The netif input plugin gathers network traffic information of the running system every certain interval of time, and reports them.
The Network I/O Metrics plugin creates metrics that are log-based, such as JSON payload. For Prometheus-based metrics, see the Node Exporter Metrics input plugin.
The plugin supports the following configuration parameters:
| Key | Description | Default |
|---|---|---|
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:
Note: Total interval (sec) = Interval_Sec + (Interval_Nsec / 1000000000).
e.g. 1.5s = 1s + 500000000ns
Interface

Interval_Sec
Polling interval (seconds).
1
Interval_NSec
Polling interval (nanosecond).
0
Verbose
If true, gather metrics precisely.
false
Test_At_Init
If true, testing if the network interface is valid at initialization.
