Broadcasts an event or a rearm event to all users who are logged in.
wallevent [ -h ]
The wallevent command broadcasts a message on an event or a rearm event to all users who are currently logged in to the host when the event or the rearm event occurs. Event or rearm event information is captured and posted by the Event Response resource manager in environment variables that are generated by the Event Response resource manager when an event or a rearm event occurs. The wallevent command can be used as an action that is executed by an Event Response resource. It can also be used as a template to create other user-defined actions.
The following message template is displayed at the consoles of all users who are logged in when an event or a rearm event for which wallevent is a response action occurs:
Broadcast message from <user@host> <tty> at <hh:mm:ss>... <Severity> <Event Type> occurred for the condition <Condition Name> on the resource <Resource Name> of <Resource Class Name> at <Event Time>
