I'm not sure how that would help us.  A container running out of resources
doesn't crash - parsoid runs almost using all the allocated memory and
parsoid+trac+others hit their cpu quotas sometimes and just keep running.

Maybe it would be more useful to monitor client metrics, like can we reach
the service over http?

That is a feature built into docker.  I've enabled it in container.yml (as
a global default) and restarted trac with the new parameters.

Thanks,
