Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Integrating Cisco ASR with Splunk without Splunk Stream.
I would greatly appreciate insights and recommendations from those who have experience in this area. Additionally, I'm interested in hearing your opinions on the best tool for this task: nProbe or goflow? Your rationale behind your recommendation would be invaluable.
FastNetMon
- Versatile open source toolkit to detect volumetric DDoS attacks

A DDoS attack with unknown scr and dst port.
If you have a BGP peering with you ISP/upstream provider, ask them if they have a blackhole community you can broadcast to. Usually they are ASN:666. The only downside is you would only be able to advertise your IP address to that, essentially killing your internet (if that's your only IP) as long as the block is up. We usually set our filter to 15 minutes and most attackers give up after that. At this level, you probably would have your own ASN with a small range and could potentially use something like FastNetMon (https://fastnetmon.com) to automatically advertise and remove IPs from the community.

Processing netwflow data
Have you looked at fastnetmon ? It's freemium and It looks like the commercial version would work you, but I think the community edition is aslo worth a look. It's primary function is to detect DDOS attacks, but it can export data in ways that might be useful to you.

WAN Attacks is it just whack-a-mole?
To mitigate DoS attacks means you need information - preferably before the users start screaming. Running sampling on your edge router with something like Fastnetmon will give you alerting of a probable DDoS attack before it becomes a significant problem.
