The netif input plugin, gathers the information about the network traffic of the running system every certain interval of time and reports them.
The plugin supports the following configuration parameters:
Key | Description |
Interface | Specify the network interface to monitor. e.g. eth0 |
Interval_Sec | Polling interval (seconds). default: 1 |
Interval_NSec | Polling interval (nanosecond). default: 0 |
Verbose | If true, gather metrics precisely. default: false |
In order to monitor network traffic from your system, you can run the plugin from the command line or through the configuration file:

In your main configuration file append the following Input & Output sections:
[INPUT]Name netifTag netifInterval_Sec 1Interval_NSec 0Interface eth0[OUTPUT]Name stdoutMatch *
Note: Total interval (sec) = Interval_Sec + (Interval_Nsec / 1000000000).
e.g. 1.5s = 1s + 500000000ns
