                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))
