check_drivesize, perf-config, extra(size)

[petitPeyre]

here is the command I use and the corresponding result.

check_drivesize show-all drive=C: "detail-syntax=(${drive}\\) size: ${size}, used:${used} (${used_pct}%)" "perf-config=used(unit:GB;suffix:used;prefix:'') used %(ignored:true) extra(size)"
L        cli OK: OK (C:\) size: 63.899GB, used:41.111GB (65%)
L        cli  Performance data: 'C:_size'=68611469312;0;0 'C:used'=41.11051GB;51.11952;57.50946;0;63.89941

to get rid of the drive name in the perf data, I add "perf-syntax=none" to the command

check_drivesize show-all drive=C: "detail-syntax=(${drive}\\) size: ${size}, used:${used} (${used_pct}%)" "perf-config=used(unit:GB;suffix:used;prefix:'') used %(ignored:true) extra(size)" "perf-syntax=none"
L        cli OK: OK (C:\) size: 63.899GB, used:41.111GB (65%)
L        cli  Performance data: '_size'=68611469312;0;0 'used'=41.11051GB;51.11952;57.50946;0;63.89941

it works for the used part but there is still an underscore in front of size
I also tried to have the metrics for size in the perf data in GB. I tried both size(unit:GB) *(unit:GB) in the perf-config string. it adds GB after the size but the value stays in bytes.

check_drivesize show-all drive=C: "detail-syntax=(${drive}\\) size: ${size}, used:${used} (${used_pct}%)" "perf-config=used(unit:GB;suffix:used;prefix:'') used %(ignored:true) extra(size) *(unit:GB)" "perf-syntax=none"
L        cli OK: OK (C:\) size: 63.899GB, used:41.111GB (65%)
L        cli  Performance data: '_size'=68611469312GB;0;0 'used'=41.11052GB;51.11952;57.50946;0;63.89941

any idea to remove the _ and have the size in GB is welcome !
