There is a problem in choosing the right software and settings for monitoring the networks of the whole company with more than 500+ un addresses.
There is a server on OpenBSD that needs to monitor more than 500+ servers in real time and send a report to all servers with logs every day at the end of the working day, where it will be written from how many hours to how many IP addresses did not work.
If I'm not mistaken, then Nagios had such an opportunity, not when it was not necessary to tune it ..
