Default Configuration

If you do not configure the individual writers, the sensor-specific configuration will use the default values. You can choose to use this default configuration by either not creating the Indexing Configuration file or by entering the following in the file. You can name the file anything you like, for example index_config.json, but it must be located at $METRON_HOME/config/zookeeper/indexing.

{
}

If a writer configuration is unspecified, then a warning is indicated in the Storm console. For example, WARNING: Default and (likely) unoptimized writer config used for hdfs writer and sensor squid. You can ignore this warning message if you intend to use the default configuration.

This default configuration uses the following configuration:

  • elasticsearch writer

    • index name the same as the sensor

    • batch size of 1

    • enabled

  • hdfs writer

    • index name the same as the sensor

    • batch size of 1

    • enabled
