# Bull Queue Exporter
**Prometheus exporter for Bull metrics.**
___
## UI
## Setup
#### Prometheus
**An existing prometheus server is required to use this project**
To learn more about how to setup promethues and grafana see: https://eksworkshop.com/monitoring/
#### Grafana
The dashboard pictured above is [available to download from grafana](https://grafana.com/grafana/dashboards/10128).
It will work aslong as EXPORTER_STAT_PREFIX is not changed.
## Queue Discovery
Queues are discovered at start up by running `KEYS bull:*:id`
this can also be triggered manually from the `/discover_queues` endpoint
`curl -XPOST localhost:9538/discover_queues`
## Metrics
| Metric | type | description |
|------------------------------|---------|-------------|
| bull_queue_completed | counter | Total number of completed jobs |
| bull_queue_complete_duration | summary | Processing time for completed jobs |
| bull_queue_active | counter | Total number of active jobs (currently being processed) |
| bull_queue_delayed | counter | Total number of jobs that will run in the future |
| bull_queue_failed | counter | Total number of failed jobs |
| bull_queue_waiting | counter | Total number of jobs waiting to be processed |
