Opentelemetry Collector K8S

Vendor-agnostic way to receive, process and export telemetry data.

OpenTelemetry Collector K8s is a Juju charm that deploys and manages the OpenTelemetry Collector on Kubernetes, providing a vendor-agnostic telemetry pipeline for receiving, processing, and exporting metrics, logs, traces, and profiles. It is a component of the Canonical Observability Stack (COS): https://documentation.ubuntu.com/observability

The collector aggregates telemetry from related charms and forwards it to the appropriate backends such as Prometheus, Loki, and Tempo through Juju relations.

Key features:

• Vendor-agnostic telemetry collection covering metrics, logs, traces, and profiles in a single workload.
• Native OTLP ingestion (gRPC/HTTP) as the primary protocol, with additional support for Jaeger and Zipkin.
• Automatic scraping of Prometheus metrics endpoints from related charms.
• Forwarding of telemetry to COS backends — Prometheus (remote write), Mimir, Loki, and Tempo — through Juju relations.
• Built-in Grafana dashboards for self-monitoring.
• TLS support with configurable CA trust via the receive-ca-cert and receive-server-cert relations.
• Ingress support for cross-model telemetry collection through Traefik.
• Configurable processors, sampling rates, and scrape intervals.
• Grafana Cloud integration via the cloud-config relation.
• Persistent storage for telemetry data durability across container restarts.
• Configurable Kubernetes resource limits for CPU and memory.
