Anemos : An autonomous network monitoring system
Anthony Danalis · 2003
We describe the design and implementation of ANEMOS, an Autonomous NEtwork MOnitoring System. ANEMOS allows network operators and end-users to schedule, perform, and analyze active measurements on several network paths through a Web-based GUI. The measurements can be performed with "off-the-shelf" tools, such as Ping. The current prototype measures end-to-end available bandwidth with Pathload, and round-trip delays and losses with a UDP-based configurable variation of Ping. The measurements are archived using the MySQL database, and they can be visualized using MRTG. A major feature of ANEMOS is that it supports rules, post-processing, and alarm detection. Specifically, the user can form processing rules, correlating measurements of different metrics, paths, and time intervals. These rules are then used to detect changing or alarming conditions in the performance of one or more paths, issuing informative alarms. We illustrate ANEMOS with measurements that resulted from monitoring a few paths in US and Europe.
