Setting Alert Actions
Setting Alert Actions for Systems Running
Supported Red Hat Enterprise Linux and SUSE
Linux Enterprise Server Operating Systems
When you set alert actions for an event, you can specify the action to display
an alert on the server. To perform this action, Server Administrator sends a
message to /dev/console. If the Server Administrator system is running an X
Window System, you do not see that message by default. To see the alert
message on a Red Hat Enterprise Linux system when the X Window System
is running, you must start xconsole or xterm -C before the event occurs. To
see the alert message on a SUSE Linux Enterprise Server system when the X
Window System is running, you must start xterm -C before the event occurs.
When you set Alert Actions for an event, you can specify the action to
Broadcast a message. To perform this action, Server Administrator executes
the wall command, which sends the message to everybody logged in with
their message permission set to Yes. If the Server Administrator system is
running an X Window System, you do not see that message by default. To see the
broadcast message when the X Window System is running, you must start a
terminal such as xterm or gnome-terminal before the event occurs.
When you set Alert Actions for an event, you can specify the action to
Execute application. There are limitations on the applications that Server
Administrator can execute. Follow these guidelines to ensure proper
execution:
• Do not specify X Window System based applications because Server
Administrator cannot execute such applications properly.
• Do not specify applications that require input from the user because
Server Administrator cannot execute such applications properly.
