aix performance monitoring commands

For system and network administrators, it is a heavy task to monitor and debug the performance of Linux systems on a daily basis. After 5 years working as an administrator in the IT field as a Linux system, I gradually realized how difficult it was to monitor and keep the system up and running. For this reason, we have written a list of the 18 most commonly used command-line tools that will help each Linux/unix system administrator work. These command

, the configuration of the snmp protocol is relatively cumbersome, but the system itself provides many performance monitoring commands, such as sar, iostat, and free, that can be periodically and periodically executed, this facilitates monitoring. These commands can be embed

Linux performance testing and monitoring SAR commands SAR (System activity Reporter report) is one of the most comprehensive system performance analysis tools available on Linux, which can be used to report the activities of the systems in many ways, including: Read and write of files, usage of system calls, disk I/O,

1. Overview Monitoring is an indispensable part in checking system problems or optimizing system performance. 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 scope of system problems or

designed to monitor Ethernet address resolution (changes in Mac and IP addresses) on Linux. He continuously monitors Ethernet activity for a period of time and outputs a log of changes in IP and MAC address pairs. It can also send an email notification to an administrator, alerting you to an increase in address pairing. This is useful for detecting ARP attacks on a network.suricata– Network Security MonitoringSuricata is an open source high-performance
