[one-users] measuring the diration of a migration

[Adnan Pasic]

Unfortunately I’m a newbie in Linux, so „a little grep magic” is already too
much for me L

Up until now I managed to list all state-transitions ( cat vm.log | grep
“New VM state is” ), but how could I now get the times out of those lines,
and more importantly, how can I subtract the time of RUNNING with the time
of MIGRATE?

 

Any help would be appreciated, since I’m kind of stuck here L

Thanks!

Hi,

That times can be extracted from oned.log or <vm-id>/vm.log with a bit of
grep magic, just look for the state transitions and take a look at the VM
life-cycle documentation [1].

Or you could modify the vmm scripts and log the operations to your own file.

Regards.
