grpc cpu-usage max-percent
Use grpc cpu-usage max-percent to set the maximum CPU usage for gRPC.
Use undo grpc cpu-usage max-percent to restore the default.
Syntax
grpc cpu-usage max-percent percentage
undo grpc cpu-usage max-percent
Views
System view
Default
No CPU usage limit is set on gRPC.
Predefined user roles
network-admin
Parameters
percentage: Sets the maximum CPU usage for gRPC, in percentage. The value range is 1 to 50.
Usage guidelines
gRPC data sampling is CPU intensive. To prevent gRPC from negatively affecting other services,
limit its maximum CPU usage. If the specified maximum CPU usage is exceeded during data
sampling, gRPC suspends data sampling until after its CPU usage drops below the specified limit.
If you execute this command multiple times, the most recent configuration takes effect.
Examples
# Set the maximum CPU usage for gRPC to 39%.
<Sysname> system-view
[Sysname] grpc cpu-usage max-percent 39
grpc enable
Use grpc enable to enable the gRPC service.
Use undo grpc enable to disable the gRPC service.
Syntax
grpc enable
undo grpc enable
Default
The gRPC service is disabled.
Views
System view
Predefined user roles
network-admin
Usage guidelines
You must enable the gRPC service before you can configure gRPC-related settings.
7
Disabling the gRPC service deletes all gRPC-related settings.
Examples
# Enable the gRPC service.
<Sysname> system
[Sysname] grpc enable
grpc pki domain
Use grpc pki domain to specify the PKI domain for secure gRPC connections to 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 secure gRPC connections to collectors.
Views
System view
Predefined user roles
network-admin
Parameters
domain-name: Specifies a PKI domain by its name, a case-insensitive string of 1 to 31 characters.
Usage guidelines
By default, the gRPC connection between the device and a collector does not provide data
encryption service or require authentication. After you specify a PKI domain, the device and the
collector will use TLS for data encryption and bidirectional certificate-based authentication to
improve communication security.
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
configuration, see Security Configuration Guide.
Executing this command reboots the gRPC service and closes all gRPC connections to collectors. In
dial-in mode, the collectors must re-initiate the connections. In dial-out mode, the device will
automatically re-initiate the connections.
Examples
# Specify the PKI domain for secure gRPC connections to collectors.
<Sysname> system-view
[Sysname] grpc pki domain grpc_test
gRPC dial-in mode commands
grpc idle-timeout
Use grpc idle-timeout to set the gRPC session idle timeout timer.
Use undo grpc idle-timeout to restore the default.
8
Syntax
grpc idle-timeout minutes
undo grpc idle-timeout
Default
The gRPC session idle timeout timer is 5 minutes.
Views
System view
Predefined user roles
network-admin
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 log dial-in gnmi

Views
System view
Predefined user roles
network-admin
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 disconnects all sessions
established between the gRPC server and its gRPC clients. The gRPC clients must reinitiate the
sessions.
If the specified port number is not available (for example, the port number is already used), the gRPC
service reboots to use the original port number.
If you execute this command multiple times, the most recent configuration takes effect.
Examples
# Set the gRPC service port number to 50052.
<Sysname> system
[Sysname] grpc port 50052

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 cannot use a destination group in both a gRPC subscription and a gNMI subscription.
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

Parameters
group-name: Specifies the destination group name, a case-sensitive string of 1 to 31 characters.
12
Usage guidelines
As a best practice, configure a maximum of five destination groups. Configuring too many
destination groups might degrade the system performance.
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.

Usage guidelines
The effective sampling interval for a sensor path is the higher one between the following interval
settings:
The minimum sampling interval displayed in the Min Interval(ms) field for that sensor path.
The sampling interval set for the sensor group that contains the sensor path by using the
sensor-group command in subscription view.
This command displays sensor path information in the following order:
Periodic sensor paths that has a predefined minimum sampling interval.
Periodic sensor paths that use the default minimum sampling interval. These paths are
collectively displayed as default-interval paths in one entry.
Examples
# Display sensor paths that have the minimum sampling interval.
<Sysname> display telemetry sensor-path

domain-name
Use domain-name to add the domain name of an IPv4 collector to a destination group.
Use undo domain-name to remove the domain name of an IPv4 collector from a destination
group.
Syntax
domain-name domain-name [ port port-number ] [ tls ]
undo domain-name domain-name [ port port-number ] [ tls ]
Default
A destination group does not contain IPv4 collectors.
Views
Destination group view
Predefined user roles
network-admin
Parameters
domain-name: Domain name mapped to the IPv4 address of a collector. It can be a
case-insensitive string of 1 to 253 characters and can contain letters, digits, hyphens (-),
underscores (_), and dots (.).
port port-number: Specifies the service port number on which the collector receives data. The
value range is 1 to 65535 and the default is 50051. To have the collector receive data, make sure the
specified service port number is the same as the one used on the collector.
tls: Enables Transport Layer Security (TLS) to encrypt the gRPC connection between the device
and the specified collector. The device will then use a root TLS certificate that came with it for
encryption. By default, the gRPC connections established by the device are unencrypted.
Usage guidelines
If you specify collectors by their domain names, you must configure DNS to make sure the device
can translate the domain names of the collectors to IPv4 addresses. For more information about
DNS, see Layer 3IP Services Configuration Guide.
14
To view domain name and IP address mappings, use the display dns host command. If a
domain name maps to multiple IP addresses, the device pushes data to the first reachable IP
address.
To add multiple collectors, repeat this command.
A collector is uniquely identified by a combination of the domain name and port number
elements. One collector must have a different element in this combination.
If you execute this command multiple times to change the TLS enabling state for a collector, the
most recent configuration takes effect.
A destination group can have a maximum of five collectors.
You can enable TLS encryption globally by executing the grpc pki domain command in system
view or enable collector-specific TLS encryption by specifying the tls keyword when you specify
the collector. For a collector, the setting in system view has higher priority than the collector-specific
setting.
To modify the collector configuration for a destination group that is already used by a subscription,
you must remove the destination group from the subscription first.
Examples
# Add the IPv4 collector at sample.com to destination group collector1.

Parameters
dscp-value: Specifies the DSCP value for packets sent to collectors, in the range of 0 to 63.
Usage guidelines
A greater DSCP value represents a higher priority.
15
If you execute this command multiple times in the same view, the most recent configuration takes
effect.
Examples
# Set the DSCP value for packets sent to collectors to 12 for subscription A.

grpc log dial-out
Use grpc log dial-out to enable gRPC logging in dial-out mode.
Use undo grpc log dial-out to disable gRPC logging in dial-out mode.
Syntax
grpc log dial-out { all | { event | sample }* }
undo grpc log dial-out { all | { event | sample }* }
Default
In dial-out mode, gRPC logging is disabled.
Views
System view
Predefined user roles
network-admin
Parameters
all: Specifies all data collection types.
event: Specifies event-triggered data collection.
sample: Specifies periodical data collection.
Usage guidelines
To identify gRPC issues, enable gRPC data collection logging in dial-out mode.
This command generates gRPC data collection logs in dial-out mode and sends them to the
information center. With the information center, you can configure log destinations and output rules.
For more information about the information center, see Network Management and Monitoring
Configuration Guide.
gRPC logging in dial-out mode is unavailable for gNMI subscriptions.
If you execute this command multiple times, the most recent configuration takes effect.
Examples
# Enable gRPC logging for periodical data collection in dial-out mode.
<Sysname> system
[Sysname] grpc log dial-in gnmi get
ipv4-address
Use ipv4-address to add an IPv4 collector to a destination group.
16
Use undo ipv4-address to remove an IPv4 collector from a destination group.
Syntax
ipv4-address ipv4-address [ port port-number ] [ tls ]
undo ipv4-address ipv4-address [ port port-number ] [ tls ]
Default
A destination group does not have IPv4 collectors.
Views
Destination group view
Predefined user roles
network-admin
Parameters
ipv4-address: Specifies the IPv4 address of the collector.
port port-number: Specifies the listening port of the collector, in the range of 1 to 65535. The
default is 50051.
tls: Enables Transport Layer Security (TLS) to encrypt the gRPC connection between the device
and the specified collector. The device will then use a root TLS certificate that came with it for
encryption. By default, the gRPC connection between the device and a collector is unencrypted.
Usage guidelines
To add multiple collectors to a destination group, execute this command multiple times.
A collector is uniquely identified by a combination of the IP address and port number elements. One
collector must have a different element in this combination.
If you execute this command multiple times for a collector, the most recent configuration takes effect.
You can specify a maximum of five collectors for a destination group.
You can enable TLS encryption globally by executing the grpc pki domain command in system
view or enable collector-specific TLS encryption by specifying the tls keyword when you specify
the collector. For a collector, the setting in system view has higher priority than the collector-specific
setting.
To modify the collector configuration for a destination group that is already used for a subscription,
you must remove the destination group from the subscription first.
Examples
# Add a collector that uses IPv4 address 192.168.21.21 and the default port number to destination
group collector1.
<Sysname> system-view
[Sysname] telemetry
[Sysname-telemetry] destination-group collector1
[Sysname-telemetry-destination-group-collector1] ipv4-address 192.168.21.21

ipv6-address
Use ipv6-address to add an IPv6 collector to a destination group.
17
Use undo ipv6-address to remove an IPv6 collector from a destination group.
Syntax
ipv6-address ipv6-address [ port port-number ] [ tls ]
undo ipv6-address ipv6-address [ port port-number ] [ tls ]
Default
A destination group does not have IPv6 collectors.
Views

Parameters
ipv6-address: Specifies the IPv6 address of the collector. The IPv6 address cannot be a
link-local address. For more information about link-local addresses, see IPv6 basics configuration in
Layer 3IP Services Configuration Guide.
port port-number: Specifies the listening port of the collector, in the range of 1 to 65535. The
default is 50051.
tls: Enables Transport Layer Security (TLS) to encrypt the gRPC connection between the device
and the specified collector. The device will then use a root TLS certificate that came with it for
encryption. By default, the gRPC connection between the device and a collector is unencrypted.
