Changelog

[0.125.0] - 2025-05-05

This Splunk OpenTelemetry Collector for Kubernetes release adopts the Splunk OpenTelemetry Collector v0.125.0.

💡 Enhancements 💡

  • agent: Keep the kubelet CPU usage metrics disabled by default for Splunk Observability users (#1822) k8s.node.cpu.usage, k8s.pod.cpu.usage and container.cpu.usage metrics are enabled by default in the kubeletstats receiver upstream, but we disable them for Splunk Observability users because they are not included in the default metrics set. If enabled, they will be charged as custom metrics. For now, container_cpu_utilization should still be used. Later, it will be replaced with one of the CPU metrics from the kubelet receiver once they are fully stabilized (e.g., container.cpu.usage or container.cpu.time).

  • operator: Bump nodejs to v3.1.2 in helm-charts/splunk-otel-collector/values.yaml (#1800)

[0.124.0] - 2025-04-24

[0.122.1] - 2025-04-10

This Splunk OpenTelemetry Collector for Kubernetes release adopts the Splunk OpenTelemetry Collector v0.122.0.

🛑 Breaking changes 🛑

  • logs: Disable migrateCheckpoint by default and introduce a new option migrateLogsCheckpoints to enable it if needed. (#1757)
  • agent: Remove smartagent/signalfx-forwarder from the agent default config. (#1759)

🚩 Deprecations 🚩

  • chart: Installing certmanager as part of the splunk-otel-collector helm chart is deprecated and will be removed in a future release. (#1763)

💡 Enhancements 💡

  • agent: Allow featureGates.useControlPlaneMetricsHistogramData to work with any distribution of k8s cluster. (#1760) Users can enable agent.controlPlaneMetrics for k8s components which run on worker nodes such as kubedns (gke), coredns (aks, eks) and kube-proxy (eks) with the feature gate featureGates.useControlPlaneMetricsHistogramData set to true. To disable collection of metrics from specific control plane components, set the corresponding component to false in the agent.controlPlaneMetrics configuration. For example: agent: controlPlaneMetrics: coredns: enabled: false proxy: enabled: false

  • all: Don't hardcode the command in the pod specs (#1758)

  • all: Add useMemoryLimitPercentage feature gate (#1761)

🧰 Bug fixes 🧰

  • clusterReceiver: Removes k8sattributes processor from Splunk Observability events pipeline which is enabled by the chart config infrastructureMonitoringEventsEnabled. (#1746)

[0.122.0] - 2025-03-31

This Splunk OpenTelemetry Collector for Kubernetes release adopts the Splunk OpenTelemetry Collector v0.122.0.

🧰 Bug fixes 🧰

  • agent/gateway: Ensure entity events are sent via gateway if enabled. (#1732)
  • clusterReceiver: Removes warning from chart when the clusterReceiver.eventsEnabled flag is set to true. (#1725) The clusterReceiver.eventsEnabled option which used k8s_events receiver is not being deprecated. This change removes the warning that was previously displayed when this flag was set to true.

[0.121.0] - 2025-03-18

This Splunk OpenTelemetry Collector for Kubernetes release adopts the Splunk OpenTelemetry Collector v0.121.0.

🧰 Bug fixes 🧰

  • other: Fixed updating metrics' sourcetype with annotations (#1375)

[0.120.1] - 2025-03-07

💡 Enhancements 💡

  • clusterReceiver: For the option, clusterReceiver.eventsEnabled, the logs pipeline for k8s_events now adds attributes of the type k8s.<objectkind>.name and k8s.<objectkind>.uid. (#1691) For example, if the log k8s event is about object type StatefulSet, the exported log to Splunk will have these 2 additional attributes: 
      k8s.statefulset.name: value(k8s.object.name)
  k8s.statefulset.uid: value(k8s.object.uid)
    The existing attributes k8s.object.kind, k8s.object.name and k8s.object.uid are still present. In addition to these, if the event is for kind Pod, and the k8s.object.fieldPath has a specific container spec, the log will have an additional attribute k8s.container.name with the value of the container name.

🧰 Bug fixes 🧰

  • agent: Do not setup the entities pipeline if Splunk Observability isn't enabled. (#1699)
  • agent: a fix for a scenario where some logs might be missed due to the pod log file being rolled over during high load, set featureGates.fixMissedLogsDuringLogRotation to true to enable the fix (#1690)
  • all: Restore values of service.name resource attribute for internal metrics changed in 0.120.0 (#1692) The value of service.name resource attribute was changed to otelcol due to a library upgrade in the Prometheus receiver. This change restores the values that were set before the based on the collector mode: otel-agent, otel-collector or otel-k8s-cluster-receiver.

[0.120.0] - 2025-03-03

This Splunk OpenTelemetry Collector for Kubernetes release adopts the Splunk OpenTelemetry Collector v0.120.0.

🛑 Breaking changes 🛑

  • operator: Migrate the operator to use Helm generated TLS certificates instead of cert-manager by default (#1648)
    • Previously, certificates were generated by cert-manager by default; now they are generated by Helm templates unless configured otherwise.
    • This change simplifies the setup for new users while still supporting those who prefer using cert-manager or other solutions. For more details, see the related documentation.
    • If you use .Values.operator.enabled=true and .Values.certmanager.enabled=true, please review the upgrade guidelines.

  • Add an option to skip RBAC resources creation (#231)
  • Enable container metadata. This gives all collected logs new attributes: container.image.name and container.image.tag. Also the native OTel logs collection gets container.id attribute that allows container level correlation in Splunk Observability Cloud closing a feature parity gap with fluentd (#238)
  • Add strict values.yaml schema validation (#227,#234,#239)

💡 Enhancements 💡

  • BREAKING CHANGE: Reorder resource detectors, moving the system detector to the end of the list. Applying this change in an EC2 or Azure environment may change the host.name dimension and the resource ID dimension on some MTSes, possibly causing detectors to fire.
  • BREAKING CHANGE: Reduce scope of host mounted volumes on linux systems (#232)
  • Change run_id log resource attribute to k8s.container.restart_count (#226)
  • Use only splunkPlatform.endpoint and splunkObservability.realm parameters to identify which destination is enabled, remove default value for splunkObservability.realm (#230,#233)
  • Upgrade splunk-otel-collector image to 0.37.1 (#237,#249)
  • Simplify configuration for switching to native OTel logs collection (#246)
