Configuring the VMware vCenter Server to generate SNMP traps
Provide the following information to configure the vCenter Server to generate SNMP traps:
-
Using the vCenter Server console, configure the Management Server as the SNMP trap receiver.
In the Home page of vSphere Client, select vCenter Server Settings and then select SNMP configuration. Enable one of the SNMP receivers and enter the details as follows:
| Field | Description |
|---|---|
| Receiver URL | Provide the host name of the Management Server which will be connected to the VMware vCenter Server. VMware vCenter Server sends the SNMP traps to this Management Server. |
| Also, configure port 162 as the SNMP port. Ensure that port 162 is not used by any other application in Veritas InfoScale Operations Manager Management Server. | |
| Note: For a Windows Management Server configured in high availability (HA) environment, provide the virtual IP address of the Management Server HA setup. | |
| Community String | Provide community string. SNMP versions v1 and v2 are supported. |

Configure alarm for generating SNMP traps when a virtual machine state changes or any virtual infrastructure-related change occurs.
It includes adding alarm to monitor the changes related to virtual machine state and vCenter Server infrastructure, and then adding the appropriate action (for example, send a notification trap).
-
In the Home page of the VMware vSphere Client, select Hosts and Clusters and right-click on the VMware vCenter Server, data-center or an individual virtual machine to set the alarm. You can set the alarm at an individual virtual machine level, at the data center level, or at the entire VMware vCenter Server level. It is recommended to set it at the VMware vCenter Server level.
