Sensor Selection for IT Infrastructure Monitoring
[chapter]
2010
Lecture Notes of the Institute for Computer Sciences, Social Informatics and Telecommunications Engineering
Preserved Fulltext
The selection of a compact, but sufficiently characteristic set of control variables is one of the core problems both for design and run-time complexity. ...
Supervisory control is the main means to assure a high level performance and availability of large IT infrastructures. ...
We use the systematic, well-tunable mRMR algorithm for variable selection. It is also based on mutual information and has been shown to scale well for large problem spaces [10, 11] . ...

For example, a model can be trained on the features designed as system performance metrics, to detect an incident in the system. ...
However, such generated alarms result in a loss of information, such as the actual value of a performance metric that is used to generate the alarms, and other performance metrics that imply bad system ...

Given a detected performance issue and collected system metrics for an online service system, engineers usually need to make great efforts to conduct diagnosis by first identifying performance issue beacons ...
In order to reduce the manual efforts, in this paper, we propose a new approach to effectively detecting performance issue beacons to help with performance issue diagnosis. ...
These approaches fail to detect the metrics of "CPU usage" and "blocking query", which contain diagnosis information in fine granularity. ...

To this end, we have developed an approach to automate the detection of source code refactorings using structural information extracted from the source code. ...
In applying our approach to several versions of four open source projects we find the average Precision and Recall to be over 90%, thus confirming the effectiveness of our detection approach. ...
Several approaches are tailored to detect refactorings in program code. For instance, Dig et al. [2] propose an approach to detect applied refactorings in Java code. ...

Therefore, a continuous monitoring of system attributes and performance metrics provide the raw data for the analysis of problems affecting the performance of the application. ...
Obtained knowledge form the data analysis process helps to find out about the changes in the workloads, faulty components or problems that can cause system performance to degrade. ...
An advantage of a master node approach is to have all system related performance information in one place; therefore, one can analyze the interactions and relation among the metrics at different layers ...

Further to detecting novel examples, we propose an open set active learning approach that allows a robot to efficiently query a user about unknown observations. ...
We show how a deep metric learning classification system can be applied to such open set recognition problems, allowing the classifier to label novel observations as unknown. ...
In addition to detecting observations belonging to N , our system should select the most informative examples in U for labelling by a user. Obtaining a label is referred to as a query. ...
