To use Marvel, you need to install two components:
- An Elasticsearch plugin that collects data from each node in your cluster. This plugin must be installed on every node.
- A Kibana app that provides the Marvel monitoring UI.
By default, the Marvel plugin stores data in the same Elasticsearch cluster where it is installed. If you are monitoring a production cluster we recommend that you store the Marvel data in a separate monitoring cluster. Sending the Marvel data to a monitoring cluster helps ensure that you can continue to monitor your production cluster if it’s in an unhealthy state.
