How to stats ratio based on two fields

[cheriemilk]

Hi team,

I have a below sample raw events in splunk.

2020-11-30 19:15:26,726 ratingEnabled="[performance]"

2020-11-30 15:59:13,827 ratingEnabled="[objective,competency]" ratingEnabledGuideline="[objectiveGuideline]"

2020-11-30 05:34:40,986 ratingEnabled="[performance]" ratingEnabledGuideline="[performanceGuideline]"

stats requirement:

I want to get a ratio that enabled guideline per each rating. For example: analyze above sample events,

1. there are 3 ratings enabled(refer to ratingEnabled field): performance, objective and competency

2. there're 2 ratings enabled guideline(refer to ratingEnabledGuideline field): objective and performance

So the expected result I want splunk to return is:

ratingEnabled	count	count - enabled Guideline	ratio - enabled guideline
performance	2	1	50%
objective	1	1	100%
competency	1	0	0%

How to stats the ratio in this scenario?

| rex max_match=0 field=ratingEnabled "(?<ratingEnabled>[^\[,\]]+)"
| mvexpand ratingEnabled
| rex field=ratingEnabledGuideline "(?<guideline>[^\[]+)Guideline"
| eval guided=if(ratingEnabled=guideline,1,0)
| stats count sum(guided) as guided by ratingEnabled
| eval ratio=guided*100/count
