Storm is Not Receiving Data From a New Data Source
If, after installing a new data source, Storm is not receiving data from the data source, there are several configurations you can check.
Ensure that your Grok parser statement is valid.
- Log in to HOST $HOST_WITH_ENRICHMENT_TAG as root.
Deploy a new, valid parser topology:
$METRON_HOME/bin/start_parser_topology.sh -k $KAFKA_HOST:6667 -z $ZOOKEEPER_HOST:2181 -s $DATASOURCE
- Navigate to the Apache Storm UI to validate that the new topology is displayed and without errors.
- Ensure that the Apache Kafka topic you created for your new data source is receiving data.
- Check your Apache NiFi configuration to ensure that data is flowing between the Kafka topic for your new data source and Hortonworks Cybersecurity Platform (HCP).
