Profiling

Returns the count of executions and total execution time for an MDX expression. 

Function Profiling works with Mondrian's request profiling enabled. Available for Jira Server / Data Center since eazyBI version 6.5.0

Syntax

Profiling(String_Expression, Value_Expression)

Arguments

String_ExpressionMDX expression that returns a string
Value_ExpressionMDX expression that returns a number, a set, or a string.

Examples

Here is an example formula using Profiling. It uses the function three times, profiling the total count and execution time of the measure, and then separates parts of it - profiling filter and measure usage separately. 

Profiling(
  'Issues created and resolved in period',
  NonZero(
    Sum(
      Filter(
        Descendants([Issue].CurrentHierarchyMember, [Issue].[Issue]),
        Profiling(
          'Filter', 
          DateInPeriod( 
            [Measures].[Issue created date],
            [Time].CurrentHierarchyMember
          )
          AND
          DateInPeriod( 
            [Measures].[Issue resolution date],
            [Time].CurrentHierarchyMember
          )
        )
      ),
      Profiling(
        'Measure',
        [Measures].[Issues created]
      )
    )
  )
)

Here are the profiling results for a measure Issues created and resolved in period in the example report Issues created and resolved in period % in our demo account.

During profiling, the report used only this measure. The example report profiling represents results on a clear cache: 

Filter invoked 45425 times for total of 287ms. (Avg. 0ms/invocation)
DescendantsSet invoked 2 times for total of 1ms. (Avg. 0ms/invocation)
SumFunDef invoked 26 times for total of 482ms. (Avg. 18ms/invocation)
Issues created and resolved in period invoked 26 times for total of 482ms. (Avg. 18ms/invocation)
Measure invoked 346 times for total of 3ms. (Avg. 0ms/invocation)
FilterFunDef invoked 46 times for total of 476ms. (Avg. 10ms/invocation)
SqlStatement-SqlMemberSource.getMemberChildren invoked 1 times for total of 5ms. (Avg. 5ms/invocation)
SqlStatement-Segment.load invoked 1 times for total of 21ms. (Avg. 21ms/invocation)
SqlStatement-SqlTupleReader.readTuples [[Issue].[Issue]] invoked 1 times for total of 63ms. (Avg. 63ms/invocation)

Execution time: 521ms

Here are three profiling results related to the formula extracted from all profiling results visible above. 

  1. Filter invoked 45425 times for total of 287ms.  (Avg. 0ms/invocation)
  2. Issues created and resolved in period invoked 26 times for total of 482ms.  (Avg. 18ms/invocation)
  3. Measure invoked 346 times for total of 3ms.  (Avg. 0ms/invocation)

Filter is applied on all imported issues in the account for any selected period in the report (current and last 12 months). Measure is applied on a filtered set of issues only. Issues created and resolved in period represent executions for each selected period. Any expression is executed twice on the clear cache.
