Editor to share with you the use of linux tsar command to collect server system information, I hope you will learn a lot after reading this article, let's discuss it together!

Tsar is a collection tool developed by Taobao (similar to sar tool), which is mainly used to collect server system information (such as cpu,io,mem,tcp, etc.) and application data (such as squid haproxy nginx, etc.).

The collected data is stored on disk, and the historical information can be queried at any time. The output mode is flexible and diverse. In addition, the data can be stored in mysql or sent to the nagios alarm server.

When displaying data, tsar can specify a module, and merge can output data with multiple pieces of information, and real-time information in seconds can be output with-live parameter.

Tsar is a program based on modular design, which consists of two parts: framework and module.

The source code of the framework program is mainly in the src directory, while the module source code is mainly in the modules directory.

The framework provides the parsing of the configuration file, the loading of the module, the parsing of the command line parameters, and the analysis and output of the interface of the application module to the original data of the module. The module provides an interface to the framework call.

Tsar relies on cron to collect data every minute, so it requires the system to install and enable crond. After installation, tsar executes tsar-cron every minute to regularly collect information and record it to the original log file.
