Amareshwari Sriramadasu updated LENS-283:
-----------------------------------------
Status: Patch Available (was: In Progress)
The changes include :
* Adds query level configuration to instrument estimate flow
* Methods instrumented to create gauges to measure time taken in nano seconds -
because the time taken for each method can vary with query passed, we would
like to have granular/actual values of time taken in each method than having
timer/meter metrics. There is always scope for getting aggregated values from
granular values.
* Moved metrics related common classes to lens-server-api so that they can be
used in other modules
** Adds static registry available for rewriters and drivers.
> Add latency metering for each resolver in cube query rewriter
