Dear technical team, I want to divide the value of two channels. let me explain more about my problem. i want to divide the send traffic to receive and then multiply it to 100 : (send/receive)*100 , i created a sensor factory and in Channel Definition part i wrote : ((2348,0)/(2348,1))*100 but i got a bad request error : The validation of at least one of the new objects faild because of the following : . At least one channel must be defined. i don't know what to do to resolve this problem. ive to mention that the sensor is port channel interface of a cisco router and it has traffic value in gigabit /s . i would really appreciate it if you could help me, thanks in advance.
