0.10.0

What's Changed

• Replaced OTEL Collector Builder with committed source code by @gantrior in #580
• Upgrade OTEL Collector and 3rd party Docker images by @pstranak-sw in #579
  • Updated OTEL collector from 0.91.0 to 0.98.0. Included bugfixes from the upstream OTEL collector processors into the local ones.
  • Updated runtime to Go 1.22. The OTEL Collector dropped support for Go 1.20 (that version is out of support). Since Go 1.21 and 1.22 support the same relevant operating systems and platforms, we could just switch to 1.22.
• ⚠️ Droped support for several Windows versions that are out of support. The minimum requirement is now Windows 10 or Windows Server 2016. This is caused by the update of Go (and OTEL Collector).
• Removed Docker image attestations from the built images. Some security scanners could not process the images because of them.

Full Changelog: 0.9.2...0.10.0

swo-k8s-collector-3.3.0-alpha.5

Added

• Added option to configure nodeSelector and affinity for SWO Agent.

Changed

• Added environment variables CLUSTER_UID, CLUSTER_NAME and MANIFEST_VERSION to the SWO Agent StatefulSet. Future SWO Agent plugins may include them in their metrics.
• Upgraded collector image to 0.10.0 which brings following changes:
  • See Release notes for 0.10.0.
  • Bumped 3rd party dependencies and Docker images.
  • Upgraded OTEL Collector to v0.98.0.
  • ⚠️ Dropped support for several Windows versions that are out of support. The minimum requirement is now Windows 10 or Windows Server 2016. This is caused by the update of Go (and the OTEL Collector).

swo-k8s-collector-3.3.0-alpha.4

Changed

• Added validation schema for the provided Helm chart configuration.

swo-k8s-collector-3.3.0-alpha.3

Changed

• Container logs from AWS EKS Fargate clusters are now sent to SWO as-is. fluentbit.io/parser and fluentbit.io/exclude annotations are ignored. This both fixes an issue with "empty" JSON logs sent to SWO and aligns the behavior with non-Fargate container logs.
  This change is applied only to Pods that are started after the new k8s collector is deployed to the k8s cluster.

swo-k8s-collector-3.3.0-alpha.2

Fixed

• Fixed Journal log collection on EKS (and other environments where journal logs are stored in /var/log/journal)

swo-k8s-collector-3.3.0-alpha.1

Added

• Added an option to configure timeout for each attempt to send data to SWO.
  • The default value is 15s (previously it was 5s) to avoid unnecessary retries when the backend takes time to respond.

Changed

• Add validation of the OTEL endpoint provided in values.yaml. In case a deprecated endpoint is detected, report a warning during chart installation/update.

swo-k8s-collector-3.2.0

Added

• Added Linux ARM64 support
• Added Windows Server 2019 support
• Added option to deploy OpenCost collector
  • Can be enabled by setting openconst.enabled to true in values.yaml
• Added option to pull images from ACR by setting global.azure.images.<image_key> in values.yaml when running in AKS
• Added otel.api_token to allow setting API token for OTEL collector through values.yaml
• Added otel.metrics.autodiscovery.prometheusEndpoints.podMonitors configuration option. Define if you want to monitor applications that do not have Prometheus annotations.
• Started publishing custom Istio metrics, when available: k8s.istio_request_bytes.delta, k8s.istio_response_bytes.delta, k8s.istio_requests.rate, k8s.istio_tcp_sent_bytes.rate, k8s.istio_tcp_received_bytes.rate, k8s.istio_requests.delta, k8s.istio_tcp_sent_bytes.delta, k8s.istio_tcp_received_bytes.delta, k8s.istio_request_bytes.rate, k8s.istio_response_bytes.rate and k8s.istio_request_duration_milliseconds.rate

Changed

• Upgraded OTEL collector image to 0.9.2 which brings following changes
  • see Release notes for 0.8.11, 0.8.12, 0.8.13, 0.9.0, 0.9.1, 0.9.2
  • Switched from scratch base image to distroless
  • Bumped 3rd party dependencies and Docker images
  • OTEL upgraded to v0.91.0
• Adjusted node-collector memory limits for better performance
• Removed sha256 from image references to enable multiarch support
• Removed k8s.kube_daemonset_labels, k8s.kube_deployment_labels and k8s.kube_statefulset_labels metrics (they were redundant anyway)
  • There are no longer published by the updated kube-state-metrics
• Stopped sending histogram metrics to SWO
• Added PVC for SWO Agent, when enabled

Fixed

• Fixed autoupdate job
• Fixed usage of ebpfNetworkMonitoring.k8sCollector.relay.image.pullPolicy
• Fixed restarts of the collector when automatic discovery and scraping of prometheus endpoints (otel.metrics.autodiscovery.prometheusEndpoints.enabled) was disabled or enabled on a Fargate environment

swo-k8s-collector-3.2.0-alpha.17

Fixed how k8s.istio_request_duration_milliseconds.rate metric is calculated

swo-k8s-collector-3.2.0-alpha.15

Fixed

• Fixed restarts of the collector when automatic discovery and scraping of prometheus endpoints (otel.metrics.autodiscovery.prometheusEndpoints.enabled) was disabled

swo-k8s-collector-3.2.0-alpha.13

Changed

• Make sure discoverd histogram metrics are not sent to SWO
• Publish custom Istio metrics, when available: k8s.istio_request_bytes.rate, k8s.istio_response_bytes.rate and k8s.istio_request_duration_milliseconds.rate
