AUDIT AN System Messages
AN-1003
Message AUDIT, <timestamp>, [AN-1003], WARNING, FABRIC, <event-initiator-details>,
<event-location>, , Latency bottleneck on port <slot number>/<port number within
slot number>. <percentage of seconds affected by latency bottlenecking> pct. of
<observation period over which the percentage of affected seconds is reported>
secs. affected. Avg. time b/w transmits <observed average time between frames
during affected seconds> us. Avg. slowdown <observed throughput drop factor during
affected seconds>.
Probable Cause For an F_Port, it indicates that the attached device is slow in responding to frames going out of this
port. This latency may be inherent in the device or due to heavy workload on the device. For an
E_Port, it indicates a downstream primary bottleneck.
Recommended
Action
If the port is an F_Port, examine the connected device for the source of the latency. If the port is a
long-distance E_Port, ensure that there are enough buffer credits to service the link distance.
Severity WARNING
AN-1004
Message AUDIT, <timestamp>, [AN-1004], WARNING, FABRIC, <event-initiator-details>,
<event-location>, , Slot <slot number>, port <port number within slot number> is a
congestion bottleneck. <percentage of seconds affected by congestion
bottlenecking> percent of last <observation period over which the percentage of
affected seconds is reported> seconds were affected by this condition.
Probable Cause Indicates that the volume of outgoing traffic at this port is too high for the capacity of the link.
Recommended
Action
Add more capacity on the path, using trunk links if possible.
Severity WARNING
AN-1005
Message AUDIT, <timestamp>, [AN-1005], INFO, FABRIC, <event-initiator-details>,
<event-location>, , Slot <slot number>, port <port number within slot number> has
<bottleneck type> bottleneck cleared.
Probable Cause Indicates that the bottleneck was cleared on the port.
Recommended
Action
No action is required.
