TODO

• 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

Status data

Host

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.

Check

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.

on

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.
