Trend - Size [MB]Visualization displaying the size of data areas - values are rounded to natural numbers

DTP dest. countNumber of DTP requests loaded into an InfoProvider (including reloaded requests from an archive)
DTP dest. relv

Number of requests (DTPs for InfoCubes, activation requests for DSOs) relevant for straggler analysis

  • by a DSO object - request is relevant when a Changelog contains records of this request
  • by an InfoCube object - request is relevant when request records are not compressed
  • by a WODS object - requests aren't relevant, as WODS can be archived only based on a request creation date
  • by an ADSO object - based on the type of the object, the ADSO behaves the same as the equivalent object type (DSO, WODS, InfoCube)
    • as ADSO object can have various settings. In general, the analysis collects requests for the following object types:
      • Data warehouse - the data mart

        • Information is gathered from the Changelog table
DTP stragglers
