+description: Check and analyze tracer logs
+---
+
+Check and analyze Datadog .NET tracer logs for debugging.
+
+Log locations:
+- **Windows**: `%ProgramData%\Datadog .NET Tracer\logs\`
+- **Linux**: `/var/log/datadog/dotnet/`
+- **Application logs**: Look for logs in the application directory
+
+Log files:
+- **dotnet-tracer-managed-{ProcessName}-{PID}.log** - Managed tracer logs
+- **dotnet-tracer-native-{ProcessName}-{PID}.log** - Native loader logs
+- **dotnet-profiler-{ProcessName}-{PID}.log** - Native profiler logs
+
+Log levels:
+- ERROR - Errors that prevent functionality
+- WARN - Potential issues or degraded functionality
+- INFO - Normal operation information
+- DEBUG - Detailed debugging information
+
+Common log patterns to check:
+1. **Initialization**: "Datadog.Trace.ClrProfiler.Managed.Loader" messages
+2. **Configuration**: "Configuration" or "Settings" messages
+3. **Instrumentation**: "Instrumentation" or "CallTarget" messages
+4. **Errors**: "Error" or "Exception" messages
+5. **Performance**: Timing or "elapsed" messages
+
+When analyzing logs:
+1. Check for initialization errors first
+2. Verify configuration is loaded correctly
+3. Look for integration-specific messages
+4. Identify any errors or warnings
+5. Check for performance issues (slow initialization, etc.)
+
+Suggest solutions based on common patterns:
+- Missing dependencies
+- Configuration issues
+- Version mismatches
+- Permission problems
