## Nstat input plugin ## Nstat input plugin
Plugin collects network metrics from ```/proc/net/netstat```, ```/proc/net/snmp``` and ```/proc/net/snmp6``` files Plugin collects network metrics from `/proc/net/netstat`, `/proc/net/snmp` and `/proc/net/snmp6` files
### Configuration ### Configuration
The plugin firstly tries to read file paths from config values The plugin firstly tries to read file paths from config values
if it is empty, then it reads from env variables. if it is empty, then it reads from env variables.
* ```PROC_NET_NETSTAT``` * `PROC_NET_NETSTAT`
* ```PROC_NET_SNMP``` * `PROC_NET_SNMP`
* ```PROC_NET_SNMP6``` * `PROC_NET_SNMP6`
If these variables are also not set, If these variables are also not set,
then it tries to read the proc root from env - ```PROC_ROOT```, 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. and sets `/proc` as a root path if `PROC_ROOT` is also empty.
Then appends default file paths: Then appends default file paths:
* ```/net/netstat``` * `/net/netstat`
* ```/net/snmp``` * `/net/snmp`
* ```/net/snmp6``` * `/net/snmp6`
So if nothing is given, no paths in config and in env vars, the plugin takes the default paths. So if nothing is given, no paths in config and in env vars, the plugin takes the default paths.
