scheduled.task
Scheduler stops. Site stays up.
A deploy clobbers your cron entry. The app responds 200. No one fires the scheduler. Your nightly emails stop.

Laravel cron
is lying
to you.
Crontinel watches Laravel scheduled tasks, queue workers, Horizon supervisors, backups, and agent runs, so you hear about the failure before your users do.

The gap Your uptime monitor says green.
Your uptime monitor says green.
Your queue disagrees.
A URL responding 200 doesn't mean your cron ran. It doesn't mean your workers are draining. It doesn't mean your invoices queue isn't 6,000 deep, or that your agent isn't looping on a broken tool call. Generic monitors can't tell you any of that.
agent.loop
The agent loops. The bill climbs.
A model retry storm or a tool-call loop runs for 40 minutes. The endpoint returns 200 for every request. You find out from billing.
api.status 200 ok agent.run.874 42m · 318 tool calls
worker.crash
Worker crashes. Queue is dead.
A worker process died. Your queue manager shows "running" because one worker is still up. Your billing queue is dead. No errors. No alerts. Just silence.

Everything uptime tools miss Paranoid monitoring,
Paranoid monitoring,
without the instrumentation.
One SDK hooks into your scheduler, queue driver and agent runner. It watches job runs, queue depth, worker state, model latency and agent tool calls, end to end. No endpoint pings. No per-task wrapping. No missed instrumentation.
Workers & supervisors
See the worker, not just the URL.
Per-worker status, paused detection, queue sparklines, failed job rate. Horizon, Sidekiq, Celery, BullMQ, RQ, Temporal. The moment one blinks, you know.
Heartbeat
60-second detection.
Every scheduled task registers a run attempt, exit code, and duration. Missed runs trip an alert before the next cron tick.
pulse 60s
No per-task instrumentation.
Hooks into your framework's events, not your code.
Works offline. MIT.
OSS first. Local dashboard, CLI, no SaaS needed.
Alerts
Route once, quiet forever.
One alert fans out to the channels your team actually watches - per-service routing, quiet hours, auto-resolve.
Slack PagerDuty Webhook Email
CI/CD
crontinel:check in your deploy hook.
One command verifies scheduler, supervisors and queues after each deploy. Zero-downtime monitoring that fails loud.
$ crontinel check ✓ scheduler last run 00:00:12 ago ✓ workers.default 2 supervisors · running ✓ queue.invoices 127 pending · 2m oldest ✓ agents.support 12 runs · p95 8.2s ✗ queue.emails backpressure · 6,413 pending
Agents & models
Monitor the agent like any other worker.
Track runs, tool calls, token spend, model latency and loop detection. Ask via MCP, so your own agent can answer "are any queues or agents backing up?" with real data.
› are any queues backing up?
Yes · emails is at 6,413 and rising. Oldest job 12m 04s. invoices is healthy.

Two commands.
One source of truth.
01 · INSTALL
One SDK, your stack
Drop the SDK in. No scheduler wrapping. No per-job decorators. No changes to existing jobs.

Listen instead of watch
We read scheduler events, worker state, queue internals and agent traces. When something drifts, you hear from us, not a user.

The inside of your queue.
Every scheduled task with its last run, duration and exit code. Every worker with its state. Every queue with depth, oldest job, and failure rate. Every agent run with its tool calls and token spend.

If you're comparing tools or looking for a specific Laravel failure mode, these are the strongest pages on the site.
Laravel cron vs queue monitoring
See what cron monitoring covers, what queue monitoring covers, and why you need both for Laravel production apps.
Laravel Horizon monitoring
Track paused supervisors, queue depth, and failing workers before the backlog becomes customer visible.
Webhook monitoring for Laravel and API teams
Catch delivery failures, retry storms, and stalled callback queues before customers notice.
Cron heartbeat monitoring for Laravel schedulers
Catch the moment schedule:run stops arriving, runs late, or silently skips a job.
Incident alert system for Laravel failures
Route the right failures to Slack, PagerDuty, or webhooks without drowning the team in noise.
Open source and self hosted status pages
Publish a simple public incident page for cron, queue, and webhook problems you control.
