About this tool.
Harvify Cron Monitor shows you exactly what your site’s scheduler is doing — and tells you when it stops. Unlike basic cron viewers, it records an execution history (duration, memory, success/error) so you can see what actually ran, not just what is scheduled.
Free features:
- List all WP-Cron events — hook, next run, recurrence, arguments, callbacks
- Full event management — run now, pause/resume, delete, with a safety guard on WordPress core events
- Add events — schedule an existing hook by name, or an HTTP request
- Execution history with timestamps — every run, its duration, memory, and status
- Overdue, missed, and broken-cron detection (including DISABLE_WP_CRON warnings)
- Action Scheduler queue visibility (precise timing for AS jobs)
- CSV export of history
- Dashboard widget — cron health at a glance
Pro features. These are not part of this plugin and are not included in this download. They are provided by a separate plugin distributed by Harvify:
- Alerts on missed, failed and long-running events — Email, Slack, Discord, and Telegram
- Auto-retry for failed events (bounded attempts with backoff)
- Per-hook performance metrics — average/max duration and memory, added by the separate Pro plugin (not included in this download)
- Email digests (daily or weekly) summarizing cron activity
- Multisite network view — cron health across every site
A note on timing accuracy
Action Scheduler events are measured precisely (we hook its before/after execution events). WordPress core has no native per-event start/finish hook, so WP-Cron timings are best-effort : we bracket each due hook’s callback on the cron request and record a fatal/timeout via the shutdown handler. WP-Cron rows are labelled “approx.” in the history so you always know which numbers are exact.
Security
This plugin does not evaluate code. It schedules hooks that already exist on your site, and can optionally perform an HTTP request on a schedule. There is no code editor and no author-supplied code is ever stored or executed.
