GXLA a Language for the Specification of Service Level Agreements [chapter]

Badis Tebbani, Issam Aib
2006 Lecture Notes in Computer Science  
In this work we propose GXLA, a language for the specification of Service Level Agreements (SLA).  ...  GXLA represents the implementation of the Generalized Service Level Agreement (GSLA) information model we proposed in a previous work.  ...  Work on the Specification of Service Level Agreements WSLA Web Service Level Agreement IBM2003 WSLA [5] is a good case of study where the steps and the course of the design of a language of specification  ...

SLA-driven adaptive monitoring of distributed applications for performance problem localization

Dusan Okanovic, van Hoorn, Zora Konjovic, Milan Vidakovic
2013 Computer Science and Information Systems  
As a proof-of-concept, DProf was used for adaptive monitoring of a sample distributed application.  ...  DProf uses performance objectives specified in service level agreements (SLAs), along with call tree information, to detect and localize problems in application performance.  ...  The use of GXLA supports an automation of the service management process. WSLA [53] is a language to specify service levels for web services.  ...

A Comprehensive Survey on Intra and Inter Organizational Agreements

Ikbel Guidara, Tarak Chaari, Kaouthar Fakhfakh, Mohamed Jmaiel
2012 2012 IEEE 21st International Workshop on Enabling Technologies: Infrastructure for Collaborative Enterprises  
In fact, using agreements at different layers of SOA gives a clear specification and control of the agreed service levels between different stakeholders involved in the composition.  ...  In this paper, we give a survey on intra and inter organizational agreements for enterprise collaborations.  ...  This language presents the advantage of being easily extended and domain independent specification. WSOL [9] is the most used language for the description of service offerings.  ...

Mapping of Service Level Objectives to Performance Queries

Jürgen Walter, Dušan Okanović, Samuel Kounev
2017 Proceedings of the 8th ACM/SPEC on International Conference on Performance Engineering Companion - ICPE '17 Companion  
The concept of service level agreements (SLAs) defines the idea of a reliable contract between service providers and their users.  ...  SLAs provide information on the scope, the quality and the responsibilities of a service and its provider. Service level objectives (SLOs) define the detailed, measurable conditions of the SLAs.  ...  by the Research Group of the Standard Performance Evaluation Corporation (SPEC).  ...

A Domain-Specific Language for Service Level Agreement Specification

Renata Vaderna, Zeljko Vukovic, Dusan Okanovic, Igor Dejanovic
2015 The 7th International Conference on Information Technology   unpublished
DProfLang is a domain specific language for defining SLAs, that are both human and machine readable.  ...  On the other hand, it would be beneficial if it is human readable, too. This way, it is easier to perform configuration and maintenance of monitoring subsystem.  ...  ACKNOWLEDGMENT The research presented in this paper was supported by the Ministry of Science and Technological Development of the Republic of Serbia, grant III-44010, Title: Intelligent Systems for Software  ...
