Types

type EventMsg

type EventMsg struct {
	Name      string                 `json:"name,omitempty"`
	Timestamp int64                  `json:"timestamp,omitempty"`
	Tags      map[string]string      `json:"tags,omitempty"`
	Values    map[string]interface{} `json:"values,omitempty"`
	Deletes   []string               `json:"deletes,omitempty"`
}

EventMsg represents a gNMI update message, The name is derived from the subscription in case the update was received in a subscribeResponse the tags are derived from the keys in gNMI path as well as some metadata from the subscription.
