Panels are the building blocks used to create a dashboard. Each panel displays analytics for a specific query. The type of panel you choose to display your data depends on the type of query you want to run.
Time Series Panel
Time series panels provide information on a series of data points ordered in time. Typically, a time series is a sequence taken at successive equally spaced points in time. Examples of time series are CPU and Memory over time.
In a time series, time is often the independent variable and the goal is usually to make a forecast for the future. Time series are frequently plotted with area or line charts.
These are best used for looking at statistics taken over time. Things like CPU, Memory, and disk usage statistics fall into this category.
Time series panels accept aggregate fields with epoch values (milliseconds since 1970).
Available chart types:
What is the difference between a categorical and time series panel?
The categorical panel type contains charts that graph data across categories. This includes:
- Bar charts over categories
- Column charts over categories
- Pie Charts
- Tables over categories
- Bubble Charts
- Scatter Charts
The time series panel type is designed to graph data over time. Time series panels accept aggregate fields with epoch values (milliseconds since 1970). You can use the timeslice operator to provide a time series.
The types of charts you’ll find in the time series panel include:
Categorical panels provide information on the number of occurrences (frequency) of distinct values. Categorical frequencies are typically shown in pie, table, and column charts.
These are best used to understand the distribution of data by categories. For example, understanding the number of CPUs used by machine type, or the number of requests handled by a pod.
Available chart types:
The following image shows an example of Scatter and Bubble charts.
Single Value Panel
Single Value Panels are great at providing high level overviews. They look great on executive dashboards and can provide at-a-glance information to help decide where to inspect and troubleshoot further.
Only single value charts are supported.
Honeycombs are great at helping you find areas of significant activity amongst a set of entities, like hotspots in a cluster. These are ideal if you want to find the instance running high CPU usage amongst all the instances in your cluster.
Maps identify where requests are coming from. These are ideal for geolocation data.
Only map charts are supported.
Text can clarify what you're showing on dashboards or act as a note to your viewer. Text panels provide the flexibility to create Text Panels to display descriptive text, and Title Panels to display above Data Panels.
Title Panels are displayed in the same size and font. Text Panels are styled using Markdown syntax, meaning that you can control the size and weight of the text. Not all Markdown syntax options are supported; see Markdown Syntax.
There's no limit to the number of Text or Title Panels you can add to Dashboards. These types of Panels don't count against the quota in Sumo Logic Free accounts.
To add a Text Panel:
- With the Dashboard open, click the Add Panel button.
- Choose Text as the Panel Type.
- The Panel Details pane is displayed.
- A title is optional. Use the toggle switch labeled Show Title to set if the title is displayed. If desired, enter a title and set the font size.
- Next, select the Display menu option.
- Select the Format of the data, either Text or Markdown syntax. See Markdown Syntax for details on what is supported.
- Input your text or markdown, this is what the panel will display.
- The Format options allow you to adjust the font, colors, and alignment of your data.
- When you're done click Add to Dashboard.
Add links to text panels
Text panels can provide links to URLs or other Dashboards with markdown syntax. To create a link to a URL, surround your linked text with square brackets, then add your URL in parenthesis, as shown.
To add a link to a Panel in order to drill down to another Dashboard, see Add Dashboard Link.
In the panel, the link is displayed.
