Consider also open-source FlowViewer for netflow capture and analysis. A lot of very useful netflow based analytical tools in an easy UI. Sits on top of a robust set of Carnegie-Mellon's high-capacity SiLK netflow tools. https://sourceforge.net/projects/flowviewer/ Joe ----- Original Message ----- From: "William Herrin" <bill () herrin us> To: "Colton Conor" <colton.conor () gmail com> Cc: "NANOG" <nanog () nanog org> Sent: Wednesday, August 15, 2018 3:25:48 PM Subject: Re: What NMS do you use and why?

We are looking for a new network monitoring system. Since there are so many operators on this list, I would like to know which NMS do you use and why? Is there one that you really like, and others that you hate?
I still use a tool I wrote in perl nearly 20 years ago called "MrPing." MrPing handles multi-dependency graphs. Consider: A is reachable via either B or C. If A and B are down but C is up, A being down is a separate failure from B being down. I need to know about both. If B and C are both down, A is unreachable. I don't want to receive alerts about A because they'll distract me from the root cause of the problem: that both B and C are down. The NMS should record that A is unreachable but it should also tell me that A being unreachable is a dependent failure that I can ignore until I fix the failures it depends on. The NMSes I've paid attention to either don't support dependencies well at all or support only simple hierarchical dependencies. Resilient, professional networks simply aren't built that way.
