Chart dashlet

The Chart dashlet visualizes collected Measures. Various types of charts are available. You can find their descriptions below. See FAQ - Measures and Charting for more information about charts and measures.

Add series

To add a series to the chart:

  1. Right click the chart, and select Add Series from the context menu, or click Add Series in an empty chart.
  2. In the the Measure Picker dialog box, select the measure.
  3. If needed, configure slitting settings.

Configure series

To configure the chart series, right click the Chart dashlet and select Configure Series, or click the Series tab in the Dashlet Properties dialog box.

You can override the default chart-specific settings of each series with the following settings:

Setting Description
Color Set the color for the series representation in chart.
Scale Define a scale from 10-10 to 1010.
Aggregation Define the measurements aggregation.
Unit Defines the measurements units

Chart types

The following chart types are available:

Line chart

  • Represents any kind of Measures.
  • Similar to an Area chart but supports a higher number of Measures.

Step Chart

  • Renders its values with discrete steps.
  • Useful to display count Measures (threads).
  • Unlike Line charts, the intervals are not connected if data is unavailable for successive intervals.

Percentile chart

  • Plots percentiles from 0 to 100 for a time frame.
  • Chart time frame is one hour, regardless of configured time frame (based on one-hour percentile aggregation).
  • If the chart has many Measures, use a logarithmic y-axis to increase readability:
    1. Right-click the dashlet, and select Dashlet Properties from the context menu.
    2. In the Dashlet Properties dialog box, click the Axis tab.
    3. In the Y-Axis Properties pane, select the Logarithmic Y-Axis check box.

Area chart

  • To plot an area, you must have at least two data points per Measure in the configured time frame.
  • Multiple Measures are plotted in separate layers, therefore the chart cannot process numerous Measures.

Stacked area chart

  • Values are stacked for each time stamp.
  • To plot an area, you must have at least two data points per Measure for the configured time frame.

Clustered bar chart

  • Measures are represented by individual bars for each aggregated time stamp.
  • Increase the chart resolution to support numerous Measures.

Stacked percentage bar chart

Configure all Measures to use the same unit and aggregation.

Stacked bar chart

  • Measures are stacked for each aggregated time stamp, depending on the chart resolution.
  • Configure all Measures to use the same unit and aggregation so they are comparable.

Pie chart

  • The value shown depends on aggregation and the time frame.
  • See the Meter chart for more information about aggregation.

Pie chart 3D

  • The value shown depends on aggregation and the time frame.
  • See the Meter chart for more information about aggregation.

Meter chart

  • Shows the aggregated value of a Measure for the time frame.
  • The following explains the value calculation which depends on the aggregation:
    • Avg: Average value of available measurements within time frame.
    • Max: Maximum value within time frame.
    • Min: Minimum value within time frame.
    • Sum: Sum value of available measurements within time frame.
    • Count: Amount of measurements within time frame.
  • Resolution affects the displayed value.
  • Set a fixed axis lower and upper bound to disable the auto calculation of the y-axis.

Traffic light chart

  • Charts the threshold violation of a Measure.
  • Represents the most severe threshold violation within a time frame.
  • Threshold violation state is calculated against the configured aggregation.
  • Resolution effects how the threshold state is displayed.
  • You must define a proper threshold for the displayed Measure.
  • To analyze why a threshold is violated, hover over the chart to see the tooltip, or switch to a Line chart.

Chart splitting modes

By default all measures that are added to a chart are drawn as separate series within a single chart, except for the meter chart which is split by series by default and cannot be displayed without a splitting mode. To show different splittings in different charts, chart splitting settings have to be adjusted under Dashlet Properties > Split Chart.

The available splitting options are:

  • Agent Name
  • Agent Host
  • Agent Instance
  • Agent Group
  • Series
  • Measure
  • Application
  • Custom

Depending on the measure there might not be all options available. In order to avoid a massive amount of separate charts being shown, there is a configurable limit at which point all charts are drawn in a single chart even though chart splitting is enabled.

If a split mode is different from the splitting of the added measure is applied, the splitting is not replaced by the chosen split mode, but rather the split mode is added to the measure splitting. For example, adding a measure that is split by application to a chart and then choosing agent name as chart splitting mode results in different charts for each combination of agent name and application that values exist for.
