Flapping Service - CHECK_NRPE: Error - Could not complete SS

[xzer]

The XI nrpe daemon is listenning on default port 5666. I am monitoring two host behind load balancer. Both are running on listening on 5666. The Load Balancer Port forwarding is set to forward ports comming on 15666 to HOST A(local NRPE 5666) and 5666 to HOST B(local NRPE Port 5666).

To get this running I have created custom command for HOST A, which is pointing to the 15666 Port command_line $USER1$/check_nrpe -H $HOSTADDRESS$ -p 15666 -t 30 -c $ARG1$ $ARG2$. For HOST B default is used.

This solutions is working, but the Problem is that I am getting Flapping Service on the HOST A all the day. The Error is CHECK_NRPE: Error - Could not complete SSL handshake and then it´s recovered. HOST B is running without any problem.

Normally, the sockets differs. Any Idea how to eliminate the flapping services? Can I deactivate SSL Hand Shake, by not choosing SSL?

Thanks.

I would check the system log to see if you are getting NRPE related errors (possibly xinetd)

Code: Select all

tail -f /var/log/messages
