[edit dynamic-profiles profile-name]

Description

Enable telemetry collection of subscriber statistics and queue statistics.

Include the subscriber-statistics statement to enable the export of subscriber statistics through telemetry. When this statement is configured, you must also include the actual-transit-statistics statement at the [edit dynamic-profiles profile-name interfaces interface-name unit unit-name} hierarchy level to enable subscriber-statistics.

Include the queue-statistics statement to instruct the statistics infrastructure to collect queue statistics for dynamic interfaces or interface-sets queue-statistics and enable export via Junos Telelemetry Interface (JTI).

The profile variable $junos-interface-name” and “$junos-interface-set-name” are generated from the corresponding device, unit and interface-set elements in the interfaces stanza at profile instantiation time. Using these derived variables is a convenient way to configure telemetry behavior for the interface or interface-set without the need to mimic the specific configuration in the interfaces stanza.

After telemetry for these statistics is enabled, they are eligible for export through a collector subscription.

For information about subscribing to the statistics through an external collector, see Configure a NETCONF Proxy Telemetry Sensor in Junos. For information about supported sensors for subscriber statistics and queue statistics, see Guidelines for gRPC and gNMI Sensors (Junos Telemetry Interface).

Options

subscriber-statistics	Enable the export of interface meta-data and export of subscriber accurate statistics. When this statement is configured, you must also include the `actual-transit-statistics` statement at the [`edit dynamic-profiles profile-name interfaces interface-name unit unit-name`] hierarchy level.
queue statistics interface “$junos-interface-name”	Enable the export of interface meta-data and interface queue statistics. The profile variable `$junos-interface-name”` is generated from the corresponding device, unit and interface elements in the interfaces stanza at profile instantiation time.
queue statistics interface-set “$junos-interface-set-name”	Enable the export of interface-set meta-data and interface-set queue statistics. The profile variable `“$junos-interface-set-name”` is generated from the corresponding device, unit and interface-set elements in the interfaces stanza at profile instantiation time.
refresh `rate`	Override the default internal queue statistics collection interval. If dynamic interfaces and interface-sets are created as a result of multiple dynamic profiles, each with their own refresh intervals, the smallest interval for each object type (interface or interface-set) is used to poll queue statistics for that object type. The default is 900 seconds. Range: 300 seconds (5 minutes) to 86,400 seconds (24 hours)
queue “`queue-set`”	Specify the set of queues for which queue-statistics will be exported. The queue set is a comma delimited string of integers. The default is all queues (`0,1,2,3,4,5,6,7`) are eligible for export. Range: 0 to 7
