An Alarms Service for Monitoring Multi-domain Grid Networks

Effective monitoring of multi-domain Grid networks is essential to support large operational Grid infrastructures. Timely detection of network problems is an essential part of this monitoring. In order to detect the problems, access to network monitoring data that exists in multiple organisations is necessary. This paper presents an Alarms Service that supports monitoring of such multi-domain Grid networks. The service allows timely detection of networking problems based on pre-defined, user-configurable conditions. The requirements gathered from real users for monitoring the networks are discussed. The paper shows how multi-organisation data access is resolved with the use of a standards-based access mechanism. The architecture of the Alarms Service is discussed, providing the reasons behind the design decisions where appropriate. A description of the current implementation of the Alarms Service and its deployment is provided.
