Configuring Telemetry Static Subscription

Configuring Telemetry Static Subscription

Telemetry static subscription indicates that a device functioning as a client initiates a connection to a collector functioning as a server to send data collected.

Usage Scenario

The controller uses commands to configure devices that support Telemetry, subscribe to data sources, and collect data. The protocol used to send data can be gRPC.

If the connection between a device and the collection is interrupted, the device connects to the collector and sends data again. However, the data sampled when the connection is being re-established is lost.

After an active/standby switchover is performed or the system saves Telemetry service configurations and restarts, the Telemetry service reloads its configurations and continues to run. However, the data sampled during the restart or active/standby switchover is lost. This poses high pressure on devices. Therefore, Telemetry static subscription is often used for coarse-grained data collection.

Pre-configuration Tasks

Before configuring Telemetry static subscription, configure a static or dynamic routing protocol so that devices can communicate at the network layer.
