Hello,
I have been working on enabling TMF to read pcap traces. I am an intern
within Ericsson Montreal, and this is my summer project, so I'll spend
all my time on it.
So far, TMF can read pcaps and recognize a couple of protocols
(Ethernet, IPv4, TCP/UDP). There is currently a perspective that
displays the packets in a wiresharky way (there is a view that list all
the packets, another view shows packet details, and another view that
allows packet filtering although it is really limited ATM).
The goal is not to make a wireshark clone, but to offer some new
functionality and features that wireshark doesn't have. Also, since we
are a framework, I would also like to have it as easily extensible as
possible, and make it easy to add new types of packet (which would be
good for Kalray's usecase).
The cool thing is that you can already correlate packets with other
events (kernel, userspace, etc), since it uses the default TMF views. In
the following weeks I would like to:
- Improve the filter view, to be able to filter per packet/event field.
Filtering is probably the most used feature of wireshark and having a
good filter view in TMF is primordial.
- Add stream (conversation) based views. Basically, it filters the
packets between two hosts (endpoints) and analyze it.
- Make nice graphs that are meaningful to network engineers
- Add more protocols (the widely used ones)
- Make the pcap parser faster (there is so much room to improve it)
- Support pcapng
The prototype is pretty limited ATM. There is a LOT of work to be done.
If Kalray and Redhat (and others) would like to collaborate, that would
be awesome. Input are very welcome. The more input the better.
Best regards,
Vincent

Hi,
Wireshark replacement was not our top priority this year, wireshark is
already open source and doing a great job.
Having said that it is not the first time people are asking about pcap
and wireshark for TMF, it make sense because people want to correlate
the pcap network protocol tracing/monitoring info with other layers in
the system, e.g. middleware, other libraries, proprietary code, KVM,
libvert, QEMU, kernel, etc.
We are doing an investigation this summer for a pcap
parser/visualizer, collaboration from RedHat, Kalray or others is of
course welcome, we can setup an online meeting if need be.
Best Regards,
Dominique.

Hi TMF guys,
I'm just back from the EclipseCON France. During the EclipseCON
france, I had the opportunity to present TMF with a live demo.
After that, I had a discussion with Redhat guys, about having
something similar to wireshark in Eclipse, using TMF.
Today, I checked my emails, and a saw that:
https://git.eclipse.org/r/#/c/27887/
Is it possible to have more info about that? (Planning, expected
features, ...)
In particular, Kalray may be interested: use-case is to monitor and
visualize traffic on the MPPA NoC.
