Knowing when something is wrong.
WHAT TO MONITOR
That the site responds That the checkout works That orders are arriving That order emails send That scheduled actions are processing
THE ORDER VOLUME SIGNAL
A sudden drop in orders is the clearest sign something broke.
If you normally receive orders daily and today there are none, check the checkout.
SCHEDULED ACTIONS
WooCommerce Status, Scheduled Actions.
A growing pending queue means cron is not running.
Orders may not progress correctly.
GATEWAY RECONCILIATION
Compare gateway transactions against shop orders weekly.
Discrepancies indicate a webhook problem.
UPTIME MONITORING
Use something that checks content, not just a response.
A site returning a database error still returns a response.
WHAT TO CHECK DAILY
New orders Anything stuck
WHAT TO CHECK WEEKLY
Gateway against orders Pending orders Stock accuracy
