Background job monitoring — no silently stalled queue.

Relvato checks your WordPress Action Scheduler queue is actually draining — catching the stalled or stuck jobs that quietly stop order emails, subscription renewals and stock sync.

The quiet case: the Action Scheduler queue is short, fresh and draining.

This monitor reads data from inside WordPress, so it needs the free Relvato plugin.
What it checks
  • ✓The Action Scheduler queue is draining, not growing
  • ✓No jobs stuck ‘in-progress’ past their runtime
  • ✓The pending backlog is within a healthy bound
  • ✓Flags the stalled job groups
Why it matters

WooCommerce and half your plugins rely on background jobs. When the queue stalls — a fatal in a hook, a killed cron — everything that depends on it just stops, with no error you’d notice. Relvato watches the queue depth and age so you catch it in time.

One-click fix

On WordPress, a stalled or jammed Action Scheduler queue has a one-click fix in WordPress → Relvato: the plugin runs the queue once — only jobs that were already due, for a few seconds — which also releases jobs stuck mid-run and clears jobs whose plugin was removed. If WP-Cron is switched off on the site, the fix says so, because that's why the queue would stall again.

How it works
  • The plugin reads your Action Scheduler queue — pending, in-progress and failed counts and ages.
  • Flags a growing backlog or jobs stuck past their expected runtime — the signature of a broken cron.
  • Runs on a schedule and on change, so a stalled queue is caught before customers notice missing emails.
Questions, answered
What breaks when the queue stalls?

Order emails, subscription renewals, stock sync, and anything else scheduled — often silently.

Does it need the plugin?

Yes — reading the Action Scheduler queue state needs the WordPress plugin.

Can Relvato unstick the queue?

Yes, with the Relvato plugin: one click in WordPress → Relvato runs Action Scheduler's own queue runner once, for jobs that were already due. It also tells you when WP-Cron is switched off on the site — the usual reason a queue stalls in the first place.
