Kernel Reader (Simple) Module Version 1.0

The Kernel Reader (Simple) module generates a warning alarm if the module finds any disk with an increasing wait queue while busy.

A warning alarm occurs when the disk is over 75% busy and the average queue length is over 10 with an increasing wait queue. The warning alarm is on until the disk is not over 70% busy and the average queue length is no longer than 8. Similarly, this module generates a warning alarm if 90% of swap space is in use. The alarm remains open until the swap space in use is less than 80% of the total swap space.

The following table provides default alarm thresholds for applicable Kernel Reader modules.
