves into individual core utilization, offering a more nuanced understanding of workload distribution. This distinction is valuable for optimizing performance across specific cores based on application requirements. Great insights, much appreciated!
