Debugging workflow:
-  Open top and do first analysis
-  Open grafana and ask yourself question while you see the graphs:
    -   Are disks free enough?
    -   When do events happen?
    -   Is there a cascading effect?
    -   Is there a wall to see??
-   Verify systems and disks in AWS
-  Log in to nodes in iterm parallel sessions and run the same commands on all of them from the same state.
    -   df -h
