Unreleased

Added

Add initContainer for log checkpoint migration from Fluentd to Otel agent (#253)
Add index routing for Splunk Enterprise/Cloud customers (#256)

Fixed

Fix metrics/logs disabling for Splunk Platform destination (#259)

[0.37.0] - 2021-10-26

Upgrade guidelines

Added

Add recommended Kubernetes labels (#217)
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)

Changed

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)

Fixed

Fix setting of SPLUNK_MEMORY_TOTAL_MIB env var in otelAgent daemonset (#240)
Enable OTLP HTTP ports (4318 and 55681) in otelAgent daemonset (#243)
