The SBK (Storage Benchmark Kit) - GEM (Group Execution Monitor) combines SBK-RAM and SBK. you can just execute the SBK instances on multiple hosts with single SBK-GEM command. For any given cluster, you are running ssh-server in each node of the cluster , then SBK-GEM can be used run the SBK in all the nodes of the cluster. The SBK-GEM copies the SBK application to all nodes of the cluster. The node in which SBK-GEM command issued executes the SBK-RAM and in all the given nodes SBK command is executed. The SBK-RAM integrate the performance results supplied by remote nodes.
SBK-GEM is a submodule/project of the SBK framework. If you build SBK, it builds the SBK-GEM package too.
The standard help output with SBK-GEM parameters as follows

Note that at the results, The SBK-GEM prints the return code of each of the remote host.
The SBK-GEM executes the SBK-RAM in local host; and SBK-RAM by default it starts the http server and all the output benchmark data is directed to the default port number: 9719 and metrics context. you can refer SBK-RAM grafana Dashboards for further details.
