I have a problem with Marvel. I installed it on the same machine than Elasticsearch, Logstash and Kibana. I have a single instance of Elasticsearch running and the node is both master and data. But I have this message: "Waiting for Marvel Data. It appears that we have not received any data for this cluster. Marvel data is sent every 10 seconds by the agent plugin; once the data appears this page will automatically redirect to the overview page." when I access to the marvel pannel. Reading the previous posts, I understood that the marvel access was granted once the master node had shown up and I don't understand what's wrong with my set up.
Thanks in adavance for your help,
