  Network performance monitoring collects heterogeneous data suchas network
flow data to give an overview of network performance,and other metrics,
necessary for diagnosing and optimizing servicequality. However, due to
disparate and heterogeneity, to obtainmetrics and visualize entire data from
several devices, engineershave to log into multiple dashboards.In this paper we
present NetGraf, a complete end-to-end networkmonitoring stack, that uses
open-source network monitoring toolsand collects, aggregates, and visualizes
network measurements on asingle easy-to-use real-time Grafana dashboard. We
develop a novelNetGraf architecture and can deploy it on any network testbed
suchas Chameleon Cloud by single easy-to-use script for a full view ofnetwork
performance in one dashboard.This paper contributes to the theme of automating
open-sourcenetwork monitoring tools software setups and their usability
forresearchers looking to deploy an end-to-end monitoring stack ontheir own
testbeds.
