      Analytics: various fixes · bec12ea1
      Alessio Netti authored
      - Integrated the "disabled" parameter for operators
      - "operatorPlugin" can be left empty if path and config are default
      - "operatorPlugin" config field is relative to _cfgPath if not absolute
      - Relaxed the operator name uniqueness constraint, duplicated operators
      now have (again) all the same name
      - Minor bugfixes

      Updated subsampling function · bef55e84
      Alessio Netti authored
      - If a subSampling value of 0 or lower is chosen for a sensor, it will
      never be pushed out over MQTT/Cassandra and only kept in memory

      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: sink units · ab3b17e3
      Alessio Netti authored
      - Allowing users to define analyzers with inputs but no outputs
      - In this case, a "sink" unit is created, which always refers to the
      root of the sensor tree
      - This is useful for control analyzers that tune system knobs but do
      not actively produce sensor data

      Analytics: flattening of hierarchical units · 8ea5658d
      Alessio Netti authored
      - For plugins that use hierarchical units (e.g., job analyzers) a
      "flatten" plugin option was added. If enabled, output sensors in the
      sub-units of each unit will be exposed as well, and their output values
      propagated
      - Minor fixes here and there

      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

      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

      - Update config files to reflect new topic structure
      - Updated READMEs accordingly
      - Added support for "relaxed" analyzers, whose units can be built
      even if some sensors cannot be found in the system
      - Added support for sub-units, so as to build hierarchical unit structures

      DA: improved template support · 03527a09
      Alessio Netti authored
      - Now template sensors can be defined in data analytics plugins, and
      can be used both for input and output
      - The list of input "prototype" sensors of a template analyzer is now
      propagated to derived analyzers
      - The list of output "prototype" sensors of a template is ignored and
      not inherited, because it would interfere with the Unit system

      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

      Changes to auto-publish · ad431672
      Alessio Netti authored
      - Auto-publish is now case insensitive with respect to the <sensor> and
      <group> patterns
      - If an invalid pattern was specified (missing <sensor> clause) the
      configuration is aborted
      - Checks for the uniqueness of sensor and group names have been
      temporarily dropped as they interfere with templates and entities
      (until we find a good solution for MQTT topics)

      Minor refinements · abf6af19
      Alessio Netti authored
      - Boolean configuration options now all accept "true" and "on" keywords
      - Cache interval and thread count parameters removed from the command-line
      interface for consistency; these can still be set in the config files
      like all other parameters
      - global.conf file renamed to dcdbpusher.conf for consistency

      MQTT topic checks · 75197e31
      Alessio Netti authored
      - Checks on MQTT topics have been made generic in the MQTTChecker singleton
      class under "common"
      - MQTT topic checks are now performed also when plugins are reloaded; if
      the checks fail, the plugin is cleared and left uninitialized
      - All sensors in a plugin not satisfying the checks are logged now, not
      only the first one
      - Fixed a minor bug that resulted in msgrates of 0 under certain
      compilers, due to type promotion in C++
