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,

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

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

If the got the ascent value, we can easily align the words on the baseline as seen on following image.

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

This is a creation in Article, where the information may have evolved or changed. Since go 1.5, every go release, Gopher Brian Hatfield has been basking on Twitter for the performance data of the new Go runtime (compared to previous go versions). Even when the Go team staff do speaking around the world, Brian's pictures are also quoted in slide. Later, Brian Hatfield packaged its code for measuring Runtime performance data into a library and put it on GitHub, and we could use the library to buil

1. Overview of completeness metrics The runtime's system integrity is guaranteed by the system's access control mechanisms, such as DAC (Discrete access control, indirect access controls)/mac (Mandatory access control, mandatory access controls, such as SELinux, Smack). DAC/MAC cannot detect offline modification of files, Encrypting File System can protect illegal access, but it is expensive and relatively inefficient. Integrity measu

Before we introduce the disk I/O monitoring commands, we need to understand the metrics for disk I/O performance monitoring, and the performance of some aspects of the disk revealed by each indicator. Indicators for disk I/O performance monitoring mainly include:Indicator 1: Number of I/Os per second (IOPS or TPS)For disks, the continuous read or continuous write of a disk is called a disk I/O, and the IOPS of the disk is the sum of the number of cons
