######################################################################
#
# Equivalent script to parseJsonHistory.py, except integrating the
# gRPC calls, instead of relying on separatate invocation of grpcurl.
#
# 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.
