Hi,

Is there a way to capture chef-client communication with chef server by running Fiddler on the node? I tried running Fiddler with HTTPS capture enabled, but did not see any captures in Fiddler.

Thanks

What data are you looking for in particular? If you run chef-client with -l debug, it will display most HTTP data before sending it.

Yesterday, during chef-client run, I saw "content length mismatch" error on Template and cookbook\_file resources in one of my recipes. I wanted to see what is being sent to and from the chef-server to determine the cause of this issue.

Can fiddler or something similar be used to capture the traffic?
