4.6.4 Using Graphical Tools
Several graphical tools are provided for fast checking of one or more
aspects of system performance. These are X-based utilities that will display
under any X-compliant windowing interface. Under the Common Desktop
Environment, (CDE) the interfaces are organized under the Tool Drawer
icon, on the CDE front panel. This icon displays the Application_Manager
folder, which contains monitoring tools in the following sub-folders:
• Desktop_Tools – This folder contains simple interfaces such as System
Load to monitor CPU usage or Disk Usage to obtain the current status
of the file system space per disk.
• System_Admin – This folder provides two sub-folders that contain tools
useful for monitoring:
– MonitoringTuning – Contains graphical interfaces such as the
process tuner,
proctuner and the kernel tuner dxkerneltuner
that are useful for checking and changing system settings.
– Tools – contains graphical interfaces to command-line utilities such
as iostat and netstat that enable you to constantly monitor the
output, setting your preferences for update and display.
As with any graphical application, you can place the icons on the System
Administration Desktop for quick access to system information or keep the
displays open constantly to monitor any aspect of system performance.
Executables for the graphical interfaces are located in /usr/bin/X11.
4.6.5 Using sys_check
The sys_check tool is used to produce an extensive dump of system
performance parameters. It enables you to record many system values and
parameters, providing a useful baseline of system data. This may be
particularly useful before you undertake major changes or perform
troubleshooting procedures.
The sys_check can optionally produce an HTML document on standard
output. Used with the -escalate, flag the script produces a
/var/tmp/escalate* output files by default. These files can be escalated
to your technical support site and used for diagnosing system problems and
errors. Use the following command to obtain a complete list of options:
# /usr/sbin/sys_check -h
Note that the output produced by sys_check typically varies between
0.5MB and 3MB in size and it can take from 30 minutes to an hour to
complete the check.
