In some cases the file might be called "temp" instead of the usual format "temp<index>_<item>"
as described in the kernel docs: https://www.kernel.org/doc/Documentation/hwmon/sysfs-interface
In this case, treat this as an _input file containing the current temperature reading.

Starting with (not yet released) OpenBSD 6.4, sysctl KERN_CPTIME2 will
return ENODEV for offline CPUs.
SMT siblings are reported as offline when hw.smt is disabled, which is
the default since one of the later Spectre variants. So this might
affect a few systems.

Add metrics that expose more information about MD RAID devices and
disks:
- the RAID level in use
- the RAID set that a disk belongs to
This allows for things like alert on unusually high I/O
utilisation for a disk compared to other disks in the same RAID set,
which usually means the disk is failing, and for comparing
write/read latency across RAID sets.
Output looks like:
node_md_disk_info{disk_device="/dev/dm-0", md_device="md1", md_set="A"} 1
node_md_disk_info{disk_device="/dev/dm-3", md_device="md1", md_set="B"} 1
node_md_disk_info{disk_device="/dev/dm-2", md_device="md1", md_set="A"} 1
node_md_disk_info{disk_device="/dev/dm-1", md_device="md1", md_set="B"} 1
node_md_disk_info{disk_device="/dev/dm-4", md_device="md1", md_set="A"} 1
node_md_disk_info{disk_device="/dev/dm-5", md_device="md1", md_set="B"} 1
node_md_info{md_device="md1", md_name="foo", raid_level="10", md_metadata_version="1.2"} 1
The `node_md_info` metric, which gives additional information about the
RAID array, is intentionally separate to avoid adding all of those
labels to each disk. If you need to query using the labels contained in
`node_md_info`, you can do that using PromQL:

I looked at adding the array UUID, but there's no sysfs entry for it and
I'm not sure there's a strong use case for it.

Add these metrics as a textfile script rather than adding them to the Go
