Redirector Overloaded Affecting Segment

This indication is sent when the redirector, or workstation service, is being overloaded and it is generating a bottleneck on the network segment. The current commands and bytes per second on the redirector are exceeded. This usually causes the percentage utilization of the network segment to be exceeded.

The indication has the following attributes:

CurrentCommands: The current commands that are queued for service on the redirector
RedirectorBPS: The number of bytes per second transferring through the redirector
CurrentBandWidth: The bandwidth of the network interface card
PercentNetworkUtil: The percentage of network utilization on the segment
NetworkSegment: The network segment being analyzed (Key attribute)

The indication is generated when the following thresholds are exceeded:

Threshold	Description	Default
High Current Commands Modifier (HighCurrCmdsMod)	This threshold counts the requests to the redirector that are currently queued for service. If this number is much larger than the number of network adapter cards installed in the computer, the networks, servers, or both being accessed have a serious bottleneck. This value is used in conjunction with the number of network cards installed on the system. The final threshold value is calculated by multiplying the number of network cards in the system by this threshold.	10
High Percent Broadcast (HighPercentBroadcast)	This threshold must not be exceeded.	90
High Percent Bytes Per Second (HighPercentBytesSec)	To test for a high amount of bytes per second, a dynamic threshold value needs to be created based on the current bandwidth of the network interface card. When the bytes per second through the redirector are greater than the number of high bytes per second, this indication is sent. This value is calculated by multiplying the current bandwidth with the High Percentage Bytes per Second threshold, and dividing the result by 100.	9
High Percent Utilization (HighPercentUtilization)	This threshold determines at what point the network utilization of the internal segment is too high.	40

The following table shows the default settings for this indication:
