Few Platform Logs and Metrics Go Missing When Streaming Them From Diagnostic Setting to Event Hub: A Step-by-Step Guide
Introduction
In today’s cloud-based environment, logging is an essential process for monitoring and troubleshooting any application. Streaming logs and metrics from Diagnostic Setting to Event Hub can help streamline this process and provide valuable insights into application performance and behavior. However, it is not uncommon for some of these logs and metrics to go missing during the process. In this blog post, we will provide a step-by-step guide on how to troubleshoot this issue and ensure that all logs and metrics are streamed successfully.
What You Will Need
Before you begin troubleshooting, you will need the following items:
* An Azure subscription
* An Event Hub
* A Diagnostic Setting
Step 1: Create an Azure Subscription
The first step is to create an Azure subscription. This will give you access to all of the Azure services you need for streaming logs and metrics from Diagnostic Setting to Event Hub. You can create a subscription by signing up for a free trial or purchasing a subscription through the Azure portal.
Step 2: Create an Event Hub
The next step is to create an Event Hub. This will be the destination for the logs and metrics that you stream from your Diagnostic Setting. To create an Event Hub, log into the Azure portal and select the “Create a resource” option. This will open a new window where you can search for and select the “Event Hubs” resource. Then, you can follow the on-screen instructions to create your Event Hub.
Step 3: Create a Diagnostic Setting
Now that you have an Event Hub, you will need to create a Diagnostic Setting. This is the source of the logs and metrics that you will be streaming to your Event Hub. To create a Diagnostic Setting, log into the Azure portal and select the “Create a resource” option. This will open a new window where you can search for and select the “Diagnostic Settings” resource. Then, you can follow the on-screen instructions to create your Diagnostic Setting.
Step 4: Configure Your Diagnostic Setting
Once you have created your Diagnostic Setting, you will need to configure it. You can do this by selecting the “Configure” option for your Diagnostic Setting. This will open a new window where you can select the “Event Hubs” tab and configure the settings for your Event Hub. Make sure to select the correct Event Hub and configure the other settings as needed.
Step 5: Test Your Configuration
Once you have configured your Diagnostic Setting, you will need to test it to make sure that it is working properly. To do this, select the “Test” option for your Diagnostic Setting. This will send a test log to your Event Hub to make sure that it is working properly. If everything is working correctly, you should see the log in your Event Hub.
Step 6: Troubleshoot Missing Logs and Metrics
If you are still experiencing issues with missing logs and metrics, there are a few things you can do to troubleshoot the issue. The first thing you should do is check the Event Hub to make sure that the logs and metrics are being sent to it. If they are not, then you may need to check the configuration of your Diagnostic Setting to make sure that it is set up correctly. You may also want to check the log retention settings to make sure that the logs are not being deleted before they can be sent to the Event Hub.
Step 7: Monitor Logs and Metrics
The final step is to monitor your logs and metrics to make sure that they are being sent to your Event Hub. You can do this by setting up alerts in your Event Hub. This will allow you to be notified when logs or metrics are missing so that you can take action to fix the issue.
Conclusion
Streaming logs and metrics from Diagnostic Setting to Event Hub can be a great way to streamline the logging process and provide valuable insights into application performance and behavior. However, it is not uncommon for some of these logs and metrics to go missing during the process. In this blog post, we provided a step-by-step guide on how to troubleshoot this issue and ensure that all logs and metrics are streamed successfully.
