# Ruby APM Troubleshooting

## Errors on Unit Tests

If you are getting errors when running unit tests you can disable the profiler w/ the `instrument` toggle.

Add `instrument` toggle to `config/stackify_apm`

```
instrument: false
```

Alternatively, create an environment variable `STACKIFY_INSTRUMENT` with a value of `false`.

## No APM Data

- Verify [Supported Technologies](/docs/supported)
- Verify that no other profiler is installed in project.
