I'm trying to create an alert that is triggered when usage for any mount point on any server is in excess of 80%.
When creating a threshold alert under Watcher, I'm looking at getting the average of system.filesystem.used.pct and group this by both terms and system.filesystem.mount_point (which does not appear to be present in the drop-down menus at all). However, it does not appear that I can enter this type of contruct in the GUI.
Does this sort of query need to be configured via JSON directly or am I missing a trick here? If it must be in JSON, could anybody offer any examples?
