Currently no performance, trace and exception data can be shown in the UI.
**Edit 17:16**: The inavailabilty of the Elasticsearch cluster was just 10 minutes in the end. One of the nodes in the cluster shared its host machine with a virtual machine under heavy load and dragged the cluster performance down. In case this happens again we will shutdown the node the next time so that a smaller cluster with healthy nodes can keep up with our Elasticsearch performance requirements.
