HP Network Direr Software Products manual Event System Configuration

Event System Configuration 359

Threshold Value: The absolute value of the high threshold can be set directly in the High stress threshold value.

Changes made to the High stress threshold value will be reflected automatically in the sensitivity slider and the Warning stress threshold value.

If the value you enter in the High stress threshold value is larger than the current range of the Sensitivity slider then the range of the Sensitivity slider will be adjusted so that its least sensitive setting matches the entered High stress threshold value.

The range of the Sensitivity slider is recalculated to a suitable range every time you launch the Threshold Settings dialog box for an event.

For example, the default range for the Network Instability monitor is a value from 10 minutes to 1440 minutes (1 day). If you enter a value of 2880 minutes (2 days) in the High stress threshold value and apply it to This device then the next time you launch the Threshold Settings dialog box for the same device the range of the Sensitivity slider will be from 10 minutes to 2880 minutes. If you subsequently change the High stress threshold value to 120 minutes and apply it to This device then the next time you launch the Threshold Settings dialog box for the same device the range of the Sensitivity slider will revert back to the default range of 10 minutes to 1440 minutes.

Use Suggested Settings: For most monitor types, 3Com Network Director can suggest threshold values for you to use based on the monitor type. and on the events that have been previously generated by the monitor. To view, and optionally apply, these suggested values click Use Suggested Settings.

3Com Network Director cannot suggest threshold values for WAN link monitors.

Every monitor may have a different threshold for each item that it monitors. This allows you, for example, to set different utilization thresholds for a link to a server that is normally highly utilized and a backup link that is normally never utilized.

When you change a threshold for a monitor, you can select which items, as appropriate, to change the threshold for:
