System statistics probe
The System Statistics (Systat) probe runs on Windows™ or Linux™ and captures key system statistics for the target host.
The following table lists those statistics.
| Counter | Description |
|---|---|
| Total CPU load | Percentage average load over all CPUs. |
| CPU 1 load | Percentage load on a single CPU. |
| CPU 2 load | Percentage load on a single CPU. |
| CPU 3 load | Percentage load on a single CPU. |
| CPU 4 load | Percentage load on a single CPU. |
| Used memory | Percentage used RAM. |
| Disk busy % | Percentage of time the hard disk(s) is (are) being read or written to. |
| Network usage | Percentage of available bandwidth used. |
| CPU threads saturation | Number of threads waiting for the CPU against total threads. |
| Memory saturation | Number of pages against number of page faults. |
| Disk saturation | Disk I/O operations waiting to execute against executed operations. |
| Network saturation | Rate of network errors for last time period. |
| Used swap space | Percentage of used swap space. |
The Systat probe also captures key process statistics for the target host. The following table lists those statistics.
| Process | Description |
|---|---|
| Per-process CPU load | Percentage CPU load exerted by a specific process. |
| Pre-process memory consumption | Memory consumption (in kilobytes) exerted by a specific process. |
Note: This applies to the Systat probe running on Windows™ only. The Systat probe requires the installation of the Microsoft™ Visual C++ 2010 Redistributable package on each target host
that is to be monitored. The package is available in 32-bit and 64-bit versions and can be
downloaded from the Microsoft™ website. If you have
installed the 32-bit version of Rational® Integration Tester
Agent, you must
install the 32-bit version of the Microsoft™ Visual C++
2010 Redistributable package. Alternatively, if you have installed the 64-bit version of Rational® Integration Tester
Agent, you must
install the 64-bit version of the Microsoft™ Visual C++
2010 Redistributable package.
Note: This applies to the Systat probe running on Linux™ only. To run the system
statistics probe on Linux™,
you must install Libstatgrab version 0.17 library.
This library is used to provide access to statistics about the system
on which the probe is run. Note that later versions of Libstatgrab
are available, but these are not supported by the system statistics
probe. Libstatgrab can be downloaded from http://www.i-scream.org/. To build
and install the library, follow the instructions provided with the
download.
