components

The following components exist:

moncheck

Moncheck is the daemon that runs the checks and generates notifications in the database. It is possible to run multiple instances of moncheck, as it uses PostgreSQL as a coordinator through the PostgreSQL internal locking mechanism.

Moncheck uses the table active_checks to detect which checks to run.

monfront

Monfront is a webfrontend to view the current state of all checks, configure hosts, groups, checks and view current notifications. It is possible to run multiple instances.

monwork

Monwork is a small server that does all the maintenance work in the background. It is responsible to cleanup the history and generate the configuration.

The configuration is generated into active_checks when an entry in nodes, command or checks was changed (detected through the updated column).
