Troubleshoot Azure Enhanced Monitoring for SAP
SAP Note #1999351 describes the process of troubleshooting issues with the Azure Extension for SAP. As the note states “to ensure full supportability of Azure for SAP workloads, it's crucial that the AzureEnhancedMonitoring service is correctly configured and that the Azure performance counters show up in the SAP OS monitor. In case there are no counters, supportability can't be guaranteed.“
If some of the monitoring data isn't delivered correctly, use the troubleshooting steps described here.
Set-AzVMAEMExtension and Test-AzVMAEMExtension show warning messages stating that Standard Managed Disks aren't supported
Issue
When executing Set-AzVMAEMExtension or Test-AzVMAEMExtension messages like these are shown:
WARNING: [WARN] Standard Managed Disks aren't supported. Extension will be installed but no disk metrics will be available.
WARNING: [WARN] Standard Managed Disks aren't supported. Extension will be installed but no disk metrics will be available.
WARNING: [WARN] Standard Managed Disks aren't supported. Extension will be installed but no disk metrics will be available.
Executing azperflib.exe indicates a non-healthy state.
Solution
Standard Managed Disks aren't delivering the APIs used by the monitoring extension to check on statistics of the Standard Azure Storage Accounts. This message isn't a matter of concern. The reason for introducing the monitoring for Standard Disk Storage accounts was throttling of I/Os that occurred frequently. Managed disks avoid such throttling by limiting the number of disks in a storage account. Therefore, not having that type of monitoring data isn't critical.
Windows performance counters don't show up at all
The AzureEnhancedMonitoring Windows service collects performance metrics in Azure. If the service isn't installed correctly or if it isn't running in your VM, no performance metrics can be collected.
The installation directory of the Azure Extension for SAP is empty
Issue
The installation directory C:\Packages\Plugins\Microsoft.AzureCAT.AzureEnhancedMonitoring.AzureCATExtensionHandler[version]\drop is empty.
Solution
The extension isn't installed. Determine whether this problem is a proxy issue. You might need to restart the machine or rerun the Set-AzVMAEMExtension cmdlet.
Service for the Azure Extension for SAP doesn't exist
Issue
The AzureEnhancedMonitoring Windows service doesn't exist. Azperflib.exe output throws an error indicating that the service of the Azure Extension for SAP isn't running.
Solution
If the service doesn't exist, the Azure Extension for SAP isn't installed correctly. Reinstall the extension by using the steps described earlier. After you deploy the extension, after one hour, check again whether the Azure performance counters are provided in the Azure VM.
Service for the Azure Extension for SAP exists, but fails to start
Issue
The AzureEnhancedMonitoring Windows service exists and is enabled, but fails to start. For more information, check the Application event log.
Solution
The configuration is incorrect. Reinstall the extension by using the steps described earlier.
Some Windows Azure performance counters are missing
The AzureEnhancedMonitoring Windows service collects performance metrics in Azure. The service gets data from several sources. Some configuration data is collected locally, and some performance metrics are read from Azure Diagnostics. Storage counters are used from your logging on the storage subscription level.
If troubleshooting by using SAP Note #1999351 doesn't resolve the issue, reinstall the extension by using the steps described earlier. You might have to wait an hour because storage analytics or diagnostics counters might not be created immediately after they're enabled. If the problem persists, open an SAP customer support message on the component BC-OP-NT-AZR for Windows or BC-OP-LNX-AZR for a Linux virtual machine.
Linux performance counters don't show up at all
A Daemon collects performance metrics in Azure. If the daemon isn't running, no performance metrics can be collected.
The installation directory of the Linux Azure Extension for SAP is empty
Issue
The directory \var\lib\waagent\ doesn't have a subdirectory for the Azure Extension for SAP.
Solution
The extension isn't installed. Determine whether this problem is a proxy issue (as described earlier). You might need to restart the machine and/or reinstall the extension by using the steps described earlier.
Some Linux Azure performance counters are missing
A Daemon collects performance metrics in Azure, and gets data from several sources. Some configuration data is collected locally, and some performance metrics are read from Azure Diagnostics. Storage counters come from the logs in your storage subscription.
