Gauges are graphical and tabular presentation of performance and exception data. You can use the Display gauge function on the Gauges panel to view the gauge definition of a selected performance data-collection task.
Each selected metric is represented by one line in the gauge. The y-axis of the chart measures the metric value. The metric value ranges from 0 to the greatest value registered by the performance data for all of the selected metrics. Date and time are shown on the x-axis. For static performance gauges where the start and end date and time were specified during gauge creation, the x-axis displays the start date and time, the end date and time, and a number of date and time markers between them. For dynamic performance gauges (showing current data), the number of data points equal the number of sample intervals that were selected during gauge creation.
The exception count for the selected device is shown in a bar chart. For each day selected in the gauge definition, the chart displays one bar. The types of threshold exceptions that are shown in the subdivisions are device dependent. The list of threshold exceptions for each device is shown in the Thresholds Task section. Only enabled thresholds for which the threshold values were exceeded appear in this gauge.
The y-axis of the chart measures the number of threshold exceptions detected during the days specified during the creation of the gauge definition. The dates selected are shown on the x-axis. One marker is shown for every day selected when the gauge was created.
The tables contains the data used to create the gauge. The tables display the following types of information:
