Is there a list of the pro/s and con/s of NRPE vs. SNMP when using icinga?
I have no idea what's the best way to handle the returned data of plugins back to my icinga monitoring machine.
Usage of SSH as connection is no option for me.
I see no where that Icinga or Nagios use snmp to handle returned data of plugins. Icinga use nrpe and you don't need a ssh connection, nrpe bind a socket that listen on port 5666, so you have only to open tcp connection on that port.
