components

The following components exist:

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.

configuration

To get the system working, first install the database. After that, create an alarm mapping:

insert into mappings(name, description) values ('default', 'The default mapping');
insert into mapping_level values (1, 0, 0, 'okay', 'green');
insert into mapping_level values (1, 1, 1, 'okay', 'orange');
insert into mapping_level values (1, 2, 2, 'okay', 'red');
insert into mapping_level values (1, 3, 3, 'okay', 'gray');

Next is to create a notifier. This feature doesn't work 100% yet and needs some work and may look different later:

insert into notifier(name) values ('default');

After that create a check command:

insert into commands(name, command, message) values ('ping', 'ping -n -c 1 {{ .ip }}', 'Ping a target');

This command can contain variables that are set in the check. It will be executed by moncheck and the result stored.

After that, create a node which will get the checks attached:

insert into nodes(name, message) values ('localhost', 'My localhost is my castle');

With that prepared, create the first check:

insert into checks(node_id, command_id, notifier_id, message, options)
values (1, 1, 1, 'This is my localhost ping check!', '{"ip": "127.0.0.1"}');

Now start the daemons moncheck, monfront and monwork.

monwork will transform the configured check into an active check, while moncheck will run the actual checks. Through monfront one can view the current status.
