Ok I remember what this plugin does. Actually there is no such plugin because it wont work. If you want push some metrics to dynatrace you can write custom piece of code that will do it for you over API. If you want execute something as a result of problem rising, you have to create piece of code that will serve HTTP service. Then from Dynatrace => Custom integration you can send json payload via POST to this WebService. Then you can handle this event to execute some command on monitored host. You will not make it in any other way I think.
