Setting Alert Actions in Red Hat Linux

When you set Alert Actions for an event on systems running a supported Red Hat Linux operating system, you can specify the action to "display an alert on the server." To perform this action, Server Administrator writes a message to the console. If the Server Administrator system is running X Windows, you will not see that message by default. To see the alert message when X Windows is running, you must start xconsole 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 system running Server Administrator is running X Windows, you will not see that message by default. To see the broadcast message when X Windows is running, you must start a terminal such as "gnome-terminal" before the event occurs.

When you set Alert Actions for an event, you can specify the action to execute an application. Limitations are on the applications that Server Administrator can execute. Follow these guidelines to ensure proper execution:
