Source code | Questions, Bugs or Suggestions | My Splunk apps


This visualisation expects tablular data, with any amount of text/category columns, but the last column should be the numerical value. Null or blank columns are allowed before the final column to create a more "sunburst-y" visualization.

The typical search uses stats command like so:

index=* | stats count BY index sourcetype source

Sidenote: a much faster search to do the same thing is

|tstats count where index=* BY index sourcetype source

Note that stats does not return rows when the group BY field is null. Use this one simple trick to convert nulls to be an empty string instead:

index=_internal | eval component = coalesce(component,"") | eval log_level = coalesce(log_level,"") | stats count by sourcetype component log_level

Add more fields after the "BY" keyword to increase the depth of the sunburst

Formatting options

The "Color overrides" field accepts either a JSON object (in curly braces) or comma separated pairs. For example to make sure that "INFO" values are green, WARN's are orange and ERROR's are red, set the value like so:
