Job Monitoring That Doesn't Lie (Cron Edition)

Cron jobs are some of the most important parts of a system. They run backups, sync data, send emails, clean queues, and generate reports. And yet, they are still one of the easiest things to get wrong.

Most cron failures are not dramatic. They are quiet, delayed, or invisible.

A dashboard might say “Last run: OK,” but the job actually ran 40 minutes late. Or worse, it never ran at all and no one noticed.

This is the core problem with traditional cron monitoring today.

Cron jobs are not servers

Traditional monitoring tools were built for web services. They check if something is up and responding. That model does not map well to scheduled jobs.

A cron job has intent. It is expected to run at a specific time, within a specific window, and produce a result. If it runs late, that already matters. If it does not run at all, that is a failure—even if nothing crashed.

Treating cron like uptime hides real problems.

“Last run: OK” is a lie

“Last run: OK” tells you almost nothing.

• Did it run on time?
• Was it late?
• Did it partially fail?
• Did it silently skip today?

Most tools cannot answer these clearly. They show green states that feel reassuring, but they do not reflect reality.

This is how teams end up discovering issues from customers, missing data, or broken reports—instead of alerts.

What honest job monitoring looks like

Honest cron monitoring starts with one simple idea: a job should explicitly say when it runs.

Instead of guessing based on schedules or log scraping, the job sends a heartbeat when it actually executes. Monitoring becomes about facts, not assumptions.

From there, the important states become obvious:

• On Schedule: ran within the expected window
• Late: ran, but outside the expected time
• Failed: explicitly reported failure
• Missing: no signal at all

Late is not the same as failed. Missing is not the same as healthy.

If your monitoring cannot make these distinctions, it will lie to you.

When a state becomes a problem

Knowing a job is Missing is useful. Knowing it has been Missing for three hours is urgent.

This is the difference between state and criticality. A job can be Late for five minutes (probably fine) or Late for two hours (definitely broken). Most tools treat these the same.

Pakyas separates state from urgency. A job enters critical state when:

• It has been Missing beyond a configured threshold
• Failures keep repeating past a tolerance limit
• It has been running far longer than expected
• The job itself signals something is wrong

Critical is not a replacement for Missing or Late. It is a signal layered on top: “This specific situation now requires human attention.”

This matters because not every failure is critical. A nightly report that fails once might recover on retry. That same report failing five nights in a row is a pattern. The first is a state. The second is critical.

Jobs can also explicitly signal critical themselves. A backup script that detects data corruption can tell Pakyas directly: this is critical. The job knows its own failure modes better than any external system.

Why we built Pakyas

We built Pakyas because existing tools still blur these lines.

Pakyas is a job monitoring system designed for cron jobs and background work, not server uptime.

They are often UI-heavy, difficult to automate, and noisy by default. Many are fine products, but they treat cron as a secondary concern instead of a first-class problem.

Pakyas is built specifically for scheduled jobs and background work:

• Execution-signal-based job monitoring by default
• Lateness and criticality as first-class states
• CLI-first and automation-friendly
• Alerts that distinguish urgency from noise
• Notifications through channels your team actually uses
• Designed to coexist with existing monitoring while you migrate

No agents. No lock-in. Just clear signals.

Pakyas routes alerts where they matter. Critical situations can interrupt through SMS. Routine state changes can go to Slack or email. You configure the escalation path once; Pakyas applies it consistently.

Monitoring should reduce stress, not add it

Good monitoring should be boring. It should fade into the background until something truly needs attention.

Green should mean safe. Alerts should mean action. And when something is truly critical, you should not have to dig through a dashboard to find out.

If you have ever trusted a cron job and later found out it had been broken for hours or days, you already know why this matters.

Job monitoring should not lie.
