UNSOLVED How to Limit Data Sources options


  • How can we reduce the datasource types.
    We are referring this url:- http://172.30.66.119:8080/ui/administration/data-sources/


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

  • Thanks for the reply,

    Can you guide us how to remove the modules.


  • Select menu Administration/Modules

    0_1582890810865_69beda9f-e6b4-4562-a3dd-af4ad89b4cd2-image.png

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


  • Thanks Ralf!


  • 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
    Shubham Rajvanshi


  • 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 ?


  • Hi Creig,
    After that mango application become unreachable, login page also to coming.
    below is the error also present in log file.
