🛑 Breaking changes 🛑

  • sumologicexporter: change logs behavior (#31479)

    • set OTLP as default format
    • add support for OTLP format
    • do not support metadata attributes
    • do not support source headers

  • sumologicexporter: change metrics behavior (#31479)

    • remove suppport for carbon2 and graphite
    • add support for otlp format
    • do not support metadata attributes
    • do not support source headers
    • set otlp as default metrics format

  • sumologicexporter: remove deprecated configuration options (#32315)
    migration has been described in the following document
    https://github.com/open-telemetry/opentelemetry-collector-contrib/tree/v0.100.0/exporter/sumologicexporter#migration-to-new-architecture

  • remotetapprocessor: Make the limit configuration work properly. (#32385)
    The limit configuration was ignored previously, but now it works according to the configuration and documentation.
    Nothing is required of users.
    See the remotetapprocessor's README.md for details.

  • groupbytraceprocessor: Fix groupbytrace metrics contain duplicate prefix (#32698)

  • vcenterreceiver: Removes vcenter.cluster.name attribute from vcenter.datastore metrics (#32674)
    If there were multiple Clusters, Datastore metrics were being repeated under Resources differentiated with a
    vcenter.cluster.name resource attribute. In the same vein, if there were standalone Hosts, in addition to
    clusters the metrics would be repeated under a Resource without the vcenter.cluster.name attribute. Now there
    will only be a single set of metrics for one Datastore (as there should be, as Datastores don't belong to
    Clusters).

  • resourcedetectionprocessor: Move processor.resourcedetection.hostCPUModelAndFamilyAsString feature gate to stable. (#29025)

  • filelog, journald, tcp, udp, syslog, windowseventlog receivers: The internal logger has been changed from zap.SugaredLogger to zap.Logger. (#32177)
    This should not have any meaningful impact on most users but the logging format for some logs may have changed.

  • awsxrayexporter: change x-ray exporter's translator to make "." split annotation pass as-is (#32694, #31732)
    This change make below change to beta stage for feature gate 'exporter.xray.allowDot'，this change will let the change mention below enable by default | In the past, X-Ray doesn’t support “.”. So we have a translator in x-ray export to translates it to “_” before sending traces to X-Ray Service. | To match otel naming style, x-ray service team decide to change their service to support both "." type and "" type of naming. In this case the translator that translate "." to "" is no-longer needed. This PR change the way this translator work | X-Ray PMs agree on rolling out this change by using feature-gate

🚀 New components 🚀

  • awss3receiver: Initial implementation of the AWS S3 receiver. (#30750)

  • receiver/mysql: Adds INFORMATION_SCHEMA TABLES metrics (#32693)
    This adds table size metrics using the INFORMATION_SCHEMA TABLES table: https://dev.mysql.com/doc/refman/8.3/en/information-schema-tables-table.html.
    Specifically, we are adding the columns: TABLE_ROWS, AVG_ROW_LENGTH, DATA_LENGTH, INDEX_LENGTH.

  • exporter/otelarrow: Implementation copied from opentelemetry/otel-arrow repository @v0.23.0. (#26491)

💡 Enhancements 💡

  • filelogreceiver: Add container operator parser (#31959)

  • jsonlogencodingextension: Move jsonlogencodingextension to alpha (#32697)

  • exceptionsconnector: Make span name a default dimension for ouput metrics and log records. (#32162)

  • azureblobreceiver: Support service principal authentication for Blob storage (#32705)

  • deltatocumulativeprocessor: exponential histogram accumulation (#31340)
    accumulates exponential histogram datapoints by adding respective bucket counts. also handles downscaling, changing zero-counts, offset adaptions and optional fields

  • sumologicexporter: add sticky session support (#32315)

  • elasticsearchexporter: Replace go-elasticsearch BulkIndexer with go-docappender (#32378)
    Replace go-elasticsearch BulkIndexer with go-docappender bulk indexer, in preparation for future reliability fixes.
    As a result of this change, there are minor behavioral differences:

    • flush timeout is now enforced on client side
    • oversize payload special handling is now removed
    • go-docappender uses bulk request filterPath which means bulk response is smaller, less JSON parsing and lower CPU usage
    • document level retry debug logging is removed as retries are done transparently

  • elasticsearchexporter: Converts more SemConv fields in OTel events to ECS fields in Elasticsearch documents when mapping.mode: ecs is specified. (#31694)

  • extension/storage/filestorage: New flag cleanup_on_start for the compaction section (default=false). (#32863)
    It will remove all temporary files in the compaction directory (those which start with tempdb),
    temp files will be left if a previous run of the process is killed while compacting.

  • opampsupervisor: Allows the supervisor to persist its instance ID between restarts. (#21073)

  • opampsupervisor: Adds the ability to configure the agent description (#32824)

  • vcenterreceiver: Refactors how and when client makes calls in order to provide for faster collection times. (#31837)

  • resourcedetectionprocessor: Support GCP Bare Metal Solution in resource detection processor. (#32985)

  • splunkhecreceiver: Make the channelID header check case-insensitive and allow hecreceiver endpoints able to extract channelID from query params (#32995)

  • processor/transform: Allow common where clause (#27830)

  • loadbalancingexporter: Improve the performance when merging traces belonging to the same backend (#32032)

  • pkg/ottl: Added support for timezone in Time converter (#32140)

  • jsonlogencodingextension: Adds a new encoding option for JSON log encoding exension to grab attributes and resources from a log and output that in JSON format. (#32679)

  • probabilisticsamplerprocessor: Adds the FailClosed flag to solidify current behavior when randomness source is missing. (#31918)

  • prometheusremotewriteexporter: Add exporter.prometheusremotewritexporter.RetryOn429 feature gate to retry on http status code 429 response. (#31032)
    The feature gate is initially disabled by default.

  • vcenterreceiver: Changing various default configurations for vcenterreceiver and removing warnings about future release. (#32803, #32805, #32821, #32531, #32557)
    The resource attributes that will now be enabled by default are vcenter.datacenter.name, vcenter.virtual_app.name,
    vcenter.virtual_app.inventory_path, vcenter.vm_template.name, and vcenter.vm_template.id. The metric
    vcenter.cluster.memory.used will be removed. The metrics vcenter.cluster.vm_template.count and
    vcenter.vm.memory.utilization will be enabled by default.

  • sqlserverreceiver: Add metrics for database status (#29865)

  • sqlserverreceiver: Add more metrics (#29865)
    Added metrics are:

🧰 Bug fixes 🧰

  • deltatocumulativeprocessor: Evict only stale streams (#33014)
    Changes eviction behavior to only evict streams that are actually stale.
    Currently, once the stream limit is hit, on each new stream the oldest tracked one is evicted.
    Under heavy load this can rapidly delete all streams over and over, rendering the processor useless.

  • elasticsearchexporter: Retried docs are no longer included in failed docs in an edge case where all errors are retriable (#33092)
    Update dep go-docappender to 2.1.2.
    This fixes the bug when all errors are retriable in bulk request response, retried docs will be included in failed docs.

  • cmd/opampsupervisor: The OpAMP supervisor now configures the ppid parameter of the opamp extension, which allows the collector to shut down if the supervisor is no longer running. (#32189)

  • vcenterreceiver: Adds inititially disabled packet drop rate metric for VMs. (#32929)
