Status

The Status block is used for reporting adapter status information. More...

The Status block is used for reporting adapter status information.

The Status block is an implementation of a universal control (see Universal Control).

Data types

The list of supported datatypes is as follows:

entity_type_cstring

ASCII character.

entity_type_sequence

Sequence of potentially heterogeneous entities.

Conceptually similar to C struct.

entity_type_int

A 32 bit integer.

entity_type_float

An ieee754 binary 32 bit float.

Status

Status

Adapter status block parameters report status information

CPU Utilization

A measure of how busy the processor is

Temperature

The adapter's temperature

Power Source

The adapter's power source
