At the current moment it is impossible to execute an operation based on two triggers with AND condition, as only one trigger can be processed by action. Action with condition like "Trigger1 and Trigger2" will never be executed.
This feature request is a request to change this limitation in a way, so that multiple triggers could be processed by an action and the according action could be executed.
Issue was discussed earlier in
ZBX-9660, and as a solution it was decided to add a sanity check on the frontend side to forbid storing of incorrect expressions (as per ZBX-9888). But maybe it is possible to review this issue and a find a better solution, which will not limit, but expand the possibilities of action by widening conditions and unloading the complexity of triggers.
