Hello Ridhwan

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!
