Sensor Replacement

...

  • replace the sensor
    You can probably do this with XML field mapping as well, but here is a very simple scripted sensor that works from an SNMP probe payload:
    Code Block
    
/*
 * bw - sensor for SNMP Distribution discovery (Yale SNMP Discovery)
 * 
 * william.west@yale.edu
 */

new DiscoverySensor({
    process: function() {
        //
        // XML should be in var payload (a global)
        var element = XMLUtil.getText(payload, '//unk_111');
        var rows = element.split('\n'); //expecting multiple lines

        current.os         = rows[0];
        current.os_version = rows[1];
    },
        
    type: 'DiscoverySensor'
});
  • list the new sensor in the "Sensors" section of the appropriate probe record
