As administrators utilizing Microsoft Azure Stack Hub, it’s crucial to understand how to collect diagnostic logs on demand via the administrator portal. These logs can offer valuable information to help troubleshoot issues and maintain optimal performance of your systems.
The Azure Stack Hub provides a convenient way for administrators to collect diagnostic logs on demand rather than waiting for them to be generated. As a key concept for those preparing for the AZ-600 Configuring and Operating a Hybrid Cloud with Microsoft Azure Stack Hub exam, understanding these steps not only helps in real-world scenarios but also inches you closer to passing your certification exam.
Collect Diagnostic Logs via the Administrator Portal
Here is a step-by-step guide on how to collect diagnostic logs using the Azure Stack Hub administrator portal.
- Log into the Azure Stack Hub administrator portal
- Navigate to the Region management tile on the dashboard.
- Click Region Management.
- Select a scale unit.
- On the scale unit page, click on the Infrastructure roles tab. A list of all registered infrastructure roles appears.
- From this list, choose the infrastructure role that you require diagnostic logs for and click on it.
- Click on the Diagnostic settings tab.
- In this tab, select Collect and Download.
- Once the logs are collected, a download link will appear on the same page, which you can click to download the diagnostic logs.
The above-given steps work for Nagios and Collectd, which are the two primary monitoring tools installed by default on Azure Stack Hub.
Remember, the logs collected via this method are in a .zip format. They are divided into directories for each role in the scale unit and consist of a variety of different kinds of information such as event logs, performance counters, crash dump files, configuration details, and more.

To determine when to use diagnostic logs, administrators should consider several scenarios:
- Troubleshooting: When Azure Stack Hub isn’t performing as expected, diagnostic logs provide needed details for troubleshooting.
- Error Detection: Diagnostic logs help administrators find and intercept issues before they result in system failure.
- System Monitoring: Regular monitoring of logs enables identification of patterns that could indicate potential problems.
In summary, collecting diagnostic logs on demand by using the administrator portal is a crucial task for administrators working with Azure Stack Hub. It’s an important concept covered in the AZ-600 Configuring and Operating a Hybrid Cloud with Microsoft Azure Stack Hub exam. As you prepare for this exam, make sure you understand how to collect logs, know when to use them, and appreciate their value in troubleshooting and maintaining the Azure Stack Hub system.
