Spotlight on DB2 6.9.3 - User Guide

Used Percentage Alarm

The Least Space / Disk Space container in the Disk Activity panel displays the percentage of used disk space for the specified filesystem.

The Used Percentage alarm indicates that the filesystem is full or filling up. If the filesystem fills up completely, no more data can be written to it. For example:

• If the /var filesystem fills, you may have problems with system activities such as e-mail or printing.
• If the /home filesystem fills, user applications may be affected.
• If the /tmp filesystem fills, any applications that use temporary files may be affected.

Notes: 

• The data displayed in the Least Space / Disk Space container is collected from:

• The filesystem that has the least amount of free space, OR
• A user-specified filesystem on the Unix host.

• To choose the filesystem whose details are displayed in the container, right-click the container and select Disk Options.

Zombie Processes Alarm

The Zombie button in the CPU panel shows the number of terminated child processes that have not been acknowledged by their parent process.

A high level of zombie processes is indicative of the presence of an inferior program, or an entry in /etc/inittab (or equivalent) preventing init from completing its startup sequence.

The type of alarm that is activated is determined by the number of zombie processes waiting to be exited.

Spotlight Drilldowns

When you have isolated a problem, you can display a drilldown page, whose charts and tables provide a detailed breakdown of the underlying statistics.

Following are Spotlight drilldowns.

Drilldown	Click to open	Keyboard Shortcut	Description
Processes and Services		CTRL+P	The pages in the Processes and Services drilldown list all the processes running on the Unix machine (including "zombie" processes), and all the services found in the /etc/services file (running or not). Useful features in this drilldown include: Processes Page: View processes in a standard table or tree structure. In the tree structure secondary processes are shown as "children" of the processes that run them. Click on a process for more detailed information on that process including CPU and Memory utilization. From the Memory Usage chart it is possible to detect memory leaks of the process over the display period. Zombies Page: View child processes whose termination has not been acknowledged by their parent process. Services Page: Use a shortcut menu option to test whether a specified service is available.
Activity Summary		CTRL+A	The pages in the Activity Summary drilldown — Activity Page Disk Page Memory Page CPU Page Network Page Logins Page — show details of the different types of activity on the Unix system.
Filesystems		CTRL+S	The Filesystems And Disk Information drilldown displays detailed information about the filesystems on the Unix machine. This information can be viewed in chart or table form: right click over the drilldown page.
Alarm Log		CTRL+L	The Alarm Log drilldown displays information on the alarms associated with the Unix machine.
