ALR0536E The Total Port Data Rate of port port name in device device name was measured to be measured value MiB/s, which violated the defined critical-stress boundary value of boundary value MiB/s.
Explanation
Total Port Data Rate measures the average number of mebibytes per second transferred for storage system ports or switch ports. A threshold was defined on this metric, which causes the measured value to be compared to the defined boundaries for each set of performance statistics collected from the storage system.
This message indicates that a threshold boundary violation occurred. In this case, the specified port in the storage system or switch has a Total Port Data Rate that is greater than or equal to the critical-stress boundary that was defined for the related threshold.
Action
The threshold violation might indicate that the port is being overloaded with too high a workload. If this is the case, moving some of the port's workload to other less busy ports might resolve the problem.
However this threshold indication is only as good as its defined boundary values. If the specified boundary value is too low, IBM Spectrum Control might recognize many violations, even though there is really no underlying problem with the workload for the port. In this case, increase the boundary value in the threshold definition to reduce the number of unnecessary alerts.
