You could set up a security group that logs all outbound connections.
These are logged on the DEAs.
You would then need to correlate the warden handle with the application.

I'm working with the docs team on getting this feature properly documented.

Relevant stories where this feature was added.

I don't know how you would do this via buildpacks.

Hello all,

How can I monitor (and log) all the outbound connection made from an
application?

I would like to do by editing buildpacks:

edit the buildpack to run a netstat command every 10 sec and send a log of
the estabilished connections..


I would also be able to sniff the traffic, is it possible to run a tcpdump
with some filters and send logs with the result? All by editing the
buildpack. I think the process will not have the necessary privileges..


Any hint is appreciated!

Thank you!

Michael
