I am trying to figure out how to drop some data out of librenms. I am using the smart plugin to get data from a FreeBSD NAS (FreeNAS), but the graphs in librenms display some garbage data:
The output of the smart plugin looks good:
root@mediastore:/mnt/sirius/homes/snmp # ./smart

da17,0,0,null,null,null,null,null,null,null,35,0,0,0,0,null,null,0,0,0,0,0,0,0,0
but in the graphs, I see some perl garbage metrics:
All Drives | drives: ada0, ada1, da0, da1, da10, da11, da12, da13, da14, da15, da16, da17, da2, da3, da4, da5, da6, da7, da8, da9, env__, env__perl__No_such_file_or_directory, env__smartctl, env__smartctl__No_such_file_or_directory
Since the output of the command looks ok, I think the metrics are reported correctly (there may have been an issue in the past) but how can i get rid of the “env_perl_no_such_file_or_directory”, etc lines so only the drives show up?

I tried dumping the mysql database and grepping for " env__smartctl", but no matches came up, leading me to believe this might be a rendering issue and not a database/data issue?
root@ubiquiti-docker:~# grep env__smartctl /tmp/sql.sql

Thanks!
