UNIX and LINUX are multi-user, multi-process systems and carry various business-critical applications and their server processes that were developed in C, C++, Java or another programming language. Availability and performance of the application is directly dependent on how effectively the operating system is managing hardware resources for simultaneous applications.

Applications are distributed over different processes that use various operating system services in kernel mode.

 

These services are:

• process administration
• storage administration
• device and file administration and input/output control
• authentication and access control
• logging and error processing

The following attributes are monitored and analyzed in detail:

 

• application processes in process groups (virtual storage, CPU time)
• processors (status, idle time, runtime)
• memory and swap space (size, fill level)
• file systems (size, fill level)
• memory (virtual and physical memory)

theGuard! ApplicationManager supports leading operating systems AIX, HP-UX, Solaris, Linux (various distributions) and Tru64 (DC Plattform Matrix).

Today, a wide range of these system resources can be virtualized through adaptive system architectures which partly set specific system management requirements.

This includes:

• Fujitsu Siemens Computer FlexFrame
• IBM Adaptive Computing Systems

• availability and performance – even for large multi-processor UNIX servers
• capacity planning and control of the application servers
• usage measurement
• supports adaptive system architectures
