Percent Utilization ‑ Line Chart

Percent Utilization data points are joined by straight lines. Each vertex of the resulting line graph corresponds to the Percent Utilization of the selected interface at the time of polling.

Percent Utilization - Step Chart

Instead of merely displaying data points, the Percent Utilization - Step Chart joins utilization measurement points on the chart with a straight line, and the Percent Utilization - Step Chart displays utilization levels as discrete steps. On the step chart, steps measurement points on the chart with a straight line.

Customization tips

Sample interval and time periods

  • Each sample interval is represented by a bar. Data within a selected sample interval is summarized automatically.
  • Some charts may not display due to large amounts of historical data or short sample intervals, and may decrease performance.

Display calculated lines

Add lines to the chart representing important values so that you know at first sight when the values are getting near to an important level.

Click Edit, select a line, and submit your changes. The lines will be displayed in the chart.

Show trend

Select Show a Trend Line to display a line representing potential future results. This line is extrapolated from collected historical data, and is thus only an approximate prediction of future data.

Trend lines on charts are intended as approximate predictions of future data. This is because there are many reasons that can affect the performance of devices on your network.

Percentile 95th

Select Show the 95th Percentile line to include a line marking the 95th percentile for the data collected over the indicated time period.
