Leveraging Complex Event Processing for Grid Monitoring [chapter]

Bartosz Balis, Bartosz Kowalewski, Marian Bubak
2010 Lecture Notes in Computer Science  
We present a monitoring system which uses CEP technologies to expose monitoring information as queryable data streams. We study an example use case -monitoring for job rescheduling.  ...  However, for some scenarios querying real-time streams of monitoring information would be extremely useful.  ...  We have found that the EPL stream query language provides expressiveness sufficient to support complex scenarios, not achievable through traditional database query languages.  ...

Workload Classification & Software Energy Measurement for Efficient Scheduling on Private Cloud Platforms [article]

James W. Smith, Ian Sommerville
2011 arXiv   pre-print
In this paper we discuss the effect of different workloads on server power consumption in a Private Cloud platform.  ...  We then use this insight to develop CloudMonitor, a software utility that is capable of >95% accurate power predictions from monitoring resource consumption of workloads, after a "training phase" in which  ...  In this case the PDU acts as another agent, providing real time data in response to queries.  ...

Event Stream Processing with Multiple Threads [article]

Sylvain Hallé and Raphaël Khoury and Sébastien Gaboury
2017 arXiv   pre-print
In this paper, we present an extension to the BeepBeep 3 event stream engine that allows the use of multiple threads during the evaluation of a query.  ...  Compared to the previous, single-threaded version of the BeepBeep engine, the allocation of just a few threads to specific portions of a query provides dramatic improvement in terms of running time.  ...  Indeed, the prospect of parallel processing of temporal constraints in general, and LTL formulae in particular, is held back precisely because of the sequential nature of the properties to verify: since  ...

Towards a Software Framework for the Autonomous Internet of Things

Marco E. Perez Hernandez, Stephan Reiff-Marganiec
2016 2016 IEEE 4th International Conference on Future Internet of Things and Cloud (FiCloud)  
As consequence, we observe a trend towards a data-feeder architecture in which "smart objects" are simple data gatherers and senders.  ...  We propose a framework and architecture for the development of IoT applications where smart objects exhibit autonomy in regards platforms and human users.  ...  Each SO has a local path where implementation of the services are stored. On SO booting, the management functions query and generate knowledge items (documents) with the interfaces for each service.  ...

Optimizing the Performance-Related Configurations of Object-Relational Mapping Frameworks Using a Multi-Objective Genetic Algorithm

Ravjot Singh, Cor-Paul Bezemer, Weiyi Shang, Ahmed E. Hassan
2016 Proceedings of the 7th ACM/SPEC on International Conference on Performance Engineering - ICPE '16  
We evaluate our approach by conducting a case study of Spring PetClinic and ZK. We find that our approach finds near-optimal configurations in 360-450 seconds for Pet-Clinic and in 9-12 hours for ZK.  ...  However, determining the set of optimal configuration options is a challenging task.  ...  Using a single query with multiple joins is generally faster than using separate queries when all information returned by the query is used.  ...
