Tutorial / Cram Notes
It enables administrators to analyze and resolve problems with the hybrid cloud infrastructure. The Azure Stack Hub administrator portal provides a straightforward way for administrators to gather these logs on demand. Here’s a step-by-step guide on how to use the administrator portal to collect diagnostic logs.
Step 1: Access the Administrator Portal
To begin the log collection process, log in to the Azure Stack Hub administrator portal using your credentials. The portal can be accessed by navigating to the Azure Stack Hub administrative endpoint URL, typically formatted as https://adminportal.local.azurestack.external.
Step 2: Navigate to the Support + Troubleshooting Blade
Once you have logged in to the portal, look at the left-hand navigation pane for the “Support + Troubleshooting” section. Click on “Support + Troubleshooting” to access the tools and options available for diagnosing and addressing issues.
Step 3: Start the Diagnostic Log Collection
Inside the Support + Troubleshooting blade, you will find an option for “Resource health” or “Diagnostic logs”. Click on “Diagnostic logs” to begin the process of log collection.
Step 4: Configure Log Collection Parameters
Upon initiating the log collection process, you will be prompted to configure various parameters for the operation. This typically includes:
- Time Range: Specify the time period for which logs should be collected. It is important to align this with the period during which the issue has been observed.
- Log Type: Select the types of logs to collect. Options may include infrastructure logs, virtual machine logs, and more.
- Containers: For more granular log collection, you can choose specific containers from which logs should be extracted.
Make sure to select the appropriate parameters that correlate with the issue you are troubleshooting.
Step 5: Start the Log Collection Process
Once you have set the parameters, start the log collection process by clicking the “Start collection” button. The Azure Stack Hub will begin the process of gathering the logs from the specified sources.
Step 6: Monitor Log Collection Status
After triggering the log collection, stay on the page to monitor the status. The portal will display the progress of the collection process, including any successful or failed operations.
Step 7: Download Collected Logs
Upon completion, the portal will provide an option to download the collected logs. These logs are typically packaged in a .zip file format for convenience. Click on the “Download” button to retrieve the logs, ensuring you have the necessary permissions and disk space to store the file locally.
Step 8: Analyze the Logs
Downloaded logs can then be analyzed using tools like Microsoft’s Log Analyzer or integrated into other troubleshooting utilities. Ensure to handle the logs securely as they may contain sensitive information pertaining to the Azure Stack Hub environment.
Examples of Log Analysis:
- Infrastructure Logs: Provide detailed information regarding the Azure Stack Hub’s underlying infrastructure components, such as storage and networking.
- VM Logs: Offer insights into the operation and performance of virtual machines running in the Azure Stack Hub environment.
Best Practices for Log Collection:
- Schedule Regular Collections: For proactive monitoring, set regular intervals for log collection even if there are no immediate issues.
- Minimize Performance Impact: Collect logs during off-peak hours to minimize the impact on system performance.
- Secure Log Handling: Keep in mind the security implications when handling logs, as they may contain sensitive data.
In conclusion, collecting diagnostic logs through the Azure Stack Hub administrator portal is vital for maintaining a healthy hybrid cloud environment. By following these structured steps, administrators can systematically gather the necessary information to identify and resolve issues rapidly, ensuring minimal disruption to services.
