Catalog position
Prometheus Alertmanager is a direct sub-tool of Prometheus, but it remains an independently deployable technology with its own process, configuration, API, release lifecycle, and high-availability behavior. Prometheus evaluates alerting rules and sends firing alerts to Alertmanager; Alertmanager then groups, deduplicates, routes, silences, inhibits, and delivers notifications [1].

Capability boundary
The catalog assigns three bounded capability families: alert management, notification routing and integrations, and incident-response control through silences and inhibition. Alertmanager does not scrape or store Prometheus metrics, evaluate PromQL alerting rules, or provide on-call schedules. Its shared reference cost is a small self-hosted compute and operator allowance, not a price published by the project. Its breadth score uses the canonical repository's public project activity as a mixed-confidence proxy [2].
Research stance
Treat this page as a maintainable evidence record, not an endorsement or direct ranking. Challenge the stance when Alertmanager's scope, lifecycle, deployment model, or first-party evidence changes.

Known limits
Unresolved unknowns
- Reference operating cost is a transparent small self-hosted allowance rather than a project price; deployment-specific receiver limits and availability require verification.
