      Metadata integration · ea1ab2b2
      Alessio Netti authored
      - Metadata is now parsed from config files, sent from Pushers to
      Collectagents as JSON, and finally written to Cassandra

      Changes to metadata packet send method · dcafa065
      Alessio Netti authored
      - JSON metadata is sent only if a "metadata" block for the sensor is
      defined, else if auto-publish is enabled we only send the sensor name

      Analytics: fixes and small changes · de38e004
      Alessio Netti authored
      - Fixed a bug that prevented relaxed mode from working properly for
      operators deployed on the collectagent
      - Changed the function of the "delay" parameter: it now specifies a
      fixed offset applied to the computation interval of each operator,
      useful to tune the flow of data in operator pipelines

      Analytics: added job filtering · 584093ba
      Alessio Netti authored
      - A regular expression (jobFilter) can be applied to the jobs' nodelists
      to identify the jobs that need to be treated by each collectagent in a
      - By default only the first node in the nodelist is considered, but this
      behavior can be customized

      Analytics: minor changes to QueryEngine · 02abd6cd
      Alessio Netti authored
      - querySensor does not return NULL pointers anymore, but always
      the "buffer" input argument
      - the previous implementation was more descriptive of error statuses,
      but much more prone to leaking memory in case of improper usage
      - Also fixed a warning in the MSR plugin

      Analytics: bugfixes for job analyzers · 2564afba
      Alessio Netti authored
      - Fixed a fair amount of bugs related to job analyzers
      - Added a "getJobsInIntervalRunning" method to JobDataStore, to get
      the list of jobs that were running in a certain time interval
      - Some code refactoring for the JobDataStore class to reduce duplication
      - Job analyzers have been tested and are working properly as of now

      Analytics: Aggregator plugin re-worked · 6d2b07a0
      Alessio Netti authored
      - Now supports also standard deviation and percentile computation
      - Multiple output sensors per analyzer can be defined, each performing
      a different aggregation task
      - QueryEngine has been slightly modified so as not to clear the input
      sensor reading buffer (if any), thus allowing to accumulate sensor
      values with subsequent calls

      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

      REST API fixes for topics · 1ee72f08
      Alessio Netti authored
      - By convention, users should supply '.' characters instead of '/' when
      querying sensor topics over the REST API to avoid conflicts with URL
      parsing; the characters are then replaced automatically in the server

      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

      Configuration tweaks · 8b4b1738
      Alessio Netti authored
      - Parsing of host:port network addresses is handled by GlobalConfiguration

      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: search-based sensor queries · eb186235
      Alessio Netti authored
      - When performing sensor queries with absolute timestamps (rel=false) a
      binary search algorithm is used to compute the bounds of the required
      sensor cache view
      - This is more accurate than the fuzzy method employed with relative
      timestamps (rel=true)
