Configuring Static Telemetry Subscription (IPv4 Collector)

Static telemetry 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 or UDP.

In static telemetry subscription mode, a device initiates a connection to a collector to send data collected.

If the connection is interrupted, the device connects to the collector and sends data again. However, the data sampled when the connection is being established again is lost.
After a master/slave main control board 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 master/slave switchover is lost.

If the device restarts or a master/slave main control board switchover occurs, the system is busy and the CPU usage is high. In this case, you can configure telemetry static subscription for coarse-grained data collection to relieve device load.

Pre-configuration Tasks

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

Configuring a Destination Collector: When you configure static telemetry subscription to the data sampled or a customized event, you need to create a destination group and specify a destination collector to which the data is sent.

Configuring the Data to Be Sampled or a Customized Event: When you configure static telemetry subscription to the data sampled or a customized event, you need to create a sampling sensor group and specify a sampling path and filter criteria.

Creating a Subscription: When you configure static telemetry subscription to the data sampled or a customized event, you need to create a subscription to associate the configured destination group with the configured sampling sensor group so that data can be sent to the collector.

Verifying the Telemetry Configuration: After configuring static telemetry subscription to the data sampled or a customized event, check information about the sampling sensor group, destination group, and subscription.
