The usual approach is to use a separator character in a single
instance domain.  Usually the '/' character, but if that already
is significant for the domain, then '::' is sometimes also used.

In your example you might use something like

lustre.jobstats.ost.open[instA/jobid1]
lustre.jobstats.ost.open[instA/jobid2]
lustre.jobstats.ost.open[instB/jobid1]
lustre.jobstats.ost.open[instB/jobid2]

The "cgroup.blkio.dev" metrics are an example of the '::' case.

cheers.
