Network performance monitoring and troubleshooting is a critical but challenging task in data center management. Although many solutions have been proposed in the past decades, it is still difficult to deploy them in the real world because of the expensive cost. In this work, we propose LMon, a network measurement and fault localization system for facilitating long-term maintenance of datacenter networks. LMon employs a lightweight network monitoring tool based on packet pair technique, which supports bi-directional monitoring only on one end host without replacing any device. Moreover, the least measurement deployment policy introduces very small overhead to the network. LMon has been deployed to our production data center on a scale of 50 racks and 500 servers for months. The running experience confirms the efficiency of LMon and points out the future direction of improvement.
