Wavefront Java SDKs automatically collect a suite of diagnostic metrics that allow you to monitor the performance of your WavefrontSender instance. These metrics are collected once every minute and are reported to Wavefront using your WavefrontSender instance. How you send data to Wavefront determines the metrics that are collected
If you are sending data to Wavefront via the Wavefront proxy using a WavefrontProxyClient instance, the following diagnostic metrics are reported:

SDK Description |
Java SDKs |
| OpenTracing SDK |
Implements the OpenTracing specification. Lets you define, collect, and report custom trace data from any part of your application code.
Automatically derives RED metrics from the reported spans. |
|
| Metrics SDK |
Implements a standard metrics library. Lets you define, collect, and report custom business metrics and histograms from any part of your application code. |
|
| Framework SDK |
Reports predefined traces, metrics, and histograms from the APIs of a supported app framework. Lets you get started quickly with minimal code changes. |
|
| Sender SDK |
Lets you send raw values to Wavefront for storage as metrics, histograms, or traces, e.g., to import CSV data into Wavefront.
