There are actually three add-ons which may be configured with the M&C software to notify operators if new event messages have been issued by the system. Notification may be through a serial interface of the MNC server or send by E-mail or passed to a script. Event notification add-ons are included in the sat-nms MNC service, not in the backend service.
A notification add-on is activated by setting the key server.addon in the file vlc.properties either to EventToSerial, EventToMail or to EventToScript. All particular settings for the selected notification add-on are defined in a separate configuration file. A file specified by the keyword rules has to be created with the filter rules which messages are to be forwarded and which not.
Event To Serial Notification
server.addon=EventToSerial
The event to serial notification add-on sends event messages through a serial RS232 interface. This interface may be connected to a separate unit which sends SMS messages or teletype messages from this information. Page Event To Serial Notification describes this feature in detail.
Event To Mail Notification
server.addon=EventToMail
The event to mail notification add-on sends event messages as e-mail notifications to one or more recipients. Page Event To Mail Notification describes this feature in detail.
Event To Script Notification
server.addon=EventToScript
The event to script notification add-on sends event messages via standard-out to a script located on the MNC server. Page Event To Script Notification describes this feature in detail.
