juju deploy alertmanager-k8s --channel dev/edgeAlertmanager handles alerts sent by client applications.
Alertmanager K8s is a Juju charm that deploys and manages Prometheus Alertmanager on Kubernetes. It is a core component of the Canonical Observability Stack (COS): https://documentation.ubuntu.com/observability
Alertmanager receives alerts from sources such as Prometheus and Loki, and takes care of deduplicating, grouping, and routing them to the appropriate receiver integrations — including email, PagerDuty, and others. It also supports silencing and inhibition of alerts.
Key features:
- Native high-availability clustering by simply scaling the application with Juju.
- Seamless integration with Prometheus, Loki, Grafana, Karma, Traefik, and other charms in the COS ecosystem through Juju relations.
- Built-in Grafana dashboards and Prometheus alert rules for self-monitoring.
- TLS support via the certificates relation.
- Distributed tracing support via integration with Tempo.
- Configurable Kubernetes resource limits for CPU and memory.
