If the sensor stops capturing for some reason you may see "No Data" showing up in the GUI. You might get an alert that capture has stopped.
If you run "scotus stop" and then "scotus start" you may see the following message:
/bin/systemctl start solera-captured
A dependency job for solera-captured.service failed. See 'journalctl -xe' for details.
scotus: command '/bin/systemctl start solera-captured' failed with exit value '1'
root: scotus: command '/bin/systemctl start solera-captured' failed with exit value '1'
Here are some things to check to understand why capture has stopped.
