This problems have been fixed in SVN revision 2135.

Hi Stefan,

Is it possible to derive the time in a 'date/time' attribute from the Elog server?
We would like all our entries in GMT/UTC time and unfortunately as the time is currently derived from the client machines there are often entry descrepancies if the regional settings are not set correctly.

The '$entry time' variable can be used but seems to put a 1970 date in the field so bears no relevancy to an 'Event' time?

I'm also having issues with conditional entries in the Find page. If a conditional statement is used to hide attributes or change displayed attributes in the entry page then the attribute that is used in the conditional statement is not permanently selectable in the 'Find' page. It is available as a choice but as soon as selected the conditional action removes it? Is it possible to make conditional options/actions in the 'Find' page optional?

Hope that makes a little sense?

Many thanks

 

There are several methods to get the server time:

 

Via presets of attributes

Attributes = Author, Event time, ...
Preset Event time = $utcdate

which gives you actually the UTC time.

 

Via the editor

The editor toolbar contains a little clock. If you click on it, you insert the current server time (but localized, not UTC).

 

Hope one of the two methods work for you.

The problem with the conditional attributes in the find page is I believe fixed in the current version.

Originally, all information about our machines was stored in a spreadsheet with one sheet for the hardware of the machines and one for the software. By now, I've sucessfully moved the software part to an elog logbook and am now looking at transferring the hardware part as well.

As both lists are machine-name based, one of the options would be to merge both lists, as this would place all machine-related info into one logbook. The downside of this is that I get so many columns in list view that the result is quite unwieldy. Hence, I would like to hide some columns - ideally creating a "hardware view" and a "software view".

From the documentation, the only option I could find that seemed suitable was "List conditions". Unfortunately, I do not quite understand from the manual how this is supposed to work, so I'm quite possibly doing something wrong. I've tried this:

; General settings
List conditions = 1

; Attributes
Attributes = Type, Created, StatusA, StatusB, Archived

; Options & Tooltips
Options Type = Type1{10}, Type2{11}

; Conditionals
{10}List display = Edit, Type, Created, Status
{11}List display = Edit, Type, Created, StatusA, StatusB, Archived

but no matter how I set "Type", it does not seem to have any effect on the List display. One thing I don't understand for example is how does elog decide in List view which entry sets the condition? If all entries are set to the same value (in this example e.g. "Type1")? The first entry? Or am I missing something altogether?

Also, if there are alternative ways how I could accomplish my goal, I'd also be most grateful for suggestions.

Thanks in advance,

Thomas

 

 Indeed you got something wrong. The conditional attributes are meant for the input form, so you can turn some attributes on and off or choose different options for an attribute depending on the value of another attribute.

The only way I see how you can achieve what you want is to define two separate logbooks, but serve them from the same directory (via the "Data dir" option). Both logbooks should share the same attribute definition, but use different "List display" options.

Hi Stefan.

I have been "playing" around with this great tool and found an interesting "issue" ...

I use multiple logbooks and have both "Protect Selection page = 1" and "Expand Selection Page = 1".

When I open my elog, I get a Standard Login Screen with the Standard Bottom Text "ELOG V2.7.5-2130" which will link to your this website.

When I "Logout" and "Login" again from the Logbook page, I get another Login Screen with my own "Bottom text login" which will link to my own elog page.

How can I apply my own Bottom Text to the Standard Login Screen ?

Thanks & Regards, Barend
 

 

 By using the configuration option "Bottom Text Login = ..."

We've been having toruble with uploads not working and I notice that every time someone uploads to our elog the same error message appears in /var/log/syslog:

Cannot restore original GID/UID.

How can I fix thsi error? Or, perhaps more importantly, could it cause elog to "lock up" (note, it doesn't crash)?

I'm runing elog on Ubuntu kernel version 2.6.24-server.

 

 Probably something is wrong with the account under which you run elog. Normally (at least if you install elog from the RPM) you have an account "elog" and group "elog" under which you run elogd. You compile and install elogd under root (so that it can bind to port 80 for example), and then you put 

usr = elog
grp = elog

into the configuration file. So when you start elogd, it binds to the server port, then falls down to user "elog" and gives up root privileges. If the elog account for example does not exist, you get the above error message. The only problem I see there is if elog stays as root, it can do more harmful things in case it misbehaves.

Stefan,

I have defined the "Bottom Text Login = ..." in each Logbook Configuration section. But when I use this option in the Global Section, ELOG fails to start.

 That's strange. I just tried myself following configuration file:

[global]
port = 8080
Bottom text = <center>Hello</center>
Bottom text login = <center>Login Hello</center>
Password file = passwd

[demo1]
Comment = General linux tips & tricks
Attributes = Author, Type, Category, Subject
Options Type = Routine, Software Installation, Problem Fixed, Configuration, Other
Page Title = ELOG - $subject

[demo2]
Comment = General linux tips & tricks
Attributes = Author, Type, Category, Subject

and everything works fine as can be seen from the login screen:

so can you check if above file works for you?

Many people want conditional attributes on the find page, so I cannot remove it. Before adding another parameter to disable this optionally, I would like to ask you to first try the "Show attributes edit = ..." option, which is not evaluated in the "find" page. Maybe you can achieve what you want with this option.

A problem recently developed for our elog...after running without much problem the elog daemon was restarted on an ubuntu server running apache2. Now the server gives 502 Proxy Error messages:

 

Proxy Error

The proxy server received an invalid response from an upstream server.
The proxy server could not handle the request GET /elog.

Reason: Error reading from remote server

I did a force-reload of apache after making sure the modules are enabled. I also restarted elogd but to no avail. One symptom seems to be that the GET request is empty...that is before it was:

"GET /elog/sample_elog/etcetera HTTP/1.1"

but now it is just

"GET /elog HTTP/1.1"

 

Just started out of the blue...

 

Any ideas?

 

 I have a similar problem when I restart the elogd daemon. To fix that, I usually also restart Apache.
