I'm trying to aggregate the API logs based on the different endpoints I have. There are a total of 4 endpoints:

1: /v1/vehicle_locations

2: /v1/vehicle_locations/id

3: /v1/driver_locations

4: /v1/driver_locations/id

The way I'm currently doing this is:

_sourceCategory=production | keyvalue auto | where (path matches "/v1/driver_locations" OR path matches "/v1/driver_locations/*" or path matches "/v1/vehicle_locations" or path matches "/v1/vehicle_locations/*") | count by path

The problem with this is that while I get the correct aggregate for /v1/vehicle_locations and /v1/driver_locations, I get individual results for /v1/driver_locations/id and /v1/vehicle_locations/id since the id is a wildcard. Is there a way I can aggregate these wildcards as well?

There are several ways to achieve what you ask. I think the most straightforward one and suggested is to use | parse operator so that you can treat the top-most element of your path as a field, e.g.

_sourceCategory=production
| keyvalue auto 
| parse field=path "*/*" as topmost, rest
| where (topmost = "vehicle_locations" or topmost = "driver_locations")
| count by topmost

Note that by default | parse operator works on the raw message (e.g. the original log line), but you can make it parse a field - using the field= syntax and this is what it's used above.

You might want to tweak the parse expression or use a regex depending on the actual paths you encounter.
