Agrafa is open-source, self-hosted monitoring software for nodes and services. It reports CPU, memory, disk, and heartbeat status from connected nodes, and checks URLs or host-and-port targets over HTTP and TCP. Alert rules can notify users when a service is degraded, unhealthy, or crosses a threshold, with email notifications configured in Instance Settings. The node agent sends metrics and heartbeats outbound to the Agrafa server, so monitored machines need no inbound ports for that connection. Installation starts a dashboard and API on ports 8080 and 8081 by default. The dashboard, API, checks, and agents run on infrastructure controlled by the operator, with monitoring data staying inside that setup according to the site. Agrafa supports Linux, a web dashboard, and self-hosted Docker Compose deployment under the MIT license. It is aimed at small deployments, personal infrastructure, and side projects. Service history, latency tracking, incident tools, status pages, container monitoring, and historical insights remain planned.
Who it is for
Agrafa suits operators of small deployments, personal infrastructure, or side projects who want self-hosted node and service checks. It fits teams that prefer keeping monitoring components on infrastructure they control.
What is good
- Monitors CPU, memory, disk, and heartbeat status
