Setting up near real-time discovery of VMware events
To set up near real-time discovery of VMware events, configure the VMware vCenter Server SNMP settings with the Management Server address as the receiver URL. The Management Server receives the updates when you add the VMware vCenter Server to the Management Server.
The VMware vCenter Server generates SNMP traps for the following events:
-
When a virtual machine's state changes - powered on, powered off, and suspended.
-
When any other virtual infrastructure-related changes are detected. For example, when a virtual machine is created, migrated, or renamed.
The vCenter Server sends the SNMP trap to the Management Server. The SNMP trap contains the information of the virtual machine state, and it is used to update the Management Server database.
Note: SNMP version 1 (SNMPv1) and version 2 (SNMPv2) are supported.
The Veritas InfoScale Operations Manager component of near real-time discovery is
xtrapd. It runs as a daemon on Linux and as a service on Windows operating system. xtrapd detects the SNMP trap that is sent from the VMware vCenter Server, updates the virtual machine records in the Veritas InfoScale Operations Manager database, and subsequently the Management Server console is updated with the latest state of the virtual machine.
To set up the near real-time discovery of VMware events, complete the following steps:
Table: Setting up near real-time (NRT) discovery of VMware events
| Step | Action | Description |
|---|---|---|
| Step 1 | Provide Management Server details in the VMware vCenter Server console. | Provide information to configure Management Server as the SNMP trap receiver. Also configure the alarm to send the SNMP traps when the state of the virtual machine changes. |
| See Configuring the VMware vCenter Server to generate SNMP traps . | ||
| Step 2 | Add VMware vCenter Server to Management Server. | When you add a VMware vCenter Server to Management Server, the xtrapd daemon on the Management Server starts accepting SNMP traps from the specified VMware vCenter Server. |
| See Adding a virtualization server . | ||
| Note: If you have not configured the VMware vCenter Server before adding it to the Veritas InfoScale Operations Manager domain, a warning message is displayed. It does not affect the vCenter Server discovery. However, near real-time discovery of VMware events is not functional. If you want to enable the discovery, you need to first configure the VMware vCenter Server, and then refresh the VMware vCenter Server configuration in the Management Server console. |
Using VMware vCenter Server console: Using the Management Server console:
By default, near real-time discovery of VMware events is enabled. To disable it, you need to remove the Management Server as the SNMP receiver in the VMware vCenter Server and refresh vCenter configuration in Veritas InfoScale Operations Manager Management Server.
