Hi all,

I have installed logstash 8.4.0. with my ES.

I have created logstash .conf file to create data pipelines.

I use below .conf format

```auto
input {
...
}

filter{
....
}

output{
...
}

```

I just want to know is above script a custom script format for logstash or is it some scripting language that we are using like JS ?

Custom based on ruby. JS is not supported. [Here](https://www.elastic.co/blog/a-practical-introduction-to-logstash) is a little intro.
