Hey Guys,

We have logstash using redis input plugin, and use pattner\_channel to match multiple channels, how to get the info to the either event or message.

I see people post same question and use add\_field, but those example with static key, not dynamic, just want to know if this is supported.

for example:

input {  
redis {  
host =\> "127.0.0.1"  
type =\> "redis-input"  
data\_type =\> "pattern\_channel"  
key =\> "logstash\*"  
format =\> "json\_event"  
}  
}

and we have following matched pattern, how to add that to the message or event ?

1. "logstash-nodelog-2014.03.07.17"
2. "logstash-javalog-2014.03.07.15"
3. "logstash-applog-2014.03.07.14"
4. "logstash-catalina-2014.03.08.23"
5. "logstash-applog-2014.03.08.23"
6. "logstash-catalina-2014.03.07.15"
7. "logstash-nodelog-2014.03.07.14"
8. "logstash-javalog-2014.03.07.14"
9. "logstash-nodelog-2014.03.08.23"
10. "logstash-applog-2014.03.07.15"
11. "logstash-javalog-2014.03.08.23"
