gRPC streaming for Junos Telemetry Interface firewall filter statistics

You can use gRPC interfaces to provision sensors to subscribe to and receive firewall filter telemetry data. If your Juniper Networks device is running a version of Junos OS with the upgraded FreeBSD kernel, you must download the Junos Network Agent package, which provides the interfaces to manage gRPC subscriptions. The package is available on the All Junos Platforms software download URL on the Juniper Networks webpage. Hierarchical policer statistics are included in telemetry data for firewall filters. Use the /junos/system/linecard/firewall/ path to provision a sensor for firewall filter statistics.
