If you’re running a virtual machine (VM) on the Azure cloud platform, it’s important to monitor its CPU credit status to ensure optimal performance. CPU credits are used to provide burstable performance for VMs that are running in the Basic or Standard tiers of the Azure compute service. If your VM runs out of CPU credits, its performance may be impacted.
In this post, we’ll show you how to check if your Azure VM has run out of CPU credits using the Azure portal, the Azure CLI, and the Azure PowerShell module.
Check CPU Credit Status using the Azure portal
Here’s how you can check the CPU credit status of your Azure VM using the Azure portal:
- Go to the Azure portal and sign in.
- Navigate to the virtual machine for which you want to check the CPU credit status.
- Go to the “Metrics” section of the virtual machine.
- Find the “Percentage CPU Credit Balance” metric and see if it’s near 0%. If it’s close to 0%, that means the VM has run out of CPU credits.
Check CPU Credit Status using the Azure CLI
Here’s how you can check the CPU credit status of your Azure VM using the Azure CLI:
- Open a terminal or command prompt and sign in to the Azure CLI using the following command:
Copy codeaz login
- Once signed in, you can retrieve the CPU credit status of a VM using the following command:
cssCopy codeaz monitor metrics list --resource <vm_resource_id> --metric 'Percentage CPU Credit Balance' --time-grain PT1M --aggregation Average
Replace <vm_resource_id>
with the resource ID of the VM you want to check. If the percentage CPU credit balance is close to 0%, that means the VM has run out of CPU credits.
Check CPU Credit Status using the Azure PowerShell module
Here’s how you can check the CPU credit status of your Azure VM using the Azure PowerShell module:
- Open a PowerShell prompt and sign in to Azure using the following command:
sqlCopy codeConnect-AzAccount
- Once signed in, you can retrieve the CPU credit status of a VM using the following command:
sqlCopy codeGet-AzMetric -ResourceId <vm_resource_id> -MetricName 'Percentage CPU Credit Balance' -TimeGrain "00:01:00" -AggregationType Average
Replace <vm_resource_id>
with the resource ID of the VM you want to check. If the percentage CPU credit balance is close to 0%, that means the VM has run out of CPU credits.
In conclusion, monitoring the CPU credit status of your Azure VM is crucial for ensuring optimal performance. By using the Azure portal, the Azure CLI, or the Azure PowerShell module, you can easily check if your VM has run out of CPU credits and take appropriate action to avoid performance issues.
