sysstat is Collection of performance monitoring tools for Linux

Introduction

In this tutorial we learn how to install sysstat on CentOS 8.

What is sysstat

The sysstat package contains the sar, sadf, mpstat, iostat, tapestat, pidstat, cifsiostat and sa tools for Linux. The sar command collects and reports system activity information. The information collected by sar can be saved in a file in a binary format for future inspection. The statistics reported by sar concern I/O transfer rates, paging activity, process-related activities, interrupts, network activity, memory and swap space utilization, CPU utilization, kernel activities and TTY statistics, among others. Both UP and SMP machines are fully supported. The sadf command may be used to display data collected by sar in various formats (CSV, XML, etc.). The iostat command reports CPU utilization and I/O statistics for disks. The tapestat command reports statistics for tapes connected to the system. The mpstat command reports global and per-processor statistics. The pidstat command reports statistics for Linux tasks (processes). The cifsiostat command reports I/O statistics for CIFS file systems.
