0.17.0

Overview

This release introduces a single entrypoint to setup the module: metrics.cfg, as well as several updates due to package embedding to the core Tarantool (available only in master now).

Breaking changes

This release should not break existing behavior.

Added

• metrics.cfg{} -- a single entrypoint to setup the module:
  • include and exclude options with the same effect as in enable_default_metrics(include, exclude) (but its deprecated features already disabled);
  • labels options with the same effect as set_global_labels(labels);
  • values and effect (like default metrics callbacks) are preserved between reloads;
  • does not deal with external features like cartridge HTTP setup
• Versioning support through require('metrics')._VERSION

Changed

• Setup cartridge hotreload inside the role
• Extend enable_default_metrics() API:
  • 'all' and 'none' options for include argument,
  • simultaneous include and exclude arguments (exclude has higher priority)
• Build rock with cmake
• Override built-in metrics, if installed

Deprecated

• Passing nonexistent metrics to enable_default_metrics()
• Using {} as include in enable_default_metrics() to enable all metrics
• Versioning support through require('metrics').VERSION
