Table 18 Attributes available for use in analysis queries: Network Tab (continued)

Description

Attribute Name

Section

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.

Network I/O Headroom

NOTE:

Peak, 15-minute sustained, 90th percentile, and average values are available as separate

attributes. See

Total data being transferred, measured in
MB/s.

Disk I/O Utilization (MB/s)

15–Min Disk I/O (MB/s)

90%ile Disk I/O (MB/s)

Avg Disk I/O (MB/s)

The number of data disk transfers per second,
measured in Input/Output Operations per
Second (IOPS). Each disk block that is read or
written counts as an I/O operation.

This metric is only collected from physical Linux
and Windows systems.
