Network: Datalink Bytes

This statistic measures network datalink activity in bytes/sec. Network datalinks are logical entities constructed from network devices (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 Datalink 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 datalinks.
