Welcome to the Logstash guide! Logstash is an open-source data processing pipeline that allows you to collect, transform, and transport data from a variety of sources. It's a powerful tool for managing large volumes of data and is widely used for log management, data integration, and data analytics.

Key Features

  • Data Collection: Logstash can collect data from a wide range of sources, including files, databases, and message queues.
  • Data Processing: It provides powerful data processing capabilities, including filtering, enriching, and modifying data.
  • Data Transport: Logstash can transport data to a variety of destinations, such as Elasticsearch, Hadoop, and more.

Getting Started

To get started with Logstash, you can follow these steps:

  1. Download and Install Logstash: You can download Logstash from the official website.
  2. Create a Configuration File: Logstash uses configuration files to define how data is processed and transported. You can create a configuration file using the following format:
input {
  file {
    path => "/path/to/log/file.log"
    start_position => "beginning"
  }
}
filter {
  mutate {
    convert => {
      "message" => "string"
    }
  }
}
output {
  stdout { codec => rubydebug }
}
  1. Run Logstash: Once you have created your configuration file, you can run Logstash using the following command:
bin/logstash -f /path/to/your/config/file.conf

Example Configuration

Here's an example configuration that collects log data from a file and outputs it to stdout:

input {
  file {
    path => "/path/to/log/file.log"
    start_position => "beginning"
  }
}
filter {
  mutate {
    convert => {
      "message" => "string"
    }
  }
}
output {
  stdout { codec => rubydebug }
}
