With kcweb alarms can be set for certain parameters. It is possible to be alarmed if e.g. nproc
usage is greater than 80%. kcweb alarms use EMS notifications. All alarms are managed by
kcalarm(1M).
Range checking
Another change compared to UX 11.00/11.11 is that the range checking of tunables is now
performed directly in the kernel. kctune reports out of range errors, kcweb shows stderr output
of kctune.
Help
You can access the man page of each tunable and get a detailed explanation.
Command preview
A great advantage compared to SAM is that for each task (e.g. modifying a tunable, module,
or alarm) you can use the command preview feature by choosing the ? button; this will show
the kernel configuration command invocation that will perform the requested task.
kcweb can be launched from SAM GUI (as of UX 11.23 additionally from SAM TUI) or
manually. To access kcweb interface start the kcweb server on the system and access it from any
browser.
# kcweb -s startssl

This creates server certificates (if needed), starts the kcweb administration server, connects
to the server and presents a login screen.
At the following address you can access kcweb:

After logging in as root you will see the following window:
