No. It would minimally affect your network utilization.

No. You should not need to change anything on your servers. The routers need to allow ping traffic (protocol UDP:ICMP) which is enabled by default.

icinga [-h] [-v] [-s] [-d] <main_config_file> DESCRIPTION
icinga is a daemon program that monitors the status of various network accessible systems, devices, and more. For more information, please consult the online documentation available at http://www.icinga.org, or on your Icinga server's web page. OPTIONS
main_config_file The main configuration file. On debian systems this defaults to /etc/icinga/icinga.cfg -h A helpful usage message -v Reads all data in the configuration files and performs a basic verification/sanity check. Always make sure you verify your config data before (re)starting Icinga. -s Shows projected/recommended check scheduling information based on the current data in the configuration files. -d Starts Icinga in daemon mode (instead of as a foreground process).
