This should probably be run as separate from cron_bridge.php if at all possible, unless you force this to be the very first thing that runs each time cron_bridge.php runs. Reason for this is because if it's not the first thing that runs, and something in the cron tasks queue fails before it gets to this, then health check might not run.

(Alternative option: #3316 )

I think putting it first makes sense, good suggestion. I wouldn't want to make any one configure 2 CRON processes.
