 ### Metrics
 Metrics may be collected from the execution of each job.
 - [**Monitor**](https://pkg.go.dev/github.com/go-co-op/gocron/v2#Monitor):
+- [**MonitorStatus**](https://pkg.go.dev/github.com/go-co-op/gocron/v2#MonitorStatus) (includes status and error (if any) of the Job)
 A monitor can be used to collect metrics for each job from a scheduler.
   - Implementations: [go-co-op monitors](https://github.com/go-co-op?q=-monitor&type=all&language=&sort=)
