First, let's take a look at the more than 10 monitoring Commands We're talking about:
1.dstat--Multi-type resource statistic tool
the command consolidates the Vmstat,iostat and Ifstat three kinds of commands. It also adds new features and features that allow you to see all of your resource usage in a timely manner, allowing you to compare and integrate different resource usage scenarios. The interface with different color and block layouts helps you to get information more clearly and easily. It also supports exporting information data to a CVS format file, which can be opened with other applications or imported into a database. You can use this command to monitor CPU, memory, and network status over time
pigoss BSM: as a commercial operation and maintenance monitoring tool. The basic performance indicators of various operating systems (Windows, Linux, Solaris, HP-UX, AIX, K1, Wave Tissot) can be monitored. such as CPU performance-related parameters, System logic and physical disk performance-related management parameters, system memory performance-related management parameters. Monitoring of basic application services . Indicators that can be monitored are: http/https,smtp/pop3,ftp,dns service, DHCP service, LDAP.
pigoss BSM Monitoring System for network equipment status monitoring mainly through the SNMP mode, can monitor the domestic and foreign mainstream manufacturers of network equipment, can monitor the relevant parameters are: CPU utilization, memory utilization, port management and operation status and inflow outflow, Inflow and outflow usage, number of unicast receive and send packets, network traffic (average traffic and maximum minimum value, etc.) and bandwidth, network link connectivity, etc. It is also possible to passively receive alerts sent by network devices via syslog, trap protocol, such as security devices, which will proactively send the information they are attacked to the management platform via traps. The performance of the line can also be detected through the ICMP protocol.
2. atop– A better ASCII code experience than top
this use ASCII the command-line tool for code display is a performance monitoring tool that displays all process activity. It can present a daily system log for long-term process activity analysis and highlight overloaded system usage resources. It contains metrics for CPU, memory, swap space, disk, and network layer. All of these features simply run atop at the terminal.
1. # Atop
Of course you can also use the swap interface to display and sort the data.
3.
slabtop– Display kernel slab cache information
This app can show how the cache allocator manages different types of objects cached in the Linux kernel. This command is similar to the top command, except that it focuses on real-time display of kernel slab cache information. It is able to display a list of display caches sorted by different sorting criteria. It can also display a header for the statistics of a slab layer of information. Examples are as follows:
1. # slabtop–sort=a
2. # slabtop-s B
3. # slabtop-s C
4. # slabtop-s L
5. # slabtop-s v
6. # slabtop-s N
7. # slabtop-s o
4.
SAR – Performance monitoring and bottleneck check
the SAR order can output the cumulative activity counter content information selected on the operating system to standard output. Its audit system based on the count value and time interval parameter outputs the specified number of monitoring information at the specified time interval. If the time interval parameter is set to 0, then the SAR command will show the average statistics of the system from boot to time. The following commands are useful:
1. # sar-u 2 3
2. # sar-u-F/VAR/LOG/SA/SA05
3. # sar-p all 1 1
4. # sar-r 1 3
5. # sar-w 1 3

saidar– simple statistical monitoring tools
Saidar is a Simple and Light weight System Information monitoring tool. Although it does not provide most performance reports, it is able to display the most useful system health data in a straightforward way. You can easily see statistics on elapsed time, average load, CPU, memory, disk and network interface.
1. Usage:saidar [-D delay] [-c] [-v] [-h]
2.–d Setting update time (seconds)
3.–c Color Display
4.–v Display version number
5.–h Show this help
pigoss bsm :pigoss BSM Operational Monitoring system for most resources can view the form of the current state of the main indicators, such as host equipment, virtualization platform, WebLogic Middleware, database, etc. As shown in.
Pigoss BSM System with more than 20 sets of statistical reports default templates, administrators can specify the time period for the statistical report and choose which resources to add to the statistics report.
