Health Check Interval

By default, HAProxy Enterprise sends a health check every two seconds. Change this by adding the inter parameter to the server line. In the next example, health checks are sent once every four seconds:

backend be_myapp
   server srv1 10.0.0.1:80 check inter 4s
   server srv2 10.0.0.2:80 check inter 4s

Use any of the following time suffixes:

• us : microseconds

• ms : milliseconds

• s : seconds

• m : minutes

• h : hours

• d : days

Other parameters that affect the check interval are defined below:

The diagram below describes at which phase each of these settings applies.
