Establishing a Power Control Session
If you have an AlterPath PM powering one or more computers connected to
your KVM unit, you may initiate a power control session at any time once you
are connected. You first connect to the desired computer following the
Connecting to a Server
section of this chapter. Then press, at any time, the
power command key sequence (
Ctrl-K
then
P
, default).
If you have correctly performed the Power Outlet configuration option as
described under Server Configuration (Chapter 3), the system will bring you a
Power management window which will:
•
Indicate if the power outlet configured for the selected server is ON
or OFF.
•
Allow you to select power ON, OFF, or CYCLE.
•
Allow you to exit from the Power Control Session.
Logging Events
You can audit the use of your KVM unit by checking log files. Logging
capabilities and message treatment are supported through a daemon called
syslog-ng.
Its basic function is to read and log messages to the system console;
log files, remote servers and/or users as specified by its configuration file.
The
syslog-ng
can filter messages based on their content and perform an
action (
e.g
., send an email or a pager message). To access this function, you
need to configure the
syslog-ng.conf
file.
The
syslog-ng.conf
file is read at startup and is re-read after receiving a hang-
up signal. When reloading the configuration file, all destination files are
closed and re-opened as appropriate. The
syslog-ng
reads from various
sources (files, TCP/UDP connections, syslogd clients), filters the messages
and takes an action (writes in files, sends SNMP trap, pager or email, or
syslogs to a remote server).
