Configuration and Performance
=============================

Files Processing Configuration
""""""""""""""""""""""""""""""
The PM Mapper consumes the 3GPP XML files from DMaaP-DR, and processes them. It is possible to process it in parallel.
In order to parallel processing, new configuration env has been introduced:

- PROCESSING_LIMIT_RATE (optional, default value: 1) - allows to limit the rate of processing files through channel.

- THREADS_MULTIPLIER (optional, default value: 1) - allows to specify multiplier to calculate the amount of threads.

- PROCESSING_THREADS_COUNT (optional, default value: number of threads available to JVM) - allows to specify number of threads that will be used for files processing.


Envs should be specified in section "envs:" in blueprint. Example part of blueprint configuration:

::

        ...
        pm-mapper:
          type: dcae.nodes.ContainerizedServiceComponentUsingDmaap
          interfaces:
            cloudify.interfaces.lifecycle:
              create:
                inputs:
                  ports:
                    - '8443:0'
                    - '8081:0'
                  envs:
                    PROCESSING_LIMIT_RATE: "1"
                    THREADS_MULTIPLIER: "2"
                    PROCESSING_THREADS_COUNT: "3"
          relationships:
            - type: dcaegen2.relationships.subscribe_to_files
              target: pm-feed
            - type: dcaegen2.relationships.publish_events
              target: pm-topic
        ...


PM Mapper Filtering
"""""""""""""""""""
The PM Mapper performs data reduction, by filtering the PM telemetry data it receives.
This filtering information is provided to the service as part of its configuration, and is used to identify desired PM measurements (measType) contained within the data.
The service can accept an exact match to the measType or regex(java.util.regex) identifying multiple measTypes (it is possible to use both types simultaneously).
If a filter is provided, any measurement that does not match the filter, will be ignored and a warning will be logged.
PM Mapper expects the filter in the following JSON format:

::


         "filters":[{
            "pmDefVsn": "1.3",
            "nfType": "gnb",
            "vendor": "Ericsson",
            "measTypes": [ "attTCHSeizures", "succTCHSeizures", "att.*", ".*Seizures" ]
         }]

                       defined and should match the
                       string used in file ready
                       eventName.
measTypes              Measurement name used in PM       List of Strings, Regular expressions
                       file in 3GPP format where
                       specified, else vendor
                       defined.
