Karma

Karma gives responders a dashboard for browsing alerts supplied by Prometheus Alertmanager. It can combine alerts from several Alertmanager instances, reduce duplicate presentation and help users manage silences during investigation. It is useful when teams need a clearer shared view across monitoring sources. Karma displays and organizes those alerts; it does not evaluate the original monitoring rules or repair a broken notification path upstream.

Current guidance

The archived stable/karma chart identifies prymitive/karma, an alert dashboard for Prometheus Alertmanager. Current upstream documentation describes aggregation and deduplication across Alertmanager instances, preserving grouping and attaching source-cluster information. Keep Karma’s release and chart separate from the Alertmanager versions it connects to.

Configure every intended Alertmanager endpoint and verify the upstream’s minimum compatible version. In a highly available setup, deduplication should not hide a missing or misconfigured source. Check labels and grouping against the operational workflow so an operator can tell which cluster emitted an alert and where a silence will apply.

Treat UI access as an operational permission boundary because users may manage silences through the connected service. Protect upstream credentials and restrict dashboard access appropriately. Test an Alertmanager outage, duplicate alerts, a new silence and its expiry before relying on the dashboard during an incident. Karma cannot repair broken alert rules or notification routing upstream. The source review establishes the component’s role and migration checks, while the archived community chart’s image and Kubernetes manifests still require independent validation.
