An internet shopping mall was experiencing frequent system errors and crashes from a new interactive flash program. The system operator could not determine the root cause of the issues through standard Windows performance monitoring tools. After installing OnTune to monitor system and process resource usage, the operator discovered that the virtual memory usage of the flash program was steadily increasing until it caused the system to crash. This identified a memory leak in the flash program code. The developer was notified and fixed the problem, resolving the system crashes.

Case
For an internet shopping mall, a system operator developed an interactive table with flash,
installed and operated the system. But the customer faced frequent system errors, and finally
was not able to provide the service.
Issue
After the internet shopping mall opened, the new developed flash program was executed
for 2 hours, and then it became to be crashed steadily so that it couldn’t provide continual
services.
- There was no way to figure out the system status for the Operating System
(Windows).
: The System Operator considered implementing data logging through ‘perfmon’
provided by windows, but he couldn’t decide which value should be done logging
above lots of performance counters. Even though he completed logging, he faced
difficulty for analyzing huge data which didn’t stand out well
- In case of making down the interactive table for Application Debugging, it is
impossible to do requested service process, neither able to see the process of actual
applications, which means the System operator cannot figure out the root cause of the
problem.

Solution
To solve the problem, onTune, which is the specialized solution for monitoring and
analyzing system performance, was installed in the target system. And it found the root cause
and solved the problem.
- Installed onTune in the Windows server including the problematical application
- Without certain configurations, the usage of CPU/Memory/IO for the entire system
was saved by second unit, as well as the usage of CPU/Memory/IO for every single
process with PID, and obviously those data was saved with every second interval
monitoring.
- As a result of analyzing resource usage such as CPU or Memory of processes through
onTune, the system operator found that the virtual memory usage of the problematical
Flash program was steadily increased, and it showed down when it reached to the
certain size.
- Based on this fact, the system operator requested the program developer to confirm
the problem. Confirming the memory leak of the program, the developer took action
for fixing the problem.
lesson and learned
Thanks for onTune, system operators are able to implement logging resource usage of
every single process by second interval, as well as the global resource usage of system.
Furthermore, certain past time when problems happened is being monitored so that the users
can analyze the resource usage of processes, so it must be helpful for figuring out the root
cause of problems.

working on the server.
