[goshanecr]

Good day!

I have a periodical freeze with one of FreeBSD instance. Logs have not any messages, and I want start collecting system info every 5 seconds for example and write it to log files, for diagnosting after freeze.
That PC has a VirtualBox instance, ZFS on GELI based providers and samba service.

Tell me please, what kind of info I need collect? Now I collect such info:
iostat -x -z
vmstat -i
vmstat -s

And give me please link to resource where I can undestand how to interprete that information.

Thanks!
