In this section, we will enumerate and explain the specific use of metrics.2.1 Coupling1974, Steven et. In the context of structured progr

Previously introduced in the Healthcheck how to add some simple health detection through metrics LIB to the system, now talk about Dropwizard metrics more important parts, record the system's measurement information. Dropwizard offers a variety of metrics: The simplest counter, the complexity of the histogram for calculating the time distribution, the meter for c

ecosystem. This article describes how to use ganglia to collect various hbase metrics and focus on solving the following two issues: (1) how to filter hbase indicators that are too many? (2) After modifying the hadoop-metrics.properties, do not need to restart hadoop or hbase. 1. hbase metrics Configuration Taking hbase-0.98 as an example, you need to configure hadoop-metrics2-hbase.properties # syntax:

Google Analytics Deploy custom dimensions and metricsAugust 12, 2013 Abbo 7 Comments To use Google Analytics's custom dimensions and metrics, we first have to recognize the concept of dimensions and metrics. In simple terms: dimensions are the angle of our perception of things, and indicators are the way we measure things. From the database point of view, dimensions and indicators are fields,

Pokemon per second processing of Go cloud data storage (expected vs Actual) This can happen, and you should be prepared for it as well. This is also the article in this series to mention. In this series of tutorials we'll show you what you need to track, why you're tracking them, and what you need to do to deal with possible root causes. We'll show you each indicator, how to track it, and what you can do to take action. We will use different tools to collect and analyze this data.

Article Description: Google's application of this user-centric indicator system provides a very good reference for quantifying the user experience by providing a broadly adaptable dimension framework, as well as a process of creating specific metrics. Thank @liuyaping for sharing and exchanging the metrics of the user Center in Ali's work, which is very enlightening. Google's application of this

Ttoms the baseline'll be lower, so-make a correct match you should know where is the baselines of each word exactly Located. So we need to know the Ascent value of the text. If the got the ascent value, we can easily align the words on the baseline as seen on following image. For a complete information on typography see this article on Wikipedia.For a proper drawing of words in different sizes, should align them on their baselines.As seen on the above image, have the information of the ascent v

Starting with VS2008, there is a new tool to help developers better understand the code they write. This tool is "calculated code metrics." For a specific description of this feature and several indicators, please refer to the official documentation below Code metrics are a set of software metrics that enable developers to better understand the code they are

systems.In Java there is an open source project called Metrics, which captures the JVM and application-level performance parameters, and his author, Coda Hale, describes what Mertics is and why metrics is necessary in an application system, Videos and speeches can be downloaded separately on YouTube and SlideShare. The project that has been ported in. NET is called Metrics.net.Before you start introducing

Introduction: Software metrics can help you look for hidden design elements in your code so they can become idiomatic patterns. This phase of evolutionary architecture and emergency design explains how to use metrics and visualization to discover important code elements that are masked by complexity. One of the challenges of emergent design is finding idiomatic patterns and other design elements that are h
