This tool helps you analyze SIP call in the diagnostic logs from Expressway and VCS. It provides an overview of all the SIP Calls present in the logs as well as all the RTP Streams (when a packet capture is present in the archive):
For each call additional details are provided, such as:
Tool developers:
Kristof Van Coillie - Technical Leader Services
Vladimir Sidimak - TAC Engineer
Necati Cehreli - TAC Engineer
Analyzing diagnostic logs and packet captures can be time consuming and difficult as you need to find the call you are interested among possibly hundreds of other calls. This tool gives you a quick overview of all the SIP Calls, provides you useful information and shows you the relevant messages.
It helps to troubleshoot:
Cisco Expressway
Cisco Video Communication Server
How to use this tools:
This tool looks extremely helpful for MRA deployment (which we're in the process of turning up). In trying to experiment with the tool, I'm not having any success, so I have a couple of questions:
1. When a diagnostic log is captured on the VCS, and the archive is downloaded <name.tar.gz>, is that file simply drug into the window of the Analyzer Tool?
I've captured logs which included SIP calls, drug the archive into the file window on the Analyzer Tool, but the output is empty/unpopulated.
2. Do any diagnostic logging capture levels have to be increased above a value of INFO, or is this sufficient? (Instructions aren't terribly detailed in this area...unless I've missed something.)
Thanks,
Greg
Hi Greg,
1. That is correct: you just start the logging (this will set the correct debug levels), do the test, stop the logs and download them. You can upload the archive that you downloaded to the tool.
2. You don't have to update any log levels, this is taken care of in the background when you start the logs. I will update this section in the document to have it more clear, thanks for the feedback.
Could you send me the archive which is not giving any output so we can investigate: kvancoil@cisco.com
Best Regards,
Kristof
Kristof,
Thanks for the timely reply. After reading your clarification, I uploaded another archive file, and was able to successfully view the contents in the tool as described here.
I think this tool will prove very helpful for troubleshooting SIP issues as we deploy MRA.
One more question: Will this tool ever be made available for download and use in a (licensed?) off-line/local scenario by Cisco customers?
Greg
Hi Greg,
Thanks for the feedback, we don't have any immediate plans to make the tool available for offline use; would this be to analyze logs on deployments where internet access is not allowed?
We are working on releasing more features (such as analyzing also MRA logins and SIP Registration sessions), I hope we will be able to release that soon.
Best Regards,
Kristof
I do quite a bit of work with Expressway customers and this tool has saved me hours of troubleshooting in the past week alone.
I can remember the wow factor I experienced when I opened TranslatorX for the first time, this tool gave me the same feeling.
Huge thanks to Kristof, Vladimir, and Necati for developing this tool!
