## Troubleshooting
### Debug Mode
To troubleshoot issues with the `nginxplus` collector, run the `go.d.plugin` with the debug option enabled. The output
should give you clues as to why the collector isn't working.
- Navigate to the `plugins.d` directory, usually at `/usr/libexec/netdata/plugins.d/`. If that's not the case on
your system, open `netdata.conf` and look for the `plugins` setting under `[directories]`.
```bash
cd /usr/libexec/netdata/plugins.d/
```
- Switch to the `netdata` user.
```bash
sudo -u netdata -s
```
- Run the `go.d.plugin` to debug the collector:
```bash
./go.d.plugin -d -m nginxplus
```
