With Aprobe version 5, we have extended our
Aprobe technology further
than we've ever gone before. While the basic structure of writing
probes remains the same, Aprobe 5 has been enhanced in the following
areas:
- Dynamically add and remove probes without stopping the program.
This works for Java as well as natively compiled applications. For
example, J2EE application servers can be instrumented and
uninstrumented without restarting the application server!
- Reduce the overall footprint dramatically, allowing probes to be
used on memory-constrained systems.
- Flexible logging support. The user can replace the supplied
logging routine to better support application-specific logging of
data. This is especially useful in embedded applications.
- Kernel and User Mode. Probes can be applied to both the
operating system and the user mode applications. You can add and
remove probes from the OS kernel, even while the application is
running!
How Aprobe 5 is used today
While we have
carefully designed Aprobe 5 to be portable to different operating
systems, we support the enterprise and embedded Linux applications and
kernels. We support both native (C, C++) and Java applications.
In fact, you may be using a device that already has Aprobe 5 inside!
Aprobe 5 is currently being used by a major embedded software OS vendor,
shipping under their own brand.

Is Aprobe 5 right for you?
There are currently three main audiences
for Aprobe 5: enterprises and projects
running their own version of Linux,
embedded Linux vendors, and ISVs.
 Enterprises –
Probes are an excellent testing and integration toolset, well-suited
to reduce integration costs associated with large software endeavors.
Additionally, enterprises and enterprise projects sometimes use their
own version of Linux that is maintained and modified independently from
a vendor-supported version. This is quite common in the case of embedded
Linux. Aprobe 5 can be quickly adapted to your unique version and
provides an extremely powerful general-purpose software tool, able to
instrument both the Linux kernel and the applications that run on it.
Aprobe 5 can provide much of the tool
support that an integrated toolset from
an external Linux vendor can.
Embedded Linux
vendors – Aprobe 5 is a unique and powerful technology that
can help differentiate your offering from commodity Linux.
Vendor-specific probes can be written to accentuate the strengths of
your offerings.
ISVs – Probes can leverage your existing products by adding
new capabilities through targeted uses of Aprobe 5 software
instrumentation. For example, vendors that sell enterprise monitoring
software can use software instrumentation to monitor new applications
and domains (through an OEM relationship).
Aprobe 5 supports the x86, PowerPC
and MIPS instruction sets.
How we can work with you
We are
flexible in our approach to providing Aprobe 5 technology to both
enterprises/enterprise projects and vendors. Aprobe 5 is already
shipping under an OEM agreement with a major embedded vendor as we
continue to pursue additional markets and relationships.
Enterprises
If you are an enterprise or a project within, we will work with you to
develop a lifecycle cost. This typically involves an initial licensing
fee and some level of ongoing support costs, although much depends on
the needs of the project and enterprise. In some cases, the
project/enterprise acquires a full source license and provides most of
their own support. In other cases, it might be more cost-effective for
us to provide the support. Regardless, we are committed to making Aprobe
5 work for you.
Embedded OS vendors
If you are an embedded operating system vendor desiring to bring out a
product version of Aprobe 5 for your Linux version, we will work with
you to develop the business case and invest appropriately to bring the
product to market with the goal of shared revenue.
ISVs
We are software instrumentation experts with more than 15 years of
experience behind us. Together, we can create a plan that is mutually
beneficial with shared risks and rewards.
