       10.4: Parsing of PMU event table metrics with fake PMUs             : Ok
      ...
       68: Parse and process metrics                                       : Ok
      ...

       89: perf all metricgroups test                                      : Ok
       90: perf all metrics test                                           : FAILED!

    Test 90 failed for Load_Miss_Real_Latency with <not counted> events:
    
     Performance counter stats for 'system wide':
    
         <not counted>      mem_load_uops_retired.hit_lfb                                     (0.00%)
         <not counted>      MEM_LOAD_UOPS_RETIRED.L1_MISS                                     (0.00%)
         <not counted>      L1D_PEND_MISS.PENDING                                         (0.00%)
           1002638743 ns   duration_time
    
    This is exposing a somewhat known issue with weak groups that can
    be worked around with:
    
    $ perf stat --metric-no-group -M Load_Miss_Real_Latency -a sleep 1
    
     Performance counter stats for 'system wide':
    
               9539883      mem_load_uops_retired.hit_lfb #    25.87 Load_Miss_Real_Latency   (83.24%)
              10876212      MEM_LOAD_UOPS_RETIRED.L1_MISS                                     (66.68%)
             528172960      L1D_PEND_MISS.PENDING                                         (83.26%)
