Notes:
Each line represents a gross category of CPU usage. The numbers in each line are:
• total CPU time used (in 100'ths of seconds) since boot (can wrap around)
• percentage of available CPU time used since the previous 'diag dev'
• the count of events since the last 'diag dev'.
The most useful part of the report is the percentage (2nd number).
Category key:
con - arriving system console characters (very small)
sch & sclk - system scheduler clock ticks
eth0 - low-level handling of transmitted or received packets
SW+0,1,2 - handling TCP traffic
sys - total time used by applications in common platform code
app - total time in application code
sched - idle time
(sys, app, and sched do not have event counts)
The elapsed time since the previous 'diag dev' can be derived from the 'sclk' category report; its
event count represents clock ticks, or 1/100ths of seconds.

ILL C ONSOLE – DIAG KILLCON
Syntax: diag killcon <instance> | platform
The diag killcon command provides a means to free up the telnet port of an instance or the
platform in case someone left it connected and someone else needs to use it. The telnet
connection is broken without terminating the instance or rebooting the platform. Since TCP does
not provide an approved means for a third party to break the connection, this command should not
be routinely used. It does not, for example, shut down or notify the far-end telnet client. Only when
the client tries to send new input will it find out the connection is broken.
To avoid the need to use the diag killcon command, and to increase security, it is recommended
that all application consoles and the platform console be configured with a timeout (via the timeout
command) that automatically logs off the console after a period of activity.
