You add an SNMP Trap plug-in when you want to configure vRealize Operations Cloud to log alerts on an existing SNMP Trap server in your environment.
You can provide filtering when you define a Notification using an SNMP Trap destination.
Ensure that you have an SNMP Trap server configured in your environment, and that you know the IP address or host name, port number, and community that it uses.
- In the menu, click Administration and then in the left pane, click Management.
- Click Outbound Settings and click Add.
- From the Plug-In Type drop-down menu, select SNMP Trap Plugin.
The dialog box expands to include your SNMP trap settings.
- Enter an Instance Name.
- (Optional) Click the Use Proxy check box and then select the cloud proxy from the Collector/Group drop-down menu to establish a connection.
Note: You must use a cloud proxy if your SNMP destination host is located outside of AWS.
- Configure the SNMP trap settings appropriate to your environment.
Option Description Destination Host
IP address or fully qualified domain name of the SNMP management system to which you are sending alerts.
Port used to connect to the SNMP management system. Default port is 162.
Text string that allows access to the statistics. SNMP Community strings are used only by devices that support SNMPv1 and SNMPv2c protocol.
User name to configure SNMP trap settings in your environment. If the user name is specified, SNMPv3 is considered as the protocol by the plugin.
If left blank, SNMPv2c is considered as the protocol by the plugin.
Authentication algorithms available are SHA-224, SHA-256, SHA-384, SHA-512.
Privacy algorithms available are AES192, AES256.
Engine ID Engine ID serves as an identifier for the agent. It is used with a hashing function to generate localized keys for authentication and encryption of SNMP v3 messages.
It is mandatory to specify the Engine ID when configuring the SNMP Trap plugin. If you do not add the Engine ID and save the SNMP Trap plugin instance, the field is auto-generated the next time you edit the settings.
- Click Test to validate the connection.
Note: The Community and Username options are mutually exclusive. Define either one of them to avoid an error. If you add a user name, you can optionally define the Authentication Protocol and Authentication Password followed by the Privacy Protocol and Privacy Password. The privacy protocol and its password cannot be defined independent of the authentication protocol and its password.
This instance of the SNMP Trap plug-in is configured and running.
What to do next
When the plug-in is added, configure notifications for receiving the SNMP traps.
