Chart types and configuration options for each chart type.

VMware Aria Operations for Applications (formerly known as Tanzu Observability by Wavefront) provides charts viewing and examining your data. You can interact directly with charts in real time – zoom in, zoom out, change the time window, and so on.

Users with dashboard permission can customize many aspects of the chart and save their changes. This page is a detailed reference to the tabs in the different chart types. We repeat tab reference for each chart type.

Data Tab (All Charts)

For each chart (with the exception of a Markdown and Logs Table chart) you specify one or more queries.

When you click Data, you can:

  • View queries for the chart and add lines.
  • Use Chart Builder or Query Editor.
  • Clone, delete, or hide one or more lines.
  • Create an alert based on a chart.

Line Plot Chart

A screenshot of the line plot chart.

Line plots are well suited both for single time series and multiple time series. You can customize many aspects of your line plots.

A line plot represents interpolated point buckets. The X axis represents the amount of time in your time window and the Y axis represents the value associated with the data based on that time.

Missing data is represented by a dashed line. The dashed line only gives a visual representation of the data stream; it does not represent values of the missing data. If you hover over the chart, you won’t see values where the gap threshold has been applied. Use the Format > Gap Threshold property to set the amount of time before gaps of missing data display as dashed lines.

Format Tab

OptionDescription
Summarization The summarization option is used by the query engine to aggregate raw data points into displayable values.

Consider the following example. The horizontal scale for your chart is "240 point buckets across, 1 bucket – 30 sec (est)". If you choose Median, the query engine aggregates the raw data values reported in each 30-second interval and displays the median value as the data point for that bucket.

Display Source Events If checked, displays events that were generated by alerts associated with any source displayed on the chart. You can also use events() queries to Display events in charts.
Gap Threshold Controls when data is considered missing when there are gaps in the reporting of the data. The gap threshold is expressed in seconds and defaults to 60 seconds.
Show Single Line Gradient Allows you to turn off or turn on the single line color gradient when you're looking at a line chart and you have only a single line.
Decimal Precision How many digits to show after the decimal point. Defaults to 3.

Axis Tab

The Axis tab lets you customize the Y axis. The customization is the same for both Line Plot and Point Plot. See Use a Logarithmic Y Axis for Skewed Data and Use IEC/Binary Prefixes in Y Axes and Legends for instructions.

OptionDescription
Y-Axis Scale of the Y-axis: linear or logarithmic. Default is linear. In most cases, linear is sufficient as long as there is not a large difference in measurement between the reported data points. If there's a large difference in measurement scale, use the logarithmic scale. By default, the logarithmic scale is set to the power of 10. You can configure the scale in the adjacent text field.
Min/Max Minimum and maximum value on the Y-axis. If you are using a double Y-axis, you can specify min/max values for each Y-axis (By default, set to auto).
Unit Unit of measurement to assign to the label that appears along the Y-axis. This unit does not change the unit of measurement. If you are using a double Y-axis, you can specify a unit for each Y-axis.

Supported units are:

  • Time - Ranges from yoctoseconds (ys) to years (yr)
  • IEC/Binary - data size in IEC/Binary units. Ranges from B (bytes) to YiB
  • SI - data rate in SI units. Ranges from bps (bits/s) to Ybps. For details on SI units, see Wikipedia or a similar source.
  • If you select IEC/Binary Unit Prefixes, then the chart uses 1024 instead of 1000 as the step to the next unit prefix.

For details on unit prefixes and dynamic units, see Units in Chart Axes and Legends.

Legend Tab

Controls the legend displayed for the chart by default. The options are the same for line plot and point plot charts.

When you look at the chart, you can also control the legend with these keyboard shortcuts:

  • Shift+P – Pin the legend.
  • Shift – Show detailed units in the legend.
OptionDescription
Options You can select all or none of the Legend options.
  • Fixed Legend -- Even if you don't select this option, you can use Shift+P with the mouse cursor in the chart to add a fixed legend.
  • Non-summarized Stats -- Whether to report summarized or raw values for all metric values and statistics. When this setting is disabled, the legend reports summarized values according to the chosen Summarization option.
  • Disable Legend on Hover -- Select to disable the legend on hover.
Position Position of the fixed legend.
Display The values and statistics to display in the legend: current, mean, median, sum, min, max, and count.

Gap Threshold Controls when data is considered missing when there are gaps in the reporting of the data. The gap threshold is expressed in seconds and defaults to 60 seconds. Data considered missing based on the threshold are shown as dotted lines.
Stack Type The following stack types are supported.
  • Zero - Displays the chart from 0 up to the sum of all points at that time interval. Default.
  • Normalize to 0-1 - Results in a similar shape to Zero except that the values are normalized so that they fill the range between 0 and 1 with the peak of the chart always a solid line drawn at magnitude 1.
  • Minimize Weighted Change - Plots the area while attempting to minimize the weighted change in the slope of the lines. Both this and the Center the Stream option tend to result in similar shapes in which the chart does not show a solid area beginning at 0.
  • Center the Stream - Represents the collective magnitude of the queries displayed on the chart with the band narrowing or widening as the metrics fluctuate over time.
  • Stacked Columns - Shows the result as a set of stacked columns, which resemble a bar chart.
Decimal Precision How many digits to show after the decimal point. Defaults to 3.

Markdown Chart

A Markdown chart allows you to provide in-depth text descriptions of a dashboard and individual charts using Markdown. We support CommonMark

In addition to Markdown formatted text, you can use links, images hosted at a location of your choice, and dashboard variables. You can refer to the value of a dashboard variable with the query variable syntax ${var_name} and the label of the variable using %{var_name}. Using a label instead of the variable value could be useful for list variables that might show the dropdown labels such as: Any, 1 Year, 3 Years which could map to opaque values such as -1, 1, 3.

You can pass a time window as a parameter in markdown. For example, when you create a dynamic link in a markdown chart, from the time selector you can pick a specific time window. When you click the link on the markdown chart, you will see the chart within the current time range that you’ve selected.

When you add a markdown chart with a dashboard dynamic link to an existing dashboard, for example, [[dashboardURLWithCurrentTimeRange url=/tracing/service/details title=MyChart]], clicking the link on the markdown chart, will open a dashboard within the time range that is specified in the parent dashboard, i.e. the dashboard to which you’ve added the markdown chart.

Single Stat Chart

single stat

By default, a single stat chart plots a single series on a chart and displays a summarized value for that series in large font on the chart. The font size and placement of the displayed value can be unique for each chart. A common use case is displaying instantaneous values of critical metrics on an overhead display.

Format Tab

OptionDescription
Summarization The summarization option is used by the query engine to aggregate raw data points into displayable values.

Consider the following example. The horizontal scale for your chart is "240 point buckets across, 1 bucket – 30 sec (est)". If you choose Median, the query engine aggregates the raw data values reported in each 30-second interval and displays the median value as the data point for that bucket.

Display Value Allows you to show the value or the query label. Initially, labels are consecutive starting at A.
Display Subtitle Optional subtitle below the value (or label).
Decimal Precision How many digits to show after the decimal point. Defaults to 3.
Horizontal Position Allows you to set the alignment to Left, Middle, or Right
Font Size Relative font size from 75% to 200%.
Text Color Color of the value or label text displayed in the chart.
Prefix Allows you to prefix the value (or label) with a text string. For example, you could show the source or environment.
Postfix Allows you to append text to the value (or label). For example, you could show the source or environment.
Value/Text Mapping Allows you show the text lower, middle, or upper instead of the value itself.
Gap Threshold Controls when data is considered missing when there are gaps in the reporting of the data. The gap threshold is expressed in seconds and defaults to 60 seconds.
Display Raw Value Select this check box if you've selected a unit and you want to display, for example, 10k instead of 10000. Selected by default.
Comma Delimited Select this check box if you've selected a unit and you want to display, for example, 1,000 instead of 1000. Works only for values higher than or equal to 1000 and is selected by default.

Node Map Chart

A screenshot of the node map chart

A node map chart shows colored 3-D cubes ordered from highest to lowest. Node maps show data based on source values.

  • By default, the node map displays the highest value on the top left to catch the user’s eye.
  • When a user clicks a node, a small popup of the corresponding metric for that source results. You might have to modify the query to ensure that the query returns a source. In some cases, it’s necessary to use aliasSource() to get the desired results.
  • Use color mapping to determine colors for higher values. The node map uses shading to show transitions. In the example above, values below 0.1 are shown in yellow, values below 0.2 are shown as green, values between 0.2 and 0.4 are shown as a shade of brown.
  • Set the group and the metric to display in the top right or on the Node Map Defaults tab in the chart editor.
  • Set the maximum number of node groups to display on the Node Map Defaults tab. The highest number is 35.
  • Specify a drilldown link to direct users to a different dashboard if they click on the dashboard.

When you refresh a node map page, a short animation folds out the chart content.

Color Mapping Tab

The color mapping tab lets you define which set of values maps to which colors. In the example above, values less than 0.3 are green, values less than 0.8 are yellow. All other values are red. See How Do I Set Up Color Mapping for details.

Node Map Defaults Tab

OptionDescription
Max Node Group Count Specifies the maximum number of node groups to display. You can select 10, 15, 20, 25, 30, or 35 node groups to display on the chart. The default is 10. In the example above, the maximum number of node groups is set to 15 and 11 groups are displayed.
Default Group by Specifies grouping.
Default Metric Metric you're interested in. Each cube in the node map displays one node and you can, for example, create a set of queries to monitor for CPU, memory, and bandwidth issues.
Node Title Tag Lets you set the title of the popup line chart to the source (default) or one of the point tags.
Default Node Color Lets you pick the color of nodes with values that are below any of the thresholds.

Drilldown Link Tab

Histogram Chart

A screenshot of the histogram chart

Histogram charts have two main uses:

  • Visualize actual histograms. Our histograms let you compute, store, and use distributions of metrics rather than single metrics. Histograms are useful for high-velocity metrics about your applications and infrastructure – particularly those gathered across many distributed sources.
  • Display a histogram visualization of a time series. That makes it possible, for example, to easily see query results above a certain percentile.

You can zoom in to the histogram as needed by selecting a region.

The histogram chart shows the aggregate view of the entire window. For both histogram data and time series data, you can visualize the amount of data in a certain percentile, specify color gradient and axis information, and, most importantly, get details about your histogram data by looking at hover text on each bar.

From the chart’s edit menu, you can go to the corresponding trace (if any).

Go to Traces menu

Data Tab

In contrast to other chart types, you must use the query editor to enter histogram information.

One easy way to show a histogram is from the Histogram browser.

  1. Select Browse > Histograms
  2. Drill down to the metric you’re interested in and double-click it to open it in a chart.

You must make sure you’re looking at a metric – it doesn’t make sense to select a folder.

Format Tab

OptionDescription
Color Gradient Lets you select a start and end color for the histogram gradient.
Percentile Markers Display predefined percentile makers as numbers on the chart.
Threshold A threshold marker for the data represented by the chart. Can be either a constant value or a variable that is defined by a query.

Axis Tab

The Axis tab lets you change the Y axis, and both the X axis dimensions and units.

OptionDescription
Y-Axis Scale of the Y-axis: linear or logarithmic. Default is linear. In most cases, linear is sufficient as long as there is not a large difference in measurement between the reported data points. If there's a large difference in measurement scale, use the logarithmic scale. By default, the logarithmic scale is set to the power of 10. You can configure the scale in the adjacent text field.
Min/Max Y axis minimum and maximum value. Use these two options to change the height of your histogram bars.
X-Axis Min / X-Axis Max Allows you to specify the minimum and maximum on the X axis, in effect, filtering out some of the left-most and right-most bars that the chart displays.
Unit Unit of measurement to assign to the label that appears along the X-axis. This unit does not change the unit of measurement. This unit also does not affect the Y axis.

Supported units are:

  • Time - Ranges from yoctoseconds (ys) to years (yr)
  • IEC/Binary - data size in IEC/Binary units. Ranges from B (bytes) to YiB
  • SI - data rate in SI units. Ranges from bps (bits/s) to Ybps. For details on SI units, see Wikipedia or a similar source.
  • If you select IEC/Binary Unit Prefixes, then the chart uses 1024 instead of 1000 as the step to the next unit prefix.

For details on unit prefixes and dynamic units, see Units in Chart Axes and Legends.

Heat Map Chart

A screenshot of the heat map chart.

Heat map charts add another dimension to the information about histograms that you see in a histogram chart.

  • The X axis shows time (same as a line plot)
  • The Y axis shows distribution values (just like the X axis in histogram charts). This is what you’re recording, for example, latency.
  • The color saturation shows the amount of data for the selected time frame.

Data Tab

In most cases, it makes sense to do an hs() query in the Query Editor.

One easy way to show which histograms are on your cluster is from the Histogram browser.

  1. Select Browse > Histograms
  2. Drill down to the metric you’re interested in and double-click it to open it in a chart. You must make sure you’re looking at a metric – it doesn’t make sense to select a folder.

Format Tab

OptionDescription
Display Source Events When checked, shows events associated with any source related to the data in the X axis.
Color Base color for the heat map. The saturation of the color indicates the count for the selected field. Hover over any field to see a vertical histogram as a legend that you can pin with Shift+P. The histogram highlights the vertical line that corresponds to the grid cell you've selected.legend for a single heatmap field
Threshold A threshold marker for the data represented by the chart. Can be either a constant value or a variable that is defined by a query.

Axis Tab

The Axis tab lets you change the Y axis, and both the X axis and Y axis dimensions and units.

OptionDescription
Y-Axis Min/Max Y axis minimum and maximum value.
Y Axis Unit Unit of measurement to assign to the label that appears along the Y-axis. For example, select Dynamic Units and then change to microseconds. This option does not change the unit of measurement.

Supported units are:

  • Time - Ranges from yoctoseconds (ys) to years (yr)
  • IEC/Binary - data size in IEC/Binary units. Ranges from B (bytes) to YiB
  • SI - data rate in SI units. Ranges from bps (bits/s) to Ybps. For details on SI units, see Wikipedia or a similar source.
  • If you select IEC/Binary Unit Prefixes, then the chart uses 1024 instead of 1000 as the step to the next unit prefix.

For details on unit prefixes and dynamic units, see Units in Chart Axes and Legends.

Y-Axis Bucket Count/X Axis Bucket Count The size of each bucket. For the X axis, the bucket count is also shown right below the chart itself.

Gauge Chart

A screenshot of the gauge chart

A gauge chart displays a single value, in a default color. You can optionally add color mapping. If you do, the which displays in an outer ring. By default, color mapping uses 0-100, but you can define a minimum and maximum.

Format Tab

OptionDescription
Summarization The summarization option is used by the query engine to aggregate raw data points into displayable values.

Consider the following example. The horizontal scale for your chart is "240 point buckets across, 1 bucket – 30 sec (est)". If you choose Median, the query engine aggregates the raw data values reported in each 30-second interval and displays the median value as the data point for that bucket.

Decimal Precision How many digits to show after the decimal point. Defaults to 3.
Prefix Allows you to prefix the value (or label) with a text string. For example, you could show the source or environment. The font of the prefix is smaller than the display font.
Postfix Allows you to append text to the value (or label). For example, you could add the unit of measurement.
Default Color Color that's used for the value and the gauge ring when no color mapping is defined. Default is blue. See the chart on the left in the image above.
Color Mapping Adds an outer ring and splits that outer ring into color zones that show possible values of the gauge. See the chart on the right in the image above.
By default, the gauge displays color information for 0-100 even if you define a mapping for a different range. Specify Min and Max to change what the outer ring shows. See Why Doesn't the Outer Ring of My Gauge Change?
Min Minimum value to use for the outer ring of the gauge. If no color mapping is defined, the gauge ranges from Min to Max. With color mapping defined, the outer ring is also affected.
Max Maximum value to use for the outer ring of the gauge. If no color mapping is defined, the gauge ranges from Min to Max. With color mapping defined, the outer ring is also affected.
Display Raw Value Select this check box if you've selected a unit and you want to display, for example, 10k instead of 10000. Selected by default.

Drilldown Link Tab

The Drilldown Link tab allows you to specify a target dashboard that displays when a user clicks on the gauge chart. You can optionally customize the target dashboard. For example, you can specify a constant us-west-2 to be used as a variable.

Pie and Donut Chart

Pie and donut charts showing the same data.

A pie chart shows the relative size of your data as pie slices. You can show either a pie chart or a donut chart. You can customize the width of the donut ring (by percentage) and, the percentile shown for the number, and more.

The collage above shows both a pie chart and a donut chart for the same data.

Format Tab

OptionDescription
Type Select a pie chart or donut chart. If you pick a donut chart, you can set a ratio to make the ring thicker or thinner.
Summarization The summarization option is used by the query engine to aggregate raw data points into displayable values.

Consider the following example. The horizontal scale for your chart is "240 point buckets across, 1 bucket – 30 sec (est)". If you choose Median, the query engine aggregates the raw data values reported in each 30-second interval and displays the median value as the data point for that bucket.

Display Value Select a value you want to display on the chart. You see the values as a percentage.

For example, if the query you use gets the CPU usage of all the applications, and you select Sum, you can see how the CPU usage of an application compares to all the other applications for a given time window.

  • Current: Display the current value for the Summarization option you selected as a percentage.
  • Mean: Display the mean of the raw data values as a percentage.
