Currently, it is not possible to rename alarms, once they have been created. When editing an alarm in the "Monitoring / Manage Alarms" view, it would be good to have the possibility to rename the alarm.
This feature has come as a part of the version 8.4 release. Sing up to our newsletter to be notified of upcoming releases.
