Hello StarlingXers,
We have been thinking in how to measure StarlingX performance, in order to do so, we would like to present you an initial proposal in order to get feedback and ideas from you guys.
The proposed metrics for StarlingX performance are:
* Detection of failed VM – tracked on milliseconds
Are we talking the qemu process or intrusive guest monitoring? (Or both?)
* Detection of failed compute node – tracked in milliseconds
Different failure modes (power outage, mgmt link failure, critical process failure) could result in different detection times.
* Auto controller node failure recovery - No impact on StarlingX * Network link failure detection – tracked in milliseconds with no major impact on StarlingX
What about network failure beyond the first hop (so we don't lose carrier)? How about time from dead-office-recovery to instance network connectivity? Do we want to consider OpenStack performance? Chris
