Hi Folks,

I am trying to achive certain conditions with logstash and wondering \if - if-else statement or validation is possible in Logstash filter?

I have below messages in json and parsing DMARC logs with logstash. I wanted to achieve

```auto
if auth_spf == pass then insert Tag DMARC aligned True
OR
if auth_dkim == pass then insert Tag DMARC aligned True
OR
if auth_spf || auth_dkim == pass then insert Tag DMARC aligned True

```

Can someone please help?

Conditionals can be used to control which filter runs but not be used within filters.

In the Logstash [config file](https://www.elastic.co/guide/en/logstash/7.9/event-dependent-configuration.html).
