Explanation:

This feature is not available in TFS 2013.

Solution:

You can set the verbosity in build definition using MSBuild arguments section in process tab

/flp:verbosity="<verbosity>"

Following are the levels of verbosity that can be set for the ms build output:

· Quiet
· Minimal
· Normal
· Detailed
· Diagnostic

Explanation:

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.

Solution:

You can override the polling interval by modifying the value in the windows registry. 

[HKCU\Software\Microsoft\VisualStudio\10.0\TeamFoundation\Build\BuildNotification\Subscriptions]

(REG_SZ) PollingInterval = "00:02:00"

By default, polling interval is set to "00:02:30" or 2.5 minutes. Modifying this value will result in increased load on your TFS server
