Lifecycle Application Diagnostics for C/C++
Trace, profile or find memory leaks in any C/C++ application
- Determine why your application is slow
- Find memory leaks or over-utilization in your
application
- Trace your application to find bugs, understand the
control flow as well as object and thread interactions.

The Execution Flow profiling
view shows the execution flow within each thread. Each call
within a thread is shown as a vertical stripe. |
Hitchhiker is a free Eclipse plug-in and runtime
engine based on patented Aprobe technology. Hitchhiker provides
tracing, profiling, memory leak tracking and function coverage tools for
C/C++ applications. With Hitchhiker you can:
- Instrument any C/C++ application on the fly using
patented Aprobe technology
- Trace and profile the application at near full
execution speed
- Visualize application internals using the Eclipse
Workbench.
Hitchhiker can be used throughout the application
development lifecycle, from development into alpha, beta, production
test, and production.
How Hitchhiker works
Hitchhiker collects performance and control flow data
from your application using machine code instrumentation that is
automatically inserted into your application using patented Aprobe
technology.

The UML2 Object Interactions profiling view
shows the sequence of method invocations for each object. |
Configure the data collection process by specifying the
wild card set of functions to profile as well as other data collection
options using the Eclipse Workbench. Then launch the application via the
standard Eclipse Launch Dialog. Or you can attach to an application
already running with the Hitchhiker
agent and examine its collected profile information.
As the application runs, the Hitchhiker Agent sends the
application telemetry back to the Eclipse Workbench. The collected data
can be viewed in real time using a variety of data visualization views
or saved for later analysis.
The data can be analyzed in many different ways:
- Identify objects and methods that consume the most
time
- Identify memory-intensive classes
- Gauge program concurrency
- Locate memory leaks
- Browse every execution of a method as a function of time
- Obtain a wider view of execution behavior as a function of time
- Identify active threads, and when threads are active
- Identify frequently called methods
- Identify different phases of program execution
- Study different method invocations
