How long analysis systems such as Elasticsearch, Logstash, and Kibana Stack handle
ingesting unstructured logs from different devices in various formats?

A.

All devices that generate syslogs must use agents that process the local logs and
transmit them in a specific format to the ELK Stack

B.

All logs are stored in their unstructured text format, and the ELK Stack performs data
analysis by intelligently parsing the logs using machine learning algorithms.

C.

All different message formats are parsed separately using custom filters, and the
resulting structured data is stored for later analysis.

D.

A single, comprehensive log format is defined on the ELK Stack. All incoming logs,
regardless of format, are transformed to match the comprehensive format, and only
applicable fields are populated.
