How to enable trace logs in the build environment?

by Xavier Dilip Kumar 18. March 2014 11:19


Following are the steps to enable trace logs in the build environment

1. On the Build machine (both controller and agent) ,  copy the attached .config file (TFSBuildServiceHost exe.config (2.25 kb)) to C:\Program Files\Microsoft Team Foundation Server 2010\Tools.

2. Create a new directory named c:\logs and ensure that the account under which the service Visual Studio Team Foundation Build Service Host has write permission on c:\logs.

3. Restart the build controller/agent service (net stop tfsbuildservicehost & net start tfsbuildservicehost).

4. Trace log will be generated under c:\logs

Steps to enable log in the windows event viewer 

1. On the Build machine, go to Event Viewer and navigate to the following path:

  • Application and Services Logs\Microsoft\Team-Foundation-Server\Build-Services.

 2. We want a detailed level tracing:

  • Go to the ‘View’ menu and select ‘Show Analytic and Debug Logs’. Once you do that there will be 2 channels available under this event source, Operational and Analytic

** The operational log is always on and provides high-level auditing of failures and events, while the Analytic log is off by default and provides very detailed information about activities in the build machine.


** You can enable the Analytic log, by right click and select Enable Log.

How to clone a build definitions from one project to another within a same collection?

by Xavier Dilip Kumar 7. March 2014 12:31


You can use TFS power tools command line utility to clone a build definition across projects

Note: You can download and install TFS Power Tools from http://visualstudiogallery.msdn.microsoft.com/b1ef7eb2-e084-4cb8-9bc7-06c3bad9148f

1. Open "Visual Studio" command prompt

2. You can use the following command to preview the build definition clone

tfpt builddefinition /clone "<Source Team Project Name>\Build Definition" "<Target Team Project Name>\Build Definition" /Collection:http://tfs:8080/tfs/DefaultCollection /preview

3. You can use the following command to clone the build definition

tfpt builddefinition /clone "<Source Team Project Name>\Build Definition" "<Target Team Project Name>\Build Definition" /Collection:http://tfs:8080/tfs/DefaultCollection

Only the well-defined build definition can be cloned using this approach meaning the build source build definition should have all the mandatory (required) properties filled with values

For example:

The source build definition without Build controller name cannot be cloned using this approach.

You can also use * wildcard character to clone all build definitions at one shot, provided you have well-defined build definition at source team project.

tfpt builddefinition /clone "<Source Team Project Name>\*" "<Target Team Project Name>\"  /Collection:http://tfs:8080/tfs/DefaultCollection

Remember to update the following build properties to the cloned build definition. 

1. Disable build definition to prevent accidental triggering.

2. Change workspace mapping to target team project source.

3. Change drop location.

4. Change the build process template to point to the right projects.

5. If you use custom build workflow/tasks, make sure your build controller custom assembly references are pointed to target team project source control

6. Enable the build definition.
