Plugin collects network metrics from /proc/net/netstat, /proc/net/snmp and /proc/net/snmp6 files

The plugin firstly tries to read file paths from config values if it is empty, then it reads from env variables.

• PROC_NET_NETSTAT
• PROC_NET_SNMP
• PROC_NET_SNMP6

If these variables are also not set, then it tries to read the proc root from env - PROC_ROOT, and sets /proc as a root path if PROC_ROOT is also empty.

Then appends default file paths:

• /net/netstat
• /net/snmp
• /net/snmp6

So if nothing is given, no paths in config and in env vars, the plugin takes the default paths.

• /proc/net/netstat
• /proc/net/snmp
• /proc/net/snmp6

The sample config file

[[inputs.nstat]]
  ## file paths
  ## e.g: /proc/net/netstat, /proc/net/snmp, /proc/net/snmp6
  # proc_net_netstat    = 	""
  # proc_net_snmp 		= 	""
  # proc_net_snmp6 		= 	""
  ## dump metrics with 0 values too
  # dump_zeros			= 	true

In case that proc_net_snmp6 path doesn't exist (e.g. IPv6 is not enabled) no error would be raised.
