Subject: Is it ok to insert a module multiple times with staprun?
Date: Thu, 30 Mar 2017 04:41:00 -0000	[thread overview]
Message-ID: <CAJQX3DyhKKCn6U+T4oBcMs6NHHo1zQwsD2fASjnytiTdGKYz5w@mail.gmail.com> (raw)

Hi,
In the staprun manpage, I saw this:


-R     Rename the module to a unique name before inserting it.

So looks like it's safe to insert it multiple times as long as the -R
gives a different name.


My application scenario is to log information on different tcp
connections, and separately output them to different files.
The invocation is like this:
# first insertion
sudo staprun /path/to/module -o /path/to/tcp-2003 filterport=2003 -R tcp-2003
# second insertion
sudo staprun /path/to/module -o /path/to/tcp-2004 filterport=2004 -R tcp-2004

Does the above approach look natural?

Regards.
