Tag sessions when slow response time & scripting

[fred]

Guys,

I frequently receive from customers Fiddler traces and need to analyze them. Especially when slow response time is the problem I try to identify, I would like to as you a few questions :

1) Do we have a way (not while capturing, but reviewing a trace offline) to ask fiddler to identify for me sessions that are slow. For example <500 ms put color green, 500 to 1 sec orange, and >1 sec red ?

2) Also, do we have a way to use a script (VBS or PowerShell) to parse (and modify) a fiddler Trace. For example "For Each line... check response time (overall_elapsed)... if 500 to 1 sec add a comment such as 'very slow'. Idea would be to quickly identify common scenario that I encounter for my products when slow.

Again that is an offline (not real time) analysis sent by customers.

Thanks a lot for your advice !

Hello,

As for 1) that http://docs.telerik.com/fiddler/KnowledgeBase/FiddlerScript/CustomizeSessionsList should get you started on modifying the sessions list appearance.

I am not really sure I completely understand what you are trying to do in 2). I assume the users are sending you SAZ files. Do you want to modify these? Where do you want to add the comment?

Hi,Thanks a lot for your feedback.

You are right, I get a SAZ file and usually start by parsing each line, look at some parameters, and take a few notes.

My feeling is that I usually start doing the same things all the time and try to automate it.

So wonder if I can read/write a SAZ file (VBS for example), and that would be an example

FOR each Line... check response time (overall_elapsed)... if 500 to 1 sec add a comment such as 'very slow'. Idea would be to quickly identify common scenario that I encounter for my products when slow.

this way I can see how to read each line, and potentially write stuff in the comments. That would save a lot of time I think.

Thanks for your advice !

Ah I see now.

Well the SAZ file is just a zip file. Here is a more detailed description of its format - http://fiddler.wikidot.com/saz-files. So it is easy to modify it grammatically and then zip it back again. 

Adding a comment in your case would look something like adding 

<SessionFlag N="ui-comments" V="'very slow" />

to sessid#_m.xml.
