ALR0586W The Port to Local Node Send Queue Time of node node name in storage system storage system name was measured to be measured value ms/op, which violated the defined warning-idle boundary value of boundary value ms/op.
Explanation
Port to Local Node Send Queue Time measures the average number of milliseconds that each send operation to another node in the local storage system spent on the queue before being issued. 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 node in the storage system has a Port to Local Node Send Queue Time 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 node. This can happen if the application(s) using the node stopped working properly.
It makes little sense to enable an idle boundary for the queue time thresholds, because a zero or low queue time is the ideal and expected situation. It is recommended to disable the idle boundary checking by leaving the idle boundary values blank in the related threshold definition.
