The Chef file and folder locations are different on Linux and Windows machines. This article explains the purpose of each file and the location.
|Chef Client run log||/var/log/chef.log||First run only
|Subsequent Chef client runs
|Recommended location for custom log files||/tmp/cheflog.log||C:\Logs\Chef\cheflog.log|
|Chef Client configuration||/etc/chef/client.rb||C:\chef\client.rb|
When you test your cookbook in Test Kitchen
The .kitchen.yml file contains the username to execute the Chef cookbook. It is specified under platforms:, transport:, username:
Use that value in place of USER-NAME-FROM-KITCHEN-YML below.
When the Chef recipes are executed, all cookbooks are stored on the node. You can examine the code to make sure your latest changes are reflected on the machine.
The log of the Chef client run
The output of the Chef cookbook execution is in the chef.log or chef-client.log file
The log of the first Chef Client run and subsequent runs are stored in different log files. After the initial Chef Client run, the rest of the log entries are collected in the second file.
Chef saves information on the hard drive when scripts are executed. If there is a failure, the stack trace of the last error is saved in the chef-stacktrace.out file.
All the information that Ohai collects on the instance, is saved in the failed-run-data.json file, even if there is no error. It is a great resource to get the server specific values.

To get detailed information on the Chef run, start the Chef Client in debug mode. Execute the command in sudo mode, because many Chef steps require elevated rights.
chef-client -l debug -L debug.txt
The debug information is saved in the debug.txt file in the current folder.
