Logbook architecture and availability, posted by Frank Baptista on Fri Dec 14 15:46:14 2018

I have a setting which makes ELOG a perfect solution, but there's a situation that
I'm struggling to get my head around. We have 3 separate laboratories, each one containing a number of temperature chambers, which run almost constantly
over a number of shifts. Each temperature chamber has it's own logbook (laptop). So far, pretty simple. |

Sure that's easy. Install elog on each laptop separately, so they run without network. Then, set up a central elog server, and use "mirroring"
as explained in the documentation at https://elog.psi.ch/elog/config.html#mirroring
So when ever the entwork comes back, you execute a manual mirror operation, and your new entries will be pushed to the central elog server. |

Thanks Stephan! I guess I was making it harder than it is. I'm still a little fuzzy -- in this instance, am I correct in saying that each
laptop would be considered a "master", and the remote (network) server considered the "slave"? Also, I'm not sure quite sure
-- which server should be assigned responsibility for performing periodic synchronization between the laptop and the central elog server? |

I would call the laptops the "master" being responsible for pushing data to the central server which you can call "slave"

I tried to reproduce the problem but could not. The config file uses "emtpy.html", "filtermenutext.html" and so on which I don't
have. Same with eventlocation.
Rather than sending me all the files, can you strip down your elogd.cfg to a minimal version where you still see the problem. Then give me all |

I've got things working - sort of. Ran into one strange problem that has me scratching my head. I have two different laptops, each running
a local instance of their own logbook. Both are functional, but for some strange reason, one looks great, and the other is missing its graphic format.
I've attached a screen capture of that logbook, and a copy of the config file. Do you see something that I've done wrong? |

Sorry -- dumb mistake. I moved the "theme" files to the resource folder. Works like a champ...life is good!
