v1.2.0

Added

• Improved support for tracing messaging services and cds.spawn
• Support for adding custom spans to trace hierarchy via tracer.startActiveSpan()
• Trace attribute db.client.response.returned_rows for queries via cds.ql
• Option to pass custom config to span processor via cds.requires.telemetry.tracing.processor.config
• Support for loading instrumentation hooks via path relative to cds.root.
  • The respective module must export either a function or, for bundling purposes, an object with a function named after the respective hook.
  • Example based on @opentelemetry/instrumentation-http:

    "instrumentations": {
      "http": {
        "config": {
          "ignoreIncomingRequestHook": "./lib/MyIgnoreIncomingRequestHook.js"
        }
      }
    }

• Support for ignoring incoming requests that match a certain base path via cds.requires.telemetry.tracing.sampler.ignoreIncomingPaths = [] (beta)
• Experimental!: Trace HANA interaction via @cap-js/hana's promisification of the driver API for increased accuracy
  • Enable via config cds.requires.telemetry.tracing._hana_prom
  • Requires @cap-js/hana^1.7.0
• Experimental!: Intercept and export application logs (cf. cds.log()) via OpenTelemetry
  • Enable by adding section logging to cds.requires.telemetry as follows (using grpc as an example):

    "logging": {
      "exporter": {
        "module": "@opentelemetry/exporter-logs-otlp-grpc",
        "class": "OTLPLogExporter"
      }
    }

  • Requires additional dependencies @opentelemetry/api-logs, @opentelemetry/sdk-logs, and the configured exporter module (cds.requires.telemetry.logging.module)

Changed

• Default config ignoreIncomingPaths: ['/health'] moved from cds.requires.telemetry.instrumentations.http.config to cds.requires.telemetry.tracing.sampler

Fixed

• User-provided instances of SAP Cloud Logging should have a tag "cloud-logging" (not a name matching "cloud-logging")

Removed

• Internal cds._telemetry
