Sending Trap

Introduction: 

This section is common to all the editions of IT360 - Professional Edition, Enterprise Edition (Probes) and MSP Edition (Probes).

There are certain circumstances, when some Manager Applications also need to be intimated about occurrance of fault in the Servers or Applications, being monitored. In such cases, the alerts can be sent as traps to the Manager applications, and they can be viewed by any standard SNMP Manager, such as Trap Viewer, HP Openview, IBM Tivoli etc. The supported versions of SNMP Trap are SNMPv1 and SNMPv2c.

Creating Trap Action:

To configure an alert as a trap and send it as an action, follow these steps;

1. Go to 'Admin -> Servers & Applications -> Actions' [or] 'Admin -> Alarms -> Actions'.

2. Click 'Create Trap Action' link. This opens the 'Create Send Trap action' page.

3. Select the SNMP trap version (v1/ v2c) from the combo box.

4. If you select the SNMP trap version v1, specify the following details;

   1. The 'Display Name' for the action.

   2. The 'Destination Address' or the manager application 'Host Name', to which the trap is to be sent.

   3. The 'Destination Port Number', where the manager host is running.
      
      The following are the details required to be filled for a trap PDU: 

   4. The 'Object ID' (OID/Object Identifier) of the management object of a MIB.

   5. The 'Community' for the trap.

   6. The 'Message (Varbinds)', which will be sent as trap varbinds. The message can be enhanced by using Replaceable Tags.
      
      Note : Multiple Varbinds can be specified by having multiple ObjectIDs and their values as comma separated in "ObjectID" and " Message (Varbinds) " field respectively. For e.g., you can give ObjID1, ObjID2, ObjID3 in the ObjectID field to represent 3 Object IDs and correspondingly give ObjValue1, $RCAMESSAGE (the root cause message will be passed through the replaceable tag - $RCAMESSAGE), ObjValue3 etc., in the varbinds field to specify the values. ObjID1 and ObjValue1 will be passed as varbinds, same is the case with the other varbinds.

   7. Choose the 'Message Format' as 'Plain Text' or 'HTML'.

   

   8. Select the 'Generic Type' of trap PDU from the combo box.

   9. Specify the 'Enterprise OID' for the trap. You can also use the MIB Browser to provide the OID. In case, you want to upload a new MIB, then use the Upload File option.

   

   Note: If you choose the 'Generic Type' as 'enterpriseSpecific', then you should provide the 'Enterprise Specifc Type' and then specify the 'Enterprise OID', as shown in the below screenshot:
