Exporting Dropwizard metrics over to Graphite
In the early recipes of this chapter, we learned how to create metrics using Dropwizard's Codahale library. Later, we learned how to start Graphite using Docker and understood the basics of using the Graphite interface. In this recipe, we will be exporting the metrics we created in the geolocation application over to this Graphite instance, which will then be used by Grafana for graphing.
Getting ready
As we will be working on the geolocation application, follow these steps:
Open the STS IDE.
Navigate to the
geolocationproject, and get ready for the next step.Start Graphite if you haven't done so. You can use the
docker-compose-graphite.ymlfile that we created earlier to start Graphite.
How to do it...
The geolocation application currently exposes two metrics using the Codahale MetricRegistry: geolocationWriteRequestCount and geolocationLastWriteTime. There were two methods we used to view these metrics: using Spring's /metrics endpoint and using...
