R: Re: Monitor all outbound connections from apps in warden

Michael Grifalconi <michael.grifalconi@...>

Hello, thank you for the hint!

I'd prefer to do something at application level, like a shell script to run in parallel to the application that every X seconds prints the output of netstat, as the standard output is taken as a log on CF apps. Is it possible?

(I'm really sorry and embarrassed about the spam after my email signature, this is due to my University and I can't avoid it :/ )

Thank you,

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.

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!
