How Logstash Work

Inputs

use inputs to get data into logstash.We can use more tool:

- file:reads from a file

- redis:reads from redis server.

- sql:reads usr SQL from Mysql.

- beats: processes events sent by Beats.

Filters

Filters is a intermediary processing devices in the Logstash pipeline.

• grok: parse and structure arbitrary text. Grok is currently the best way in Logstash to parse unstructured log data into something structured and queryable. With 120 patterns built-in to Logstash, it’s more than likely you’ll find one that meets your needs!
• mutate: perform general transformations on event fields. You can rename, remove, replace, and modify fields in your events.

• drop: drop an event completely, for example, debug events.

  clone: make a copy of an event, possibly adding or removing fields.

• geoip: add information about geographical location of IP addresses (also displays amazing charts in Kibana!)

For more information about the available filters, see Filter Plugins.

Outputs

Outputs are the final phase the Logstash pipeline. An event cna pass through multiple outputs.

• elasticsearch: send event data to Elasticsearch. If you’re planning to save your data in an efficient, convenient, and easily queryable format… Elasticsearch is the way to go. Period. Yes, we’re biased :)
• file: write event data to a file on disk.

For more information about the available outputs, see Output Plugins.
