Abstract

U radu su opisane osnove Espera, procesora za upravljanje složenim događajima, te EPL jezika za obradu događaja. Također su opisane i prednosti korištenja Espera i EPL-a u odnosu na klasične baze podataka. Prikazana su i dva načina za praćenje kvalitete usluge i njihove prednosti i nedostatke. U sklopu praktičnog dijela razvijena je demo aplikacija za praćenje kvalitete usluge. Aplikacija je razvijena u programskom jeziku Javi, koristeći Eclipse razvojno okruženje. Aplikacija za simulaciju događaja koristi Java objekte generirajući ih i šaljući Esper engine-u, koji ih potom prosljeđuje osluškivačkim klasama. Tamo se provlače kroz EPL izraze i ukoliko su zadovoljeni određeni uvjeti, aktiviraju obavijesti/upozorenja/poruke.

Abstract (english)

In this project the basics of Esper, a complex event processing engine and Event Processing Language, EPL have been described. Also here are described the benefits of using Esper and EPL instead of classic databases. Two methods for monitoring the quality of service with their benefits and shortcomings have been demonstrated. Within this practical work a demo application is developed for monitoring the quality of service. The application has been developed in Java, using the Eclipse development environment. The application simulates events using Java objects, generating and sending them to the Esper engine which forwards them to the listener classes. Event streams are wriggled through EPL querys and if they satisfies specific conditions, notices/warnings/messages are activated instantly.
