842acaef1a Prevent escaping of internal names with leading numbers to fix graph processing 
With serials like

Node             SN                   Model                                    Namespace Usage                      Format           FW Rev  
---------------- -------------------- ---------------------------------------- --------- -------------------------- ---------------- --------
/dev/nvme0n1     285S100HTYST         KXG50ZNV512G TOSHIBA                     1         512,11  GB / 512,11  GB    512   B +  0 B   AAGA4106
/dev/nvme1n1     S4GENX0N713949       SAMSUNG MZVLB512HBJQ-00000               1         474,89  GB / 512,11  GB    512   B +  0 B   EXF7201Q

the internal names (by serial number) were rewritten to

Field 	Internal name 	Type 	Warn 	Crit 	Info
/dev/nvme0n1 	_85S100HTYST_w 	derive 	  	  	 
/dev/nvme1n1 	S4GENX0N713949_w 	derive

--> the trailing underscore in case of nvme0n1 created problems in graph processing:

[RRD ERROR] Unable to graph /var/cache/munin/www/lxdserver/....agitos.de/nvme_bytes-month.png : undefined vname c285S100HTYST_r

Therefore I added a prefix 'SN_' for internal names.

c7299aeba2 nvme: add graph for spare capacity. add support for limits 
The default limits are sort of randomly chosen.  My nvme drives report
a warning level at 10% spare capacity, so I kept that here.

a420c4eb58 smart_: renaming the file 
The destination file is a wildcard one. Therefore the C file should be
named with a trailing `_`.

2fd3eec87c Hacked together a smart_ plugin in C 
There is some trickery going on to not wakeup the disk when it's in standby

Note: this was aimed at munin-c, but was rejected since it uses a
subprocess that calls the `smartctl` tool.

f90427c32a Update for extra fields in newer kernels 
The fields have changed from 11 or 15 on recent kernels but does not effect what the plugin gathers. 
See 5.4 https://www.kernel.org/doc/html/v5.4/block/stat.html versus 4.16 https://mjmwired.net/kernel/Documentation/block/stat.txt

Generate cache file if missing 
Don't exit with error if cache file is missing, instead refrain from sending values and daemonize() in an attempt to generate one.
Invocation using 'config' before generation is successful will fail, as mentioned in #914, but configuration will get picked up as soon as it is present.

37b533a5c3 Fix Odd number of elements in hash at linux_diskstat_ line 321 
Reading from /sys/block/*/stat does not provide the disk major and minor
numbers (versus reading from /proc/diskstats). When saving the disk data
back to a temp state file, these empty values for the disk major and
minor numbers get turned into undef values on state restore.

On the line: `my ( $prev_time, %prev_diskstat ) = restore_state();`

`%prev_diskstat` will 'slurp' up all returned values from the function
call (converting the list into key value pairs) but if one of last
values is from the major or minor number (which will be undef), the key
(major or minor) will be sent but the undef value will not be
sent. Hence this results in an attempted hash assignment where one of
the key values pairs is missing a value and thus the 'Odd number of
elements in hash assignment ' warning is thrown.
