## Requirements

Monado comes with it's own metrics collection and is built by default. No action
is needed by the developer to build the Monado sides of things. You will need to
checkout the [metrics repo][] to get the tools to analyse the resulting output
from Monado.

## Running

Launch the service with the env variable `XRT_METRICS_FILE` set.

```bash
XRT_METRICS_FILE=/path/to/file.protobuf monado-service
```

After Monado has finished running run the tool in the [metrics repo][], follow
the instructions in the [README.md][] file inside of that repo, there are more
instructions there.
