Network monitoring and its topology, what to choose?

Question

Computer networks

Just now I got a network, a bunch of incomprehensible static routes, a bunch of Wealans, clients in backbone links and the like, and a couple of enterprises with their lokhalkas also walk through the network.
During the year of managing this barn, I could not understand the old topology, as I was engaged in new segments, while new subscribers and pieces of the network grew in the old sections.
It is also difficult to figure it out due to the fact that the network was "administered" by 3-4 more people before me, and each contributed his own, it was brought to the point that no one could make out anything, there were no docks, but it was necessary to redo it.
The subject is actually this: I'm looking for a softinka that can collect devices via SNMP and LLDP (MNDP). looked at many solutions, zhabiks threw back because he does not know how to use some of the equipment, which is also a zoo (tiki, ubiki, d-links).
I myself am not a guru in customization, and it’s even difficult for a schoolboy, I only studied networks more or less, so I’m looking for a tool that more or less knows how to do this out of the box.

Answer 1

The decision was found, but rather and rather not trivial. Let me introduce you to the winner in the "decision of the century" nomination - NOC Project , you can also look at its description here and here . Although there is little exhaustive information, the dock is raw, and the bugtracker did not really answer any of my questions, I found everything I was looking for in this thing. There are a lot of tools, a lot, but you need to configure. In general, thanks to everyone for the advice.

Answer 2

I understand that this is not an answer to your question ... but there is little to help you here. The topology is too complicated
. I was in your place about 3 years ago, hitting one Internet provider.
I raked it with my hands, automating everything possible by using scripts + SNMP / SSH
I started simply by creating an actual interconnetion scheme. And then from simple to complex. I took 2 switches, opened the configs of both and looked (the configs of EVERYTHING should be immediately merged to tftp, this is the very first step here). What I understood - marked in the file and in desc. The rest was skipped ... it took six months to figure out the 3rd with colleagues.

Answer 3

There are no free ones, or finish them yourself for each manufacturer and firmware. If there is such a desire, zabiks or nocproject will help you. Of the paid ones, I recommend snmpc for monitoring.
And in general you did not describe the network. What is it - a broadband access provider, corporate offices, a mobile operator? In any domestic network (not a carrier network), there are no more than two hundred routers, excluding switches, and in yours, I suspect, no more than 50-80 at all (you didn’t mention mpls, and in general such a question would not arise in a large network). To paint such a topology is business for two weeks.

Answer 4

Support Valentine. Zabbix can do everything, you just need to finish it with your hands a little. Moreover, there are a lot of guides on it, it won’t be a particular problem to do what you want, though it won’t draw the network structure for you (maybe you can force it to somehow draw the topology, but I doubt it). If you need to monitor exclusively network hardware, then noc project is better, but this is real hardcore, but if you do it, it will be a very cool thing that will greatly simplify your life.
