Can we get the performance of the system under test

Hi Team,

When we run the below command, hope it will fetch the metrics of the open search dashboard cluster… But can we get the performance metrics of the system under test where OpenSearchDashboard is not installed… If Yes, could you please share the steps to do it…

./opensearch-perf-top-linux --dashboard ClusterOverview --endpoint localhost:9600

Thanks,
hema
