Hi Michele,

Thanks for your time and reply.

We here have a requirement to implement a CLI to get these stats.
And one of the options we thought to use was /proc files to get these stats.

Going through the mail chain of this patch (http://www.spinics.net/lists/linux-sctp/msg01813.html) , I came across this.
" socket option is preferable as /proc doesn't scale very well as number of associations grows."

Here I am just curious to know how much "is the number of associations" referred to?

Thanks & Regards,
Prasad

This is trivial as we've done so for RHEL 6.5 already.

It was preferred to do it via an API extension, similar to how
Solaris does it. And, I believe, the /proc interface for these kind of
things is discouraged.
