Question

BlackTom AI · Accepted Answer

The question asks which tools are used to redirect, gather, process events and register messages.
Option a: Prometheus. This tool is primarily a monitoring and alerting system focused on collecting metrics from services, not a general log/event processing pipeline. It does not redirect or register messages in the way a log pipeline would, so this is not correct for the asked context.
Option b: Logstash. Logstash is a data processing pipeline used to collect, parse, transform, and forward logs and events. It directly fits the description of redirecting, gathering, and processing events and preparing them for storage or analysis, making this correct.
Option c: Elasticsearch. Elasticsearch is a search and analytics engine that stores and indexes data, including logs, but it does not by itself function as a pipeline to redirect or process events. It receives data from pipelines like Logstash, but on its own it does not perform the gathering/processing/redirecting steps described. This makes it incorrect as the standalone tool described in the question.
Option d: ELK stack. The ELK stack combines Elasticsearch, Logstash, and Kibana. In this collection, Logstash handles the gathering and processing of events, Elasticsearch stores and enables searching/analyzing the data, and Kibana provides visualization. Since ELK represents the complete set that enables redirecting, gathering, and processing of events and registering messages within the stack, this is correct.
In summary, option b correctly identifies Logstash as the processing component, and option d correctly identifies the ELK stack as the full suite that encompasses the described capabilities. Options a and c do not fully satisfy the role of an end-to-end event redirection/processing pipeline on their own.
