After developer sandbox and your application have been started the next thing is to look at the collected data. The developer 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 developer sandbox version of Grafana is started on http://localhost:3000.
First log in to Grafana. The default user/password is
Then enable the Cinnamon Elasticsearch App, which is automatically installed. There’s a link on the Grafana homepage:
Enable the plugin using the default Elasticsearch location:
You can then view the dashboards, which will begin displaying data from your application:
The Cinnamon Elasticsearch plugin contains these dashboards:
- Akka Actors
- Akka Dispatchers
- Akka Events
- Akka HTTP Clients
- Akka HTTP Endpoints
- Akka HTTP Servers
- Akka Remote Actors
- Akka Remote Nodes
- Akka Routers
- JVM Metrics
- Stopwatch Metrics
For more information about the Grafana dashboards please see the details section in the visualization docs.
The developer sandbox version of Kibana is started on http://localhost:5601.
First log in to Kibana. The default user/password is
Before you can start exploring data in Kibana, you must set up an index. The
Index Patterns page should be the default page after logging in, when there are no indices already defined. You can navigate to this page by selecting
cinnamon-events for the
Index pattern and then
Create the index:
To explore the data in Kibana you click on the
Discover tab and select a specific index, e.g.
Check the Kibana documentation for more information about how to use the discoverability.
Elasticsearch is used as a datasource for all data in the developer 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
YYYY is the current year and
MM is the number of the current month.
This concludes the setup and use of the developer sandbox environment. Remember that the developer 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.
