Domoticz

Hello
it seems that the OZW_Log.txt file is reset only during a reboot of DOMTICZ.
Can we reset this file manually or via a script?

Hi,
What do you mean by reboot. Stop/Start/Restart only Domoticz or complete reboot of RPi or other device?

In case of complete hardware reboot, try a restarting Domoticz only. If that also "recycles" OpenZWave log, search the forum for logrotate.

A few and i wrote working samples to rotate (reduce/compress/recycle) domoticz logfile.



Grtz,

Hello,
I just want to know if I can, safely, empty the file manually.

yes you can, if you have Z-Wave debug enabled disable it for a much smaller file.

you can empty it safely with this:

truncate -s 0 OZW__Log.txt

I have /var/log in tmpfs and OZW_Log.txt, ozwcp.poll.XXXXXX.xml and ozwcp.topo.XXXXXX hardlinked there. Saves quite some writes to the SD.

I did a test.
If I empty the file, manually without restart Domoticz, it remains empty and is not incremented by the errors as normally.
it seems that the only solution is to restart Domoticz.
I have not found if there is a "Logrotate" associated with that file.

As soon as you touch it, even a single line, the file is blocked and recorded more errors.
I have to restart Domoticz.

try sending a SIGHUP signal to domoticz instead of a hard restart.. thats how my logrotate scripts force domoticz to start a new file.

I do not know how to do it.
I comprises the use. How to make this call in a shell script run by cron or if the file exceeds 5000 lines for example.
What files are then revived?
I'd rather be alone OZW_Log.txt revived.

i think this will only work for the domoticz log file

Valdoison:
You are probably debugging something with OZW, otherwise you did not enable it to log.
When your done, just turn off debugging

Just tried it again with "truncate -s 0 OZW__Log.txt"
File is emptied and starts filling automatically without any other action.
