signalfx/splunk-otel-collector v0.130.0

on GitHub

This Splunk OpenTelemetry Collector release includes changes from the opentelemetry-collector v0.130.0
and the opentelemetry-collector-contrib v0.130.0 releases where appropriate.

🛑 Breaking changes 🛑

• (Core) exporter/otlp: Remove deprecated batcher config from OTLP, use queuebatch (#13339)
• (Contrib) kubeletstats: Move receiver.kubeletstats.enableCPUUsageMetrics feature gate to stable (#39650)
• (Contrib) kafka: The default client ID for Kafka components now honours configuration, and defaults to "otel-collector". (#41090)
  The client ID configuration was ineffective, and (when using the Sarama implementation)
  always defaulted to "sarama". We now honour the configuration, and the default has changed,
  hence this is a breaking change for anyone relying on the client ID being "sarama".

🚩 Deprecations 🚩

• (Contrib) splunkhecexporter: Deprecate 'batcher' config, use 'sending_queue::batch' instead (#41224)
• (Contrib) spanmetricsconnector: Mark dimensions_cache_size as deprecated following the upstream guidelines (#41101)

💡 Enhancements 💡

• (Splunk) Update jmx-metric-gatherer version to v1.47.0 (#6399)
• (Splunk) Update bundled openjdk version to 11.0.28_6 (#6459)
• (Splunk) receiver/discovery: Reduce amount of attributes sent with the entities to the required set (#6419)
• (Splunk) receiver/discovery: Use app.kubernetes.io/instance pod label for service.name entity attribute value if available (#6435)
• (Contrib) loadbalancingexporter: Use a linear probe to decrease variance caused by hash collisions, which was causing a non-uniform distribution of loadbalancing. (#41200)
• (Contrib) mysqlreceiver: Collect 'fsync' log operations. (#41175)
• (Contrib) mysqlreceiver: Add mysql.max_used_connections metric (#40626)
  mysql.max_used_connections contains the maximum number of used sessions since the instance start.
• (Contrib) sqlserverreceiver: Adding 'sqlserver.cpu.count' metric (#41032)
• (Contrib) postgresqlreceiver: Only scrape the query samples that are newer than last scraped (#40622)
• (Contrib) pkg/ottl: Add new Keys converter to extract all keys from a given map. (#39256)
• (Contrib) pkg/ottl: Added a new ParseInt OTTL Function. (#40758)
• (Contrib) receiver/postgresql: Move receiver.postgresql.connectionPool feature gate to alpha (#30831)
  This change updates the receiver to use the connection pooling for performance benefits.
• (Contrib) transformprocessor: Add profiles support to transformprocessor. (#39009)
• (Core) exporterhelper: Enable items and bytes sizers for persistent queue (#12881)
• (Core) exporterhelper: Refactor persistent storage size backup to always record it. (#12890)
• (Core) exporterhelper: Add support to configure a different Sizer for the batcher than the queue (#13313)
• (Contrib) receiver/sqlserver Make queries compatible with Azure SQL Database (#41102)

🧰 Bug fixes 🧰

• (Splunk) receiver/discovery: Fix disabling observers with properties (#6437)
• (Contrib) kafkareceiver (franz-go client): Fix race on lost partition (#41239)
  When using the franz-go client, fixes an edge case where a consumer could
  lose a partition while it is consuming messages. This leads to unexpected
  behavior due to the race and likely cause the consumer to malfunction.
• (Contrib) receivercreator: Fix incorrect traces consumer filtering in filterConsumerSignals function (#41033)
  The bug caused traces consumers to be incorrectly filtered when metrics were disabled.
• (Contrib) pkg/ottl: Fix OTTL functions by using setters. (#39100)
• (Contrib) receiver/prometheusreceiver: Fixes masking of authentication credentials in Prometheus receiver, when reloading the Prometheus config. (#40520, #40916)
• (Contrib) kafkametricsreceiver: Fix aws_msk configuration in the doc (#41118)
• (Contrib) filelogreceiver: Fix remove, copy, and move operator configuration validation. (#40728)
  Previously, the receiver would allow configurations that were guaranteed to cause a Collector panic. The Collector will now fail to start with friendly error messages.
• (Contrib) pkg/ottl: Fix an issue where the attribute values were amended in the profiles dictionary. (#40738)
• (Contrib) pkg/ottl: Fixes the OTTL nanoseconds formatter to correctly handle 9 digits of nanoseconds, ensuring accurate time formatting and parsing. (#41144)
  Places that import "github.com/open-telemetry/opentelemetry-collector-contrib/internal/coreinternal/timeutils" are likely affected by this change. For example, FormatTimeand Time OTTL functions are affected. See here for a full list of affected functionalities.
• (Contrib) sqlserverreceiver: Fix incorrect configuration used in query sample collection. It was intended to retrieve the maximum number of rows per query from config.MaxRowsPerQuery, but it was mistakenly using config.TopQueryCount instead.
  (#40943)
• (Core) exporterhelper: Fix exporter.PersistRequestContext feature gate (#13342)
• (Core) exporterhelper: Preserve all metrics metadata when batch splitting. (#13236)
  Previously, when large batches of metrics were processed, the splitting logic in metric_batch.go could
  cause the name field of some metrics to disappear. This fix ensures that all metric fields are
  properly preserved when metricRequest objects are split.
• (Core) service: Default internal metrics config now enables otel_scope_ labels (#12939, #13344)
  By default, the Collector exports its internal metrics using a Prometheus
  exporter from the opentelemetry-go repository. With this change, the Collector
  no longer sets "without_scope_info" to true in its configuration.
  This means that all exported metrics will have otel_scope_name,
  otel_scope_schema_url, and otel_scope_version labels corresponding to the
  instrumentation scope metadata for that metric.
  This notably prevents an error when multiple metrics are only distinguished
  by their instrumentation scopes and end up aliased during export.
  If this is not desired behavior, a Prometheus exporter can be explicitly
  configured with this option enabled.
