What kind of an impact, if any, on the server if I monitored 3 different TCP ports every 5 seconds on 4 different nodes? We have 2 clusters of 2 servers and if they dont hear from each other every 10 seconds they will both fail over and try to become master causing issues. 1 server in each cluster is off site. We have no other way to check if there was a failure between the 2 until users complain.
Thanks!
