Real-time monitoring commands, watch is a very useful command, can help you to monitor the results of a command in real time, save the manual run over and over again. The two most common options for this command are-D and-N, where-n indicates how many seconds interval is executed "command", and-D indicates where the highlight has changed.Examples of usage:1) Execute the WHO command once every second to monitor the status of the server's current user l

MongoDB comes with a web interface monitor.Configuration is simple, only need to add parameters at boot time:--httpinterface or write httpinterface=true to the configuration file to restart. Enter in the browser: Ip:mongodb port number +1000 For example, the database port is 20011, the monitoring page is: ip:21011/export/mongodb/bin/mongod-f/export/mongodb/conf/mongod.conf--httpinterfaceYou can also add a--rest parameter. can see more parameters/expor

1. Display Server Status: Db.serverstatus () 2. MongoDB can monitor data through profile to optimize it. Check whether the profile function is currently turned on: Db.getprofilinglevel () returns level, value 0|1|2, meaning: 0 for off, 1 for slow command, 2 for all Open profile function: Db.setprofilinglevel (level,slowms); #level等级. At level 1 o'clock, the slow command defaults to SLOWMS (unit ms)(that is, execution time is greater than slowms for slow commands). View the curr

Linux performance testing and monitoring sar commands Sar (System Activity Reporter System Activity Report) is one of the most comprehensive System performance analysis tools on Linux. It can report System activities from multiple parties, including: file read/write, system call usage, disk I/O, CPU efficiency, memory usage, process activity, and IPC-related acti

request processing to different controllers. Similarly, Struts Actionservlet is delegated to the Action subclass that acts as a controller. In the second part of the article exploring performance monitoring with AspectJ, I extended the Glassbox Inspector to provide more meaningful information about application performance by adding monitors. These monitors trac

Php performance monitoring module XHProf 1. What is XHProf? XHProf is a hierarchical PHP performance analysis tool. It reports the number of requests and various metrics at the function level, including the blocking time, CPU time, and memory usage. The overhead of a function can be subdivided into the overhead of callers and callers. In the XHProf data collectio

Performance statistics, such as memory CPU process information, have long been written, but have not tried to graphically visualize their data through the interface.One is that you are unfamiliar with the interface and have been learning about other aspects.Just recently saw a good code on the CodeProject website and decided to try to use his code to try to visualize system performance data.Graph Code for C
