  9. MR 2 - COSMOS DC • Architecture • Components • Data and Meta Data • Demo

  10. MR 2 Data Format • SDMX • Data (e.g. performance data) • Meta Data (e.g. resource types) • Reference Meta Data (e.g. system types) • SDMX Key Family • Contains meta data that describes multi-dimensional data • Used to construct queries

  11. MR 2 Data Manager interface • SDMX key family information • getAllKeyFamilyNames() • getKeyFamilyByName(String kfName) • queryKeyFamilyData(String kfName, String query )

  12. Device System NT Unix Router Cisco NT Disk # Reads Resource tree # Writes Memory Page Faults SDMX Model in the Client and the Data Managers System type tree the System Type tree is modeled in the SDMX Reference Meta Data (as an SDMX category tree) the Resource tree is modeled in the SDMXMeta Data (as an SDMX key family with dimensions from a concept tree)

  13. Device System System type tree NT Unix Router Cisco NT Disk # Reads Resource tree # Writes Memory Page Faults SDMX Performance Data Query • Query of Performance Data: • Query machine names from the SDMX category tree (of system types) • Query Key Family dimensions (of the resource tree) Example: graph the Page Faults, # Reads, and # Writes for NT device “usilbs01”
