This is release v1.9.2 of Grafana Alloy.

Upgrading

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

Notable changes:

Bugfixes

• Send profiles concurrently from pyroscope.ebpf. (@korniltsev)

• Fix the validate command not understanding the livedebugging block. (@dehaansa)

• Fix invalid class names in python profiles obtained with pyroscope.ebpf. (@korniltsev)

• Fixed a bug which prevented non-secret optional secrets to be passed in as number arguments. (@ptodev)

• For CRD-based components (prometheus.operator.*), retry initializing informers if the apiserver request fails. This rectifies issues where the apiserver is not reachable immediately after node restart. (@dehaansa)

Other changes

• Add no-op blocks and attributes to the prometheus.exporter.windows component (@ptodev).
  Version 1.9.0 of Alloy removed the msmq block, as well as the enable_v2_collector, where_clause, and use_api attributes in the service block.
  This made it difficult for users to upgrade, so those attributes have now been made a no-op instead of being removed.

Installation

Refer to our installation guide for how to install Grafana Alloy.

This is release v1.9.1 of Grafana Alloy.

Upgrading

Notable changes:

Bugfixes

• Update the prometheus.exporter.windows component to version v0.30.7. This fixes an error with the exchange collector and terminal_services collector (@dehaansa)

• Fix loki.source.firehose to propagate specific cloudwatch event timestamps when useIncomingTs is set to true. (@michaelPotter)

Upgrading

Notable changes:

Breaking changes

• The prometheus.exporter.windows component has been update to version v0.30.6. This update includes a significant rework of the exporter and includes some breaking changes. (@dehaansa)

  • The msmq and service collectors can no longer be configured with a WMI where clause. Any filtering previously done in a where clause will need to be done in a prometheus.relabel component.
  • The service collector no longer provides enable_v2_collector and use_api configuration options.
  • The mscluster_* and netframework_* collectors are now replaced with one mscluster and netframework collector that allows you to enable the separate metric groupings individually.
  • The teradici_pcoip and vmware_blast collectors have been removed from the exporter.

• The prometheus.exporter.oracledb component now embeds the oracledb_exporter from oracle instead of the deprecated oracledb_exporter from iamseth for collecting metrics from an OracleDB server: (@wildum)

  • The arguments username, password, default_metrics, and custom_metrics are now supported.
  • The previously undocumented argument custom_metrics is now expecting a list of paths to custom metrics files.
  • The following metrics are no longer available by default: oracledb_sessions_activity, oracledb_tablespace_free_bytes

• (Experimental) The enable_context_propagation argument in beyla.ebpf has been replaced with the context_propagation argument.
  Set enable_context_propagation to all to get the same behaviour as enable_context_propagation being set to true.

Features

• Bump snmp_exporter and embedded modules in prometheus.exporter.snmp to v0.29.0, add cisco_device module support (@v-zhuravlev)

• Add the otelcol.storage.file extension to support persistent sending queues and otelcol.receiver.filelog file state tracking between restarts. (@dehaansa)

• Add otelcol.exporter.googlecloud community component to export metrics, traces, and logs to Google Cloud. (@motoki317)

• Add support to configure basic authentication for alloy http server. (@kalleep)

• Add validate command to alloy that will perform limited validation of alloy configuration files. (@kalleep)

• Add support to validate foreach block when using validate command. (@kalleep)

• Add otelcol.receiver.splunkhec component to receive events in splunk hec format and forward them to other otelcol.* components. (@kalleep)

• Add support for Mimir federated rule groups in mimir.rules.kubernetes (@QuentinBisson)

Upgrading

Notable changes:

Breaking changes

• Removed open_port and executable_name from top level configuration of Beyla component. Removed enabled argument from network block. (@marctc)

• Breaking changes from the OpenTelemetry Collector v0.122 update: (@wildum)

  • otelcol.exporter.splunkhec: min_size_items and max_size_items were replaced by min_size, max_size and sizer in the batcher block to allow
    users to configure the size of the batch in a more flexible way.
  • The telemetry level of Otel components is no longer configurable. The level argument in the debug_metrics block is kept to avoid breaking changes but it is not used anymore.
  • otelcol.processor.tailsampling changed the unit of the decision timer metric from microseconds to milliseconds. (change unit of otelcol_processor_tail_sampling_sampling_decision_timer_latency)
  • otelcol.processor.deltatocumulative: rename otelcol_deltatocumulative_datapoints_processed to otelcol_deltatocumulative_datapoints and remove the metrics otelcol_deltatocumulative_streams_evicted, otelcol_deltatocumulative_datapoints_dropped and otelcol_deltatocumulative_gaps_length.
  • The regex attribute was removed from otelcol.processor.k8sattributes. The extract-patterns function from otelcol.processor.transform can be used instead.
  • The default value of metrics_flush_interval in otelcol.connector.servicegraph was changed from 0s to 60s.
  • s3_partition in otelcol.exporter.awss3 was replaced by s3_partition_format.

• (Experimental) prometheus.write.queue metric names changed to align better with prometheus standards. (@mattdurham)

  required before components that use clustering begin processing traffic to ensure adequate cluster capacity is
  available. (@thampiotr)
• Add trace_printer to beyla.ebpf component to print trace information in a specific format. (@marctc)
