Keywords Grid Logging
Description The Logging and Bookkeeping service tracks jobs passing through the Grid. It collects important events generated by both the grid middleware components and applications, and processes them at a chosen LB server to provide the job state. The events are transported through secure and reliable channels. Job tracking is fully distributed and does not depend on a single information source, the robustness is achieved through speculative job state computation in case of reordered, delayed or lost events. The state computation is easily adaptable to modified job control flow.
