it same as traditional way to use logback, especially the part we configure to send it to logstash, right?

Yes, you are correct. When you configure Logback to send logs to Logstash, it's often done similarly in both traditional logging setups and setups where Elasticsearch and Logstash are used as part of centralized logging infrastructure.

The key steps, which include configuring Logback to send logs to Logstash, are indeed quite similar:

  1. Logback Configuration: In both scenarios, you configure Logback to format and structure your logs as JSON data, which makes it easier to process logs in a centralized system.

  2. Logstash Appender: You use a Logstash appender in Logback's configuration to specify the destination where logs should be sent. The destination typically points to a Logstash server that acts as a log shipper and forwarder. Logstash is responsible for receiving logs, processing them, and sending them to Elasticsearch for storage and analysis.

Here's a snippet of a Logback configuration that sends logs to Logstash:

<appender name="logstash" class="net.logstash.logback.appender.LogstashTcpSocketAppender">
  <destination>logstash-server:5044</destination>
  <encoder class="net.logstash.logback.encoder.LogstashEncoder" />
</appender>

This configuration is indeed similar, whether you're sending logs to a central Logstash server for further processing and storage in Elasticsearch or using a more traditional log aggregation approach.

The key difference lies in the backend infrastructure where the logs are collected, stored, and analyzed. With Elasticsearch and Logstash, logs are typically stored in a more scalable and searchable manner, which is well-suited for microservices and distributed systems. This centralized approach offers benefits like log aggregation, powerful search, and visualization capabilities, making it particularly useful in modern, complex environments. However, the way you configure Logback to send logs to Logstash remains similar to configuring it for traditional logging setups.
