signalfx/splunk-otel-collector v0.122.0

on GitHub

This Splunk OpenTelemetry Collector release includes changes from the opentelemetry-collector v0.122.1
and the opentelemetry-collector-contrib v0.122.0
releases where appropriate.

🛑 Breaking changes 🛑

• (Core) service: Batch processor telemetry is no longer emitted at "basic" verbosity level (#7890)
  According to the guidelines, basic-level telemetry should be reserved for core Collector APIs.
  Components such as the batch processor should emit telemetry starting from the "normal" level
  (which is also the default level). Migration: If your Collector telemetry was set to level:
  basic and you want to keep seeing batch processor-related metrics, consider switching to level:
  normal instead.
• (Contrib) deltatocumulative: removes legacy and clean up existing metrics (#38079)
• (Contrib) sqlserverreceiver: SQL Server receiver now requires a positive serial number for X509 certificates.
  See known issues in README of receiver/sqlserverreceiver for more information. (#38099)

🚀 New components 🚀

• (Splunk) Add opamp extension (#5999)

💡 Enhancements 💡

• (Splunk) Add a new discovery bundle for Istio metrics which includes proxy, gateway, and pilot/istiod (#5854)
  • This discovery receiver, named prometheus/istio, is disabled by default. Users can enable it by setting the discovery config splunk.discovery.receivers.prometheus/istio.enabled=true.
• (Splunk) Update splunk-otel-javaagent to v2.14.0 (#6000)
• (Splunk) Update jmx-metric-gatherer to v1.45.0 (#5995)
• (Splunk) Use direct connection for MongoDB discovery (#6042)
• (Core) service: Add service.AllowNoPipelines feature gate to allow starting
  the Collector without pipelines. This can be used to start with only extensions.(#12613)
• (Core) service: include component id/type in start error (#10426)
• (Core) confmap: Introduce a new feature flag to allow for merging lists instead of discarding the existing ones.
  You can enable this option via the command line by running following command:
  otelcol --config=main.yaml --config=extra_config.yaml --feature-gates=-confmap.enableMergeAppendOption
