      Bugfixes · 596c4c94
      Alessio Netti authored
      - Removed the dlclose call on plugin unloads to avoid segmentation fault
      issues at destruction time of boost thread objects due to failed symbol resolution
      - QueryEngine in DCDBPusher does not block anymore while being updated,
      but simply returns NULL

      Documentation and fixes · 69739f0a
      Alessio Netti authored
      - Added documentation to the new SensorID implementation
      - NOTE: virtual sensors will likely require some modifications due to
      how topics are handled now ('/' separator clashing with divide symbol)

      Fully-operational string MQTT topics · b45ce395
      Alessio Netti authored
      - String topics are now used across all of DCDB, up to Cassandra
      - As of now, sensor names ALWAYS match MQTT topics
      - Users can still define sensor "aliases" via dcdbconfig that point
      to the same topics

      DA: filter for SensorNavigator and binary search fixes · f2970bda
      Alessio Netti authored
      - a "filter" configuration parameter has been added, which is used
      to discard sensor names when building the sensor navigator
      - Can be used to e.g. build a sensor navigator in a collectagent
      using only the sensors that are directly collected by it
      - Implemented a switch to select leftmost/rightmost binary search
      in CacheEntry, used for the QueryEngine

      Hyperthreading aggregation in ProcFS · 476dec13
      Alessio Netti authored
      - Virtual threads can now be automatically aggregated for procstat and
      sar groups
      - the htVal parameter is the number of physical threads; corresponding
      virtual threads are determined via modulo arithmetic
      - Minor changes to AnalyticsController in collectagent

      Unified configuration backend · 0b344fc2
      Alessio Netti authored
      - The GlobalConfiguration class includes all shared logic to read and
      parse configuration attributes for the collectagent and dcdbpusher
      - The class is further expanded to add application-specific
      configuration parameters and blocks

      DA: REST API in collectagent · 0466b434
      Alessio Netti authored
      - The REST API of the data analytics framework is now functional in
      the collectagent as well
      - This implementation is temporary and should be replaced with a generic
      REST API server whenever possible

      DA: integration of analytics in collectagent · 30c355d3
      Alessio Netti authored
      - QueryEngine integration done (but not functional yet, debugging required)
      - Changed behavior on exceptional conditions: if SensorNavigator or
      AnalyticsManager initialization fails, termination follows
      - Now the QueryEngine can also access output sensors of other Analyzers
      - Minor bugfixes

      DA: integration in CollectAgent (WIP) · 0f77d784
      Alessio Netti authored
      - First step for integration of the analytics framework in the collectagent
      - QueryEngine and REST API integration still missing
      - Proper testing still to be done
      - Added a probe function: the global config file is scanned before
      initialization, and if no data analytics plugins are requested, no
      sensor navigator is built
