How to Read and Analyze Azure Entra ID Diagnostic Settings

Once you’ve configured Azure Entra ID diagnostic settings, it’s essential to know how to read and analyze the data they provide. Here are some tips to get you started:

Log Analytics

Log Analytics provides detailed insights into system performance, security, and user activity. To analyze Log Analytics data:

1. Navigate to Log Analytics: Click on the Log Analytics tab located in the left-hand menu.

2. Choose the Log Level: Select the log level you want to analyze, such as INFO, WARNING, or ERROR.

3. Filter and Search Logs: Use the filtering and search capabilities to narrow down the logs based on specific criteria, such as date, time, and event type.

 Filter: 
  EventID == 4624
    AND
  EventLevel == WARNING
    AND
  Timestamp >= ago(1h)

This filter searches for WARNING-level logs with EventID 4624 that occurred within the last hour.

Metrics

Metric data provides insights into system performance and usage patterns. To analyze metrics data:

1. Navigate to Metrics: Click on the Metrics tab located in the left-hand menu.

2. Choose the Metric: Select the metric you want to analyze, such as SignInFailed or AverageResponseTime.

3. Configure the Time Range: Set the time range for which you want to analyze the metric data.

Metric	Description	Units
SignInFailed	Number of failed sign-in attempts	Count
AverageResponseTime	Average response time for authentication requests	Milliseconds

Diagnostic Logs

Diagnostic logs provide detailed information about system events, errors, and warnings. To analyze diagnostic logs:

1. Navigate to Diagnostic Logs: Click on the Diagnostic Logs tab located in the left-hand menu.

2. Choose the Log Level: Select the log level you want to analyze, such as INFO, WARNING, or ERROR.

3. Filter and Search Logs: Use the filtering and search capabilities to narrow down the logs based on specific criteria, such as date, time, and event type.

 Filter: 
  EventID == 1500
    AND
  EventLevel == ERROR
    AND
  Timestamp >= ago(1h)

This filter searches for ERROR-level logs with EventID 1500 that occurred within the last hour.

Common Scenarios and Troubleshooting

In this section, we’ll explore common scenarios and troubleshooting techniques using Azure Entra ID diagnostic settings:

Scenario 1: Investigating Sign-in Issues

If users are experiencing sign-in issues, you can use Log Analytics to investigate the cause:

1. Search for Sign-in Related Logs: Use the filtering and search capabilities to search for logs related to sign-in attempts, such as EventID 4624.

2. Analyze Log Data: Analyze the log data to identify patterns, such as failed sign-in attempts, authentication errors, or unexpected latency.

3. Configure Additional Diagnostic Settings: Configure additional diagnostic settings, such as Metrics or Diagnostic Logs, to gather more detailed information.

Scenario 2: Optimizing System Performance

If you’re experiencing performance issues, you can use Metrics to identify bottlenecks and optimize system performance:

1. Monitor Performance Metrics: Monitor performance metrics, such as AverageResponseTime, to identify performance bottlenecks.

2. Analyze Metric Data: Analyze metric data to identify patterns, such as spikes in latency or throughput.

3. Optimize System Configuration: Optimize system configuration, such as scaling up or out, to improve performance.

Conclusion

Azure Entra ID diagnostic settings provide a powerful toolset for optimizing system performance, improving security, and troubleshooting issues. By following the best practices outlined in this article, you can unlock the full potential of Azure Entra ID diagnostic settings and take your identity and access management to the next level.
