This visualisation expects a table of data, with one column called "path". Additional optional columns are listed below.

  • path - this column/field should can be forward-slash delimited, but you can change the delimiter in the formatting options.
  • color - a HTML color code or hex value to use for coloring the node
  • drilldown - when a user clicks a node, the contents of this drilldown field will be set in a token called $dendrogram_viz_drilldown$. See token section below.
  • tooltip - content to show on the tooltip when a user hovers the node
  • names - can be used to change node names. Should be the same 'depth' as the path.

Here is an example search that you can use with web data

index=web | stats count by uri_path | rename uri_path as path

Here is an example of how the data should look


When clicking a node, the following tokens will be set: $dendrogram_viz_path$, $dendrogram_viz_name$, $dendrogram_viz_name$ (see 'names' above) and $dendrogram_viz_drilldown$ (if drilldown column is provided in the data). Hit F12 to open the browser console, to see what tokens are being set.
