Configuring Indexing

The indexing topology is a topology dedicated to taking the data from a topology that has been enriched and storing the data in one or more supported indices. More specifically, the enriched data is ingested into Kafka, written in an indexing batch or bolt with a specified size, and sent to one or more specified indices. The configuration is intended to configure the indexing used for a given sensor type (for example, snort).

Currently, Cloudera Cybersecurity Platform (CCP) supports the following indices:

  • Elasticsearch

  • Solr

  • HDFS under /apps/metron/enrichment/indexed

Depending on how you start the indexing topology, it can have HDFS and either elasticsearch or SOLR writers running.

Just like the Global Configuration file, the Indexing Configuration file format is a JSON file stored in ZooKeeper and on disk at $METRON_HOME/config/zookeeper/ indexing.

Within the sensor-specific configuration, you can configure the individual writers. The parameters currently supported are:


The name of the index to write to (defaulted to the name of the sensor).


The size of the batch that is written to the indices at once (defaulted to 1).


Whether the index or writer is enabled (default true).
