Previous article The beauty of the front-end data I believe that we have a certain understand

Note: The original is:Andyguo: "Web performance Monitoring and Analysis "Performance testing requires the use of different tools, combined with system logs, monitoring servers, applications, and many other indicators. The following is a description of monitoring indicators,

for Java performance More concerned about the students probably know the "Java performance" this book, in general, many students in the daily writing Java Code is seldom to care about performance issues, but in the process of writing Code we must take into account the impact of performance on the program. As small as w

Nmon is a monitoring and analysis tool widely used on AIX and various Linux operating systems, and the information recorded by Nmon is more comprehensive, it can capture the usage of system resources in real time while the system is running, and can output the results to the file. The Nmon tool helps to display all of the important performance optimization information on one screen and dynamically updates i

Performance testing requires the use of different tools, combined with system logs, monitoring servers, applications, and many other indicators. The following is a description of monitoring indicators, monitoring tools, bottleneck analysis.Service-Side Monitoring metricsThe

372 47 90 10 0 0From the first result above, we can see that the last column (ID) represents the idle time. We can see that during baseline statistics, the CPU idle time is between 79% and 100%. the second result shows that the system is in the 100% usage and there is no idle time. from this comparison, we can determine whether the CPU usage should be optimized.2.0 install monitoring toolsMost * nix systems have a bunch of standard

Server monitoring?? In addition to deploying WebApp, you need to monitor the service's exception information and server performance metrics when building the server, and notify the administrator of any exceptions.?? The server was built using Linux+nginx-1.9.15+tomcat7+java.?? Write scripts to detect error logs and server performance metrics, and use cloud

Looked at such a tutorial, read a manual, according to the requirements to change a set, system settings, kernel parameters that the idea of a system optimization is silly very naïve: the system optimization is a complex, cumbersome, long-term work, optimization needs to be monitored, collected, tested, evaluated, optimized after testing, collection, evaluation, monitoring, And is a long-term and continuous process, not to say now optimization, testin
