1. Introduction:Javamelody can monitor Java or Java EE application servers in a running environment. It is displayed as a graph: Java memory and Java CPU usage, number of user sessions, JDBC connections, and HTTP requests, SQL requests, JSP pages and Business interface methods (EJB3, Spring, Guice), average execution time, Error percentage, and so on. Charts can be viewed by day, week, month, year, or custom time period.2. Prepare:Download Javamelody-

Monitoring indicators Metrics that typically require monitoring for performance testing include: 1. Server Linux (including CPU, Memory, Load, I/O). 2. Database: 1. Mysql 2.Oracle (Cache hit, index, single SQL performance, database [/url] threads, number of data pool connections). 3. Middleware: 1. Jboss 2. Apache (including number of threads, number of connections, log). 4. Network: throughput, throughput

CPU usage. T is sorted by time/accumulated time. W writes the current settings to the ~/.TOPRC file. This is the recommended way to write top configuration files. (7) Last skill: Top command Tips 1. Enter uppercase P, the result is sorted by CPU consumption in descending order. 2. Enter capital M, and the results are sorted in descending order of memory consumption. 3. Press the number 1 to show the load of all CPU cores. 4, top-d 5 refresh every 5 seconds, default 1 seconds 5. Top-p 4360,4358

Tsar is a collection of information on the server system and application of the collection reporting tools, such as the collection of server System information (CPU,MEM, etc.), as well as application data (Nginx, Swift, etc.), the collected data stored on the server disk, can always query historical information, Data can also be sent to the Nagios alarm. Tsar can

Key Infrastructure Monitoring (core Infrastructure monitoring , CIM )In today's cloud infrastructure, hardware failures are unavoidable. Core Infrastructure monitoring detects early signs associated with hardware bottlenecks and captures hardware failure signals to respond to larger problems before they occur. The scope of infrastructure

One of the primary goals of managing certificates is to improve the security level of the enterprise, where authentication and access management should be valued.
