SNMP Trap Action(s)

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. Login to IT360 console with the Username and Password of an Admin user.

  2. Click the Admin tab in the header pane.

  3. Click Actions under Alarms.

  4. Choose Servers & Applications from the Actions profiles for dropdown. The Action Profile Configuration wizard is displayed.

  5. Click the Add New link under SNMP Trap Action(s). The Create Action : Send Trap of SNMP Version page is displayed. Specify the following details.

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

    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.
