Production Mode Now Defaults to LOGSTASH_MINIMAL For New Deployments
Please note that the new version of Setup now defaults to LOGSTASH_MINIMAL for new Production Mode deployments. LOGSTASH_MINIMAL means that Logstash transports unparsed logs to Elasticsearch where they are parsed using ingest node parsing, which results in better performance. Here are a few examples:
- If you choose Production Mode and New to create a master server, then Setup will set LOGSTASH_MINIMAL in /etc/nsm/securityonion.conf on your master server.
- If you then add a storage node to that master server, it will inherit the LOGSTASH_MINIMAL setting from the master server.
- If you have an existing deployment without LOGSTASH_MINIMAL (traditional Logstash parsing), then if you add new nodes they will continue using traditional Logstash parsing.
- Evaluation Mode is unchanged and will continue to use traditional Logstash parsing.
