Elasticsearch and Elastic APM Integration

Logging and Observability Standards

• Logging Standard: All logging must be implemented using Serilog with structured logging.
• Centralized Destination: All logs must be centralized in Elasticsearch, using Elastic APM authentication and Data Streams configuration.
• Enriched Information: Logs must be enriched with context properties such as app-name and app-type.
• Bootstrapping: Serilog initialization must be COMPLETELY OMITTED IN Program.cs and performed through an Extension Method from the Infrastructure layer.

Security and Data Privacy

• Sensitive Information: PII (Personally Identifiable Information), credentials, and tokens must NEVER be logged.
• Sanitize sensitive data before logging.
• Use log filters to exclude sensitive endpoints or data.

Serilog Configuration Extension Method

Create an extension method in Infrastructure/Extensions/ExtensionLogging.cs:
