Managing Third-Party Event Brokers

Managing Third-Party Event Brokers in VAST Web UI

You can view, add, edit and delete event brokers in cluster settings.

To add an event broker to the cluster:

Go to Settings -> Event Broker.
NOTE: With VAST Cluster 5.4.0-SP3 or earlier, select Settings -> Notifications -> Notification Kafka Brokers.

Click Add a New Event Broker and complete these fields:

Name	Enter a name for the event broker configuration.
Tenant	Select one tenant for which the event broker will be available, or leave the default of All tenants so that the broker is available for all tenants.
Host	Enter the bootstrap URL of the event broker server. You can specify an IP or FQDN. If the Kafka cluster runs multiple event brokers, click +Add to add more hosts. You can add up to five hosts.
Port	Enter a port to communicate with the event broker server. NOTE: Ensure that the hosts are accessible from the VAST cluster's management interface at the specified ports.
Add certificate	This field lets you add or update certificates used for mTLS authentication between the VAST cluster and the event broker. You can select one of the existing set of certificates (those already uploaded to VAST Cluster), or click Create New to open the Event Broker > mTLS certificates dialog where you can enter (paste or upload) a client certificate, a private key and a CA certificate. At a time, only one set of certificates can be assigned to an event broker. Certificates can be shared by multiple event brokers. Unused sets of certificates (those not currently assigned to any event broker) are not deleted from the VMS so that you can reuse them later.
Enforce hostname match between certificate and server	Toggle this option on if you want the cluster to verify that the hostname presented in the server’s certificate matches the server hostname.

Click Add Event Broker.
The newly created event broker configuration is added to the list of event brokers.

To edit or remove an event broker, right-click it and choose Edit or Remove.

Task	Command

Modify an event broker	`eventbroker modify`
