How is the Smarts IP HighErrorRate event calculated?

How do you validate the data received in a Smarts IP HighErrorRate event?

What formula is used to calculate a Smarts IP HighErrorRate event?

How is the HighErrorRate event calculated?



 

To get the data from the Smarts IP topology that generated a HighErrorRate event, run the following dmctl command against the port while the HighErrorRate event is active:

dmctl -s <domain name> get Port_Performance_dot3_Ethernet::I-Port_Performance_dot3_Ethernet-<Port name>

Direct the output to a file.

Use the following equation and plug in the values in the output file:

( InputPacketErrorRate > MinimumErrorRate ) && ( InputPacketErrorPct > ErrorThreshold )

For Example:

ErrorThreshold = 10

InputPacketErrorPct = 108393.9609

InputPacketErrorRate = 13981.0137

MinimumErrorRate = 166.6667

Now plug in the numbers into the equation:

( 13981.0137 > 166.6667 ) && ( 108393.0137 > 10)

And the HighErrorRate event is valid.
