Github/gist list of modern telemetry/networking polling tools

[Drew Weaver <drew.weaver () thenap com>]

Hello,

If you guys are like me I find something that works and I just stick with it.

Now that we're getting to a place where we can re-tool some of our monitoring and telemetry for our network I am 
looking for information/recommendations on new tools.

Specifically I am looking a list of NMS, SNMP poller/grapher, sflow/netflow cap/dump tools that people are enjoying.

I know a lot of times people post lists of tools over on github or a gist so I am just wondering if anyone has any 
lists for this that they like?

Thanks,
-Drew
