Updating my toolbox.  Starting to use elog as, well, a logbook.  Kind of liking the short, sweet, to the point capabilities.

Which leads me to wonder if anybody has opinions on trouble ticket systems that work well with elog?

Thanks!

 I use elog's built-in ticketing system, and use the auto-generated ticket number to cross-reference with other matters/documents/files.  Much of the documentation for tickets is rather buried away under Subst <attribute> = <string>.

I've not found a way to link from an entry to a set of entries in another thread by their ticket number, particularly across more than one logbook.  [This is possible via their elog entry number, and which logbook it is in].  The former would be usefil to cross-reference an incident which you identify external to the elog system - "Oh, it's another one like [Ticket no] NOV12-001" possibily easier than "Oh it's another one like elog:archive12/67142 ".  Oh, the last bit should be highlighed as a (non-existant) link here, to show my point, nice of the ticket could be as well.

On the plus side, you can arrange the ticket number to show up in the thread display, quick search by ticket number, run different ticket colours (as it were) in different logbooks (i.e. different prefixes).  Just ensure you don't archive the latest entry, as that can lead to duplication of ticket numbers.

 

 By "ticket number" are you referring to the Message ID, or is there some additional trouble ticket functionality buried away?  And... can you point me to the documentation that's "buried away under Subst <attribute> = <string>?  Thanks!

Message ID is the internal numbering of each entry.  It is the number that is used internally for generating the threads, and which you can reference with the elog:[message ID] code within an entry to cross reference the entry with that message ID.

"Ticket" is the name of an attribute.  You define the attribute "Ticket", and can preload the attribute with the format  you require(*).  In the following extract of an elog.cfg file are the relivent lines to generate tickets, show the ticket number in the thread display, search for a particular ticket, and allow it to be edited when writing an entry - there are reasons.  The attribute "Organisation" here is an example of another attribute you would enter with the initial entry, of course there will be others specific to your requirements.

Attributes = Ticket, Organisation, ...

Preset ticket = T#####

Thread display = $Ticket: $Organisation, ...

Quick filter = Ticket, ID

 

When you start an new entry, the Ticket attribute is prepopulated with a number.  The first time will be T00001, subsequently it will be one higher than the currently existing highest ticket number in the logbook.

Why might you edit the ticket number?  You may wish to go back and edit an old (complete) entry's ticket number so it has some obvious name - perhaps the solution of what proves to be a stock problem, that has become known by a pet phrase, so it can be found by searching for that phrase in the quick fillter "Ticket".  That is a more advanced use of the ticket system.

 (*) Further on the format of the ticket is in the documentation under Subst <attribute> = <string>

Sorry for multiple edits, why cannot I cross-reference an entry in this forum as I can in my local logbook?

 

Thanks for the additional details!

I'm using Kerberos and SSL and experience problems with individual setting of "Login user =" for different logbooks.
Sometimes (not every time, but most times) the server crashes under the following condition:
When I login at one logbook and then change to a logbook, that has a restricted "Login user" list with my login
name not in it. It created the following GDB output:

Program received signal SIGSEGV, Segmentation fault.
show_elog_list (lbs=0x916b768, past_n=0, last_n=0, page_n=0, default_page=1, info=0x0) at src/elogd.c:19793
19793         message_id = msg_list[index].lbs->el_index[msg_list[index].index].message_id;

Expected behaviour would be to show me the login page with the error message:
"you don't have access to this logbook".
This message is never shown for the attached configuration file.
If I remove the "Guest" commands for logbook "TestB" then elogd behaves properly.

For the moment I've just disabled "Login user" settings.

That's a feature

In the summary view, I cannot use any HTML code, since it will screw up the table layout. Therefore elog searches for any "<" and ">" pairs and removes the text in between. In principle one could do a better job, but I do not want to write a complete HTML interpreter just for that purpose.

 Well, this is a choice. But if the encoding of the entry is 'plain', you could just avoid checking for embeded HTML. We use the summary view constantly for our main experiment logbook. Thanks anyway.

Ok, I fixed that in revision 2442.

When I run a mirror server and both logbooks using SSL/KRB5 then the cron job causes a segmentation fault.

I haven't tried to check it with a simple configuration yet.
My set-up: two elogd on same server, one running "german" on port 444, the other "english" on port 445.
Both are behind an apache webserver configured reverse proxy, to hide the ports for external access.
I'll try to reproduce the fault with a "minimal configuration" soon and report again.

I've tried to test a simpler configuration on my local PC but failed:
all simple set-ups I've tried worked fine.

I found that the mirror cron synchronization works fine in my production set-up when I remove the line:
Mirror user = luedeke

But I can have this line in my simple test set-up and it still works fine.
Anyway: bugs closed for me.
