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.
