Laravel Queue Status Monitor

Once installed this will add itself to the schedule and dispatch a job
every minute on the default queue which updates a cached value.

The /queue-status-monitor endpoint shows the status of the monitor and
will return either 200 OK or 400 if queues have not run within the
expected threshold (5 minutes by default. This endpoint can be
monitored by Pingdom.

If you are using multiple queues, or if you wish to customise thresholds
you can add a monitor array to config/queue.php. Examples are:

Monitor a single queue

    "monitor" => "myqueue"

Monitor multiple queues

    "monitor" => [
        "myqueue",
        "myotherqueue"
    ]

Monitor a queue with a custom threshold

    "monitor" => [
        ["name" => myqueue","threshold" => 600]
    ]

Threshold values are specified in seconds and represent the point
where the monitor will report that the queue is failing if the
job has not run within that period.

Delay

As well as reporting the last run time, the /queue-status-monitor
endpoint also reports the delay. This is the time between the job
being dispatched and handled. This does not impact the overall status
and will not trigger failures. It is purely for reference.

Failed Jobs

By default, if you have a failed_jobs table, then any failures will
be treated as errors and generate a 400 status code. You can disable
this by adding the following to config/queue.php.

"do_not_monitor_failed_jobs" => true

Auth

If you want to protect your endpoint, add:

"status_password" => "YOURPASSWORD"

To the queue config. The default username is 'queues', but you can customise
this as well by setting:

"status_user" => "USERNAME"
