aix performance monitoring tools

Linux performance monitoring study notes www.2cto.com Linux performance monitoring is generally divided into these aspects: 1. CPU 2. Memory 3. IO 4. Network these four aspects are independent of each other but affect each other. Common performance

Network monitoring is the most complex in all Linux subsystems, with too many factors, such as latency, blocking, conflict, and packet loss, even worse, the routers, switches, and wireless signals connected to Linux hosts all affect the overall network and it is difficult to judge whether the problem is caused by the Linux network subsystem or other devices, monitoring and network judgment are the most comp

First, Nmon is a very good UNIX, Linux under the system performance monitoring tools. Quoted by Baidu know: The Nmon tool helps to display all of the important performance optimization information on one screen and dynamically updates it. This efficient tool can work on any dumb screen, Telnet s

ArticleDirectory Htop Iftop Dstat Original article link In Linux, CPU, memory, and other system statuses can be viewed using the TOP command, or graphical tools such as gnome-system-monitor. However, if you want to know more detailed information, such as the process tree and the specific use of the network, these tools will be powerless. In this article, we will introduce several

Deep observation of Glassbox Inspector with AspectJ and JMX Introduction: As Ron Bodkin describes how to synthesize the AspectJ and JMX groups in a flexible and modular manner, you can say goodbye to messy and tangled code. In the first part of this article, which is divided into two parts, Ron helps you build a monitoring system with the code and ideas from the Open-source project Glassbox Inspector, which provides information that identifies specif

CPU performance indicators 1. CPU usage ratio of user processes 2. CPU usage ratio of System Processes 3. WIO, waiting for I/O is the ratio of the CPU in idle state. 4. CPU idle rate 5. Percentage of CPU used for context switching 6. Nice 7. Real-time 8. Length of the running process queue 9. Average Load Tools commonly used in Linux to monitor CPU performance i

Because Nagios is too complex, the previous Zabbix has emerged as a condition of knowledge. I just want to find a tool that can collect data for analysis in real time, glances is undoubtedly the best choice.In addition, when I was looking for tools, I found a relatively good simple monitoring tool--linux dashboard. On GitHub, you can go to research.Glances installation is very simple, not only support the d

Nmon (named for the Nigel Monitor) is a computer performance system monitoring tool developed by IBM employees Nigel Griffiths for AIX and Linux systems. Nmon can display the operating system statistics on the screen or stored in a data file to help understand the use of computer resources, adjust the direction and system bottlenecks. This system benchmarking too
