[Gabriel Martino]

Hi guys, i need to a certain element change its icons acordingly to its triggers values, see the explample:

~>80% usage : green
80%~90% usage : yellow

When you put a new element on the map and edit that element, you can choose the type. Select trigger there. Then you can select different images to be displayed when the trigger is OK en when it is in PROBLEM state.

This will only enable red/green, but no yellow possiblilty.

hmm i understood that, but what i want is to change the icons based on the state, i would like to create another new states( thera are already: default, problem, maintenance, disabled) to make the icon change accordingly to those new stats i would like to create

the images i made it myself and imported them into Zabbix
