## Exposed Metrics
| Metric name | Metric type | Description | Labels |
| ----------- | ----------- | ----------- | ------ |
|mpi\_operator\_jobs\_created\_total | Counter | Counts number of MPI jobs created | |
|mpi\_operator\_jobs\_successful\_total | Counter | Counts number of MPI jobs successful | |
|mpi\_operator\_jobs\_failed\_total | Counter | Counts number of MPI jobs failed| |
|mpi\_operator\_job\_info | Gauge | Information about MPIJob | `launcher`=&lt;launcher-pod-name&gt; <br> `namespace`=&lt;job-namespace&gt; |
### Join Metrics
With [kube-state-metrics](https://github.com/kubernetes/kube-state-metrics), one can join metrics by labels.
For example `kube_pod_info * on(pod,namespace) group_left label_replace(mpi_operator_job_infos, "pod", "$0", "launcher", ".*")`
