Machine-generated log data is valuable in locating causes of various hardware and software failures. The information derived from it can provide feedback in improving system architecture, reducing system degradation, and improving up-time. Recently, businesses have started using this log data for deriving business insight. Using a fault-tolerant architecture, Flume is a distributed, service for efficiently collecting, aggregating, and moving large amounts of log data. In this article, we will learn how to deploy and use Flume with a Hadoop cluster and a simple distributed web service.

Thermoelectric and solar power generation are two promising alternative energy  solutions for the military. Power generation devices based on these two technologies aid the military by lightening soldiers' loads and allowing them to  carry fewer batteries and more equipment. Since these technologies use renewable  energy sources, Soldiers are also spared the nuisance of having to constantly  resupply. Thermoelectric power generates electricity from any adventitious  source of heat, while solar cells employ sunlight to do the same. Both  technologies are currently subject to extensive research to improve efficiency,  utility, and cost. Although they both operate on renewable energy sources, each  technology functions at a different temperature range. Thermoelectric devices  run on low temperatures, generally below 1000 K, while solar cells require  temperatures equivalent to those of the sun. Thermoelectric and solar power  generators complement each other since they are capable of producing electricity  from disparate sources. Solar produces highly efficient power during daytime but fails in darkness. Thermoelectrics can produce electricity with lower efficiency  but dramatically more sources of heat are available for thermoelectric power generation, enabling full diurnal operation. This report discusses measurements  of the properties and efficiency of a thermoelectric device and a solar cell.

With emphasis on Apache Giraph and the GraphLab framework, this article introduces and compares open source solutions for processing large volumes of graph data. The growth of graph-structured data in modern applications such as social networks and knowledge bases creates a crucial need for scalable platforms and parallel architectures that can process it in bulk. Despite its prominent role in big data analytics, MapReduce is not the optimal programming model for graph processing. This article explains why and then explores systems in development to tackle the graph-processing challenge.

Previously in this series, you created a searchable repository of semi-structured and unstructured data — namely, Apache web access logs, WebSphere logs, Oracle logs, and email data. In this tutorial, you will enrich the repository with structured data exported from a customer database. Specifically, you will search across structured customer information and semi-structured and unstructured logs and emails, and perform analysis using BigSheets to identify which customers who emailed Sample Outdoors Company during the 14 Jul outage were more loyal than others.

A virtual system pattern is an IBM PureApplication System deployment model that definesthe cloud workload as a topology of middleware images. The virtual system pattern modelsupports only static scaling of virtual system pattern instance nodes. This article explains howto build a virtual application pattern that can implement automatic scaling of the virtual systempattern instance nodes. This technique leverages the virtual application pattern policy, themonitoring framework, and the Virtual System Pattern Clone API.
