Hello,

I would like to send **only** active directory logs with **specific Id** from logstash to

Elasticsearch.

Please! What config do I need to do at logstash configuration file to achieve this?

example of event\_Id:"4625"===\> "An account failed to log on",

thanks!!!!

The simplest way to do it is to wrap your `elasticsearch` output in a conditional:

```auto
input {
  # ...
}
filter {
  # ...
}
output {
  if [event_Id] == "4625" {
    elasticsearch {
      # ... Elasticsearch output config
    }
  }
}

```

It can get a bit cumbersome though, especially if your logic about whether or not to export an event gets complex; instead, I would change my logic to output on the presence of a _tag_ (say, `export`), and would add a filter to inject this tag; that way when business requirements change and I need to export more things, I can just add simple statements to tag them and not worry about making a more complex conditional:

```auto
input {
  # ...
}
filter {
  # ...
  if [event_Id] == "4625" {
    mutate {
      add_tag => ["export"]
    }
  }
}
output {
  if "export" in [tags] {
    elasticsearch {
      # ... Elasticsearch output config
    }
  }
}

```

Use the Winlogbeat Beats agent. You can specify which logs and event IDs you'd like to have sent over.

```
winlogbeat.event_logs:
  - name: Security
    event_id: 4624, 4625, 4700-4800, -4735
```
