 If you want to customize the scenarios, you can edit the `run.sh` file which defines the previous layout of test.
 You can edit the resources requested by the pods (clients or servers), in order to have a Guaranteed QoS.
 You can change the variable `multibench_script` to keep several scenarios ready and easily switch from one to another.
 
+Note: For multibench daily jobs, workload launched is from directory "/root/crucible-examples/multibench/openshift/example-A/daily" on multibench-vm using the script "run-daily.sh" which inturn uses input json file "all-in-one.json".
