ELog does not use the Log4j library so no issue there. If you run a web server like Apache in front of ELog, you however have to check if you use log4j there.

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.

Is there any potential impact/concern with the Log4j exploit in Elog applications?

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

Hello,

I am interested in finding a preferrably single-click way to capture a screenshot and posting it automatically to a new elog entry . I would be doing this from Windows. Is this possible?

Thanks

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.

Nope. How? Is it documented? 

Have you tried to connect directly to elogd and not going through Apache?
