I'm converting our on-call logbook, with 25 years of history, to elog. Is there a way to override the current date/time for the Date field with the creation date/time of the original logbook entry?

You have to manually manipulate the logbook files YYMMDDa.log where you find the date at the top like:

MID@$: 1
Date: Wed, 02 Sep 2020 15:38:09 +0300 <==== change here !!!!

Hi Stefan, thanks! Does the Date field need to be the first field in each entry? I can see adding a "termpory" field called "Orig Date", upload the old entries, then edit the file(s), delete the Date field, and rename Orig Date to Date. Will that work?

"Date" must be on the first line on each entry and it must be named "Date".

Stefan

You could transform your entries into the ELOG file format (either XML or CSV) and then use the import function. That would upload the correct dates from your entries.

If you use the "Orig Date" trick you've proposed, you'll see that datetime fields are stored as seconds of the epoch (since 1.1.1970). Not so easy to copy and paste them, but you can convert them with a script.

Cheers, Andreas

Hi Andreas,

Thanks for your input! After a little testing, it appears that if I make "Orig Date" the first field, it will fall under the Date field in the logbook file. I can then do a global delete of Date:, and replace Orig Date: with Date:, leaving it as the first field in the entry. Then I can delete the Orig Date field.

Hi David,
correct. And in addition you will need to convert "Orig Date" from seconds-of-the-epoch into a properly formated date string (see example below from Stefan) ...

Andreas

Hi Andreas,

It was actually easier than that. The time stamps in the old system were in epoch format, so when I created the new record, (my conversion program was written in Python), I simply formatted that value in the format Stefan pointed out below, and defined the Orig Date field as text. Then I was able to munge the logbook file with 2 global editor commands, and it worked perfectly. Thanks again!

Hello,

I'm new to elog software and I could not find a solution to my configuration issue. I would like to setup a configuration file similar to MEG experiment's elog.

https://elog.psi.ch/elogs/meg/

I'm interested in creating similar to the structure: "General", "Collaboratoin", "Sub-groups (with sub-sub groups "Software", "Hardware" etc). I cannot tell if this was created by using Top Group feature.

Can someone explain how this design structure can be achieved?

Thanks,

Daniel

It was done using the "groups" feature:

Stefan

All,

I would like to know if there is a way in elog to populate a field based on the value of another field. What I want to do is have a field with a few selections (a menu) and another text field that populates based on what I select from the menu.

Is this possible?

Look in the manual under "conditional attributes"

Stefan

Thanks for your suggestion. Right now, my log is configured as follows:

Options Eyepiece = Pentax{a}, TeleVue{b}, Meade{c}
{a} Options Pentax = 5mm, 20mm, 30mm
{b} Options TeleVue = 7mm Nagler, 10mm Radian, 24mm Panoptic
{c} Options Meade = 8.8mm UWA, 14mm UWA, 26mm QX

If I select "Pentax", I would like the other two options to be unavailable. Instead, all three options are shown. Can I mask the other unused options?

Instead of using three different options you could use the same:

Options Eyepiece = Pentax{a}, TeleVue{b}, Meade{c}

{a} Options Form = 5mm, 20mm, 30mm
{b} Options Form = 7mm Nagler, 10mm Radian, 24mm Panoptic
{c} Options Form = 8.8mm UWA, 14mm UWA, 26mm QX

It makes more sense.
But it is as well possible to supress attributed in the edit from. See

• Show Attributes = <list>
  Attributes present in this list are shown in the single entry page. Omitting attributes can make sense for attributes which are automatically derived from other attributes via the Change <attribute> command.
• Show Attributes Edit = <list>
  The same as Show Attributes, but for the entry form.

You just have a different <list> for each conditional case {a} {b} {c}.

I'm running  Elog version V3.1.4-ba84827 on Red Hat Linux 7.9. As part of migrating from an older in-house logbook to Elog, I need to upload all the old logbook entries. However, when I attempt to do that with the "elog" command line tool, I'm getting the error "command Submit not  allowed.

I read through a similar report from 2015 (entry #68149), but none of the potential causes seem to be at play here. The logbook is using PAM authentication, and I can log in to the web interface using the same credentials I'm using from the command line. The other case mentioned a dis-allowed encoding format, but my logbook is configured to allow all formats.

This is the command line I'm using:

/usr/local/elog/bin/elog -v -h logbook.aps.anl.gov -p 8081 -l On_Call -x -n 2 -a Date='10/19/2020 01:02' Author="David Wallis" Title='Test Upload' Status='Open' System='On-Call' -u 'wallis' '*****'  "This is a test message"

Update: I tried switching the logbook to no authentication reqiured, and still get the "command Submit not allowed" response.

"submit not allowed" you typically get if there is a "guest menu" for read-only access and you are not logged in. I never tried the elog program with PAM authentication, but you said that your turned authentication off. What I would do is to strip down your elogd.cfg to a very simple form until the elog utility works, then figure out which configuration makes the trouble.

Stefan

Hmmm... I added "New" to the Guest menu list, and the button showed up for a guest user. But when I submitted the new ticket, I got the message Error: Command "Submit" is not allowed for user ""

Giving up. Send me your config file and I will debug it.

Stefan

I've been able to work around this by completely turning off authentication, and adding New to the Guest menu list.

One additional question: since I'm uploading historical logbook entries, is it possible to set the entry creation date via the command line? It seems that elogd is overriding the attribute "Date".

FYI, I had problems a few weeks ago trying to get the command line elog working, blamed everybody and everything but myself.

In my case it was command line syntax errors and eventually got it going as part of a nightly script

While testing I ran the Elog Server from the command line in verbose mode to see if that helped determine the problem.

On the server end the logbook uploading to is set for Plaintext

# Set entries to TEXT Only format
Default encoding = 1
Allowed encoding = 1

Elog server authenication is standard built in to elogd, no PAM, no LDAP, no Kerberos 

Below is what works for me, I’ve replaced my Elog Server Hostname, Elog Username & Password used to connect to the server with generic.

Elog Server version = elog-3.1.4-2

# Log details in Elog Server

/usr/local/bin/elog -h HOSTNAME -p 80 -l Backups -u USERNAME PASSWORD -a Backup=NightlyBackupScript -a Hostname=$HOST -n 1 -x -m /tmp/elog.nightly.script.$TIMESTAMP

I've been caught out in the past having a very old version of the elog command line talking to a recent Elog Server build or Encoding not matching

Hi David, thanks for your input!

This logbook has been around for almost 10 years, and has evolved from file-based authentication, to LDAP, and finally to PAM (that can use any of local password files, LDAP, and Active Directory), and I'm thinking that might be the root of this problem. There are old account entries from the file-based days, with passwords, that match the AD usernames. I'm wondering if elogd is trying to use the password in the password file, rather than via PAM. I don't remember the old passwords, so I can't check, and I've run into problems trying to change the passwords. I'm wondering if there's a way to generate a new password from the command line, that would allow me to test the theory.

Hello,

How can one add an attachment to a new or existing entry with py_elog?
E.g. if I want to upload an image.

Thanks for the help!

Dear colleagues,
Can someone compile an up-to-date windows-version or write a manual how to do it in Windows without compiling errors?
Thank you.

Hello,

I'm working on new logbook and in one category I'll have many attributes (many more than in attached screenshot).

So here is my question. Is it possible to visually group such attributes with some border, or something like that?

In screenshot you can see what I want to achieve.

Best Regards

Daniel

Nope, this is not possible. Sorry.

Stefan

Our Unix server died, so we decided to move our old eLog to the new server, running Mac OSX. Elog version is earlier then 2013, I can not say

I read that on OSX  eLog must be intalled through "make" command

if I need to install eLog first, how to add all old information later?

• you need to copy your logbooks into the "logbooks" directory.
• you need to copy your elog.cfg logbook config file to the new elog folder and reference it at start-up (something like "elogd -c /usr/local/elog/elogd.cfg ...")

Some people modify other stuff (CSS, java scripts) but if you had you would know what you did.

If the old ELOG was a 2.x version and the new is 3.x, then on the first start-up all logbook data files are copied into sub-folders for each year.
This is only done (automatically) during the first start-up, afterwards you can not use a 2.x version anymore (you won't want that anyway).
