## Hello everyone, I'm new to logstash and I'm learning to write configuration files. As the example goes:

## input { stdin { } } filter { grok { match =\> { "message" =\> "%{COMBINEDAPACHELOG}" } } date { match =\> ["timestamp" , "dd/MMM/yyyy:HH:mm:ss Z"] } } output { elasticsearch { host =\> localhost } stdout { codec =\> rubydebug } }

## I alwasy get a warning "JNA not found. native methods will be disabled" even after I installed 'libjna-java' on my ubuntu. Logstash prints like this:

## Picked up JAVA\_TOOL\_OPTIONS: -javaagent:/usr/share/java/jayatanaag.jar [2015-08-27 20:13:24.549] WARN -- Concurrent: [DEPRECATED] Java 7 is deprecated, please use Java 8.

But when I remove the line "elasticsearch..." in the output block, everything goes fine.  
Why does it happen and how to solve this problem?  
Also, as you can see, it reports a problem "Failed to install template" as well. How can I deal with that?  
Thanks a lot~

Either elasticsearch is not running, or is not running on localhost on the default port.

I am sure Elasticsearch running on port 9200.  
And I can post date using the following shell command  
curl -XPOST [http://localhost:9200/logstash-2015.06.21/testlog](http://localhost:9200/logstash-2015.06.21/testlog) -d '{  
"user" : "chenlin7",  
"mesg" : "first message into Elasticsearch"  
}'
