Upgrading

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

Notable changes:

Breaking changes

• (Experimental) In prometheus.write.queue changed parallelism from attribute to a block to allow for dynamic scaling. (@mattdurham)

• Remove tls_basic_auth_config_path attribute from prometheus.exporter.mongodb configuration as it does not configure TLS client behavior as previously documented.

• Remove encoding and encoding_file_ext from otelcol.exporter.awss3 component as it was not wired in to the otel component and Alloy does not currently integrate the upstream encoding extensions that this would utilize.

Features

• Add a otelcol.receiver.tcplog component to receive OpenTelemetry logs over a TCP connection. (@nosammai)

• (Public preview) Add otelcol.receiver.filelog component to read otel log entries from files (@dehaansa)

• (Public preview) Add a otelcol.processor.cumulativetodelta component to convert metrics from
  cumulative temporality to delta. (@madaraszg-tulip)

• (Experimental) Add a stage.windowsevent block in the loki.process component. This aims to replace the existing stage.eventlogmessage. (@wildum)

• Add pyroscope.relabel component to modify or filter profiles using Prometheus relabeling rules. (@marcsanmi)

• (Experimental) A new foreach block which starts an Alloy pipeline for each item inside a list. (@wildum, @thampiotr, @ptodev)

• Fix an issue where Prometheus metric name validation scheme was set by default to UTF-8. It is now set back to the previous "legacy" scheme. An experimental flag --feature.prometheus.metric-validation-scheme can be used to switch it to utf-8 to experiment with UTF-8 support.
