Assigning a variable to field values consolidated by wildcard

[smutherbavaro]

I'm trying to wrap my head around assigning a variable to field values that have been consolidated by wildcard. The specific field is a url which contains unique values, but can be consolidated by wildcard:

/api/v1/data/dataInfo/5034542340/0031f24ea10c/867542388
/api/v1/data/dataInfo/6134191727/0031f24ea10c/1353781841
/api/v1/data/validate

Each of these has statusCode, timestamp, etc fields associated. I am needing to do a count of how many times /api/v1/data/dataInfo/* had a 404 response, and how many times /api/v1/data/validate had a 404 response, ideally in a timechart. Without consolidating to a wildcard, I have hundreds of results, because the hash that I'm consolidating via wildcard is unique.

I've tried the following, but it errors on "Error in 'eval' command: The expression is malformed. An unexpected character is reached at '/api/v1/data/dataInfo/*)'." I take this to mean I can't use eval/if with a wildcard.

 index=data_index environment=Production clientName="DataTool" statusCode=404
| eval dpInfo = if(url=/api/v1/data/dataInfo/*) 
| eval validate = if(url=/api/v1/data/validate) 
| timechart count

Any ideas would be very much appreciated!

Like this:

index=data_index environment=Production clientName="DataTool" statusCode=404
| timechart count(eval(match(url, "^/api/v1/data/dataInfo/"))) AS dpinvo
            count(eval(match(url, "^/api/v1/data/validate$"))) AS validate

Is it * or .* or % in the context of match?

[woodcock]

Good point; I should not have had the * there at all (I modified my answer). I could have put in .* but it would have been redundant for the need and waste effort for the RegEx parser.

To use wildcards in eval, use the match or like function.

... | eval dpInfo = if (match(url,"/api/v1/data/dataInfo/.*") | ...

... | eval dpInfo = if (like(url, "/api/v1/data/dataInfo/%") | ...
