Logs in mechine langauge

and some .gz files. Can any one help to how to get logs in readable format

.gz Files are zip compressed files. You can open it e.g. with zcat.

I think it is also possible to change to log format to JSON.
But the gz compression must stay, otherwise the logfiles would eat to much space.

hi i am getting auth.log, auth.log.1 and auth.log.2 only

Not getting CWMP, NBI,FS and UI logs

In addition to zcat, you can also use zgrep, zdiff, zless, zmore
