If we were to update the metrics -every second, the resulting graph would contain odd jitter. -### Troubleshooting - -To troubleshoot issues with the `riakkv` module, run the `python.d.plugin` with the debug option enabled. The -output will give you the output of the data collection job or error messages on why the collector isn't working. - -First, navigate to your plugins directory, usually they are located under `/usr/libexec/netdata/plugins.d/`. If that's -not the case on your system, open `netdata.conf` and look for the setting `plugins directory`. Once you're in the -plugin's directory, switch to the `netdata` user. - -```bash -cd /usr/libexec/netdata/plugins.d/ -sudo su -s /bin/bash netdata -``` - -Now you can manually run the `riakkv` module in debug mode: - -```bash -./python.d.plugin riakkv debug trace -``` - +integrations/riakkv.md
