Viewing data with Grafana is quite simple but taking some action not so much. So here is my way of doing it :)
A simple solution is to use a TEXT Panel and inject some HTML with a button and a Javascript code.
Bellow is a sample that will use the $Datasource and perform a GET request on a specific URL "/"
<button class="btn navbar-button gf-timepicker-nav-btn" style="width: 100%" onClick="runGame()">Start</button>
<script>
function runGame() {
var t = angular.element('grafana-app').injector().get('templateSrv');
t.updateTemplateData();
url = t.index.Datasource.datasourceSrv.datasources["$Datasource"].url;
$.get( url + "/" , function( data ) {
$( "#output" ).html( data );
});
}
</script>
<p id="output"></p>
From this point things should be much easier.
