v1.7.0-rc.1

This is release v1.7.0-rc.1 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)

• For sharding targets during clustering, loki.source.podlogs now only takes into account some labels. (@ptodev)

Bugfixes

• Fixed an issue in the pyroscope.write component to prevent TLS connection churn to Pyroscope when the pyroscope.receive_http clients don't request keepalive (@madaraszg-tulip)

• Fixed an issue in the pyroscope.write component with multiple endpoints not working correctly for forwarding profiles from pyroscope.receive_http (@madaraszg-tulip)

• Fixed a few race conditions that could lead to a deadlock when using import statements, which could lead to a memory leak on /metrics endpoint of an Alloy instance. (@thampiotr)

• Fix a race condition where the ui service was dependent on starting after the remotecfg service, which is not guaranteed. (@dehaansa & @erikbaranowski)

• Fixed an issue in the otelcol.exporter.prometheus component that would set series value incorrectly for stale metrics (@YusifAghalar)

• loki.source.podlogs: Fixed a bug which prevented clustering from working and caused duplicate logs to be sent.
  The bug only happened when no selector or namespace_selector blocks were specified in the Alloy configuration. (@ptodev)

• Fixed an issue in the pyroscope.write component to allow slashes in application names in the same way it is done in the Pyroscope push API (@marcsanmi)

• Fixed a crash when updating the configuration of remote.http. (@kinolaev)

• Fixed an issue in the otelcol.processor.attribute component where the actions delete and hash could not be used with the pattern argument. (@wildum)
