Monitor and troubleshoot Azure solutions

You develop an ASP. Net Care application by integrating the Application Insights SDK into your solution.

The application sends telemetry at a very high rate over a short interval. You observe fewer events, traces, and metrics being recorded, along with increased telemetry-ingestion error rates. Telemetry data must synchronize client and server information to enable HTTP request and response correlation.

You need to reduce telemetry traffic, data costs, and storage costs while maintaining a statistically accurate analysis of application telemetry data.

What should you do?

Explanation

Fixed-rate sampling reduces telemetry volume before ingestion while retaining a representative fraction of the data for statistically valid analysis. A consistent sampling decision across the telemetry in a trace preserves correlated request, response, and related telemetry; Application Insights can account for the sampling rate when reporting counts. Source-level sampling also reduces ingestion and storage costs, unlike changing a workspace tier or applying a daily cap.
