each user to the system. In the background there are two daemons running, one is keeping an eye on the overall activity of each user on the system, and the other process is concerned about what resources are consumed by them.This tool is useful for system administrators to track each user's activity, to know what the user is doing, what commands are being issued, how much resources are being consumed, and how long it takes to be active on the system.

we will introduce).TopThe top command displays the current active process, which, by default, is sorted by the severity of the CPU consumed, refreshes the list every 5 seconds, and you can choose a different sort method, for example, M is a shortcut key to sort by memory footprint.UptimeThe uptime command tells you how long this server has been running since booting up to the present time. It also contains the average load from boot to current server.VmstatYou can use Vmstat to monitor virtual

PS and pstree commands are the best friends of Linux system administrators and can be used to list all running processes. PS tells you the memory and CPU processing time occupied by each process, while pstree shows less detailed information, but it displays the dependencies between processes in a tree structure, including sub-process information. Once a process is found to be faulty, you can use kill to k

Guide Below is a list of the 10 basic network and Monitoring commands that each Linux user should know about.Network and Monitoring commands are similar to these:hostname, Ping,ifconfig, Iwconfig, netstat, nslookup, tracerout

save Nmon execution results to a CSV file To facilitate future analysis. In the daily monitoring work, I found that Nmon is my most used tool. PmapThe PMAP command is used to report the details of how each process consumes memory and can be used to see if there is a process overrun, which requires a process ID as a parameter. PS and PstreeThe PS and Pstree commands are the best friends of

network protocol statistics NmonNmon, the abbreviation for Nigel's monitor, is a popular open source tool for monitoring the performance of Linux systems. Nmon monitors performance data for multiple subsystems, such as processor usage, memory utilization, queues, disk I/O statistics, network I/O statistics,

I listed below the 10 basic Linux users should be aware of the network and monitoring commands. Network and Monitoring commands are similar to these: hostname, ping, ifconfig, Iwconfig,

to monitor as long as you enter a single command. For example, to get statistics on the processor, memory, and disk, just enter C, M, and D separately. You can also use Nmon with the-f flag to save performance statistics to a CSV file for later analysis. As far as day-to-day server monitoring is concerned, I think Nmon is one of the most useful programs in my Linux System Management Toolkit. 　　Pmap Th

In Web site performance optimization, we often have to check the various indicators of the server in order to quickly find the black sheep. In most cases, we use monitoring software such as cacti, Nagois, or Zabbix, but this kind of software is cumbersome to install, and in a small server we want to find out as quickly as possible, or use some of the commands that Linux
