+The [logstash](https://github.com/widhalmt/check_logstash) plugin connects to the Node API of Logstash. This feature was introduced with Logstash version 5.0 so the plugin won't work with prior versions of Logstash. The Node API is not activated by default, you will have to reconfigure your Logstash installation for the plugin to connect.
