This visualisation expects tabular data, with any amount of text/category columns, but the last column must be a numerical value.

For example, the following data:

field1 field2 field3 numeric_value
outer1 mid1 node1 5
outer1 mid1 node2 4
outer1 mid2 node3 9
outer2 mid3 node4 13

Would produce this:

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. Convert nulls to be an empty string like this:

| 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

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:


The "Set color by" options "First field.." allow for data to set the color of the leaf node but not affect the grouping. The "First field as color codes (n/g)" option allows for valid HTML color codes to be passed in from the search. Here is an example search:

| stats sum(count) as count BY log_level component 
| eval color = case(log_level=="ERROR", "#b22b32",log_level=="INFO", "#1a9035",log_level=="WARN", "#AF5300", true(), "blue") 
| table color component count

Note that when using "Click action" of "Zoom in" the labels are not clipped and will probably overlap.

Third party software

The following third-party libraries are used by this app. Thank you!
