After sandbox and your application have been started the next thing is to look at the collected data. The sandbox environment provides two ways to explore the data: Grafana for metrics/event metrics and Kibana for events. Yes, it is also possible to look at individual metric records with Kibana, but since they make more sense when added together Grafana is a better option for metrics exploration.


The sandbox version of Grafana is started on port 3000. The administrative user/password combination is admin/admin.

The Grafana version that is packaged in the sandbox environment comes with these dashboards:

  • Actor Events
  • Actor Metrics
  • Dispatcher Metrics
  • HTTP Client Metrics
  • HTTP Endpoint Metrics
  • HTTP Server Metrics
  • JVM Metrics
  • Node Metrics
  • Remote Actor Metrics
  • Router Metrics
  • Stopwatch Metrics

For more information about the Grafana dashboards please see the details section in the visualization docs.


The sandbox version of Kibana is started on port 5601.

Create index

Before you can start exploring data in Kibana you must set up an index. Click on Settings and Indices: Kibana settings

Check the box Index contains time-based events and thereafter create the index:

  • cinnamon-events

Kibana index

Explore data

To explore the data in Kibana you click on the Discover tab and select a specific index, e.g. cinnamon-events:

Kibana index

Check the Kibana documentation for more information about how to use the discoverability.

Other indices

Elasticsearch is used as a datasource for all data in the sandbox. This means that metric related data is stored there too. Although, Grafana is the primary source for exploring metric data it is also possible to get to individual metric data in Kibana. All metric data is stored in the index cinnamon-metrics-YYYY-MM, where YYYY is the current year and MM is the number of the current month.

Lightbend Telemetry and ConductR Sandbox

This concludes the setup and use of the sandbox environment. Remember that the sandbox is not intended for production use. If you want to run Lightbend Telemetry in a production environment you should keep on reading the documentation.
