Re: [EP-tech] archive statistics

Sorry, that was not off list as I intended.  Nothing confidential but only really interesting if you like file listings or development sagas.

Hi Yuri (off list),

Here is the listing for the ingredient.  As you can see belowalthough
there are a few files you should be able to map these into you local
archive or your current lib or site_lib directories of EPrints (i.e. one
path or another not some in lib, some in site_lib and some in your
archive).  I think we want to avoid making it a Bazaar plugin, as then
it becomes something that requires ongoing maintenance and potential
releases of new versions, which is a bit excessive for something just
quickly whip up as a useful analysis tool really only intended for an
the original developer's use.

wow, great work!

I'm still on 3.3 and I just need this info for a migration, to get some
data to put in a report.

Hi Yuri,

I was just saying to my colleague Justin, I wonder if you were a plant
(to ask this question).  He has just been working on a tool for this
very purpose, so that we can analyse repositories that are running out
of disk space to see if they genuinely need more space or if things
could be tidied up to free up sufficient space.  The tool is a bit rough
around the edges but he is happy to make it available as a 3.4
ingredient in an EPrints GitHub repository, when he has had a chance to
tidy it up (over the next few days).   If you are still on 3.3 it may be
possible to map the various files into directories in your archive and
enable as a plugin but that is not something either Justin or I have
tried to do.

The tool uses a cronjob to produce monthly disk reports rather than a
live status.  If there is a wider interest in the tool we could look to
making the tool customisable to allow a greater reporting frequency.
Unfortunately, it is not just a case of running the cron job more
frequently, although the adaptation required to the tool as a whole
should be fairly minor.

I have deployed this rough version on tryme.demo.eprints-hosting.org if
you want to take a look.  The disk reports are only available under the
Admin menu, so you would need to give me the username you used for the
account you create on tryme, so I can up this account to a repository
admin one.

Regards

David Newman

Hi!

      what is the best way to get archive statistics, like how many records
in the archive, or to have some size hint on them (for example to find
how many objects uses at least 10MB of space, 20MB and so on), how much
total space the archive use (for example only record on archive status),
maybe grouping them by type (for example thesys uses 10GB, articles uses
40GB and so on)?

I've done rough statistics using du and some unix tools but I would like
to refine them better.
