Where is this feature documented?

You guys know that there is the possibility to execute an arbitrary script on each submission of a new messge? Just use "Execute new = <script>". In the script you have access to all parameters of the message. That's maybe simple than to watch the file set.

In the documentation of course :-)

I'm probably too tired or I don't know, but of course I looked at the user's guide and the admin's guide but did not found anything about this ;-) Is there another documention which I missed somehow?

You look here: http://midas.psi.ch/elog/config.html and scroll down to "Execute New". I wonder how you ever could run elog without looking at that page.

OK thanks I'll check that out. I did not configure ELOG by myself, I only use it and wrote the Slack plugin ;-)

Aha, that's interesting too! I'll have to look more carefully through the documentation... :)

I just noticed that there are multiple messages per file, so I have to adapt the parser. I'll update this thread when I'm done!

Yeah, I suppose something like that would be both faster and more efficient than polling ELOG itself. Fortunately the ELOG disk format looks easily parsed.
Thanks for the pointer!

I recommend monitoring directly on the server. Here is an example of a very simply Python script (https://github.com/tamasgal/elog-slack) which monitors the files very efficiently and immediately pushes notifications to Slack (slack.com). Just look at the code, it's pretty straight forward and very easy to adapt it to other (web) services.
Btw. here is an ELOG entry of it https://midas.psi.ch/elogs/Forum/68224

Hi again!
I've another need that you probably already thought of :)
I'd like to be able to efficiently monitor a logbook for changes (new or edited posts) somehow. The most reasonable way I've found so far is to periodically poll a search that looks for posts after the time of the last poll. But that might note be very efficient, especially if the polling period gets short (or number of clients grows).
Is there some other feature that could be used for this? I was thinking maybe the ETag or Last-Modified HTTP header field could be used to show changes to a logbook by just reading the headers, but it would also require HEAD request support which does not seem to be there.
Cheers,
Johan

Hi All,
Can I host elog in the web (internet) under windows platform (elogd.exe only) without Apache Web Server? If possible, what syntax should I add in the configuration file? Appreciate feedback. Thanks.
Cheers,

When you install elog under windows, an example config file gets installed which lets you do already what you want. Then you can extend the config file according to the documentation https://midas.psi.ch/elog/config.html
