show the BSC log output on the screen when there is
activity
This?
sudo journalctl -u osmo-bsc -f
The fine art is to adjust the logging levels so that you see enough
information, but not too much.
Just as an example from osmo-bsc.cfg:
log stderr
logging filter all 1
logging color 1
logging print level 1
logging print category 1
logging print category-hex 0
logging print file basename last
logging timestamp 0
logging print extended-timestamp 1
logging level set-all info
logging level linp notice
logging level lss7 notice
logging level lsccp notice
logging level lsua notice
logging level lm3ua notice
There are many other ways to configure logging, see the alternatives
'log stderr', 'log file', 'log gsmtap'...
