ALR0553W The Total Port Frame Rate of port port name in switch switch name was measured to be measured value frm/s, which violated the defined warning-stress boundary value of boundary value frm/s.
Explanation
Total Port Frame Rate measures the average number of frames transferred per second for 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 has a Total Port Frame Rate value that is greater than or equal to the warning-stress boundary, but less than 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.
