swo-k8s-collector-3.0.0

Changed

• Prometheus is no longer needed for kubernetes monitoring, therefore it is no longer deployed. By default, k8s collector does not scrape anything from Prometheus.
  • If there was a Prometheus deployed by the previous version (using setting `prometheus.enabled``), it will be automatically removed.
  • Setting otel.metrics.prometheus.url is still available, but is valid only in combination with otel.metrics.extra_scrape_metrics.
  • If otel.metrics.prometheus.url is empty, `otel.metrics.prometheus_check`` is ignored to not fail on missing Prometheus.
  • Note that otel.metrics.extra_scrape_metrics is deprecated option and will be removed in future versions.
• Decreased the default batch size for metrics, logs and events sent to OTEL endpoint to 512 to avoid too big messages
• Upgraded OTEL collector image to 0.8.8 (see Release notes)

Added

• Added network monitoring for Linux nodes which is based on eBPF, so it does not require service mesh to be deployed.
  • It is disabled by default, to enable it set ebpfNetworkMonitoring.enabled: true in values.yaml
  • It is based on opentelemetry-ebpf
  • See exported_metrics.md for list of metrics
