Introducing Karma: A Prometheus Alert Dashboard Tool

Karma is a Prometheus alert dashboard tool designed to aggregate alerts from multiple Alertmanager instances and present them on a single visual board, improving convenience and management of alert messages.

Because Alertmanager’s native UI lacks dashboard capabilities, Karma was created to fill this gap by providing a consolidated view of alerts across data centers and clusters.

The product can be deployed as a Docker container with a single command. It requires Alertmanager version ≥ 0.22.0 and uses port 8080. Example command:

$ docker run --rm --name karma -d -p 8080:8080 -e ALERTMANAGER_URI=https://
ghcr.io/prymitive/karma:latest

After deployment, the dashboard is accessible at the following URL (replace with your host):

http://
:8080

Feature 1 – Alert Visualization : Karma aggregates alerts from multiple Alertmanager instances, automatically summarizes similar alerts, and offers filtering by status, labels, source, etc., enabling quick identification and handling of specific alerts.

Feature 2 – Tag‑Based Multi‑Grid : Users can group alerts by tags or other attributes, creating separate grids for each tag value and an additional grid for alerts without the selected tag, facilitating clear organization across environments and severity levels.

Feature 3 – Silence Management : Karma allows management of silences configured in Alertmanager, including creating new silences and applying ACL rules to control their creation and editing.

Overall, Karma provides a rich set of practical features that make it a strong complement to the Prometheus monitoring stack, offering an effective solution for alert board needs.
