Tomcat is a small, lightweight application Server and one of the most commonly used servers for Java EE developers. However, many developers do not know that the Tomcat Connector (Tomcat connector ) has bio,nio,Apr Three modes of operation, So what's the difference between these three modes of operation, and how do we change the running mode of

Because more than one Tomcat is installed on a Web application server, there are multiple ports, such as the default of 8080, followed by additional 9100,9300,9500, and so on. A cacti_host_template_tomcat_server.xml template can only be specified to monitor a tomcat service port.So if you want to monitor more than one Tomcat server on a Web server, then you have

(Turn around, source address: http://www.jmatrix.org/notes/1067.html)Recently, I wondered if it was possible to continuously collect the performance information of the Tomcat server itself by adding a tomcat extension, such as the data of the thread pool, the number of requests, and so on, so as to be able to coordinate with the

In practical use, we often monitor tomcat performance. You need to configure the appropriate parameters to provide remote connections to monitor the performance of the Tomcat server. This article describes in detail how to configure the Tomcat parameters in step-by-step. All

Label:The IO performance of SQL Server is affected by the IO latency of the physical disk and the IO operations performed internally by SQL Server. When monitoring disk performance, the primary measure (metric) is IO latency, which is the time delay in creating an IO request from application to disk to complete the IO request. SQL Server is prone to

Oracle recommends that you replace Statspack with this. 1. AWR is essentially an Or

In parts 1th and 2nd of this series (a total of three articles), I introduced the techniques and patterns for monitoring Java applications, in which I focused on the JVM and application classes. In this final installment, I'll introduce tips for collecting performance and availability data from application dependencies, such as the underlying operating system, the network, or the application's back-end data

Then we manage the server when the WINDOSW system is more intuitive, how much CPU use, how much bandwidth memory used, etc. as long as in the Remote Desktop Task Manager at a glance. But in the Linux environment is not so easy, especially the server or VPS running is a large web site, if you can not find the server performance consumption in time, it is likely to lead to the site in the peak visit, there is no known card death. So, eagle, then. This a

In our web project, our common Web application servers are tomcat, Weblogic, and WebSphere. They are infrastructure software for Internet applications, also called "middleware," which handles dynamic on-page requests, provides names, transactions, security, messaging, data access, and so on, and provides the development, deployment, operation, and management capabilities that should be built.How do we better monitor and diagnose
