      Remove modules and restart mango. Just take caution as to which modules it is you want to remove.

      Do not follow where the path may lead; go instead where there is no path.

          Mark the module for deletion and restart Mango.
          As MattFox said: "Just take caution as to which modules it is you want to remove."

              Hi Ralf and Matt,
              From modules option i marked my Log4j Data source to delete and clicked on restart mango button.
              After that i am not able to access mango UI it seems like application stopped and not started.
              Thanks

                Log4j is the logging system used by Datasources, it's not a datasource itself.

                Usually the modules show their dependencies. If not, go to store.infiniteautomation.com and look at download modules. They tell you what they need to work.

                Edit: Sorry I misread the note. Looks like something has not agreed. Check inside /opt/mango/logs/ma.log and see what the error is that's causing your mango instance not to load.

                    Hi shubhamthe log4J data source is not required to run mango. Those warnings are just websockets that have closed. This should not prevent you from logging in. What happens when you go to url: http://172.30.66.119:8080/ui/login ?
