Currently you can't override the settings of a LLD trigger. This makes it laborious to change, for instance, the severity. That leads you to the following:

• You need a separate trigger
  • You can't easily clone the trigger
  • You can't leave the trigger description the same, as that'll cause a conflict

When you follow the hyperlink of an LLD trigger, you're brought to the trigger prototypes. If you're cloning a prototype, you'll only get another prototype, but not a trigger local to the host. Thus you have to copy all the details from the prototype and fill in hard-coded parts to create a usable trigger. That's somewhat confusing and boring.

It's not likely that every filesystem on a host is equally important, nor will they all use the same limits. Therefore it is essential to easily override these figures.
