Agent asynchronous transaction monitor
A system monitors asynchronous transactions over a different number of threads by capturing data and tracking transitions in the particular framework. Once an asynchronous method is called, the transition framework may be tracked while executing a asynchronous method call. Within a .NET framework, monitoring may include tracking a task object return, continuation method calls at the completion of a method, and tracking the continuation method as it executes other code. The asynchronous method may then be correlated within a business transaction using the returned task object data.
1. A method for monitoring an asynchronous transaction, comprising:
detecting, by an agent executing on a server, an asynchronous method call within an application;
determining whether to monitor the detected asynchronous method call;
responsive to the determining, instrumenting the asynchronous method call to be monitored;
responsive to the instrumenting, tracking, by the agent, asynchronous .NET framework transitions initiated by the instrumented asynchronous method call;
obtaining asynchronous .NET framework transition data based on the tracking; and
correlating the asynchronous .NET framework transition data with a distributed business transaction performed at least in part on the server.
2. The method of claim 1 , wherein the instrumenting includes performing byte code instrumentation on the asynchronous method determined to be monitored.
3. The method of claim 1 , wherein the asynchronous method determined to be monitored includes a continuation method.
4. The method of claim 1 , wherein tracking includes collecting data associated with a returned task object sent in response to the asynchronous method call.
5. The method of claim 1 , wherein correlating includes identifying a method that received returned task object.
6. The method of claim 1 , wherein correlating includes correlating asynchronous method and the method that called the asynchronous method.
7. The method of claim 1 , further comprising reporting performance of a distributed business transaction that includes a call to the asynchronous method.
8. The method of claim 1 , wherein the instrumenting includes creating a new method that encompasses the asynchronous method to be monitored within a wrapper.
9. A non-transitory computer readable storage medium having embodied thereon a program, the program being executable by a processor to perform a method for monitoring an asynchronous transaction, the method comprising:
detecting, by an agent executing on a server, an asynchronous method call within an application;
determining whether to monitor the detected asynchronous method call;
responsive to the determining, instrumenting the asynchronous method call to be monitored;
responsive to the instrumenting, tracking, by the agent, asynchronous .NET framework transitions initiated by the instrumented asynchronous method call;
obtaining asynchronous .NET framework transition data based on the tracking; and
correlating the asynchronous .NET framework transition data with a distributed business transaction performed at least in part on the server.
10. The non-transitory computer readable storage medium of claim 9 , wherein the instrumenting includes performing byte code instrumentation on the asynchronous method determined to be monitored.
11. The non-transitory computer readable storage medium of claim 9 , wherein the asynchronous method determined to be monitored includes a continuation method.
12. The non-transitory computer readable storage medium of claim 9 , wherein tracking includes collecting data associated with a returned task object sent in response to the asynchronous method call.
13. The non-transitory computer readable storage medium of claim 9 , wherein correlating includes identifying a method that received returned task object.
14. The non-transitory computer readable storage medium of claim 9 , wherein correlating includes correlating asynchronous method and the method that called the asynchronous method.
15. The non-transitory computer readable storage medium of claim 9 , the method further comprising reporting performance of a distributed business transaction that includes a call to the asynchronous method.

a processor;
a memory; and
one or more modules stored in memory and executable by a processor to perform operations including:
detect, by an agent executing on a server, an asynchronous method call within an application;
determine whether to monitor the detected asynchronous method call;
responsive to the determining, instrument the asynchronous method call to be monitored;
responsive to the instrumenting, track, by the agent, asynchronous .NET framework transitions initiated by the instrumented asynchronous method call;
obtain asynchronous .NET framework transition data based on the tracking;
and correlate the asynchronous .NET framework transition data with a distributed business transaction performed at least in part on the server.
17. The system of claim 16 , wherein the one or more modules are configured to perform byte code instrumentation on the asynchronous method determined to be monitored.
18. The system of claim 16 , wherein the asynchronous method determined to be monitored includes a continuation method.
19. The system of claim 16 , wherein tracking includes collecting data associated with a returned task object sent in response to the asynchronous method call.
