      Description

      In template "Template Module Linux network interfaces by Zabbix agent" we define a macro:

      {$VFS.DEV.DEVNAME.NOT_MATCHES}
      

      with value:

      ^(loop[0-9]*|sd[a-z][0-9]+|nbd[0-9]+|sr[0-9]+|fd[0-9]+|dm-[0-9]+|ram[0-9]+)
      

      As we can see, we try to filter out drive partitions for very/most popular block devices names, to monitor only block device itself.
      I.e. we discard "sda1" or "sdb3" etc.

      But there are other quite popular block device types, which use different names.
      For example on my laptop and on my raspberry, in /proc/diskstats I have these guys:

      and I have all those partitions discovered too, while it's redundant.

      So, the macro should be extended to include at least these popular drive names.

      I'm not sure about naming pattern in case if I have several same type block devices (quite possible for nvme***), so maybe we could filter *out not by "start of line", but by "end of line".
      So I suggest this value for the macro:

      ^(loop[0-9]*|sd[a-z][0-9]+|nbd[0-9]+|sr[0-9]+|fd[0-9]+|dm-[0-9]+|ram[0-9]+)|(p[0-9]+)$
