The core system.

The core app that handles everything.

inspector/status: Rewrite/Simplify status information to make more sense. Split config and status.
inspector: Track duration and output of every result
Log all pertinent information (check results, results and their output, status changes etc) to a useful database. - Database options: SQLite, MongoDB, MySQL - Check values must be parseable
valueChange - Trigger results when a monitored value changes from last time
inspector.getOption: Generate error when parameters are missing

For every hos two states are kept:

current: The latest data.
previousStatus: When the ok status for the hostchanges, current is copied to previousStatus.

Each state has the following values:

counter: Is incremented with every execution of a check that set to changeReachable.
ok: Boolean value determining whether the host is reachable. Used to decide whether checks for this host should be executed.

For every check three states are kept:

current: The latest data.
previous: Before current is updated with the latest check results, it is copied to previous.
previousStatus: When the value for ok changes, current is copied to previousStatus.

Each state has the following values:

counter: Number of checks with the current ok value. Is reset when ok changes.
since: Date on which ok last changed.
ok: Boolean value determining whether the check was successful or not. Set to null on launch or when the check can't be executed due to the host being unreachable.
msg: Message from check execution.
output: Output from check execution.
values: Data values from check execution.
start: Start of the last check execution.
end: End of the last check execution.
duration: Duration of the last check execution.

Additionally each check has a meta object with the following values:

counter: Number of checks since app launch. Incremented with each check update.
running: Boolean value that is set to true while the check is being executed.
runningSince: Date when the check was started. Is null while the check is not running.
next: Date for which the next check execution is scheduled.

Each on event has the following status values:

counter: Number of times this event was executed.
running: Boolean value that is set to true while the event is being executed.
start: Start of the last event execution.
end: End of the last event execution.
duration: Duration of the last event execution.
error: Error (if any) of the last event execution.
output: Output (if any) of the last event execution.
