The record

Purpose: Cabot is a self-hosted watchdog for websites and infrastructure that alerts when services go down or metrics exceed thresholds.
Logical service monitoring: Cabot monitors logical services across one or many machines and combines related checks into service statuses.
Built-in checks: The homepage lists Graphite metrics, Jenkins jobs, and web endpoints as things Cabot can monitor.
Graphite thresholds: Graphite checks support equality and greater-than or less-than comparisons against a chosen metric threshold.
Severity levels: Services have Passing, Warning, Error, and Critical statuses, and telephone alerts are limited to Critical status when the listed service and duty-officer conditions are met.
Plugins: Plugins can add alerting and check functionality, but the documentation says listed plugins may not have been validated and should be tested at the user's own risk.
Deployment: The quickstart recommends Docker Compose and supports running Cabot behind Caddy or a separately configured reverse proxy.
API: Cabot documents a browsable API with HTTP Basic or session authentication and Django permission checks for write methods.
License and cost: The project describes Cabot as free and open source, and its repository identifies an MIT license.
Maintenance: The repository says Cabot is stable and used in production but is not actively maintained, and that maintainers are wanted.
Support and limitations: The services documentation says a formal alert acknowledgement and escalation procedure may suit larger organizations, and invites suggestions and pull requests.
Monitoring: It can monitor Graphite metrics, Jenkins jobs and web endpoints.
Service monitoring: Cabot groups checks into logical services, which can run across multiple machines.
Alert severity: Service statuses include Passing, Warning, Error and Critical, with alert frequency depending on status.
