Upgrading

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

Notable changes:

Security fixes

• Add quotes to windows service path to prevent path interception attack. CVE-2024-8975 (@mattdurham)

Breaking changes

• Some debug metrics for otelcol components have changed. (@thampiotr)
  For example, otelcol.exporter.otlp's exporter_sent_spans_ratio_total metric is now otelcol_exporter_sent_spans_total.

• [otelcol.processor.transform] The functions convert_sum_to_gauge and convert_gauge_to_sum must now be used in the metric context rather than in the datapoint context.
  open-telemetry/opentelemetry-collector-contrib#34567 (@wildum)

• Upgrade Beyla from 1.7.0 to 1.8.2. A complete list of changes can be found on the Beyla releases page: https://github.com/grafana/beyla/releases. (@wildum)
  It contains a few breaking changes for the component beyla.ebpf:

  • renamed metric process.cpu.state to cpu.mode
  • renamed metric beyla_build_info to beyla_internal_build_info

Features

• Added Datadog Exporter community component, enabling exporting of otel-formatted Metrics and traces to Datadog. (@polyrain)
• (Experimental) Add an otelcol.processor.interval component to aggregate metrics and periodically
  forward the latest values to the next component in the pipeline.

Enhancements

• Clustering peer resolution through --cluster.join-addresses flag has been improved with more consistent behaviour, better error handling and added support for A/AAAA DNS records. If necessary, users can temporarily opt out of this new behaviour with the --cluster.use-discovery-v1, but this can only be used as a temporary measure, since this flag will be disabled in future releases. (@thampiotr)

• Added a new panel to Cluster Overview dashboard to show the number of peers seen by each instance in the cluster. This can help diagnose cluster split brain issues. (@thampiotr)

• Updated Snowflake exporter with performance improvements for larger environments.
  Also added a new panel to track deleted tables to the Snowflake mixin. (@Caleb-Hurshman)

• Add a otelcol.processor.groupbyattrs component to reassociate collected metrics that match specified attributes from opentelemetry. (@kehindesalaam)

• Update windows_exporter to v0.27.2. (@jkroepke)
  The smb.enabled_list and smb_client.enabled_list doesn't have any effect anymore. All sub-collectors are enabled by default.

Bugfixes

• Fix a bug where the scrape timeout for a Probe resource was not applied, overwriting the scrape interval instead. (@morremeyer, @stefanandres)

• Fix a bug where custom components don't always get updated when the config is modified in an imported directory. (@ante012)

• Fixed an issue where providing <hostname>:<port> in --cluster.join-addresses would only resolve with DNS to a single address, instead of using all the available records. (@thampiotr)

Other

• Update OTel from v0.105.0 vo v0.108.0: (@wildum)

v1.3.1

This is release v1.3.1 of Grafana Alloy.

Upgrading

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

Notable changes:

• Changed the cluster startup behaviour, reverting to the previous logic where a failure to resolve cluster join peers results in the node creating its own cluster. This is to facilitate the process of bootstrapping a new cluster following user feedback (@thampiotr)

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