This Trap notification defines an network event detected by the CODIMA Express monitor alarm system. The payload is as follows. alarmMessage: A textural description of an event. alarmLayer: The OSI Network Layer associated with this event. alarmTopProtocol: The upper OSI Network layer protocol associated with this event For example: SNMP, FTP. alarmBaseProtocol: The lower OSI Network layer protocol associated with this event. For example: IP, IPX. alarmCode: The Code number associated with this event. alarmFunction: A range of Functions that apply to a particular Alarm Group. For example: The Discovered Group covers the application of discovering the MAC addresses, IP addresses and Unit Type information logged. alarmGroup: Alarm Groups are used to group a specific range of event reports, each group has a range of functions. The grouping is generally based on either a protocol component, a network type or the application associated with the event report. For example:- The Discovered Group covers the application of discovering the MAC addresses, IP addresses and Unit Type information logged. alarmUnitType: The unit type is the type of the device that generated this event, e.g. Bridge, Workstation, File Server. alarmClass: The severity of this alarm. One of the four following levels are included: Critical: The highest priority level alarm log report classification (usually applied to SNMP reports which are to be converted into Traps). Alarm: The second highest priority level alarm log report classification (usually applied to potentially dangerous situations such a breaches in statistical thresholds or Echo and Activity Test Failures). Warning: The second lowest priority level alarm log report classification (usually applied to most of the reports associated with the Expert System). Event: The lowest priority level alarm log report classification (usually applied to the logging of useful information, such as the discovery of an IP address or a new Node on the Network). alarmTime: The UTC time of when this event was issued. The value is in the format 'dd/mmm/yyyy hh:mm:ss'. The time (hh:mm:ss) is expressed as a 24-hour clock. The date (dd/mmm/yyyy) format uses 3 letter abbreviations for the month. An example is 05/Jun/2003 14:58:15.
