[Unreleased]

[1.1.0] - 2024-05-17

Added

• metrics.cfg{} "all" metasection for array include and exclude (metrics.cfg{include={'all'}} can be used instead of metrics.cfg{include='all'}, metrics.cfg{exclude={'all'}} can be used instead of metrics.cfg{include='none'})

• tnt_election_leader_idle metric.

• Histogram now logs a warning if observe is called with cdata value.

Changed

• Inconsistent metrics descrtiptions for memtx metrics.

• New memory metrics:

  • tnt_memtx_tuples_data_total

  • tnt_memtx_tuples_data_garbage
  • tnt_memtx_index_total

• Using cdata values with histogram:observe.

[1.0.0] - 2023-05-22

Changed

• Don't export self replication status.

Removed

• cartridge.roles.metrics moved to cartridge-metrics-role repository (incompatible change).

[0.17.0] - 2023-03-23

Added

• metrics.cfg{} -- a single entrypoint to setup the module:

  • does not deal with external features like cartridge HTTP setup
• Versioning support through require('metrics')._VERSION

Changed

• Setup cartridge hotreload inside the role
