Important

If upgrading from a version older than 0.116.0, please review the upgrade guidelines for details about potential breaking changes.

💡 Enhancements 💡

splunk-otel-collector-0.116.0

This Splunk OpenTelemetry Collector for Kubernetes release adopts the Splunk OpenTelemetry Collector v0.116.0.

🛑 Breaking changes 🛑

• operator: Move operator CRD installation to the crds/ folder via a subchart to resolve Helm install ordering issues (#1561,#1619)
  • Users enabling the operator (.Values.operator.enabled=true) must now set operatorcrds.install=true in Helm values or manually manage CRD installation.
  • Previously, CRDs were installed using templates (operator.crds.create=true), which could cause race conditions and installation failures.
  • CRD installation is now handled via Helm's native crds/ directory for better stability, using a localized subchart.
  • If you use operator.enabled=true you may have to follow some migration steps, please see the Upgrade guidelines.

💡 Enhancements 💡

• collector: Document the possible use of a FIPS-140 compliant image (#1582)
• clusterReceiver: Configure k8s attributes processor for cluster receiver to ingest events into index defined in namespace annotation (#1481)
• agent: Make it so the default tolerations used to deploy the agent collector account for k8s distribution (#1562)
  OpenShift infra nodes and AKS system nodes will now be monitored by the agent by default
• operator: Bump dotnet to v1.8.0 in helm-charts/splunk-otel-collector/values.yaml (#1538)

• agent, clusterReceiver, gateway: Update config for scraping internal metrics to use new config interface and loopback address. (#1573)
  This also drops redundant attributes reported with the internal metrics: net.host.name and server.address

🧰 Bug fixes 🧰

• agent: Scrape FS metrics from one host disk mounted to the root to avoid scraping errors since the collector likely doesn't have access to other mounts. (#1569)
• gateway: add signalfx exporter to the gateway traces pipeline to enable APM correlation (#1607)

splunk-otel-collector-0.113.0

This Splunk OpenTelemetry Collector for Kubernetes release adopts the Splunk OpenTelemetry Collector v0.113.0.

🧰 Bug fixes 🧰

• agent: Fixes hostmetrics receiver to use the correct mount path of the host's filesystem from inside the container (#1547)
• agent: Exclude scraping filesystem metrics from mounts that are not accessible from inside the container to avoid scraping errors. (#1550)

splunk-otel-collector-0.112.1

⚠️ Known issue ⚠️

This release of the Helm chart is not recommended to use due to the following issue:

• agent: Host metrics reported by this version are incorrect. The collector container assumes itself as a host instead of fetching data from the underlying node.

splunk-otel-collector-0.112.0

This Splunk OpenTelemetry Collector for Kubernetes release adopts the Splunk OpenTelemetry Collector v0.112.0.

⚠️ Known issues ⚠️

This release of the Helm chart contained the following issues, both resolved in the next patch release:

• agent: The hostmetrics receiver failed to scrape the some filesystem targets (#1533)
• operator: Instrumentation opentelemetry.io/v1alpha1 could sometimes attempt to be installed prematurely (#1544)

🛑 Breaking changes 🛑

• agent, gateway, chart: update default traces exporter to otlphttp (#1518)
  If you use the sapm exporter with custom settings, you have two options:
  • Migrate your sapm settings to the new otlphttp exporter.
  • Retain SAPM settings by moving them to your agent.config or gateway.config overrides to ensure they remain effective.

💡 Enhancements 💡

• operator: Bump operator to 0.71.2 in helm-charts/splunk-otel-collector/Chart.yaml (#1511)
• operator: Bump java to v2.9.0 in helm-charts/splunk-otel-collector/values.yaml (#1509)
