Multiple Thresholds

For this metric category, you can set different warning and critical threshold values for each Interface Name object.

If warning or critical threshold values are currently set for any Interface Name object, you can view those thresholds from the All Metrics page for this metric.

To specify or change warning or critical threshold values for each Interface Name object, use the Modify Thresholds page.
