• Update jfr-parser dependency to v0.9.3 to fix jfr parsing issues in pyroscope.java. (@korniltsev)

• Fixed an issue where passing targets from some standard library functions was failing with target::ConvertFrom error. (@thampiotr)

• Fixed an issue where indexing targets as maps (e.g. target["foo"]) or objects (e.g. target.foo) or using them with
  certain standard library functions was resulting in expected object or array, got capsule error under some
  circumstances. This could also lead to foreach evaluation failed errors when using the foreach configuration
  block. (@thampiotr)

• Update prometheus.write.queue to reduce memory fragmentation and increase sent throughput. (@mattdurham)

• Fixed an issue where the otelcol.exporter.kafka component would not start if the encoding was specific to a signal type. (@wildum)

This is release v1.7.0 of Grafana Alloy.

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)
