This article lists the network and monitoring commands that every Linux user should know about. The network and monitoring commands are similar to the hostname, ping, ifconfig, iwconfig, netstat, nslookup, traceroute, finger, telnet, and ethtool commands for viewing linux Se

There are three main kinds of tools for monitoring the back-motion of online system: System monitoring Interface (SMI), Tbstat and Tbcheck. First, the System monitoring Interface (SMI) we mainly use SQL command operation online Internal Database sysmaster internal table/structure, to obtain relevant maintenance information. The Sysmaster was created automatically

1. Display Server Status: Db.serverstatus () 2. MongoDB can monitor data through profile to optimize it. Check whether the profile function is currently turned on: Db.getprofilinglevel () returns level, value 0|1|2, meaning: 0 for off, 1 for slow command, 2 for all Open profile function: Db.setprofilinglevel (level,slowms); #level等级. At level 1 o'clock, the slow command defaults to SLOWMS (unit ms)(that is, execution time is greater than slowms for slow

The basic functions of the top command and ps command are the same, displaying the current process of the system and other conditions. However, the top command is a dynamic display process, that is, you can press the key to continuously refresh the current state. Such? The front-end executes this command, and it will exclusively occupy the front-end until the user terminates the program. More accurately, the top command provides real-time monitoring o

Pidstat appears to be in some newer versions of the 2.6 kernel, and needs to install the Sysstat package.Under Ubuntu, you can install it via the sudo apt-get install Sysstat.SAR commandCommand:Sar-x PID 1 1000 SAR can also specify the corresponding PID, focus on a fixed number of parameters, not pidstat so powerful. I can't see the corresponding I/O, IR and other information.The functions of the SAR can be covered by Mpstat, iostat and related functions.Dstat commandCommand:Dstat-y--tcp

Analyzer or packet sniffer program-to capture or filter TCP/IP packets received or transferred from a specific interface on the network. It also saves the captured package to a folder. Tcpdump can be used on all major Linux distributions.5.netstat--Network StatisticsNetstat is a command-line tool for monitoring incoming and outgoing network packet information and interface information statistics. It is useful for system administrators to use it to mo

signal the process through the PID. By default, the KILL command sends a term signal to all the PID listed on the command line, and unfortunately it can be used only with the process number and not the command name, so it is sometimes not useful.The-s parameter supports specifying other signals (with signal names or signal values). The KILL command will not have any output. Here's a chestnut:1 Kill 8080　　It is equivalent to the following chestnuts:1 Kill 1 8080Killall command　　The Killall comma

Linux performance monitoring and Common commands As a DBA, it is also necessary to have certain Linux server performance monitoring knowledge. Sometimes Oracle database performance problems are caused by server performance bottlenecks. That is to say, from the Oracle perspective, there is almost no waiting or Error Tracking in alert log, however, the system is st

CPU load, the CPU should be more service user process, in general, I would like to see the system process accounted for 20% or 30%, user processes accounted for 70% or 80%. If the%usr>80 for a long time indicates that CPU resources are basically consumed by user processes, there is a noticeable bottleneck in the CPU. If the%USR value is rarely >80, the system's possible bottlenecks exist in the middle of the CPU, memory, or I/O. If the%wio value is >15, this is a signal that the disk has a bott

Detailed explanation of iostat commands for real-time IO monitoring in CentOSIntroduction Iostat is mainly used to monitor the IO load of system devices. iostat displays the statistics from the start of the system when it is run for the first time. After iostat is run, statistics from the last run of the command are displayed. You can specify the number and time of statistics to obtain the required statisti

testing, the process of selecting a Web server can be the peak of the process or the thread has been down, pressure measurement, until CS to a relatively small value, the process and the number of threads is a more appropriate value. System calls are also, each time the system function is called, our code will enter the kernel space, resulting in context switching, this is very resource-intensive, but also try to avoid frequent calls to system functions. Too many context switches means that mos
