Which sections can exist in a Logstash configuration file?

A Logstash configuration file is typically divided into three main sections: input, filter, and output. Each section serves a distinct purpose in the data processing pipeline.

input: This section defines where Logstash will collect data from, such as files, syslog, or beats.

filter: This section processes the data collected from inputs. It can include parsing, modification, and enrichment of the data using various filter plugins.

output: This section specifies where the processed data should be sent, such as Elasticsearch, files, or other endpoints.

The other options are incorrect:

D. forward: This is not a standard section in Logstash configuration.

E. generate: This is not a standard section in Logstash configuration.
