I am trying to Monitor our Tomcat logs with Elastic Search / LogStash

when i try and create a mapping:

curl -XPUT "http://:9200/logs/" -d '{ "mappings" : { "tomcat\_access":{ "discover":".\*"}}}'

I am getting the following Error:

{"error":"Content-Type header [application/x-www-form-urlencoded] is not supported","status":406}root@ip-10-239-48-161:/etc/logstash/conf.d#

That is default content type for a curl PUT. You should use:

```
curl -X PUT "localhost:9200/[...]" -H 'Content-Type: application/json' -d'[...]'

```
