Network: Interface Bytes

This statistic measures network interface activity in bytes/sec. Network interfaces are the logical network interfaces (see Network Configuration in Oracle ZFS Storage Appliance Administration Guide, Release OS8.7.x). The measured bytes by this statistic includes all network payload headers (Ethernet, IP, TCP, NFS/SMB/etc.)

Example

See Network: Device Bytes for an example of a similar statistic with similar breakdowns.

When to Check Interface Bytes

Network bytes can be used a rough measure of appliance load. This statistic can be used to see the rate of network bytes through different interfaces. To examine network devices that make up an interface, especially to identify if there are balancing problems with LACP aggregations, use the Network Device bytes statistic.
