Trap PDU

You can change the high and low threshold values while the subagent is running by

setting the values of zhrmThrRAMHighValue and zhrmThrRAMLowValue (for RAM

storage areas) and zhrmThrDiskHighValue and zhrmDiskLowValue (for disks) in the

zhrmThreshold group. If a threshold is changed such that a trap would be generated at

the current activity level, a trap is not generated until the activity level changes.
