Existing queries in Application Insights don't work in OMS

Hi,
For example, let custom event be:
track_event('test_drive', {"brand": "foo", "make": "bar"})Somthing I do in Application Insights is a query like such:
customEvents | where name == 'test_drive' | summarize by count() by tostring(customDimensions.brand)
where I do a count of a specific custom event summarized over a field I created for that event.

MicrosoftThere are several ways, here are examples for parse and extract:
parse ('"firstname": "John", "lastname": "Doe"')
with '"firstname": "' firstname '", "lastname": "' lastname '"'
| project firstname, lastname
...| extend custom_value='"firstname": "John", "lastname": "Doe"'
| extend names = extractall('"firstname": "(.*)", "lastname": "(.*)"', custom_value)
| project custom_value, firstname=names[0][0], lastname=names[0][1]
over these you eventually summarize as you prefer.
Just to give you some history. App Insights Connector was created when OMS didn't support json so we had to transform these. In the near future, the need for connector will go away and you should be able to query data directly for e.g. app('foo').events | take 100.
