      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

      Sensor name auto-publish feature · 18aae967
      Alessio Netti authored
      - dcdbpusher can now be configured to automatically publish its
      sensors by communicating the MQTT topic -> name mapping to the
      collectagent through appropriate messages
      - See the README for further details
      - As of now, dcdbpusher performs auto-publish (when required to) and
      then proceeds with normal operation; this should be changed so that
      the pusher terminates gracefully after having published the sensors

      Sensor naming changes · b26cd7f3
      Alessio Netti authored
      - Now all sensors across all plugins adopt the naming convention
      cpu<CPUid>.<sensorName>, if CPU-related, or just <sensorname> otherwise
      - Code to parse cpu sets used both in Perfevent and ProcFS plugins
      moved up in ConfiguratorTemplate
      - Misc code to format MQTT parts also moved up in ConfiguratorTemplate

      ProcFS percentage feature · 5e4a0f89
      Alessio Netti authored
      - Added a ProcstatPercParser: similar to ProcstatParser, for each CPU-related line it will collect for each column the percentage of the related value with respect to the sum of all columns, instead of raw values
      - Can be selected by specifying sensor groups of type "procstat_perc"

      ProcFS tiny changes · 1955eec8
      Alessio Netti authored
      - Fixed crash when sensor groups cannot be initialized
      - Column metrics for each CPU in /proc/stat are now disambiguated from those found in other lines (like softirq) and they are defined with the "col_" prefix

      Changes to signal handlers · aa50c30f
      Alessio Netti authored
      - The same signal handler is used for both SIGINT and SIGTERM signals
      - Previously, the SIGTERM handler would not perform any cleanup,
      leading to corruption and issues on the collect agent side

      ProcFS plugin optimization · 3f8b1935
      Alessio Netti authored
      - Most metric name checks in the procstat parser now use plain C string
          matching instead of regular expressions
      - Overhead has been reduced to 1.09% for a full vmstat + meminfo +
          procstat instantiation on a CoolMUC3 node (2700+ metrics each sec)
      - Overhead for a minimal meminfo instantiation is 0.05% (44 metrics)
      - We can safely assume linear scaling of the plugin in function of the
          number of metrics
