Frontail is included in openhabian and can be choosen as an additional component.
You maybe have to reinstall it, if you have upgraded and are using openhabian.
Otherwise you would have to install it manually.
No.
log is empty, how can i fix it ?
thanks
do you have a logfile under /var/log/openhab?
Or is frontail still pointing to /var/log/openhab2
this log stopped yesterday night ( while updating from OH 2 to OH 3 )

yes correct but your log is showing the OH2 logging.
Also in your screenshot frontail is linked to /var/log/openhab2
Is this still the case?
yes , dunno why.
The Screenshot is what i get with:
http://openhab.local:9001/
dunno why its showing the OH2 Log in this directory.
the only way i see the current log is with Console → log:tail. but its a bit annoying.
try to remove frontail and install again via openhabian-config
I am currently struggling that i have only openhab2 logs and no /var/log/openhab
Frontail is pointing to the correct directory, but there are no files…
how to do so? and thanks for your help!
I have the same issue. Here my quick and dirty fix until we get a better solution.
Create a symbolic link for openhab.log and events.log like this:
/var/log/openhab2$ sudo ln -s ../openhab/events.log ./events.log
/var/log/openhab2$ sudo ln -s ../openhab/openhab.log ./openhab.log
Then stop the frontail service and restart the service
sudo service frontail stop
sudo service frontail start
Reload in browser
I’ve the same issue.
I found the file frontail.service in directory /etc/systemd/system
Here are two pointers to the old openhab2-directories:
[Service]
ExecStart=/usr/lib/node_modules/frontail/bin/frontail --ui-highlight --ui-highlight-preset /usr/lib/node_modules/frontail/preset/openhab.json -t openhab -l 2000 -n 200 /var/log/openhab2/openhab.log /var/log/openhab2/events.log
But this file is readonly nevertheless I’ve stopped the frontail service befor opening it with vim.
Does anyone know how to edit this file?
Did you open it with sudo ???
@hmerk You are true, and I’m a beginner in this sudo-stuff!
The frontail-viewer with http://192.168.178.56:9001/ is running now with correct openHAB3-logs.
Here is what I’ve done:
There are two more lines in frontail.service with “openhab2”. Does anyone know, if these also have to be changed?
great finding michael, thanks for your step by step guide.
This is my frontail.service

sadly it didn’t work for me. i also changed the “After=openhab.service”
in total there is 3 x “openhab2” in it, on my side.
how does yours look like ? thanks!
PS: for the follow ups, to Write and Exit the vim type “:” then you are on the end of the editor and see the “:” and now just type “:wq” ( write and quit )
:q
to quit (short for :quit
):q!
to quit without saving (short for :quit!
):wq
to write and quit@RiotMode You have a typo in your path to event.log, there is a superfluent „t“.
Regarding changing openhab2.service to openhab.service, check which one exists. If it is still openhab2.service, frontail will wait forever, cause no openhab.service is started at all.
Thanks for your help Hans-Jörg, i found the “status” command and get this:
[18:58:09] openhabian@openhab:/var/log/openhab$ sudo systemctl status openhab2.service
Unit openhab2.service could not be found.
[18:58:21] openhabian@openhab:/var/log/openhab$ sudo systemctl status openhab.service
