Network Traffic
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
