Scalable Vector Graphics - Custom Visualization
Overview
Details
Scalable Vector Graphics - Custom Visualization allows Scalable Vector Graphics (SVG) text generated from Splunk's Search Processing Language (SPL) to be displayed in a dashboard.
Generate any SVG text (statically or dynamically) and put the result into the svg_viz field so the visualisation can display it.
Select the SVG vizualization to display the svg_viz field as a SVG image.
The app contains different dashboard examples showing what can be created with the SVG visualisation.
Example dashboards in menu
- "SVG Examples" / "How Tos" / "Playground" - for simple SVG shapes
- "SVG Examples" / "Showcase" - quick examples of what can be done with this visualization
- "SVG Examples" / "Infrastrucuture Monitoring" - dynamic value/indicators embedded infrastrucutre diagram
- "SVG Examples" / "Where's Wally? (Waldo)" - dynamic map showing locations of people
The app contains macros to display pre-canned battery and counters visualisations.
Example dashboards in menu using SVG macros
- "SVG Examples" / "Battery with Percentages" - percentage value displayed on battery, for example percentage charged
- "SVG Examples" / "Battery with Bars" - use bars on a battery instead of percentages
- "SVG Examples" / "Circles and Squares" - alternative ways to display counters / text
Drilldowns are not supported per se but linking to other urls can be done via adding href links inside the SVG using the syntax <a href="{url_to_link_to}">{svg_tags}</a>
SVG visualizations can be printed directly from the browser or via Export -> Print on the dashboard.
Painting a Picture with Splunk provides an introduction to this app.
