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
- htop
- du -h /data
- ls -alh /var/log
- tail -f /var/log/syslog
- dmesg
