I wonder if we can automate running it on OST failures to get automated
failure analysis.
Well, ovirt-log-analyzer doesn't provide failure analysis, it just tries
to extract more important lines from the logs and add some information
to them. It may or may not be useful to add its output to OST failures
in future, but some feedback and testing are needed first, I assume
there are still bugs and things to improve.
