Server Overloaded Affecting Segment

This indication is sent when there is a high work item shortage and a high bytes per second through the server service. The server for a segment is overloaded due to the high amount of data being requested from the server.

The indication has the following attributes:

WorkItemShortages: The number of times that work items cannot be allocated to service incoming requests to the server (Key attribute)
ServerBPS: The bytes per second being transferred through the server
CurrentBandWidth: The bandwidth of the network interface card
PercentNetworkUtil: The percentage value of network utilization on the segment
NetworkSegment: The identity of the network segment being analyzed (Key attribute)

The indication is generated when the following thresholds are exceeded:

Threshold	Description	Default
High Percent Broadcast (HighPercentBroadcast)	This threshold must not be exceeded.	90
High Percent Bytes Per Second (HighPercentBytesSec)	The bytes per second through the server are greater than the number of high bytes per second. This value is calculated by multiplying the current bandwidth with this 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
High Work Item Shortages (HighWorkItemShortages)	This occurs when no work item is available, or no work item can be allocated to service the incoming request. A work item is used when the server service receives a request. HighWorkItemShortages indicates that the initial work items or maximum work items parameters may need tuning.	10

The following table shows the default settings for this indication:
