* remove redundant meta labels from SCSI metrics * added `smartctl_device_nvme_capacity_bytes` metric * for some devices, such as 2.5" NVMe Intel & Micron the `family` field may be empty The `.user_capacity` exists only when NVMe have single namespace. Otherwise, for NVMe deivces with multiple namespaces, when device name used witout namespace number (exporter case) `.user_capacity` will be absent ``` smartctl --info --health --attributes \ --tolerance=verypermissive --nocheck=standby --format=brief --log=error \ /dev/nvme11 --json | jq '.user_capacity' null smartctl --info --health --attributes \ --tolerance=verypermissive --nocheck=standby --format=brief --log=error \ /dev/nvme11 --json | jq '.nvme_total_capacity' 3840755982336 ``` Signed-off-by: Konstantin Shalygin <k0ste@k0ste.ru>
