Distributed Tracing No Longer in Beta

For several releases, we’ve fine-tuned our distributed tracing functionality based on internal and customer feedback. The feature has exited Beta and is now considered General Availability.

The new Tracing Best Practices guidelines help you get optimal results.

Improved Wavefront Monitoring

This release includes some handy tools for monitoring your Wavefront instance.

Updates to Spy API

In earlier releases, you can use the spy API to examine metric points and IDs. With this release, you can also examine spans. Information about this API is now on a separate doc page.

New wftop Tool

Wavefront Top (wftop) is an open source interactive tool for examining the shape of the live metric ingestion data and for exploring which metric namespaces were used in the last X days.

New and Changed Functions

This release includes new histogram functions and other improvements including a complete set of string functions.

New Histogram Manipulation Functions

This release includes two functions for making histogram visualization easier:

  • The summary() function returns a summary of a histogram.
  • The alignedSummary() function returns an aligned summary of a histogram.

For both functions, we return the following information by default:

max, P999, P99, P90, P75, avg, median (P50), P25, and min

You can specify a list of percentiles instead.

Forecasting, String Manipulation, and New Parameter for at()

  • New forecasting function, nnforecast(), which uses hypothesis testing and neural networks for prediction. This function is used by the AI Genie forecasting UI.
  • New string functions.
  • For the at() function, new parameter lookbackDistance. When you call at(end) or at(now), we look back by 1 hour by default. You can now specify a time period instead.
