Compare Source

Breaking changes

  • otelcol.receiver.prometheus will drop all otel_scope_info metrics when converting them to OTLP. (@​wildum)

    • If the otel_scope_info metric has labels otel_scope_name and otel_scope_version, their values will be used to set OTLP Instrumentation Scope name and version respectively.
    • Labels of otel_scope_info metrics other than otel_scope_name and otel_scope_version are added as scope attributes with the matching name and version.

  • The target block in prometheus.exporter.blackbox requires a mandatory name argument instead of a block label. (@​hainenber)

  • In the azure exporter, dimension options will no longer be validated by the Azure API. (@​kgeckhart)

    • This change will not break any existing configurations and you can opt in to validation via the validate_dimensions configuration option.
    • Before this change, pulling metrics for azure resources with variable dimensions required one configuration per metric + dimension combination to avoid an error.
    • After this change, you can include all metrics and dimensions in a single configuration and the Azure APIs will only return dimensions which are valid for the various metrics.
Features

  • A new discovery.ovhcloud component for discovering scrape targets on OVHcloud. (@​ptodev)

  • Allow specifying additional containers to run. (@​juangom)

Enhancements

  • Flow Windows service: Support environment variables. (@​jkroepke)

  • Allow disabling collection of root Cgroup stats in prometheus.exporter.cadvisor (flow mode) and the cadvisor integration (static mode). (@​hainenber)

  • Grafana Agent on Windows now automatically restarts on failure. (@​hainenber)

  • Added metrics, alerts and dashboard visualisations to help diagnose issues with unhealthy components and components that take too long to evaluate. (@​thampiotr)

  • The http config block may now reference exports from any component. Previously, only remote.* and local.* components could be referenced without a circular dependency. (@​rfratto)

  • Add support for Basic Auth-secured connection with Elasticsearch cluster using prometheus.exporter.elasticsearch. (@​hainenber)

  • Add a resource_to_telemetry_conversion argument to otelcol.exporter.prometheus for converting resource attributes to Prometheus labels. (@​hainenber)

  • pyroscope.ebpf support python on arm64 platforms. (@​korniltsev)

  • otelcol.receiver.prometheus does not drop histograms without buckets anymore. (@​wildum)

  • Added exemplars support to otelcol.receiver.prometheus. (@​wildum)

  • mimir.rules.kubernetes may now retry its startup on failure. (@​hainenber)

  • Added links between compatible components in the documentation to make it easier to discover them. (@​thampiotr)

  • Allow defining HTTPClientConfig for discovery.ec2. (@​cmbrad)

  • The remote.http component can optionally define a request body. (@​tpaschalis)

  • Added support for loki.write to flush WAL on agent shutdown. (@​thepalbi)

  • Add support for integrations-next static to flow config conversion. (@​erikbaranowski)

  • Add support for passing extra arguments to the static converter such as -config.expand-env. (@​erikbaranowski)

  • Added 'country' mmdb-type to log pipeline-stage geoip. (@​superstes)

  • Azure exporter enhancements for flow and static mode, (@​kgeckhart)

    • Allows for pulling metrics at the Azure subscription level instead of resource by resource
    • Disable dimension validation by default to reduce the number of exporter instances needed for full dimension coverage

  • Add max_cache_size to prometheus.relabel to allow configurability instead of hard coded 100,000. (@​mattdurham)

  • Add support for http_sd_config within a scrape_config for prometheus to flow config conversion. (@​erikbaranowski)

  • discovery.lightsail now supports additional parameters for configuring HTTP client settings. (@​ptodev)

  • Add sample_age_limit to remote_write config to drop samples older than a specified duration. (@​marctc)

  • Handle paths in the Kubelet URL for discovery.kubelet. (@​petewall)

  • loki.source.docker now deduplicates targets which report the same container ID. (@​tpaschalis)

Bugfixes

  • Update pyroscope.ebpf to fix a logical bug causing to profile to many kthreads instead of regular processes https://github.com/grafana/pyroscope/pull/2778 (@​korniltsev)

  • Update pyroscope.ebpf to produce more optimal pprof profiles for python processes https://github.com/grafana/pyroscope/pull/2788 (@​korniltsev)

  • In Static mode's traces subsystem, spanmetrics used to be generated prior to load balancing. This could lead to inaccurate metrics. This issue only affects Agents using both spanmetrics and load_balancing, when running in a load balanced cluster with more than one Agent instance. (@​ptodev)

  • Fixes loki.source.docker a behavior that synced an incomplete list of targets to the tailer manager. (@​FerdinandvHagen)

  • Fixes otelcol.connector.servicegraph store ttl default value from 2ms to 2s. (@​rlankfo)

  • Add staleness tracking to labelstore to reduce memory usage. (@​mattdurham)

  • Fix issue where prometheus.exporter.kafka would crash when configuring sasl_password. (@​rfratto)

  • Fix performance issue where perf lib where clause was not being set, leading to timeouts in collecting metrics for windows_exporter. (@​mattdurham)

  • Fix nil panic when using the process collector with the windows exporter. (@​mattdurham)

Other changes

  • Bump github.com/IBM/sarama from v1.41.2 to v1.42.1

  • Attach unique Agent ID header to remote-write requests. (@​captncraig)

  • Update to v2.48.1 of github.com/prometheus/prometheus. Previously, a custom fork of v2.47.2 was used. The custom fork of v2.47.2 also contained prometheus#12729 and prometheus#12677.
