Hi Mark,

The suggested way currently to do this is to have a different
orcallator.cfg file for each group, and have the only difference
between them be the line:

find_files  @VAR_DIR@/orcallator/(.*)/(?:(?:orcallator)|(?:percol))-
\d{4}-\d{2}-\d{2}(?:-\d{3,})?(?:\.(?:Z|gz|bz2))?

Change the first

/(.*)/

to match the hostnames for the systems in each group.

Unfortunately, there's no easier way to do this currently.

You may want to create a template orcallator.cfg file that has
a find_files like this:

find_files  @VAR_DIR@/orcallator/GROUP_MATCH/(?:(?:orcallator)|(?:percol))-
\d{4}-\d{2}-\d{2}(?:-\d{3,})?(?:\.(?:Z|gz|bz2))?

and use sed or perl to create an orcallator.cfg for each group and
replace GROUP_MATCH with the appropriate regex for that group.

This also means running separate instances of Orca for each
group.

Best,
Blair
