Resource Model Reference
This indication is sent when the network interface card is overworked.
Bytes per second through the network card is too high and the outbound queue
length is getting too large.
The indication has the following attributes:
- OutputQueueLength
- The number of requests queued up to be sent out the network interface card
- NICBPS
- The bytes per second transferred through the network interface card
- CurrentBandWidth
- The bandwidth of the network interface card
- NetworkInterface
- The identity of network interface card being examined (Key attribute)
The indication is generated when the following threshold is exceeded:
| Threshold
| Description
| Default
|
| High Output Queue Length Modifier (HighOutputQueueLengthMod)
|
The network card has an output queue that is used to queue network
requests. This threshold is a modifier that can be adjusted by the
administrator to adjust the threshold for the output queue length for the
network interface. This threshold is calculated using the total number
of network interface cards in the system plus this value.

| 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. Because there will be an internal dynamic calculation, the
threshold value is a percentile that indicates what percentage of the
bandwidth is considered too high. For example: 830 KBPS is
considered high for 10 MB ethernet networks. This value is about 8
percent.
