Dear All,
We are using ELOG from http://midas.psi.ch/elog/index.html and would
like to be able to have an IOC make automated e-log entries. This
particular package comes with source code for a command line tool for
making entries and I assume this can be easily adapted to the task at hand.
I am wondering if others have done similar things and if they have any
advice.
It seems non-trivial to manipulate lengthy strings in an IOC (use
waveform record?) so I was thinking it might be easier to create device
support that reads in a file of pre-canned messages on start-up and then
have an output record pass to device support an index to one of these
messages.
However I can also think of other ways to do this, e.g. an external
script that monitors a particular record via Channel Access and does the
appropriate things when it sees a change.

Just for your information.

We use our home grown electric lognote sytem, which we call zLog,
togather with a python script correcting events from EPICS system and

putting messages into backent RDB, postgreSQL.

This srcipt is running as a background process on our server unix
machine. It monitors channels in the configuration file and put a record
inluding pre-defiend message into the database running on other unix
server over the network. Once the record is put into the database,

user can view and edit the record from a web browser.
It is a rather simple program but quite useful for us.
Btw, this script is written by a member of the KEKB operators group.

I am open to ideas. Thanks,

p.s. What type of person write to Tech-talk at 10:00 PM ???
