Dial-in telemetry examples

This section contains examples of telemetry subscription requests and responses. The following examples are dumps of protobuf messages from a Python API. Formats may vary across different implementations.

Example 1: Subscribe to a single path

2017-06-05 17:06:13,189 - SENT::SubscribeRequest
subscribe {
  subscription {
    path {
      element: "state"
      element: "router[router-instance=Base]"
      element: "interface[interface-name=test]"
      element: "statistics"
      element: "ip"
      element: "in-packets"
    }
    mode: SAMPLE
    sample_interval: 10000000000
  }
}

  prefix {
    element: "state"
    element: "router[router-instance=Base]"
    element: "interface[interface-name=test]"
    element: "statistics"
    element: "ip"
  }
  update {
    path {
      element: "in-packets"
    }
    val {
      json_val: ‟‟0””
    }
  }
}
