Disable Azure Monitor Application Insights to ensure accurate Site24x7 .NET APM agent monitoring
Why this is required
Site24x7 APM Insight and Application Insights rely on similar instrumentation mechanisms. Enabling both simultaneously can lead to:
- Missing or partial telemetry data.
- Inaccurate transaction traces.
- Increased performance overhead.
Therefore, disabling Application Insights ensures accurate and reliable monitoring.
Steps to disable Application Insights
- Log in to the Microsoft Azure Portal.
- Navigate to App Services, and choose the application where the Site24x7 .NET agent is installed.
- Navigate to Monitoring > Application Insights.
- From the left toolbar, click Application Insights. Click Disable, then select Turn Off, and in the pop-up window, click Yes to confirm.
Post-configuration steps
After disabling Application Insights:
- In the left toolbar, navigate to Extensions in your App Service.
- Ensure the APM Insight .NET Agent Extension is installed.
- Restart the app service for changes to take effect.
Best practices
- Use only one profiler-based monitoring tool at a time.
- Always restart the app service after configuration changes.
- Verify agent installation before troubleshooting data issues.
FAQ
1. Can I use both Site24x7 APM Insight and Application Insights together?
No, it is not recommended. Since both rely on similar instrumentation methods, running them simultaneously can interfere with each other’s data collection.
2. Is this applicable to all Azure hosting environments?
This applies specifically to applications hosted on Azure App Service where both Site24x7 APM Insight and Application Insights are enabled.
3. Can I re-enable Application Insights later?
