Log Viewer (frontail) with very less entries

Setup, Configuration and Use Runtime
1

Hello,

the Log Viewer (frontail) at port :9001 only shows the entries of the last 40 minutes.

Maybe I’m running out of RAM memory, but this would be surprising as only very less bindings are installed.

Is everything ok with my setup? Thanks.

It should not be log messages from the last 40min, but a certain number of log messages.

You can configure how many rows frontail will show by default when the UI is loading and how many rows frontail will show max while you leave the UI open.

Unfortunately I forgot where to configure this (sorry), have a look into the frontail docs.

On my system I see data for about 20minutes after a refresh! When the lage is just running it keeps older data as well, however there might be times with no data.
I don 't think that something is wrong with my system as well as yours.

Thanks, so frontail should be ok, only need to figure out how to change the number of log messages.

Is it also ok that only 50MB RAM are available?

Yes Linux does not release ram unless you need it, plus openhab uses the heap space.

It’s showing the contents of the current logfile. Has it been rotated 40 mins ago ?
