ChangeNotification

ChangeNotification indicates a change regarding a hubble peer.

Field Type Label Description
name string Name is the name of the peer, typically the hostname. The name includes the cluster name if a value other than default has been specified. This value can be used to uniquely identify the host. When the cluster name is not the default, the cluster name is prepended to the peer name and a forward slash is added.

Examples: - runtime1 - testcluster/runtime1 | | address | string | | Address is the address of the peer's gRPC service. | | type | ChangeNotificationType | | ChangeNotificationType indicates the type of change, ie whether the peer was added, deleted or updated. | | tls | TLS | | TLS provides information to connect to the Address with TLS enabled. If not set, TLS shall be assumed to be disabled. |

NotifyRequest

TLS

TLS provides information to establish a TLS connection to the peer.

Field Type Label Description
server_name string ServerName is used to verify the hostname on the returned certificate.

ChangeNotificationType

ChangeNotificationType defines the peer change notification type.

Name Number Description
UNKNOWN 0
PEER_ADDED 1
PEER_DELETED 2
PEER_UPDATED 3

Peer

Peer lists hubble peers and notifies of changes.

Method Name Request Type Response Type Description
Notify NotifyRequest ChangeNotification stream Notify sends information about hubble peers in the cluster. When Notify is called, it sends information about all the peers that are already part of the cluster (with the type as PEER_ADDED). It subsequently notifies of any change.
