Abstract

Monitoring of Service Level Agreements is a crucial phase of SLA management. In the most challenging case, monitoring of SLA fulfillment is required in (near) real-time and needs to combine performance data regarding multiple distributed services and resources. Currently existing Grid monitoring and information services do not provide adequate on-line monitoring capabilities to fulfill this case. We present an application of Complex Event Processing principles and technologies for on-line SLA monitoring in the Grid. The capabilities of the presented SLA monitoring framework include (1) on-demand definition of SLA metrics using a high-level query language; (2) real-time calculation of the defined SLA metrics; (3) advanced query capabilities which allow for defining high-level complex metrics derived from basic metrics. SLA monitoring of data-intensive grid jobs serves as a case study to demonstrate the capabilities of the approach.
