Tim and John,

I looked into the channel archiver as well and came to the conclusion
that the SDDS toolset developed here at the APS by Mike Borland and
company is a far supperior solution.

For those of you unfamiliar, the SDDS toolkit is a set of 70 or so tools
which can be combined to perform various types of actions on data.
There are also a handful of extensions which provide EPICS support (in
particular sddsmonitor or sddslogger).

Sddslogger, for instance, can be set up to log PVs at a particular data
rate for a specified time, etc...  The data is saved into a file which
can be plotted with another SDDS tool sddsplot.  Or it can be converted
to a spreadsheet file with sddsprint.  Or various statistical analysis
calculations can be performed on the file and then exported to another
file for viewing/printing, etc...I think you get the point.

What's more, it's possible to do certain types of automated tasks such
as scanning one PV verses another and recording the results.

While I haven't done much more than implement a few simple logging
tasks, I have seen enough of what this system can do to sell me on its
merrits over the channel archiver and I am actively (well, in my spare
time anyway) working towards using this system for something more
substantial such as aligning of our microprobe prior to starting an
experiment.

Documentation on this toolkit can be found from the APS documentation
pages--specifically http://www.aps.anl.gov/asd/oag/oagPackages.shtml.
