Bugfixes

• Fix a memory leak which would occur any time loki.process had its configuration reloaded. (@​ptodev)

  and if you use this exact function in your config, then you will need to rename your module. (@​wildum)

Features

• A new otelcol.exporter.debug component for printing OTel telemetry from
  other otelcol components to the console. (@​BarunKGP)

Bugfixes

• Fix an issue which caused the config to be reloaded if a config reload was triggered but the config hasn't changed.
  The bug only affected the "metrics" and "logs" subsystems in Static mode. (@​ptodev)

v0.39.0

Compare Source

Breaking changes

• otelcol.receiver.prometheus will drop all otel_scope_info metrics when converting them to OTLP. (@​wildum)

  • If the otel_scope_info metric has labels otel_scope_name and otel_scope_version,
    their values will be used to set OTLP Instrumentation Scope name and version respectively.
  • Labels of otel_scope_info metrics other than otel_scope_name and otel_scope_version
    are added as scope attributes with the matching name and version.

  argument instead of a block label. (@​hainenber)

• In the azure exporter, dimension options will no longer be validated by the Azure API. (@​kgeckhart)

  • This change will not break any existing configurations and you can opt in to validation via the validate_dimensions configuration option.
  • Before this change, pulling metrics for azure resources with variable dimensions required one configuration per metric + dimension combination to avoid an error.
  • After this change, you can include all metrics and dimensions in a single configuration and the Azure APIs will only return dimensions which are valid for the various metrics.

• In Static mode's traces subsystem, spanmetrics used to be generated prior to load balancing.
  This could lead to inaccurate metrics. This issue only affects Agents using both spanmetrics and
  load_balancing, when running in a load balanced cluster with more than one Agent instance. (@​ptodev)

  allowing invalid combination of configuration options. (@​thampiotr)

• Fixed issue where adding a module after initial start, that failed to load then subsequently resolving the issue would cause the module to
  permanently fail to load with id already exists error. (@​mattdurham)

• Allow the usage of encodings other than UTF8 to be used with environment variable expansion. (@​mattdurham)

• Fixed an issue where native histogram time series were being dropped silently. (@​krajorama)

• Static mode's spanmetrics processor will now prune histograms when the dimension cache is pruned.
  Dimension cache was always pruned but histograms were not being pruned. This caused metric series
