I want to make sure I identify the that the logs are coming from nginx before processing this grok filter, is this syntax still valid in version 7x?

```
filter {
  if [program] == "nginx_access" {
     grok {
         match => { "message" => "%{NGINX_ACCESS}" }
    }
  }
  elseif [program] == "nginx_error" {
     grok {
         match => { "message" => "%{NGINX_ERROR}" }
    }
  }

```

Or should I use source, my logs are coming via a filebeat shipper
