2. What's the difference between WCF Diagnostics Tracing vs. Application Insights?

Part of the WCF Diagnostics Tracing troubleshooting and FAQ guide.

Both tools capture WCF service behavior, but they serve different purposes and have very different cost profiles. Use this cost comparison to choose the right tool for your scenario.

Feature Comparison

Feature WCF Diagnostics Tracing Application Insights
SOAP payload retention ✅ Unlimited (no size limits) ❌ 64 KB max
Retention period ✅ 7+ year retention ❌ 90 days default
Business self-service ✅ Log Views (no query language) ❌ KQL queries required
Retroactive Search Field extraction ✅ Yes ❌ No
Deployment ✅ On-premise or cloud ⚠️ Azure subscription required
APM telemetry ⚠️ Not primary purpose ✅ Distributed tracing, dependencies
Annual cost (15 GB/day) ✅ ~$5,400/year ❌ $30K+/year

When to Use Each

Use Application Insights for APM telemetry — request rates, distributed tracing, dependency tracking, and exception monitoring across modern cloud services.

Use Nodinite WCF Diagnostics Tracing for complete business transaction logging — full SOAP payloads, 7+ year retention, business self-service with Log Views, retroactive Search Field extraction, and 85% cost savings compared to cloud-based alternatives.
