v0.82.0

The OpenTelemetry Collector Contrib contains everything in the opentelemetry-collector release, be sure to check the release notes there as well.

🛑 Breaking changes 🛑

• receiver/awsfirehose: Change the type of Config.AccessKey to be configopaque.String (#17273)

• receiver/cloudfoundry: Change the type of Config.UAA.Password to be configopaque.String (#17273)

• exporter/datasetexporter: Remove temporary client side attribute aggregation and corresponding traces.max_wait and traces.aggregate config options which are now redundant. (#20660)
  This pull request removes the following attributes from the DataSet trace events: services,
  span_count, error_count. Those attributes were populated on the client side as part of the client
  side aggregation code. This client side aggregation was meant as a temporary solution until a
  proper solution is implement on the server side. Being a temporary solution meant it had many
  edge cases and would only work under specific and limited circumstances (all spans which belong
  to a trace are part of the same batch received by the plugin).

  Corresponding config options (traces.aggregate and traces.max_wait) which are not redundant and
  unused have also been removed.

• mysqlreceiver: removing mysql.locked_connects metric which is replaced by mysql.connection.errors (#23211)

• pkg/ottl: Allow access to the metrics slice in the metric context (#24446)
  This is only a breaking change for users using OTTL in custom components. For all Contrib components this is an enhancement.

• pkg/stanza: Make fileconsumer.PositionalScanner internal (#23999)

• pkg/stanza: Make fileconsumer.Fingerprint internal (#23998)

• receiver/httpcheck: Fail fast on endpoint missing scheme (#23020)
  Previously, when configured with an endpoint without HTTP/HTTPS scheme like "opentelemetry.io",
  the receiver would start correctly, but fail to check the endpoint, producing the httpcheck.error
  metric on every collection interval. After this change, the receiver fails to start, writing
  an error log saying that you need to provide a scheme in the endpoint.

• receiver/jmx: Change the types of Config.{Password,KeystorePassword,TruststorePassword} to be configopaque.String (#17273)

• httpcheckreceiver: support scraping multiple targets (#18823)

• resourcedetectionprocessor: Disable host.id by default on the system detector. This restores the behavior prior to v0.72.0 when using the system detector together with other detectors that set host.id (#21233)
  To re-enable host.id on the system detector set system::resource_attributes::host.id::enabled to true:

  resourcedetection:
    detectors: [system]
    system:
      resource_attributes:
        host.id:
          enabled: true

• receiver/postgresql: Change the type of Config.Password to be configopaque.String (#17273)

• prometheusreciever: Remove unused buffer_period and buffer_count configuration options (#24258)

• prometheusreceiver: Add the trim_metric_suffixes configuration option to allow enable metric suffix trimming. (#21743, #8950)
  When enabled, suffixes for unit and type are trimmed from metric names.
  If you previously enabled the pkg.translator.prometheus.NormalizeName
  feature gate, you will need to enable this option to have suffixes trimmed.

• receiver/pulsar: Change the types of Config.Authentication.Token.Token and Config.Authentication.Athenz.PrivateKey to be configopaque.String (#17273)

• receiver/rabbitmq: Change the type of Config.Password to be configopaque.String (#17273)

• receiver/snowflake: Change the type of Config.Password to be configopaque.String (#17273)

• receiver/solace: Change the type of Config.Auth.PlainText.Password to be configopaque.String (#17273)

• spanmetricsconnector: Histograms will not have exemplars by default (#23872)
  Previously spanmetricsconnector would attach every single span as an exemplar to the histogram.
  Exemplars are now disabled by default. To enable them set exemplars::enabled=true

  cgroup version mounted in the host is v2 instead of v1.

  Now there is documentation of which metrics are available depending cgroups version being used on the host.

🚩 Deprecations 🚩

• mysqlreceiver: set mysql.locked_connects as optional in order to remove it in next release (#14138, #23274)

💡 Enhancements 💡

• hostmetricsreceiver: Add new Windows-exclusive process.handles metric. (#21379)

• websocketprocessor: Rename websocketprocessor to remoteobserverprocessor (#23856)

• resourcedetectionprocessor: Adds a way to configure the list of added resource attributes by the processor (#21482)
  Users can now configure what resource attributes are gathered by specific detectors.
  Example configuration:

  resourcedetection:
    detectors: [system, ec2]
    system:
      resource_attributes:
        host.name:
          enabled: true
        host.id:
          enabled: false
    ec2:
      resource_attributes:
        host.name:
          enabled: false
        host.id:
          enabled: true
  

  For example, this config makes host.name being set by system detector, and host.id by ec2 detector.
  Moreover:

  • Existing behavior remains unaffected as all attributes are currently enabled by default.
  • The default attributes 'enabled' values are defined in metadata.yaml.
  • Future releases will introduce changes to resource_attributes enabled values.
  • Users can tailor resource detection process to their needs and environment.

• spanmetricsconnector: Added disabling options for histogram metrics and option to exclude default labels from all metrics. In some cases users want to optionally disable part of metrics because they generate too much data or are not needed. (#16344)

• statsdreceiver: All receivers are setting receiver name and version when sending data. This change introduces the same behaviour to the statsd receiver. (#23563)

• zookeeperreceiver: Adds an additional health check metric based off of the response from the zookeeper ruok 4lw command. (#21481)

• k8sclusterreceiver: Switch k8s.pod and k8s.container metrics to use pdata. (#23441)

🧰 Bug fixes 🧰

• mongodbreceiver: Fix missing version in mongodb creating panics during scrapes (#23859)
• postgresqlreceiver: fixed an issue where postgresql receiver was emitting the same attribute value "toast_hit" twice under postgresql.blocks_read metric. (#23657)

🛑 Breaking changes 🛑

• redisreceiver: Updates metric unit from no unit to Bytes. (#23454)
  Affected metrics can be found below.

  • redis.clients.max_input_buffer
  • redis.clients.max_output_buffer
  • redis.replication.backlog_first_byte_offset

• nginxreceiver: Bump 'receiver.nginx.emitConnectionsCurrentAsSum' featuregate to beta (enabled by default) (#4326)

• servicegraphprocessor: Change metric names to match the spec (#18743, #16578)
  Latency metric traces_service_graph_request_duration_seconds are deprecated in favor of server and client metrics | traces_service_graph_server_request_seconds and traces_service_graph_client_request_seconds | respectively. Use the feature gate processor.servicegraph.legacyLatencyMetricNames to enable the old metric names.

• prometheusreceiver, prometheusexporter, prometheusremotewrite: Disable pkg.translator.prometheus.NormalizeName feature gate by default (#23208)
  The feature gate pkg.translator.prometheus.NormalizeName was enabled prematurely while translation
  on the prometheus receiver was incomplete. To address this, the feature gate has been reverted back to alpha status.
  This will remain the case until the translation on the receiver side aligns with the translation on the exporter side,
  or until it is replaced with a configuration option or completely removed. To maintain the current behavior, you can
  enable the feature gate using the --feature-gates=pkg.translator.prometheus.NormalizeName command argument.
  However, please note that the translation in the prometheus receiver is a subject to future changes.

• windowseventlogreceiver: Emit raw Windows events as strings instead of byte arrays (#22704)
• receiver/httpcheck: Removed the default endpoint value of http://localhost:80. The endpoint property is now required. (#22995)
• pkg/ottl: Removes StandardTypeGetter in favor of StandardStringGetter, StandardIntGetter, StandardFloatGetter, and StandardPMapGetter, which handle converting pcommon.Values of the proper type. (#22763)
  This is only a breaking change for users using OTTL in custom components. For all Contrib components this is an enhancement.
• postgresqlreceiver: Remove resource attribute feature gates (#22479)

🚩 Deprecations 🚩

• dockerstatsreceiver: cpu.container.percent metric will be deprecated in v0.79.0 in favor of container.cpu.utilization (#21807)
  This starts the process of phasing out incorrect metric name:
  • container.cpu.utilization
    and replacing it with the names adhering to the semantic conventions:
  • container.cpu.percent
    At this stage, the new metric is added, but is disabled by default.
    See the "Deprecations" section of the Docker Stats receiver's README for details.

💡 Enhancements 💡

• receiver/azuremonitorreceiver: Retrieve metric values with all dimension keys in filter (#21715)

• solacereceiver: Updated solacereceiver to handle new features of Solace PubSub+ 10.4.1 (#22809)

• splunkhecreceiver: Support different strategies for splitting payloads when receiving a request with the Splunk HEC receiver. (#22788)

• exporter/splunk_hec: Apply compression to Splunk HEC payload unconditionally if it's enabled in the config. (#22969, #22018)
  The compression used to be enabled only if the payload size was greater than 1.5KB which significantly
  complicated the logic and made it hard to test. This change makes the compression unconditionally applied to
  the payload if it's enabled in the config. The benchmarking shows improvements in the throughput and CPU usage for
  large payloads and expected degradation for small payloads which is acceptable given that it's not a common case.
