[Orca-users] Re: collecting data across multiple hosts

[D.C.Lawie]

Hi,

your second idea is the correct one.  Blair suggests nfs mounting the relevant
directory to the orca host.  I use rsync ( http://rsync.samba.org ), which we
use for a fair bit of file-pushing, running from the cron.  ftp working from
the cron would do the same job.

However you transfer the files,  orca will happily pile them all into one web
tree as long as the data files are collected into the directory tree suitably.

e.g.

/var/orca/orcallator/host1/percol....
/var/orca/orcallator/host2/percol....

HTH,
Duncan.
