Email Notifier Adapter example: Modifying the mail-filter.asl script

To customize an Email Notifier Adapter, add the sentByCustom variable to the mail-filter.asl script. In addition, you need to modify the filter script to send emails when a notification is cleared:

1. Using sm_edit, open the mail-filter.asl script. Open the file using the following command:

   t BASEDIR/smarts/bin>sm_edit rules/notifier/mail/
   mail-filter.asl s
   

2. Add the following line for the sentByCustom variable to the end of the script (as shown below in bold type).

   By default, when a network problem is resolved and a CLEAR notification is received, an email is not sent to the administrators involved in the repair. Within the mail-filter.asl script, you can use the filterMe variable to indicate whether or not you want an email to be delivered when a notification is cleared (when the problem is resolved).

   To have emails sent on CLEAR notifications, change the filterMe = TRUE Boolean value to FALSE (as shown in bold type):

   ...
   START() {
   /* 
    * Filter cleared events.
    */
   OMIT_CLEAR_EVENTS() filter { 
       (currentEvent->icType == "CLEAR" || currentEvent->icType 
        == "NL_CLEAR")
   } do {
                      currentEvent->filterMe = FALSE;
   currentEvent->sentByCustom = TRUE;
   }
    }
   

3. Save the modified script. The sm_edit utility automatically saves the script to the BASEDIR/smarts/local/rules/notifier/mail directory.
