Use of elog inside Phoebus

[Andrea Celentano via Tech-talk <tech-talk at aps.anl.gov>]

Dear colleagues,

I am trying to use the elog application inside Phoebus. The details I found about this are in these slides: https://indico.fhi-berlin.mpg.de/event/52/contributions/564/attachments/222/683/phoebus-elog-client.pdf

I did the following:

1. I compiled phoebus from scratch with maven (master from gitlab), adding the elog application to build.xml

    <ant dir="app/logbook/ui"/>

    <ant dir="app/logbook/elog"/>       —-> My addiction

    <ant dir="app/log-configuration"/>

 

2. I checked inside my elog installation to read the password:

 <password encoding="SHA256”>My password</password>

3. I added the following to my settings file:

org.phoebus.logbook/logbook_factory=elog

org.phoebus.logbook.ui/logbook_factory=elog

org.phoebus.elog.api/elog_url=http://my_elog_host:8080/Main

org.phoebus.elog.api/username=shift

org.phoebus.elog.api/password=My password

org.phoebus.elog.api/categories=Info, Problem, Shift summary, Data quality, Micromegas, ECAL, MasterTime, MSADC 

org.phoebus.elog.api/types=

When I start Phoebus with ./phoebus.sh -settings my_settings.ini and I open the logbook, I get the following error:

2025-04-26 10:37:40 INFO [org.phoebus.logbook.olog.ui.LogEntryTableViewController] Single search: *

What I do not understand is why the “olog” app is referred to in this error, since I am not using it at all..

Thanks,

Bests,
