ALR0606W The Port Receive Utilization Percentage of port port name in storage system storage system name was measured to be measured value%, which violated the warning-idle boundary value of boundary value%.
Explanation
Port Receive Utilization Percentage measures the approximate utilization percentage of the ports in monitored storage systems. This value represents the average percent of time that the ports were busy receiving data. 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 Port Receive Utilization Percentage value that is less than or equal to the warning-idle boundary, but greater than the critical-idle boundary that was defined for the related threshold.
Action
The threshold violation might indicate an unexpected drop in the workload for this port. This can happen if the application(s) using the port stopped working properly.
This type of threshold boundary should only be defined if the workload for the ports in a storage system are guaranteed to always remain at a certain minimum level. Otherwise IBM Spectrum Control might recognize many violations, even though there is really no underlying problem with the applications. In these situations, consider decreasing the boundary value in the threshold definition, or disabling the boundary check by leaving the boundary value blank.
