+**Important:** 
+* Ensure that the `alloc_count` variable is included in the job
 specification. If it is missing or undefined, the job will fail to run, 
 potentially disrupting the upgrade scenario.
 
+* During normal execution of the test and to verify the health of the cluster,
+the number of jobs and allocs running is verified multiple times at different 
+stages of the process. Make sure your job has a health check, to ensure it will 
+be restarted in case of unexpected failures and if it is a batch job,
+it will not exit before the test has concluded.

 If you want to verify your workload without having to run all the scenario, 
 you can manually pass values to variables with flags or a `.tfvars`
 file and run the module from the `run_workloads` directory like you would any
