Customers won't enter payment details on a site with certificate warnings. We monitor SSL health and alert you 30, 14, and 7 days before expiration. We also catch chain issues and misconfigurations that cause intermittent HTTPS failures on some browsers. [ Explore SSL monitoring ](https://ohdear.app/features/continuous-certificate-monitoring) ## Background job monitoring Inventory sync, order processing, email queues E-commerce runs on background jobs. Inventory syncs, order confirmations, shipping updates, abandoned cart emails. When these stop running, problems compound quickly. We monitor scheduled tasks and alert you when they stop running or take too long. No more silent failures.

We crawl your store daily and flag dead links before they cost you customers. Especially valuable after catalog updates, CMS changes, or platform migrations.

SSL issues go to your developer. Broken links go to your content manager. Use Slack, PagerDuty, email, or webhooks to match your workflow. When something breaks at 3am during a sale, the right person gets paged. [ View all notification channels ](https://ohdear.app/features/notifications) ## Status pages for customers Communicate during incidents When your store has issues, customers want to know what's happening. A status page reduces support tickets and shows you're on top of it. Our status pages run on separate infrastructure, so they stay up even when your store doesn't.

Oh Dear checks your store every minute from multiple global locations.
