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.
