Re: [Gluster-devel] [wireshark] TODO features
Hi Niels, Thanks for all your inputs and help, I have submitted a patch: https://code.wireshark.org/review/1833 glusterfs: show filenames in the summary for common procedures With this patch we will have filename on the summary for procedures MKDIR, CREATE and LOOKUP. Example output: 173 18.309307 192.168.100.3 - 192.168.100.4 GlusterFS 224 MKDIR V330 MKDIR Call, Filename: testdir 2606 36.767766 192.168.100.3 - 192.168.100.4 GlusterFS 376 LOOKUP V330 LOOKUP Call, Filename: 1.txt 2612 36.768242 192.168.100.3 - 192.168.100.4 GlusterFS 228 CREATE V330 CREATE Call, Filename: 1.txt Thanks, Vikhyat - Original Message - From: Niels de Vos nde...@redhat.com To: Vikhyat Umrao vum...@redhat.com Cc: gluster-devel@gluster.org Sent: Tuesday, April 29, 2014 11:16:20 PM Subject: Re: [Gluster-devel] [wireshark] TODO features On Tue, Apr 29, 2014 at 06:25:15AM -0400, Vikhyat Umrao wrote: Hi, I am interested in TODO wireshark features for GlusterFS : I can start from below given feature for one procedure: = display the filename or filehandle on the summary for common procedures Things to get you and others prepared: 1. go to https://forge.gluster.org/wireshark/pages/Todo 2. login and edit the wiki page, add your name to the topic 3. clone the wireshark repository: $ git clone g...@forge.gluster.org:wireshark/wireshark.git (you have been added to the 'wireshark' group, so you should have push access over ssh) 4. create a new branch for your testing $ git checkout -t -b wip/master/visible-filenames upstream/master 5. make sure you have all the dependencies for compiling Wireshark (quite a lot are needed) $ ./autogen.sh $ ./configure --disable-wireshark (I tend to build only the commandline tools like 'tshark') $ make 6. you should now have a ./tshark executable that you can use for testing The changes you want to make are in epan/dissectors/packet-glusterfs.c.

It does not really matter on how that function gets executed, that is more a thing for an other task (add support for new procedures). In the NFS-dissector, you can see how this is done. Check the implementation of the dissect_nfs3_lookup_call() function in epan/dissectors/packet-nfs.c. The col_append_fstr() function achieves what you want to do. Of course, you really should share your changes! Now, 'git commit' your change with a suitable commit message and do $ git push origin wip/master/visible-filenames Your branch should now be visible under https://forge.gluster.org/wireshark/wireshark. Let me know, and I'll give it a whirl. Now you've done the filename for LOOKUP, I'm sure you can think of other things that make sense to get displayed. Do ask questions and send corrections if something is missing, or not working as explained here. This email should probably get included in the projects wiki https://forge.gluster.org/wireshark/pages/Home some where.
