Hello, it is my first question, if there is something wrong, please forgive me.

I present my problem to you: My Logstash I get logs from Sophos XG. The sophos logs reach me in the "message" field, so with the filter, grok and match option I extract them. Then the output sent me to elasticsearch. What I want is to evaluate the "status" field in a conditional, and if it is "Deny" I also sent them to my **Splunk**. The latter is what I can't do. Can you help me? Thank you. I leave my code so they can review it:

input {  
udp {  
port =\>515  
type =\> "sophos\_log"  
}  
}

filter {  
if [type] == "sophos\_log"{  
grok {  
match =\> { "message" =\> 'log\_subtype="%{NOTSPACE:log\_subtype}"' }  
}  
grok {  
match =\> { "message" =\> 'status="%{DATA:status}"' }  
}  
grok {  
match =\> { "message" =\> "priority=%{NOTSPACE:priority}" }  
}  
}  
}

output {  
if [type] == "sophos\_log" {  
elasticsearch {  
hosts =\> ["\<host\_ip\>:\<host\_port\>"]  
index =\> "sophos-xg"  
}  
}

if "%{[status]}" == "Deny" {  
udp {  
host =\> [""]  
port =\> ["\<host\_port\>"]  
}  
}  
}  
}

The extracted fields do reach elasticsearch well, but the conditional does not evaluate my "status" field, and nothing reaches Splunk. However, I remove the conditional, if the logs are forwarded to Splunk. Can you help me, thanks.

I think that test should be

```
if [status] == "Deny" {
```
