If you're looking for a very easy-to-use Linux performance monitoring tool right now, I highly recommend installing and using the Nmon command-line utility.Nmon Monitoring ToolsThe Nmon is a system administrator-oriented tuning and benchmarking tool that can be used to display performance data about the following:

The operating system monitoring tool monitors the usage of operating system resources and indirectly reflects the running status of each server program. The analysis based on the running results can help us quickly locate the system... information nb 1.

Recently encountered with a jboss performance problem, in order to troubleshoot the problem convenient, decided to open JMX, using jconsole for real-time monitoring to analyze performance. The configuration steps are as follows:For details see: https://docs.jboss.org/author/display/WFLY8/JMX+subsystem+configuration1, configure the service side:A, the Analysis Wil

More and more attention has been paid to the concept of devops in recent years, and more and more software is available in addition to the traditional Splunk,zabbix external open source field. From data collection, time series database, graphic display and other major aspects have a variety of extensible software to build a data monitoring platform ( Detailed list ), Logstash+elasticsearch+kibana is written more, this article will focus on business

Linux disk performance monitoring In linux, many commands for viewing processes are also very powerful. Commonly Used Commands include: ps top However, the disk performance monitoring is not so uniform. The following lists some disk monitoring commands, which only serve as a

The commands for viewing a process are very large and powerful under Linux. Often used such as: PS TopHowever, there is less uniformity in disk performance monitoring.Some disk monitoring commands are listed below. Here is just a starting point, the specific use of reference please refer to the Man manual.One DFThe DF command gets the amount of space that the hard disk is taking up. It also shows how much s

Linux provides a very good file Virtual System (/proc) to monitor system performance. The/proc file virtual system is a mechanism used by the kernel and kernel module to send information to processes. It exists in the memory instead of the hard disk. The main functions of the/proc file virtual system include process information, system information, CPU information, load information, and system memory information. 1.

Every time a prime number is found, the multiples of all the prime numbers in the array are set to false. The next prime number is the next real bit in the array.
