Release Notes for different Wavefront proxy versions.

This page gives an overview of important changes for the most recent Wavefront proxy releases.

Version 7.0

  • The Wavefront proxy listener port (2878) can now be used as a direct ingestion endpoint for all data (metrics, histograms, spans/span logs)
  • New preprocessor features:
    • conditional logic for rules with if parameter.
    • global and multi-port rules
    • interactive rules tester
  • New proxy installs use Java 11 runtime

Version 6.1

Version 5.7

Version 5.5

  • Proxy version 5.1 had an issue with brand new non-containerized installs due to incorrect default location for buffer files. This release fixes that problem.

Version 5.1

This version includes support for the following new functionality:

  • Support for span logs. Both proxy version 5.1 and Wavefront service version 2019.30 or later are required for span logs.
  • Delta counter aggregation at the proxy. Previously, only the service performed delta counter aggregation.
  • New add functionality when sending SourceTag or SourceDescription directly to the proxy.
  • Hot reload for proxy preprocessor rules. Proxy checks for changes to the file every 5 seconds, so proxy restart is no longer required.
  • Several bug fixes and improvements related to ingestion and tracing.

Version 4.38

  • Wavefront histogram support for log ingestion
  • Support HTTP payloads for raw log ingestion
  • Miscellaneous bug fixes

Version 4.36

  • Generate RED metrics from tracing spans.

Version 4.35

  • First class integration for Zipkin. Anyone using Zipkin can substitute a Wavefront proxy for the Zipkin HTTP collector to send data to Wavefront.
  • Fixes minor Jaeger integration issues.

Version 4.34

  • Support for trace sampling.

Version 4.33

  • First class integration for Jaeger. Anyone using Jaeger can point their agent to the Wavefront proxy instead of the Jaeger collector to send data to Wavefront.
