telemetry

Fixed

• Explicitly pass own providers when registering instrumentations (the global providers may be influenced by, for example, Dynatrace OneAgent)

Added

• Support for tracing native db statements (i.e., cds.run('SELECT * FROM DUMMY'))
• Support for SAP Cloud Logging credentials via user-provided service
• Support for adding @opentelemetry/instrumentation-runtime-node
  • npm add @opentelemetry/instrumentation-runtime-node
  • to cds.requires.telemetry.instrumentations, add:

    "instrumentation-runtime-node": {
      "class": "RuntimeNodeInstrumentation",
      "module": "@opentelemetry/instrumentation-runtime-node"
    }
    

Changed

• Instrumentations are registered after tracing and metrics are set up
• telemetry-to-dynatrace: Regardless of whether Dynatrace OneAgent is present or not, if dependency @opentelemetry/exporter-trace-otlp-proto is present, @cap-js/telemetry will export the traces via OpenTelemetry.

Fixed

• Tracing of db statements without active span

Fixed

• Only startup plugin if invoked for runtime (e.g., via cli cds serve)

Fixed

• Detect build job started via @sap/cds-dk/bin/cds.js

Fixed

• Avoid credentials validation during cds build

Added

• Support for local modules (e.g., exporters) via [...].module = '<path relative to cds.root>'
• Disable pool metrics via cds.env.requires.telemetry.metrics._db_pool = false (beta)

Fixed

• Get credentials from cds.env
• Validate existence of credentials only for configured kind
• HTTP attributes only for root spans (reduces trace payload size)

Added

• Support for own, high resolution timestamps
  • Enable via cds.env.requires.telemetry.tracing.hrtime = true
  • Enabled by default in development profile

Added

• Register span processor also if tracer provider is initialized by a different module
• Support for so-called Pull Metric Exporter (e.g., @opentelemetry/exporter-prometheus)
• Tenant-dependent DB attributes

Changed

• By default, all system.* metrics collected by @opentelemetry/host-metrics are ignored
  • Disable change via environment variable HOST_METRICS_RETAIN_SYSTEM=true
• Metric exporter's property temporalityPreference always gets defaulted to DELTA
  • Was previously only done for kind telemetry-to-dynatrace
  • Set custom value via cds.env.requires.telemetry.metrics.exporter.config.temporalityPreference

Fixed

• Identification of first-level spans in built-in ConsoleSpanExporter

Added

• Register span processor also if tracer provider is initialized by a different module

Changed

• By default, all system.* metrics collected by @opentelemetry/host-metrics are ignored
  • Disable change via environment variable HOST_METRICS_RETAIN_SYSTEM=true

Added

• Re-use TracerProvider and MeterProvider that were initialized by a different module (OpenTelemetry only allows one-time initialization)

Fixed

• NonRecordingSpans are handled correctly

Added

• Support for exporting traces to Dynatrace via OpenTelemetry exporter (instead of Dynatrace OneAgent)
• Support for Dynatrace credentials via user-provided service
• @opentelemetry/host-metrics is automatically fired up, if it is in the project's dependencies

Added

• Predefined kind for SAP Cloud Logging (telemetry-to-cloud-logging)
• Built-in ConsoleMetricExporter prints DB pool and other metrics separately
