ciscoHealthMonitorHealthNotifyHighThreshold
cisco Health Monitor Health Notify High Threshold
1.3.6.1.4.1.9.9.243.1.1.1.4
Specifies the health level at which a ciscoHealthMonitorHealthLevel notification will be generated for the specified subsystem and entity. A notification will only be generated if the health level had previously reached the low threshold level prior to reaching this high threshold level. Health levels oscillating within the high and the low threshold levels do not generate notifications. A health level going from low threshold (or below) to high threshold (or above) represents a return to normal health for the specified subsystem. Set your optimal health level to this threshold.
