You can view your Cron job executions directly from your project’s Services > Apps or Services > Workers pages. This visualization helps you quickly understand how scheduled jobs are performing and spot unusual patterns without manually checking logs. Each execution is represented visually, letting you monitor performance trends and failures at a glance. This makes it easier to:
  • Verify that scheduled jobs are running on time.
  • Identify failed or unusually long-running jobs.
  • Drill into logs only when something looks wrong.

​
How to view Cron job executions

  1. Open your project in the Console.
  2. Select your chosen Environment.
  3. Navigate to:
    • Services —> Apps & Services —> Apps —> app
    • Services —> Apps & Services —> Apps —> Workers (for background jobs).
  4. Click the Crons tab to view your scheduled jobs.
Each Cron job displays a visual history of its executions over time.

​
Understanding the visualization

Each execution appears as a vertical bar in the visualization: This combination of color and height helps in spotting outliers, for example:
  • A sudden tall red bar indicates a failed job that took longer than usual.
  • Consistently tall green bars suggest a job that may need optimization.
Each vertical bar corresponds to a single execution. Hover over any bar to view basic details such as:
  • Execution date and time
  • Duration
  • Status (success/failure)
Click a bar to open the detailed execution log, where you can inspect errors or performance information.

​
Troubleshooting and best practices

  • Monitor for patterns: Look for recurring red (failed) bars or progressively longer runtimes.
  • Drill into logs: Clicking a bar takes you directly to logs for that specific execution.
  • Correlate with metrics: Combine this view with application metrics to identify performance bottlenecks.
  • Adjust Cron timing: If jobs overlap or run too frequently, adjust their schedule in your crons configuration.

Investigate consistently high durations

If you notice that your Cron job runtimes are consistently increasing, this may indicate:
  • Growing data volumes,
  • Inefficient queries
  • Resource limits being reached.
Use profiling tools like Blackfire to identify and resolve performance issues.
