Threshold Overview
Cluster resources use thresholds to trigger HP Systems Insight Manager (HP SIM) events. The Disk resource sets thresholds for disk capacity, and the CPU resource sets thresholds for CPU utilization.
Disk Capacity ThresholdsThe Disk resource collects disk capacity data. To access the Cluster Monitor - Node Resource Settings page where the thresholds are set, select Options Cluster Monitor Node Resource Settings. The threshold values you enter in the Settings for the Selected Resource section define the Normal, Minor, and Major ranges for disk utilization on monitored nodes. For each disk, there are four thresholds in pairs. The Minor and Major thresholds are each associated with a corresponding reset threshold. Utilization enters the Major range when it equals or exceeds the Major threshold value and remains in the Major range until it falls to or below the Major reset value. The Minor and Major reset thresholds behave similarly. You can specify different thresholds for each disk in each node of a cluster. Refer to Cluster Monitor - Configuring Node Resource Settings for more information on setting disk thresholds. CPU Utilization ThresholdsThe CPU resource collects utilization data for the CPUs in a particular. To access the Cluster Monitor - Node Resource Settings page where the thresholds are set, select Options Cluster Monitor Node Resource Settings. The threshold values you enter in the Settings for the Selected Resource section define the Normal, Minor, and Major ranges for CPU utilization on the selected node. For each CPU, there are four thresholds in pairs. The Minor and Major thresholds are each associated with a corresponding reset threshold. Utilization enters the Major range when it equals or exceeds the Major threshold value and remains in the Major range until it falls to or below the Major reset value. The Minor and Major reset thresholds behave similarly. You can specify different thresholds for each CPU in each node of a cluster. Refer to Cluster Monitor - Configuring Cluster Resource Settings for more information on CPU thresholds.
