This page provides instructions for troubleshooting Artdaq configuration tools and services running on pddaq-gen05-daq0.cern.ch. Two systemd services must be running for the web configuration editor to work mongod and node, which spawns twenty sub-processes. Both of them can be checked from either pduser or root accounts. Carefully review outputs, and look for complaints and error messages, which point to a problem.

systemctl status  webconfigeditor@cern_pddaq_v3_db.service
systemctl status  mongodbserver@cern_pddaq_v3_db.service

If the reported status is not active then login as root and issue a restart, or wait for 5 mins until systemd does it automatically.

systemctl restart webconfigeditor@cern_pddaq_v3_db.service
systemctl restart  mongodbserver@cern_pddaq_v3_db.service

Confirm that both services are enabled using the following commands

systemctl is-enabled webconfigeditor@cern_pddaq_v3_db.service
systemctl is-enabled  mongodbserver@cern_pddaq_v3_db.service

systemctl enabled webconfigeditor@cern_pddaq_v3_db.service
systemctl enabled  mongodbserver@cern_pddaq_v3_db.service.
