      On-demand data analytics · 68a61f34
      Alessio Netti authored
      - By setting the "streaming" attribute to false, users
      can instantiate analyzers that are available only on-demand for requests
      on the REST API
      - The input/output config will be used to instantiate an unit on the fly
      starting from the node queried by the user
      - Computation is performed and the result is returned, no data is pushed
      on MQTT or to the database

      Alessio Netti authored
      - Fixed a minor bug in QueryEngine that broke thread safety
      - The all and all-recursive clauses for unit input sensors do not
      replace all existing sensors anymore, but only add the remaining ones

      - Subsampling behavior with delta fixed: the deltas that
      are sent over MQTT are coherent with the subsampling frequency, and are
      computed separately from the local high-frequency deltas
      - Added exception handling when writing to sensor file sinks
      - Fixed odd ProcFS behavior that led to reading constant values from
      certain files by closing and re-opening every time. Overhead seems to
      be negligible

      Alessio Netti authored
      - Basic framework structure to perform streaming data analytics
      on dcdbpusher
      - Code currently compiles, but is not tested and integration with
      dcdbpusher is still in progress
      - Do not attempt to use this code yet :)

      Sensor subsampling and file output features · d76931a3
      Alessio Netti authored
      - Now sensors can be configured to be automatically written to files
      (sink param)
      - A per-sensor subsampling feature has also been added, allowing to
      decimate the frequency of readings sent to MQTT compared to those that
      have been sampled
      - Also fixed a bug in MQTTpusher that caused reduced message rates

      ProcFS and Tester bugfixes · fee8cc37
      Alessio Netti authored
      - Fixed template management when configuring ProcFS and Tester instances:
      sensors are not inherited from the template, preventing inconsistencies
      - Fixed a bug that caused the "global" config block to be not recognized
      anymore in plugins

      Tester plugin · 56c77a58
      Alessio Netti authored
      - Allows to instantiate an arbitrary number of sensors which output
      incremental values
      - Naming and MQTT topic selection are performed automatically
      - Useful to stress test the collectagent and verify overall performance
