• Fixed SPLUNK_REALM environment variable taking precedence over endpoint supplied programmatically. endpoint now correctly overrides the endpoint created via SPLUNK_REALM and when both are set logs a warning. #668
• Empty environment variables are now considered as not defined. #693
• New configuration option: SPLUNK_DEBUG_METRICS_ENABLED / metrics.debugMetricsEnabled. #700 When set, extra set of internal troubleshooting metrics are produced. This should only be enabled to assist debugging. Defaults to false. Currently debug metrics for the CPU and memory profiler are produced, each being a histogram:
  • splunk.profiler.cpu.start.duration
  • splunk.profiler.cpu.stop.duration
  • splunk.profiler.cpu.process.duration
  • splunk.profiler.heap.collect.duration
  • splunk.profiler.heap.process.duration

For a list of major changes and features in 2.0.0 see the notes for 2.0.0-rc1.

Additional changes in this release:

• Upgrade to OpenTelemetry JS 1.8.0 / 0.34.0. #612
• Remove @opentelemetry/instrumentation-aws-lambda from the bundled packages as there exists a separate lambda instrumentation and due to the package not being compatible with @opentelemetry/instrumentation@0.34.0. #612.
• @opentelemetry/api is now a peer dependency and the required version has been bumped to 1.3.0.
• OTEL_LOG_LEVEL now also sets up the logging pipeline, thus diagnostic logging can now be enabled just by enabling it
  via the environment variable. The supported log level values are none, verbose, debug, info, warn, error.
  The logging pipeline can additionally be enabled by setting logLevel configuration option. #605.
• process.command, process.command_line and process.runtime.description resource attributes have been removed from the automatic process detection. #613
• OTEL_TRACES_EXPORTER now only supports otlp, console or both (e.g. OTEL_TRACES_EXPORTER=otlp,console).
  #599
• Add support for OTEL_EXPORTER_OTLP_PROTOCOL, OTEL_EXPORTER_OTLP_TRACES_PROTOCOL, OTEL_EXPORTER_OTLP_METRICS_PROTOCOL. The supported values are grpc (the default) or http/protobuf. #599 #614
