Tx allows you to do Language Integrated Query (LINQ) directly on raw event sources:

  • ad-hoc query on past history in trace and log files
  • standing queries on real-time feeds, such as Event Tracing for Windows (ETW) sessions

The Tx approach is different than Databases, Hadoop, Splunk, Dapper, etc. which all require a stage of uploading before the events become available to queries. Instead, mixing Reactive Extensions (Rx) and LINQ-to-Objects allows the query to be embedded anywhere including:

Here is a map of the dependencies among the main Tx components:

  • Dark green is .Net
  • Light green is mature open source
  • Light grey are framework components, also available on NuGet
  • Darker gray are tool experiences that come with Tx
  • White are samples

See when to use Tx, versus only using the underlying technologies (LINQ-to-Objects and Rx)

There are two ways of getting the Tx source code:

  • Click on the SOURCE CODE tab, and then on the Download button
  • Using Git as source control:
    • Install Github for Windows
    • launch the Github Shell, and type: git clone

The first method is a quick way to take first look at Tx, or debug a problem.
The second allows you to pull subsequent changes, see the history, etc.
