Hello All,

I am facing major issue with logstash after migration from 7.9.1 to 8.8.2 version.  
Elasticsearch/Logstash 8.X version has ECS compatibility enabled by default.This adds new field  
**event.original** in every document indexed in elasticsearch from logstash.  
To ignore above field i.e event.original we've added **pipeline.ecs\_compatibility: disabled** in logstash.yml and it eliminates required field.

But it also eliminates other necessary fields like **host.name** (This value is required by us)  
Plz suggest us some solution how to handle this .

Thanks

You could use

```
mutate { remove_field => ["event"] }

```

or

```
mutate { remove_field => ["[event][original]" ] }

```
