- When using `--prom` with a non-openshift clsuter, it will be necessary to pass the prometheus URL.
- `--metrics` will enable displaying prometheus captured metrics to stdout. By default they will be written to a csv file.
- `--iperf` will enable the iperf3 load driver for any stream test (TCP_STREAM, UDP_STREAM). iperf3 doesn't have a RR or CRR test-type.
- `--uperf` will enable the uperf load driver for any stream test (TCP_STREAM, UDP_STREAM). uperf doesn't have CRR test-type.
> *Note: With OpenShift, we attempt to discover the OpenShift route. If that route is not reachable, it might be required to `port-forward` the service and pass that via the `--prom` option.*
### Config file
#### Config File v2
The v2 config file will be executed in the order the tests are presented in the config file.
```yml
tests :
- TCPStream: # Place-holder of a test name
