microservice performance monitoring

Linux performance monitoring and analysis tool background recently, a pre-developed system performance test is required. The system is deployed on the Linux server cluster. In high concurrency and high load scenarios, you can collect all the information (including CPU, memory, I/O, disk, and network traffic) occupied by each device... linux

Tool: linux performance monitoring tool-nmon, linux-nmon Nmon download: http://pan.baidu.com/s/1jICoSpo It can be run directly in linux. The nmon tool can display all important performance optimization information on a single screen and dynamically update it. The nmon tool allows AIX and Linux performance experts

Nmon (named Nigel's 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 direction and system bottlenecks. This system benchmark tool only needs to use one command to get a lot of important

KDESystemGuard (KSysguard) is a KDE tool for task management and performance monitoring. It adopts the client/server architecture and can monitor the local host or remote host. The following is the usage method: Default KDE System Guard window The front-end graphic interface uses sensors to obtain the information to be displayed. The sensor returns a simple value or more complex information, such as a table
