This TeamCity server plugin is a build agents comparison tool particularly useful when investigating environment-dependent test failures.
The plugin adds the Diff tab to the Agents page where you can select the build agents to compare and see the differences in the agents' parameters.
When looking into a problem on a particular build agent, quick navigation is provided with the Go to build agents diff page link available on the Agent Summary page.
Install the plugin as usual.
Stable, production quality.
