answering question based on b conn output

It seems that a simple b conn all show all output has really useful information. For example, I could answer important questions, like "Which client has the highest number of connections to a part...

Thank you, though I have already seen this and a couple other similar commands. There are quite a number of questions I have asked myself that could be answered by these types of commands - I just haven't generated all the commands myself yet.

 

 

For example, a while back we suddenly saw our baseline number of connections jump from 500k to 1.5M. It would have been nice to simply run a shell script that showed me the number of connections open by each client, and the number of connections open to each VIP. If I would have had the ability to quickly answer those questions, I could have diagnosed what was going on much more quickly (the DNS vulnerability patch sent out a while back changed how DNS responses worked, which had a dramatic impact on our connection table). Instead while I was able to figure it out, it took me a while.

 

 

My question isn't necessarily exactly what commands can I use to get that information - I can probably figure that out myself, but just haven't had a chance to do it yet. I just thought that it might be likely that someone else had already needed to answer many of the same questions, and already had a script for it.

 

 

I'm just lazy.
