Re: [Xen-API] XCP 1.6: last_shutdown time/shutdown reason/initiator

[George Shuklin <george.shuklin@xxxxxxxxx>]

Yes, if possible. Those fields was very useful.

Some use cases:

1) They can be used to detect crashed VM's. If SR is going offline and 
VM mount options says errors=panic, VM is crashing. Those fields allows 
very easy to search for crashed VM and restart them after SR is repaired.
2) Status 'crashed' allows to answer customers about reason why their VM 
was rebooted.
3) If 'last_shutdown_reason=rebooted' and VM is not started, that is 
sign of problems (bad boot kernel, grub options or something else).
4) last_shutdown_time allows native and very intuitive sorting key for 
halted VM's (if vm was halted recently, it can be on top, and vm with 
shutdown date two years ago naturally can be at the list bottom).
5) When some complicated works with infrastructure are planned, 
last_shutdown_time allows to predict if VM will be started soon or not 
(if it was halted recently, it can be started at any time, if vm was 
halted two weeks ago, there is very little chance it will started in 
near 1-2-3 hrs.)

We displays them to client in management interface
