Yes. The rule of thumb is that currently elog runs fine for a few 10000 entries. At 100000 entries it starts getting slow. I have already in my to-do list the task to improve the performance for large databases, and I have a rough idea where the bottleneck is, but I pushed the priority low because not many people have large databases right now (but it might change in the future). How many entries do you have? (It's not the size of the entries, but the number!)

Hello

To test elog i created a very large databasefile ( 071006a.log = 39MB ) via an import.
Nothing special. At the import I already got a message to increase "Max content length" to 22420822 in the global section. Below is the what i've done. There are no attachments involved, as you can see.
[global]
port = 80;
Max content length = 22420822
[DAP]
Theme = default
Attributes=Klant,Doc
Quick filter = Klant

So there are only 2 user defined fields in the database.

I ended with 125384 entries like the one above.

Everything works fine but ......... [U]tteerrrriibbllee[/U] [B]slow[/B].  CPU usage is constant at 99%.  

I tried to split the one file produced by the import into 2 chunks but that did not improve the situation.

My question is : Is there a rule of thumb for the size of the "database" in which elog keeps it's performance, or better : is there a solution for this for elog.

There is already a time and a date stamp. If you look in the logbook directory, you see attachments preceded with the date and time when they were submitted. You can see this date/time when you click on the attachment, such as in

http://midas.psi.ch/elogs/Config+Examples/040519_000348/elogd.cfg

where you will see it even in the URL (May 19th, 2004, 0:03:48) in the above case. I agree that this is not so obvious. If you make a proposal where this date/time should be displayed, I can easily add it.

Hi,

Been using ELOG for a couple of years now and I am very impressed with its functionality.

I would like to request a new feature - add date and time stamp to file upload. We use ELOG (amongst other things!) as a change log and this would really allow allow more accurate records to be kept. For instance we upload router config files (to record changes)and having the exact upload date would be a big enhancement, especially when there are a lot of attachments.

Many Thanks in Advance
Fergus

Yes. Fixed in Revision 1930.

So the list is shown to the one requesting the registration? Would it be possible to have an option that, when selected, simply did not list any logbooks? I can see a customer becoming confused if they did not see their logbook listed. Just turn off the selection completely. Otherwise, this will work but I fear will generate more questions as in "Why isn't logbook <blah> listed?"


I agree, that's inconsistent. So I removed the logbook list completely (SVN revision 1914) and added a note on the user notification that they should click 'config' to subscribe to any logbook.
