Enable sar command on CentOS (install sysstat)

1. Environment

[root@CENTOS7 ~]# cat /etc/redhat-release
CentOS Linux release 7.7.1908 (Core)
[root@CENTOS7 ~]#

2. Install yum-utils

Although it is not related to the sar command, install yum-utils to use the repoquery command to check the files included in the package. If you install sysstat without installing yum-utils, you can use the sar command.

yum install -y yum-utils

Execution result


[root@CENTOS7 ~]# yum install -y yum-utils
