# Example parser for the JSON format history stats output of grpcurl
|
|
# for the gRPC service provided on a Starlink user terminal.
|
|
#
|
|
# Expects input as from the following command:
|
|
# grpcurl -plaintext -d {\"get_history\":{}} 192.168.100.1:9200 SpaceX.API.Device.Device/Handle
|
|
#
|
|
# This script examines the most recent samples from the history data
|
|
# and computes several different metrics related to packet loss. By
|
|
# default, it will print the results in CSV format.
