With the concerns about your bash prompt registered...

btrfs filesystem show

... is a good choice.

If you have multiple filesystems you can point show at a device/
mountpoint/label/UUID to get the output for just the one.

You'll want to pay particular attention to the individual device lines.  
Of course you can grep/sed/otherwise-process that down to a single line 
if desired.

If btrfs filesystem show says it's close to out of room, run btrfs 
filesystem df for more info.  There's lots of information on the wiki and 
in various threads here about interpreting the information these commands 
output (it takes both commands to get a good picture, but show is good 
for brief summary, provided you know to look at the device lines not the 
overall total line), and what to do when necessary to return some balance 
to the situation.
