Using Horizon exporters

We can export key metrics from Horizon to Prometheus. To enable this feature, uncomment this line in the app/Providers/PrometheusServiceProvider.php file.

$this->registerHorizonCollectors();

This will register the following collectors:

• horizon_master_supervisors: exports the number of master supervisors.
• horizon_current_processes: exports the number of processes currently running per queue
• horizon_current_workload: exports the number of jobs currently waiting per queue.
• horizon_failed_jobs_per_hour jobs: exports the number of failed jobs in the past hour
• horizon_status: exports if the Horizon is running, paused, or inactive
• horizon_jobs_per_minute: exports the number of jobs processed in the last minute
• horizon_recent_jobs: exports the number of recent jobs
