The lower the MTTR the higher the availability. A significant portion of the MTTR is spent in the detection and localization of the cause of the failure. One possible method that may provide good results in the root-cause analysis of application failures is run-time profiling. The major drawback of run-time profiling is the performance impact. In this paper we describe two algorithms for selective and adaptive profiling of web-based applications. The algorithms make use of a dynamic profiling interval and are mainly triggered when some of the transactions start presenting some symptoms of performance anomaly. The algorithms were tested under different types of degradation scenarios and compared to static sampling strategies. We observed through experimentation that the pinpoint of performance anomalies, supported by the data collected using the adaptive profiling algorithms, stills timely as with full-profiling while the response time overhead is reduced in almost 60%. When compared to a non-profiled version the response time overhead is less than 1.5%. These results show the viability of using run-time profiling to support quickly detection and pinpointing of performance anomalies and enable timely recovery.","PeriodicalId":258309,"journal":{"name":"2011 IEEE 10th International Symposium on Network Computing and Applications","volume":"250 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-08-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116166158","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While the typical target tracking approaches are based on movement prediction, we only assume a knowledge of some maximal speed of the target during certain time-intervals. This, in turn, restricts its whereabouts to a disk-bound area throughout such intervals. In such settings, we seek to determine a sensor cover, a subset of all the nodes that need to be awake, which ensures that the target can be detected during the given epoch. Towards this, we propose sensor-cover selection methodologies, Greedy Uncertain Moving Object coverage sensor set selection (GUMO) and PAttern Based coverage sensor set selection (PAB). GUMO is a heuristic maximizing the coverage gain at each step, while PAB is an approach based on optimal deployment pattern of sensor nodes achieving coverage of the disk area bounding the target's whereabouts. We conduct extensive simulations to evaluate the performance of the algorithms, and the results reveal that GUMO and PAB not only provide substantial energy saving due to reduction in the communications involved in selecting tracking participant-nodes and principal(s), while assuring a bounded error on the target's location.","PeriodicalId":258309,"journal":{"name":"2011 IEEE 10th International Symposium on Network Computing and Applications","volume":"86 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-08-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127543763","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
