DescriptionAttribute NameSection
Network utilization, as a percentage, is
computed by dividing the observed network
use in megabits per second (Mb/s) by the
estimated network capacity for the system.
For more information see “Units and
terminology” (page 211).

Avg Network I/O (%)
The amount of data transferred over the
network, measured in Mb/s.
For more information see “Units and
terminology” (page 211).

Avg Network I/O (Mb/s)
The number of data and information packets
transferred per second.
This metric is only collected from physical Linux
and Windows systems.

Avg Network I/O (packets/s)
The system's network I/O capacity as defined
by the user. If a user value was not explicitly
entered for the system, then the maximum
observed capacity or 100 Mb/s, whichever is
higher, is used to estimate capacity. See Net
HWM (Mb/s) below.
Net I/O Cap (Mb/s)Network Capacity
The observed high water mark for network
utilization. This is the peak network utilization
over the history of the server, not just the
selected interval.
Net HWM (Mb/s)
The headroom percentage indicates how much
the demand for the network I/O could grow
before violating the system's network I/O
utilization limits.
This metric is capped at 3100% to avoid
dividing by zero or other small numbers.

NOTE: Peak, 15-minute sustained, 90th percentile, and average values are available as separate
attributes. See Table 13 (page 115).
