Hi Aditya,
I hope you might tried to edit the alarm cause through tools->utilities->event configuration by searching alarm id or alarm type. Once the event is modified with either event message or event title or severity you need to update and save events from VNM model to get changes effective.
Expand spectro-server universe tab and select VNM Model and navigate to component detail->SpectroServer control and click on update event configuration so that the made changes will be updated for that specific spectro-server VNM Model.
Open Spectrum URL in browser and navigate to administrator tab, to to left side select update events and alarm files followed by clicking reload tab so the changed events get effective.
Regards,
Vishnu Prasad
