Hi,

I'm trying to add "type" field that i would be able to use as tag when filtering to my input plugin.  
For example, I can add "type" in the 'file' input plugin, and filter it later.  
Code:

> input {  
> file {  
> path =\> "/var/log/%{type}.%{+yyyy.MM.dd.HH}"  
> **type =\> "myType"**  
> }  
> }

> filter {  
> **if [type] == "myType"**  
> ...  
> }

> output {  
> ...  
> }

I looked at the file input plugin implementation, and did not see any field related to the "type" field.

So i just tried to add it like this:

> input {  
> myPlugin {  
> path =\> "/var/log/%{type}.%{+yyyy.MM.dd.HH}"  
> **type =\> "myType"**  
> }  
> }

But the filtering did not work at all.

How can i add this "tag" (or whatever it is) to my plugin?

It sounds like your input plugin doesn't call `decorate()` on the event object before passing it to the output queue, but since you're not showing us your code we can only guess.

Thank you for the answer magnus, And you are correct, i do not call decorate because it crashes for some reason every time i call it.  
This is the error:

`[LogStash::Runner] FATAL logstash.runner - An unexpected error occurred! {:error=>#<NoMethodError: undefined method decorate for #<QueryExecuter:0xabb6bd>>,`

I'm not going to continue debugging this without seeing the code.
