What should be the maximum limit of latency in elb AWS

I am using ELB CloudWatch. My configuration is :

Metric Name : Latency
Statistic : Average
Latency >=2 for 5 consecutive period(s)

I am getting notifications : Threshold Crossed: 4 datapoints were greater than or equal to the threshold (2.0)

I want to avoid these types of email. So what changes i need to do in alarm configuration. What should be the maximum value of latency ?

There is no "correct" value. Set it according to the behavior you expect from your application -- the latency metric is primarily measuring how responsive the back-end servers are, not the ELB itself. It measures how long your back-end systems are taking to begin their responses.

Latency

The time elapsed, in seconds, after the request leaves the load balancer until the headers of the response are received.
