deduct duplicate ip address
and link down
and router bug
instead of SNMPC
can you advice for new and proper tools ?
I can tell you what I use for the various networks that I manage. Typically I use LibreNMS, which is an auto-discovering PHP/MySQL-based network monitoring system that is very powerful. It is able to capture data from your devices and present it in a very comprehensive and understandable way. It’s generally easy to set up and it supports Syslog, SNMP, as well as NetFlow among others.
Take a look at LibreNMS and see if it fulfills your needs.
I hope this has been helpful!
