      As a user, I would like more information when I see "Unable to connect to CDAP..."

      I would like to see a relevant message surfaced in the "Unable to connect" box if:

      • a service or multiple services are down
      • CDAP master is not running
      • CDAP router is not running

      I'd like to be able to directly open the relevant logs (in a new tab).

      If CDAP is starting/stopping/restarting, I want a different message than "Unable to connect." I want an indication that CDAP is starting/stopping/restarting. In this case, I do not want to be presented with the options to directly view logs or restart.

      If I have exhausted the troubleshooting options above, I would like to see an option that will point me to contact my server administrator.

      As a user, I would like the admin page to help me better diagnose system issues.

      I would like the information about services to be displayed more intuitively and be able to access the logs more easily (see administration page mock).

      As a user, when I open the logs from the UI, I would like a message to be displayed if no logs are available so I don't see a blank screen.

      Logs that display as empty (no logs info displayed) should display the message "No logs available"
