I have to monitor, if a tcp connection between 2 servers in 2 different network segments (separated by firewalls) is stabil or gets aborts after a couple of time. So the 2 server should have a permanent connection, which is monitored. Is it correct, that a Icinga master has a permanent connection to his satellites, which is checked continuously by the cluster (or cluster-zone) check? My first idea was, just to install a Icinga Satellite in the other network segment and use the cluster checks to see aborts.
Anyway, are you guys are monitoring sth. like this, too and has a best practice?
