Are you running node_exporter in Docker?

no

What did you expect to see?

node_drbd_*

What did you see instead?

nothing, its not parsing the drbd stat file

i use the same drbd stat file, looks it working well:

{"device":"drbd1","level":"debug","msg":"numerical value","value":0}
{"device":"drbd1","level":"debug","msg":"numerical value","value":130077164}
{"device":"drbd1","level":"debug","msg":"numerical value","value":130077164}
{"device":"drbd1","level":"debug","msg":"numerical value","value":0}
{"device":"drbd1","level":"debug","msg":"numerical value","value":8}
{"device":"drbd1","level":"debug","msg":"numerical value","value":0}
{"device":"drbd1","level":"debug","msg":"numerical value","value":0}
{"device":"drbd1","level":"debug","msg":"numerical value","value":0}
{"device":"drbd1","level":"debug","msg":"numerical value","value":0}
{"device":"drbd1","level":"debug","msg":"numerical value","value":0}
{"device":"drbd1","level":"debug","msg":"numerical value","value":1}

and do you have the same data in the /proc/drbd? Maybe it has something to do with the configuration.

i use your /proc/drbd output content and here is my test，it seems it works. can you show the full drbd metrics content ?
key:cs value:Connected
key:ns value:0
key:nr value:2580152
key:dw value:1091301156
key:dr value:0
key:al value:8
key:bm value:0
key:lo value:0
key:pe value:0
key:ua value:0
key:ap value:0
key:ep value:1
key:wo value:f
key:oos value:0

not sure what was I doing, but it seems to be returning with the correct metrics now. thank you for spending time with it!
