The Team
We are part of the Observability team, alongside Tracing and Service Mesh.
The Work
feat: Compressed Prometheus remote-write alert rules, with tests, so large rule sets fit within relation limits: mimir, opentelemetry-collector-k8s, opentelemetry-collector, mimir (2.17), opentelemetry-collector-k8s (0.130), opentelemetry-collector (0.130)- feat: Enabled out-of-order sample ingestion so late-arriving metrics are no longer dropped: prometheus-k8s, mimir, prometheus-k8s (backport), mimir (2.17)
- feat: Added a charm config option to disable anonymous reporting: mimir, tempo, mimir (backport)
- feat: Brought the OpenTelemetry Collector and OTLP endpoints into COS and COS Lite, plus Canonical K8s support: observability-stack, observability-stack, observability-stack
- feat: Added a /ready endpoint to the Loki nginx config for cleaner readiness checks: loki
- feat: Alert Knob now validates rules after applying customizations: cos-lib
fix: Fixed WAL compression configuration, including a breaking change to the config surface: prometheus-k8s, prometheus-k8s (3.11)- fix: Fixed scrape jobs behind ingress and self-monitoring with ingress plus TLS: prometheus-k8s, prometheus-k8s (3.11)
- fix: Made dashboard forwarding robust: duplicates deduplicated by content and unreadable relations skipped instead of erroring: opentelemetry-collector-k8s, opentelemetry-collector-k8s (0.130), opentelemetry-collector-k8s (0.130)
- fix: Derived unit count from the peer relation instead of goal-state, avoiding unreliable scaling behaviour: opentelemetry-collector-k8s, opentelemetry-collector-k8s (0.130)
- fix: Fixed TLS handling, including correct treatment of key and certificate files: opentelemetry-collector-k8s, opentelemetry-collector-k8s
- fix: Migrated to the charmlibs certificate transfer library, resolving flapping certificate state: opentelemetry-collector-k8s
- fix: Fixed lintian errors in the OpenTelemetry packaging: opentelemetry-packaging
perf: Avoided unnecessary CA certificate refreshes on every event: opentelemetry-collector-k8s
refactor: Removed the legacy self-monitoring scrape job (breaking change): prometheus-k8s
test: Rewrote rules customization tests as BDD feature files: cos-lib, cos-lib
docs: Updated Traefik track documentation, microceph links, and out-of-order sample troubleshooting for Mimir: observability-stack, observability-stack, observability-stack, observability-stack
