Subject: K(ret)probe for TCP time to connect?
Date: Sat, 16 Apr 2016 16:53:19 -0700 [thread overview]
Message-ID: <CAMp4zn_AvTTY_veuKRw5uFu-EVcC9fU3xrDXHXHToFO9--UZtA@mail.gmail.com> (raw)
I'm working on instrumenting a TCP connections to assist in making
load balancing decisions elsewhere. Specifically, I'm looking to get
statistics for the time to connect, and notification of failed
connects. I initially tried to put kretprobes around
inet_stream_connect, but if the socket is in non-blocking mode that
notification happens asynchronously. I can't figure out a (good) way
to keep track of this data. Any suggestions?
