Disk I/O performance metrics and tuning method bitsCN.com Before introducing the disk I/O monitoring command, we need to understand the disk I/O performance monitoring metrics, as well as the disk performance of each indicator. Disk I/O performance metrics include:Metric 1: I/O per second (IOPS or tps)For a disk, the continuous read or write operation of a disk i

Java Metric Usage Introduction 1Metrics is a package for Java to provide measurement tools, embedded in Java code Metrics code, you can easily monitor the various indicators of business code, the same time, metrics can be very good with ganlia, graphite combination, Easy to provide graphical interface.Below is a brief introduction of how metrics is used.Maven Add

Http://blog.csdn.net/saidora/archive/2007/06/23/1663108.aspx There are three mbeans in WebLogic, and their functions are as follows:1. domainruntime mbean ServerDomainruntimeservermbean provides mbean access for domain-specific services (Application Deployment, JMS server, and JDBC data source.Com.

Management. mbeanservers. domainruntime. domainruntimeservicembean2. runtime mbean ServerRuntimeservermbean provides access to mbean activity config

JMX is a good choice for the ability to add monitoring to your project, mostly simple and versatileFirst, create an interface named Specification: Java class name + "MBean" suffixThe Java class is then generated to implement the above interface, the Mbean classThen, create the Mbeanserver, the JMX agent, to receive the client callThen, instantiate the Mbean, generate objectname, register the Mbean in Mbeans

software structure measure methodEarly software metrics were associated with functional decomposition-oriented design methods, mostly based on module metrics.Process-oriented programming, the main factors affecting the quality of software: coupling, cohesion, complexity, modularity and size.Using the software module structure diagram for analysis, can be measured from the following aspects:? Maximum number of data transfers between modules? Average o

the larger the CTR, the greater the pressure on the server. CTR is just a performance reference, and it's important to analyze the impact of clicks. Note that the Click here does not refer to a single click of the mouse, because in a single click, the client may make multiple HTTP requests to the server.8. Resource utilizationRefers to the use of different system resources, such as server CPU utilization, disk utilization, and so on. Resource utilization is the main basis for analyzing system p

a backgroundin a performance test or Linux Server operations, will involve the use of system resources monitoring, in addition to common system commands (such as top,iostat,free, etc.), a more comprehensive resource data monitoring tool is NMON, by running NMON on the server, You can periodically monitor the hardware resources and generate the collected data into a . NMON file. So, the question is, how do you parse the. Nmon file and get the performance data you care about in automated monitorin

a preface In the performance test framework development, you need to process the completed test report of the scene, summarize the performance metrics data that you are following in the report, and then write the report and send the relevant person a message. So, one of the steps is how to capture the data from the test report (e.g.,TPS, Response time, number of concurrent users, etc.). Two problem analysiswhen LR generates a test report, it saves the
