I am going to implement a monitoring solution with icinga2 for my firm and I need to know how much bandwith is this going to use. The solution has to monitor about 10000 hosts with 10 per host and I am worried about the bandwith utilization. The traffic has to cross some firewalls and is important to not saturate the current bandwith available or increase it if it would be necessary.
Regarding to this, How much bandwith is used by a check command (an estimation will be fine)? I will use the following types of checks:
ping, cpu, ram, snmp, and some windows and linux services.
Many thanks for your help.
