Upgrading

Read the release notes for specific instructions on upgrading from older versions:

Notable changes:

Breaking changes

• Removed open_port and executable_name from top level configuration of Beyla component. Removed enabled argument from network block. (@marctc)

• Breaking changes from the OpenTelemetry Collector v0.122 update: (@wildum)

  • otelcol.exporter.splunkhec: min_size_items and max_size_items were replaced by min_size, max_size and sizer in the batcher block to allow
    users to configure the size of the batch in a more flexible way.
  • The telemetry level of Otel components is no longer configurable. The level argument in the debug_metrics block is kept to avoid breaking changes but it is not used anymore.
  • otelcol.processor.tailsampling changed the unit of the decision timer metric from microseconds to milliseconds. (change unit of otelcol_processor_tail_sampling_sampling_decision_timer_latency)
  • otelcol.processor.deltatocumulative: rename otelcol_deltatocumulative_datapoints_processed to otelcol_deltatocumulative_datapoints and remove the metrics otelcol_deltatocumulative_streams_evicted, otelcol_deltatocumulative_datapoints_dropped and otelcol_deltatocumulative_gaps_length.
  • The regex attribute was removed from otelcol.processor.k8sattributes. The extract-patterns function from otelcol.processor.transform can be used instead.
  • The default value of metrics_flush_interval in otelcol.connector.servicegraph was changed from 0s to 60s.
  • s3_partition in otelcol.exporter.awss3 was replaced by s3_partition_format.

• (Experimental) prometheus.write.queue metric names changed to align better with prometheus standards. (@mattdurham)

Features

• Add otelcol.receiver.awscloudwatch component to receive logs from AWS CloudWatch and forward them to other otelcol.* components. (@wildum)
• Add loki.enrich component to enrich logs using labels from discovery.* components. (@v-zhuravlev)
• Add string concatenation for secrets type (@ravishankar15)
• Add support for environment variables to OpenTelemetry Collector config. (@jharvey10)
• Replace graph in Alloy UI with a new version that supports modules and data flow visualization. (@wildum)
• Added --cluster.wait-for-size and --cluster.wait-timeout flags which allow to specify the minimum cluster size
  required before components that use clustering begin processing traffic to ensure adequate cluster capacity is
  available. (@thampiotr)
• Add trace_printer to beyla.ebpf component to print trace information in a specific format. (@marctc)
• Add support for live debugging and graph in the UI for components imported via remotecfg. (@wildum)
