How this ui repo is used
Language implementations should clone this repo as a submodule.
MiniProfiler data structures
This document specifies the MiniProfiler data structures. New languages should use this as the implementation specification.
Profile
The root element.
- Id (string) - a unique identifier, like a guid
- Name (string) - request name, generally
Controller/Route - Started (number) - request start time, in milliseconds since Unix epoch
- DurationMilliseconds (number) - duration of request in milliseconds
- MachineName (string) - name of the server
- CustomLinks (object, optional) - object of links; keys are names, values are URLs
- Root (Timing, optional) - root timing object
- ClientTimings (ClientTimings, optional) - client timings object
Timing
- Id (string) - a unique identifier, like a guid
- Name (string) - step name
- StartMilliseconds (number) - step start time, in milliseconds since start of request
- DurationMilliseconds (number) - duration of step in milliseconds (including children)
- Children (array of Timing, optional) - array of child steps
- CustomTimings (object, optional) - object with keys as call type ("redis", "sql", etc.) and values as arrays of CustomTiming of recorded calls (does not include child step's custom timings)
CustomTiming
- Id (string) - a unique identifier, like a guid
- ExecuteType (string, optional) - execute type of call ("read", "write", "query", etc.)
- CommandString (string) - HTML-escaped command; rendered in a pre, so supports newlines
- StackTraceSnippet (string) - shortened, one-line stack trace; generally all function names on the stack separated by a space
- StartMilliseconds (number) - call start time, in milliseconds since start of request
- DurationMilliseconds (number) - duration of call in milliseconds
- FirstFetchDurationMilliseconds (number, optional) - duration in milliseconds of the time to first result
ClientTimings
This data should be recorded by the browser and reported back to MiniProfiler.
- RedirectCount (number) - redirect count
- Timings (array of ClientTiming)
ClientTiming
- Name (string)
- Start (number)
- Duration (number)
