There is a python API to access ELOG via HTTP: https://github.com/paulscherrerinstitute/py_elog

Lin Wang wrote:

We want to develop separate mobile web pages for the web applications deployed at CSNS accelerator, including the PSI Elog.

In Elog, is there RESTful API or HTTP/JSON or HTTP/XML interface for other web clients to access?

Or is there any workaround?

 

  69399   Thu Oct 21 11:00:46 2021 Warning Andreas Luedekeandreas.luedeke@psi.chBug reportLinux3.1.4-2e1708bRedirect in Execute new needs space after ">"

EDIT: forget the tip below. Instead just call script files: inline scripting in the ELOG config shows very strange behavior. Doing the same in external scripts works reliable.

 

I just spend an hour searching for a problem. To avoid others to spend the hour again, here's a little "special behaviour" of shell execution in ELOG you should know about:

If you want to do redirect to a file in a shell execution, put a space before and after the redirecting. The following does not work:

Execute new = if ! [ -z "$CampaignID" ] ; then echo "$CampaignID" >/usr/local/elog/logbooks/elog-campaign.default ; fi

You will not get an error message, but the file is not created. But if you add a space it will work as expected:

Execute new = if ! [ -z "$CampaignID" ] ; then echo "$CampaignID" > /usr/local/elog/logbooks/elog-campaign.default ; fi

It is not really a bug; if you know about it, then it is not a big deal: hence this entry here. I saw this behavior on a Linux RHEL7 system.

In case you are wondering: I use this to create a default for the field CampaignID, to be used for new entries in combination with a Preset:

Preset CampaignID = $shell( if [ -r /usr/local/elog/logbooks/elog-campaign.default ] ; then cat /usr/local/elog/logbooks/elog-campaign.default;fi )
  69400   Thu Oct 21 11:15:20 2021 Idea Andreas Luedekeandreas.luedeke@psi.chRequestAll3.1.4How about string constants in config files?

My config files are often large and use some shell scripting. In these shell scripting part I interact with files and execute scripts in specific folder.
It would be nice to have the ability to define for example a file path once and reuse it in different parts of the config file. It would help to make config files cleaner. For example:

Constant c_cid = "/usr/local/elog/logbooks/elog-campaignID.default"
Execute new = if ! [ -z "$CampaignID" ] ; then echo "$CampaignID" > $c_cid; fi

Preset CampaignID = $shell( if [ -r $c_cid ] ; then cat $c_cid; else echo None > $c_cid; echo None; fi )

If you need HTTPS then you must specify the "-s" option.

You could have looked into the help of the elog command:

"cat text | elog -h ... -l ... -a ..." or in a file with the -m flag.

Hello,

 

I am trying first time to use the tool /usr/bin/elog. From the documentation is not clear to if everything must be in quotes or not, if every attribute requires -a.

Here is how my attempt looks like (changing actual data by fake one):

      /usr/bin/elog -h elog-1.matrix.com -l LogBook -u jcaballero mypassword -a Team='Team Name Here' Category='Category Here' -a 'Affected service'='Name of affected service here' -a Criticality=Normal -a 'Oncall Documentation'='No modifications required' -a Subject='here is the subject line' 'here is the text'

I just get "Error transmitting message". 

Attributes Team and Category are of checkbox type. Attributes Criticality and Oncall Documentation are of radio type.

What is wrong with my command attempt?

 

Thanks a lot in advance.

Cheers,

Jose

But this is real progress! Now elog successfully connected, and all your data was transmitted, but elogd refused your content.

A possible explanation is that one required attribute of this logbook was not provided in your elog command, or that one value of an attribute does not match any allowed value for that attribute.
Here we can only help if you post the config of your logbook.

Cheers, Andreas

PS: you did not provide the -s option?!? Just in case you lack the knowledge: providing a port number 443 does not imply the use of the SSL protocoll.

If you use HTTPS, you have to connect to port 443 of your server, using the "-p" option.

Furthermore, you run under an Apache server, right? How do you do the redirecting to elogd? I guess you specified a subdir in the URL named /LogBook to redirect to elogd. The you use another part of the URL to select the logbook, which again might be "LogBook". Is that correct? So your full URL in the browser would be https://elog-1.matrix.com/LogBook/LogBook. If that's the case, you have to tell the elog tool that you use a subdir in the URL using the "-d" option.

It is the default. If you install ELOG on your PC and run it, then every access will be directly to the ELOG web service. If you want to have Apache inbetween, it is some extra effort.

I am no Windows expert. An option is to write your own application and use the "elog" command to post the output of the application to your ELOG.
There is as well a python library to access ELOG via http: https://github.com/paulscherrerinstitute/py_elog

Now you've totally lost me.

elogd is a web service. You connect to it with a web browser. You don't pass arguments at startup of the service that refers to specific atrributes. I have no idea what you intend to do, you need to explain a lot more.

Jose Caballero wrote:

Hi Andreas,

I realize from your response that my question was not clear. I was not asking how to get it. Note that I am just a regular user, I am not the administrator of the service.

My question was about how to use it. From the man page, or from the explanation in the Administration Guide, it is not clear to me how to pass the same arguments I have been trying for /usr/bin/elog. For example, how to pass the list of attributes. I don't see a "-a" option for elogd. 

Thanks.
