                Zabbix: handle calculated item with zero division
              
          
    Problem

Want to create a calculated item with last("X") / last("Y").
When Y = 0, the result should be 0.
Answer

last("X") * (1 - count("Y",#1,0)) / (last("Y") + count("Y",#1,0))


## Github feature pull request
Github "feature pull" request or "idea pull" request

Sometimes, we solve problems or create features that have already been fully implemented in similar software. Why reinvent the wheel? Well, maybe there is a good reason, but we should at least know that we're doing that.

Example:
edX platform has forums, but the featureset leaves something to be desired. Other open-source projects have (or are) forums that already have these features. How should we model a feature request for edX platform to add these features?

Opportunities:
Point to a branch or a commit in another github project that implements the feature or idea you care about in that project.
