How do I configure Logstash for my data pipeline?

To configure Logstash, you'll need to create a configuration file that defines your input, filter, and output plugins.

What are the common input plugins I can use?

Common input plugins include file, beats, and syslog. Each serves different data sources.

Can you give me an example of a configuration file?

Sure! Here's a simple example:

input {
  file {
    path => "/path/to/your/logfile.log"
    start_position => "beginning"
  }
}

filter {
  grok {
    match => { "message" => "%{COMBINEDAPACHELOG}" }
  }
}

output {
  elasticsearch {
    hosts => ["http://localhost:9200"]
    index => "logs-%{+YYYY.MM.dd}"
  }
}

This reads a log file, processes it, and sends it to Elasticsearch.

How do I test my Logstash configuration?

You can test your Logstash configuration by running the command logstash --config.test_and_exit -f your_config.conf. This checks for syntax errors.
