Hi All,

I am inserting data to logstash(collector) via nxlog(sender) to single port. The logs are already parsed on nxlog side from .xml to json , these parsed doc contains logs from different application such as apache, tomcat etc. I have field named as Log\_type to apache or tomcat.

So I want to set a statement to check if the Log\_type = apache send to Index-Apache , If Log\_type = tomcat send to Index\_tomcat.

My Logstash conf is:

input {  
tcp {  
codec =\> json\_lines{ charset =\> CP1252 }  
port =\> 9514  
tags =\>["tcpjson"]  
}  
}

output {  
if "Log\_Type" == [apache\_Logs} {  
elasticsearch {  
hosts =\> ["localhost:9200"]  
action =\> 'index'  
index =\> 'apache-%{+YYYY.MM.dd}'  
}  
if "Log\_Type" == [tomcat\_Logs} {  
elasticsearch {  
hosts =\> ["tomcat:9200"]  
action =\> 'index'  
index =\> 'tomcat-%{+YYYY.MM.dd}'  
}  
}

I am not using filter statement since the logs are parsed with field names. How could I look into data and enable the condition statements.

Thanks,  
Yash

Hey,

Your syntax is actually malformed. Does logstash start with it?  
It should be

```auto
output {
    if [Log_Type] == "apache_Logs" {
        elasticsearch {
            hosts => ["localhost:9200"]
            action => 'index'
            index => 'apache-%{+YYYY.MM.dd}'
    }
    if [Log_Type] == "tomcat_Logs" {
        elasticsearch {
            hosts => ["tomcat:9200"]
            action => 'index'
            index => 'tomcat-%{+YYYY.MM.dd}'
    }
}
```

Thanks for your quick reply. I tried this but no success But I will give a try again. Should I need to inspect the doc using filter section or just in output section?

If the event is already parsed and structured, there is no need for a filter section.  
Based what you said above,

> [@yasvanth](#):
>
> ...I have field named as Log\_type to apache or tomcat.

There should be fields inside the event JSON document like so:

```auto
{
    #other event fields
    "Log_type": "apache_Logs"
}
```

Is that the case? If so, it should work as-is.

@paz thanks a million. It is small typo in the field in nxlog, fixed and now working fine. Thanks for your help.
