Thankyou Stuart,
Just to confirm, if what you say is happening all older stats other than
what is being displayed have been lost.

I am attempting to reconfigure our statistics. However when I
run the required scripts I am not getting any stats older than 2 months
ago.
When I look in the .dat files in /dspace/log that have been
generated they are almost except for the last 2 months empty even though
a lot has occured for the last 3 years.
I am pretty sure I have all the log files.
I have only changed the date in the dstat.cfg file.
An example of an empty dat file is below.
Any advice for me
I suspect what is happening is that your dspace.log.* files have rolled
over their limit. In [dspace]/config/log4j.properties you can specify
how many log files to keep, and how big each one can be before it rolls
over. The default configuration is quite small (100 files at 1Mb each).
So it sounds like you are getting through that many log files each 2
months.
The problem with the stats module as it stands, is that despite creating
.dat files for log files which have now rolled over and been lost, it
recreates them all each time. This means you lose all the older stats.
The easy short-term solution is to increase the size and/or number of
log files that DSpace creates.
The better solution would be for someone to look at making sure current
.dat files are not overwritten by the stats system. However... the stat
system is getting a complete rewrite in the upcoming 1.6 release, so a
lot of people are waiting for that instead.
I hope this helps,
