End User Changelog

🛑 Breaking changes 🛑

• receiver/sqlserver: Standardizing the unit interpretation of lookback_time in config for top query collection (#43573)
  Like other interval related config values, lookback_time also should suffix 's' to represent time in seconds.

💡 Enhancements 💡

• connector/count: Support for setting attributes from scope and resource levels. Precedence order: Span (or Log Record, etc.) > Scope attributes > Resource attributes. (#41859)

• connector/spanmetrics: Add add_resource_attributes opt-in config option to keep resource attributes in generated metrics (#43394)
  This configuration option allows users to override the connector.spanmetrics.excludeResourceMetrics feature gate
  and restore the old behavior of including resource attributes in metrics. This is needed for customers whose
  existing dashboards depend on resource attributes being present in the generated metrics.

• exporter/azuremonitor: Add authenticator extension support to the Azure Monitor exporter. (#41004)

• exporter/azuremonitor: Updated azure monitor exporter to use OTEL semantic conventions 1.34.0 (#41289)

  The default values now match exactly the default in batch processor.

• exporter/elasticsearch: Update Elasticsearch exporter ECS mapping mode encoder semantic convention mappings (#43805)

• exporter/googlecloudstorage: Implement skeleton of googlecloudstorage exporter. (#43123)

  The AWS Logs Encoding Extension now supports unmarshaling AWS Network Firewall logs into OpenTelemetry logs format.

• pkg/ottl: Support taking match patterns from runtime data in the replace_all_patterns and replace_pattern functions. (#43555)

• pkg/ottl: Add TrimPrefix and TrimSuffix to OTTL (#43883)
  This is a much optimal way to remove prefix/suffix compare with replace_pattern(name, "^prefixed", "")

• pkg/ottl: Added support for dynamic delimiter in Split() function in OTTL. (#43555)

• pkg/ottl: Added support for dynamic delimiter in Concat() function in OTTL. (#43555)

• pkg/ottl: Added support for dynamic prefix/suffix in HasPrefix and HasSuffix functions in OTTL. (#43555)

• pkg/ottl: Remove unnecessary regexp compilation every execution (#43915)

• pkg/ottl: Add unit and type subpaths for profile.sample_type and profile.period_type. (#43723)

• pkg/ottl: Support taking match patterns from runtime data in the replace_all_matches and replace_match functions. (#43555)

• pkg/ottl: Support taking match patterns from runtime data in the IsMatch function. (#43555)

• pkg/ottl: Remove unnecessary full copy of maps/slices when setting value on sub-map (#43949)

• pkg/ottl: Add XXH128 Converter function to converts a value to a XXH128 hash/digest (#42792)

• pkg/ottl: Support dynamic keys in the delete_key and delete_matching_keys functions, allowing the key to be specified at runtime. (#43081)

• pkg/ottl: Support paths and expressions as keys in keep_keys and keep_matching_keys (#43555)

• pkg/ottl: Support dynamic pattern keys in ExtractPatterns and ExtractGrokPatterns functions, allowing the keys to be specified at runtime. (#43555)

• pkg/ottl: Added support for dynamic encoding in Decode() function in OTTL. (#43555)

• processor/filter: Allow setting OTTL conditions to filter out whole resources (#43968)
  If any conditions set under the resource key for any signals match, the resource is dropped.

• processor/k8sattributes: Support extracting deployment name purely from the owner reference (#42530)

• processor/metricstarttime: Graduate the metricstarttimeprocessor to beta. (#43656)

• processor/redaction: Extend database query obfuscation to span names. Previously, database query obfuscation (SQL, Redis, MongoDB) was only applied to span attributes and log bodies. Now it also redacts sensitive data in span names. (#43778)

• processor/resourcedetection: Add the dt.smartscape.host resource attribute to data enriched with the Dynatrace detector (#43650)

• receiver/azureeventhub: Adds support for receiving Azure app metrics from Azure Event Hubs in the azureeventhubreceiver (#41343, #41367)
  The azureeventhubreceiver now supports receiving custom metrics emitted by applications to Azure Insights and forwarded using Diagnostic Settings to Azure Event Hub.
  There's also on optional setting to aggregate received metrics into a single metric to keep the original name, instead of multiply the metrics by added suffixes _total, _sum, _max etc.

• receiver/ciscoosreceiver: ciscoosreceiver: Add new receiver for collecting metrics from Cisco network devices via SSH (#42647)
  Supports Cisco IOS, IOS-XE, and NX-OS devices with SSH-based metric collection.
  Initial implementation includes system scraper for device availability and connection metrics.

• receiver/ciscoosreceiver: ciscoosreceiver: Add new receiver for collecting metrics from Cisco network devices via SSH (#42647)
  Supports Cisco IOS, IOS-XE, and NX-OS devices with SSH-based metric collection.
  Initial implementation includes system scraper for device availability and connection metrics.

• receiver/gitlab: Promote GitLab receiver to Alpha stability (#41592)

• receiver/jmx: Add JMX scraper version 1.51.0-alpha (#43667)

• receiver/pprof: convert google/pprof to OTel profiles (#42843)

🧰 Bug fixes 🧰

• exporter/clickhouse: Fix a bug in the exporter factory resulting in a nil dereference panic when the clickhouse.json feature gate is enabled (#43733)

• exporter/kafka: franz-go: Fix underreported kafka_exporter_write_latency metric (#43803)

• exporter/loadbalancing: Fix high cardinality issue in loadbalancing exporter by moving endpoint from exporter ID to attributes (#43719)
  Previously, the exporter created unique IDs for each backend endpoint by appending the endpoint
  to the exporter ID (e.g., loadbalancing_10.11.68.62:4317). This caused high cardinality in metrics,
  especially in dynamic environments. Now the endpoint is added as an attribute instead.

• exporter/pulsar: Fix the oauth2 flow for pulsar exporter by adding additional configuration fields (#435960)
  Fixes the oauth2 authentication flow in pulsar exporter by exposing additional configuration like private_key and scope.

• processor/metricstarttime: Do not set start timestamp if it is already set. (#43739)

• processor/tail_sampling: Fix panic when invalid regex was sent to string_attribute sampler (#43735)

• receiver/awss3: Fix S3 prefix trimming logic in awss3reader to correctly handle empty, single slash '/', and double slash '//' prefixes. (#43587)
  This fix ensures the S3 object prefix is generated consistently for all prefix formats (e.g., "", /, //, /logs/, //raw//),
  preventing malformed S3 paths when reading from buckets with non-standard prefixes.

• receiver/hostmetrics: Allow process metrics to be recorded if the host does not have cgroup functionality (#43640)

• receiver/kafka: Corrected the documentation for the Kafka receiver to accurately the supported/default group balancer strategies. (#43892)

• receiver/postgresql: Change the unit of the metric postgresql.table.vacuum.count to be vacuum instead of vacuums (#43272)

• receiver/prometheus: Fix missing staleness tracking leading to missing no recorded value data points. (#43893)

• receiver/prometheusremotewrite: Fixed a concurrency bug in the Prometheus remote write receiver where concurrent requests with identical job/instance labels would return empty responses after the first successful request. (#42159)

• receiver/pulsar: Fix the oauth2 flow for pulsar exporter by adding additional configuration fields (#435960)
  Fixes the oauth2 authentication flow in pulsar receiver by exposing additional configuration like private_key and scope.

• receiver/receiver_creator: Fix annotation-discovery config unmarshaling for nested configs (#43730)
