👉 Logstash.conf is a configuration file for a log processing tool called Logstash, used in the Amazon Web Services (AWS) environment. It's primarily used to configure the process of transforming data from various sources into an organized format ready for analytics. The key features include:
1.
Source Configuration:
This allows you to specify the source of logs, which includes file input, streaming input, or a custom input type.
2.
Processing Pipeline:
Here, you define the processing steps within your log transformation process. It's typically implemented in the form of a sequence of transformations (e.g., `transform(awslogs:logs)`).
3.
Output Format:
This specifies how the transformed data should be delivered to a destination.
4.
Data Sources and Conditions:
These allow you to specify whether specific conditions apply on incoming data, or whether it's an ordered list of records.
The word "logstash" comes from the Greek word 'logos' which means 'word', and 'stixis' which means 'to split'. This gives us a concise summary of the main components of Logstash: the 'log' that logs events, 'stash' for storage, and 'streaming' to transform data into structured output.
