The netstat collector reads data from /proc/net/dev and outputs a handful node metrics. With the include_devices list you can specify which network interfaces should be measured. Optionally, you can define an interface_aliases mapping. For each canonical device (as listed in include_devices), you may provide an array of aliases that may be reported by the system. When an alias is detected, it is mapped to the canonical name, while the output tag stype-id always shows the actual system-reported name.

Both filtering mechanisms are supported:

• exclude_metrics: Excludes the specified metrics.
• only_metrics: If provided, only the listed metrics are collected. This takes precedence over exclude_metrics.

Absolute Metrics:

• net_bytes_in (unit: bytes)
• net_bytes_out (unit: bytes)
• net_pkts_in (unit: packets)
• net_pkts_out (unit: packets)

Derived Metrics:

• net_bytes_in_bw (unit: bytes/sec)
• net_bytes_out_bw (unit: bytes/sec)
• net_pkts_in_bw (unit: packets/sec)
• net_pkts_out_bw (unit: packets/sec)

The device name is added as tag stype=network,stype-id=<device>.
