Number of session state machine
transitions to transient state
I The number of session state machine
transitions to the transient state. A session
enters the transient state when:
— The current active connection dies.
— Task Management cold reset is in
progress.
— Session logout has occurred.
— Flow control has been enabled.
Number of session state machine
transitions to offline state
I The number of session state machine
transitions to the offline state.
Number of requests to enable
session flow control
I The number of requests from the network
interface driver to enable session flow control
for I/Os. This might be the result of excessive
I/Os through a session that impacts general
network performance.
Number of requests to disable
session flow control
I The number of requests from the network
interface driver to disable session flow control
for I/Os.
Number of async events "target
will drop all connections"
received
I The number of asynchronous requests from
the target to perform a session logout.
Number of SendTargets
command send failures
D/I/T The number of PDU send attempts that
failed. This could be the result of resource
allocation problems or target connectivity
issues.
Number of unexpected events
received in session online state
D The number of session state machine
unexpected events received while in the
online state. The unexpected events will be
ignored, and will not impact operations. If
this value is non-zero, an investigation into
the cause of the unexpected events should be
initiated.
Number of unexpected events
received in session transient
state
D The number of session state machine
unexpected events received while in the
transient state. The unexpected events will be
ignored, and will not impact operations. If this
value is non-zero, an investigation into the
cause of the unexpected events should be
initiated.
