In https://docs.redhat.com/en/documentation/red_hat_enterprise_linux/10/html/monitoring_and_managing_system_status_and_performance/logging-performance-data-with-pmlogger#setting-up-a-client-system-for-metrics-collection there are two firewall-cmd commands which otherwise correct but the first one has trailing "success" which should be removed.

Also, the guide uses yum but dnf should be preferred nowadays.

Thanks.
