Not able to collect the data for CPU attribute using SSH mode on RHEL 8 with OpManager

Hi All,

I try to monitor a server on RHEL 8 with OpManager but the CPU not show metrics:

The error is "Not able to collect the data for CPU attribute using SSH mode"

I installed the package:

yum install redhat-lsb-core

And sar command:

root$sar
bash: sar: command not found...
Install package 'sysstat' to provide command 'sar'? [N/y] y

The following packages have to be installed:

 sysstat-11.7.3-7.el8.x86_64    Collection of performance monitoring tools for Linux
Proceed with changes? [N/y] y

Please check if data collecting is enabled


any idea to solve that?
