Quality of Service checks on DHCP clients

I'm looking for a way to monitor network jitter and latency on home networks via Nagios XI. Since these are DHCP clients (end user home networks) that may change IPs in the future outside of our control, I am thinking that these need to be passive checks so that the clients talk to our server and not vice versa. My users frequently use VOIP systems so we want the ability to monitor their networks to detect whether they may be having issues so we can both provide more information to our providers and be better able to support our end users when they expererience network related issues.

Does anyone have experience with this or could guide me in the right direction? I found the check_traffic plugin that may do what i'm asking for but wanted to see if there were any alternatives or better ways to approach this: https://exchange.nagios.org/directory/P ... sh/details

Hey @HometownQuotes!

Welcome to the forum. :D

The ideal would probably be to set up dynamic DNS so that you could specify a host name instead of an IP address for your checks. It may require more time up front, but you wouldn't have to update the IP address on your XI server every time it changes.
DDNS

You could also add the IP to a specific file in /etc/hosts every time it changes. You may choose this option depending on the scale of your operation.

I hope that helps! Let me know if you have any more questions.
