Usage guidelines
You must enable the gRPC service before you can configure gRPC service attributes except the PKI domain attribute.
Disabling the gRPC service deletes all gRPC settings.
Examples
# Enable the gRPC service.
<Sysname> system
[Sysname] grpc enable
grpc pki domain
Use grpc pki domain to specify the PKI domain to be used for SSL communication with collectors.
Use undo grpc pki domain to restore the default.
Syntax
grpc pki domain domain-name
undo grpc pki domain
Default
No PKI domain is specified for SSL communication with collectors.
Views

Predefined user roles
network-admin
Parameters
domain-name: Specifies a PKI domain by its name, a case-sensitive string of 1 to 31 characters. For the device to establish gRPC connections to collectors successfully, make sure the PKI domain already exists and has correct certificate and key settings. For more information about PKI domains, see PKI configuration in Security Configuration Guide.
Usage guidelines
To implement SSL communication with collectors, you must specify a PKI domain.
Execute this command before enabling the gRPC service. If you enable the gRPC service before executing this command, this command does not take effect.
Examples
# Specify the PKI domain for SSL communication with collectors and enable the gRPC service.

Parameters
minutes: Specifies the gRPC session idle timeout timer in minutes, in the range of 0 to 30. To disable gRPC sessions from being timed out, set it to 0.
Usage guidelines
If no gRPC packet exchanges occur on the session between a gRPC and the server before the idle timeout timer expires, the device closes the session.
Examples
# Set the gRPC session idle timeout timer to 6 minutes.
<Sysname> system
[Sysname] grpc idle-timeout 6
grpc port
Use grpc port to specify the gRPC service port number.
Use undo grpc port to restore the default.
Syntax

Parameters
port-number: Specifies the gRPC service port number, in the range of 1 to 65535.
Usage guidelines
Changing the gRPC service port number reboots the gRPC service and terminates all gRPC sessions to the gRPC server. If the new port is not available, the system reboots the gRPC service again to use the old port.
Examples
# Set the gRPC service port number to 50052.
<Sysname> system
[Sysname] grpc port 50052
grpc enable

destination-group (subscription view)
Use destination-group to specify a destination group for a subscription.
Use undo destination-group to remove a destination group from a subscription.
Syntax
destination-group group-name
undo destination-group group-name
Default
A subscription does not have a destination group.
Views
Subscription view
Predefined user roles
network-admin
Parameters
group-name: Specifies a destination group by its name, a case-sensitive string of 1 to 31 characters.
Usage guidelines
A subscription binds sensor groups to destination groups. Then, the device pushes data from the specified sensors to the collectors.
The specified destination group must have been created by using the destination-group command in telemetry view.
You can specify a maximum of five destination groups for a subscription.
Examples
# Specify destination group collector1 for subscription A.
<Sysname> system-view
[Sysname] telemetry
[Sysname-telemetry] subscription A
[Sysname-telemetry-subscription-A] destination-group collector1
Related commands
destination-group (telemetry view)
destination-group (telemetry view)
Use destination-group to create a destination group and enter its view, or enter the view of an existing destination group.
Use undo destination-group to delete a destination group.
Syntax
destination-group group-name

Default
No destination groups exist.
Views
Telemetry view
Predefined user roles
network-admin
Parameters
group-name: Specifies the destination group name, a case-sensitive string of 1 to 31 characters.
Usage guidelines
As a best practice, configure a maximum of five destination groups. If you configure too many destination groups, system performance might degrade.
To delete a destination group that is already used by a subscription, you must remove the destination group from the subscription first.
Examples
# Create a destination group named collector1.
<Sysname> system-view
[Sysname] telemetry
[Sysname-telemetry] destination-group collector1
[Sysname-telemetry-destination-group-collector1]

Parameters
group-name: Specifies a sensor group by its name, a case-sensitive string of 1 to 31 characters.
sample-interval: Specifies that the sensor group sample and push data at intervals. If you do not specify this keyword, the sensor group samples and pushes data only when triggered by events.
msec: Specifies the data push interval in milliseconds. To set the data push interval in seconds, do not specify this keyword.
interval: Specifies the data push interval. The value range for this argument differs depending on the unit of interval measurement.
· If you do not specify the msec keyword, the value range is 1 to 86400.
· If you specify the msec keyword, the data push interval must be a multiple of 100 in the range of 100 to 900.
Usage guidelines
Specify the sample-interval interval option for periodic sensor paths and only for periodic sensor paths.
· If you specify the option for event-triggered sensor paths, the sensor paths do not take effect.
· If you do not specify the option for periodic sensor paths, the device does not sample or push data.
The specified sensor group must have been created by using the sensor-group command in telemetry view.
To change the data sampling interval for a sensor group that is already used by a subscription, you must remove the sensor group from the subscription first.
Examples
# Specify sensor group test for subscription A. Set the data sampling interval to 10 seconds.
