grafana/alloy v1.4.0-rc.2 on GitHub

This is release v1.4.0-rc.2 of Grafana Alloy.

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

[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

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. (@ArthurSens)

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.

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)
