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