v1.11.0

Compare Source

Breaking changes

• Prometheus dependency had a major version upgrade from v2.55.1 to v3.4.2. (@​thampiotr)

  • The . pattern in regular expressions in PromQL matches newline characters now. With this change a regular expressions like .* matches strings that include \n. This applies to matchers in queries and relabel configs in Prometheus and Loki components.

  • The enable_http2 in prometheus.remote_write component's endpoints has been changed to false by default. Previously, in Prometheus v2 the remote write http client would default to use http2. In order to parallelize multiple remote write queues across multiple sockets its preferable to not default to http2. If you prefer to use http2 for remote write you must now set enable_http2 to true in your prometheus.remote_write endpoints configuration section.

  • The experimental CLI flag --feature.prometheus.metric-validation-scheme has been deprecated and has no effect. You can configure the metric validation scheme individually for each prometheus.scrape component.

  • Log message format has changed for some of the prometheus.* components as part of the upgrade to Prometheus v3.

  • The values of the le label of classic histograms and the quantile label of summaries are now normalized upon ingestion. In previous Alloy versions, that used Prometheus v2, the value of these labels depended on the scrape protocol (protobuf vs text format) in some situations. This led to label values changing based on the scrape protocol. E.g. a metric exposed as my_classic_hist{le="1"} would be ingested as my_classic_hist{le="1"} via the text format, but as my_classic_hist{le="1.0"} via protobuf. This changed the identity of the metric and caused problems when querying the metric. In current Alloy release, which uses Prometheus v3, these label values will always be normalized to a float like representation. I.e. the above example will always result in my_classic_hist{le="1.0"} being ingested into Prometheus, no matter via which protocol. The effect of this change is that alerts, recording rules and dashboards that directly reference label values as whole numbers such as le="1" will stop working.

    The recommended way to deal with this change is to fix references to integer le and quantile label values, but otherwise do nothing and accept that some queries that span the transition time will produce inaccurate or unexpected results.

  See the upstream Prometheus v3 migration guide for more details.

• prometheus.exporter.windows dependency has been updated to v0.31.1. (@​dehaansa)

  • There are various renamed metrics and two removed collectors (cs, logon), see the v1.11 release notes for more information.

• scrape_native_histograms attribute for prometheus.scrape is now set to false, whereas in previous versions of Alloy it would default to true. This means that it is no longer enough to just configure scrape_protocols to start with PrometheusProto to scrape native histograms - scrape_native_histograms has to be enabled. If scrape_native_histograms is enabled, scrape_protocols will automatically be configured correctly for you to include PrometheusProto. If you configure it explicitly, Alloy will validate that PrometheusProto is in the scrape_protocols list.

• Add otel_attrs_to_hec_metadata configuration block to otelcol.exporter.splunkhec to match otelcol.receiver.splunkhec. (@​cgetzen)

• [otelcol.processor.batch] Two arguments have different default values. (@​ptodev)

  • send_batch_size is now set to 2000 by default. It used to be 8192.
  • send_batch_max_size is now set to 3000 by default. It used to be 0.
  • This helps prevent issues with ingestion of batches that are too large.

• OpenTelemetry Collector dependencies upgraded from v0.128.0 to v0.134.0. (@​ptodev)

  • The otelcol.receiver.opencensus component has been deprecated and will be removed in a future release, use otelcol.receiver.otelp instead.
  • [otelcol.exporter.*] The deprecated blocking argument in the sending_queue block has been removed.
    Use block_on_overflow instead.
  • [otelcol.receiver.kafka, otelcol.exporter.kafka]: Removed the broker_addr argument from the aws_msk block.
    Also removed the SASL/AWS_MSK_IAM authentication mechanism.
  • [otelcol.exporter.splunkhec] The batcher block is deprecated and will be removed in a future release. Use the queue block instead.
  • [otelcol.exporter.loadbalancing] Use a linear probe to decrease variance caused by hash collisions, which was causing a non-uniform distribution of loadbalancing.
  • [otelcol.connector.servicegraph] The database_name_attribute argument has been removed.
  • [otelcol.connector.spanmetrics] Adds a default maximum number of exemplars within the metric export interval.
  • [otelcol.processor.tail_sampling] Add a new block_on_overflow config attribute.

Features

• Add the otelcol.receiver.fluentforward receiver to receive logs via Fluent Forward Protocol. (@​rucciva)

• Add the prometheus.enrich component to enrich metrics using labels from discovery.* components. (@​ArkovKonstantin)

• Add the otelcol.receiver.awsecscontainermetrics receiver (from upstream OTEL contrib) to read AWS ECS task- and container-level resource usage metrics. (@​gregbrowndev)

• Add node_filter configuration block to loki.source.podlogs component to enable node-based filtering for pod discovery. When enabled, only pods running on the specified node will be discovered and monitored, significantly reducing API server load and network traffic in DaemonSet deployments. (@​QuentinBisson)

• (Experimental) Additions to experimental database_observability.mysql component:

  • query_sample collector now supports auto-enabling the necessary setup_consumers settings (@​cristiangreco)
  • query_sample collector is now compatible with mysql less than 8.0.28 (@​cristiangreco)

(@​korniltsev)

• pyroscope.write, pyroscope.receive_http components include trace_id in logs and propagate it downstream. (@​korniltsev)

• Improve logging in pyroscope.write component. (@​korniltsev)

• Add comprehensive latency metrics to pyroscope.write component with endpoint-specific tracking for both push and ingest operations. (@​korniltsev, @​claude)

• Fix ebpf profiler metrics pyroscope_ebpf_active_targets, pyroscope_ebpf_profiling_sessions_total, pyroscope_ebpf_profiling_sessions_failing_total not being updated. (luweglarz)

• Fix prometheus.operator.podmonitors so it now handle portNumber from PodMonitor CRD. (@​kalleep)

• Fix pyroscope.receive_http so it does not restart server if the server configuration has not changed. (@​korniltsev)

• Increase default connection limit in pyroscope.receive_http from 100 to 16k. (@​korniltsev)

• Fix issue in prometheus.remote_write's WAL which could allow it to hold an active series forever. (@​kgeckhart)

• Fix issue in static and promtail converter where metrics type was not properly handled. (@​kalleep)

• Fix prometheus.operator.* components to allow them to scrape correctly Prometheus Operator CRDs. (@​thomas-gouveia)

• Fix data race inloki.source.docker that could cause Alloy to panic. (@​kalleep)

• Fix race conditions in loki.source.syslog where it could deadlock or cause port bind errors during config reload or shutdown. (@​thampiotr)

• Fix prometheus.exporter.redis component so that it no longer ignores the MaxDistinctKeyGroups configuration option. If key group metrics are enabled, this will increase the cardinality of the generated metrics. (@​stegosaurus21)

• Fix loki.source.podlogs component to properly collect logs from Kubernetes Jobs and CronJobs. Previously, the component would fail to scrape logs from short-lived or terminated jobs due to race conditions between job completion and pod discovery. The fix includes:

  • Job-aware termination logic with extended grace periods (10-60 seconds) to ensure all logs are captured
  • Proper handling of pod deletion and race conditions between job completion and controller cleanup
  • Separation of concerns: shouldStopTailingContainer() handles standard Kubernetes restart policies for regular pods, while shouldStopTailingJobContainer() handles job-specific lifecycle with grace periods
  • Enhanced deduplication mechanisms to prevent duplicate log collection while ensuring comprehensive coverage
  • Comprehensive test coverage including unit tests and deduplication validation
    This resolves the issue where job logs were being missed, particularly for fast-completing jobs or jobs that terminated before discovery. (@​QuentinBisson)

• Fix loki.source.journal creation failing with an error when the journal file is not found. (@​thampiotr)

• Fix graph UI so it generates correct URLs for components in remotecfg modules. (@​patrickeasters)

• Fix panic in loki.write when component is shutting down and external_labels are configured. (@​kalleep)

• Fix excessive debug logs always being emitted by prometheus.exporter.mongodb. (@​kalleep)
