Hierarchical Tree Structure of KPI
                                            The Performance Monitoring parameters are organized into the following hierarchical tree structure:
/api/v1/kpi
       /current
          /<application>
                 /<group>
                        /global
                               /<pm>
                           /<element>
                               /<id>
                                      /<pm>
       /interval
          /<num>
                 /<application>
                        /<group>
                               /global
                                      /<pm>
                                  /<element>
