The vC Ops /admin UI allows you to set SMTP and SNMP destination IP addresses, but for some reason you’re only allowed to add one SNMP (or there is some kind of undocumented syntax available). This post describes how to set multiple SNMP trap destinations. Since we need to use the Custom UI, this is only possible if you have the vC Ops Advanced license or higher (available via vRealize Operations Insight, vCloud Suite or vRealize Operations Suite).
Go to the Custom UI -> Admin -> Configure Outbound Alert and click on the small “Add Alert Handler” icon.
Choose “SNMP Trap” in the dropdown and fill in the rest of the information. Make sure the last row is set to “true”. Click the Test button and make sure the test is successful.
Repeat the procedure for your remaining SNMP trap destinations. Now, you have your multiple destinations configured, and all SNMP traps will be sent to both of them.
