Thanks Its work like a charm

This plugin is great.
Anyway I have question after read the code. There is commented warning “do not override previous return value from overall health”, what’s the effect if I try to override the value? I want to override ambient temperature warning and critical values to lower value, since one day I found that the air conditioner in my server room didn’t work and the temperature hit about 30 C (some reference said ideally it should be about 20). Is it OK to ask question here?
thanks In advance
