If you would like VitalSigns to send SNMP traps to another system, you need to complete 3 steps:
1) Enable SNMP Traps
2) Create an Alert Definition which sends traps in response to detected events
3) Import the VitalSigns MIB into the external system
Step 1: Enable SNMP Traps
- You first need to tell VitalSigns where to send the traps. This is done in the Configurator, Alerts, Alert Settings:
- Check the box Enable SNMP traps and enter the host name of the computer that will be listening for trap messages. For instance, if you want to send the traps to HP Openview, enter hostname of the HP Openview machine here.
Step 2: Create an Alert Definition which sends Traps
Next go to Configurator, Alerts, Alert Definitions. Either create a new alert or edit an existing one. In the section Hours & Destinations, select SNMP Trap as the Alerting Mechanism.

Step 3: Import the MIB into the other system
SNMP Traps are not human-friendly. The consist largely of very long numbers., such as 1.3.6.1.4.1.26062.1.1.1.9. To keep it all straight, the computer which receives these numbers needs a file to decode it. For example, the number segment 26062 which appears in the middle of the trap uniquely identifies the trap as being from VitalSigns. The file which allows a receiving system to decode a trap is called a 'MIB' and the file is located in the \program files(x86)\VitalSignsPlus folder. Look for a file called VITALSIGNS-MIB.mib and copy this file to your other machine (for example HP Openview). Every system has a different process for importing a MIB so the best solution is to simply Google for 'import MIB productname' such as 'import MIB HP Openview' and follow the instructions found.

You may see two MIB files VITALSIGNS-MIB.mib and VITALSIGNS-MIB1.mib in the VitalSignsPlus folder. Select the smaller ( VITALSIGNS-MIB.mib) file. |

What is in a trap? The trap basically sends five values to the other system. These represent Alert Type, Server Type, Server Name, Details, and Date |
