v0.83.0

🛑 Breaking changes 🛑

• (Splunk) Fluentd installation disabled by default for the splunk-otel-collector salt formula (#3448)
  • Specify the install_fluentd: True attribute in your pillar to enable installation
• (Splunk/Contrib) Removes the deprecated receiver/prometheus_exec receiver. Please see migration guide for further details. (#24740) (#3512)
• (Contrib) receiver/k8scluster: Unify predefined and custom node metrics. (#24776)
  • Update metrics description and units to be consistent
  • Remove predefined metrics definitions from metadata.yaml because they are controlled by node_conditions_to_report
    and allocatable_types_to_report config options.

💡 Enhancements 💡

• (Splunk) Use SPLUNK_LISTEN_INTERFACE and associated installer option to configure the network interface used by the collector for default configurations (#3421)
  • Existing installations will rely on the default value of SPLUNK_LISTEN_INTERFACE set to 0.0.0.0. Users must add SPLUNK_LISTEN_INTERFACE to their collector configuration to take advantage of this new option.
• (Contrib) receiver/collectdreceiver: Migrate from opencensus to pdata, change collectd, test to match pdata format. (#20760)
• (Contrib) pkg/ottl: Add support for using addition and subtraction with time and duration (#22009)
• (Contrib) transformprocessor: Add extract_count_metric OTTL function to transform processor (#22853)
• (Contrib) transformprocessor: Add extract_sum_metric OTTL function to transform processor (#22853)
• (Contrib) prometheusreceiver: Don't drop histograms without buckets (#22070)
• (Contrib) pkg/ottl: Add a new Function Getter to the OTTL package, to allow passing Converters as literal parameters. (#22961)
  Currently OTTL provides no way to use any defined Converter within another Editor/Converter.
  Although Converters can be passed as a parameter, they are always executed and the result is what is actually passed as the parameter.
  This allows OTTL to pass Converters themselves as a parameter so they can be executed within the function.
• (Contrib) resourcedetectionprocessor: GCP resource detection processor can automatically add gcp.gce.instance.hostname and gcp.gce.instance.name attributes. (#24598)
• splunkhecexporter: Add heartbeat check while startup and new config param, heartbeat/startup (defaults to false). This is different than the healtcheck_startup, as the latter doesn't take token or index into account. (#24411)
• (Contrib) hostmetricsreceiver: Report logical and physical number of CPUs as metric. (#22099)
  • Use the system.cpu.logical.count::enabled and system.cpu.physical.count::enabled flags to enable them
• (Contrib) k8sclusterreceiver: Allows disabling metrics and resource attributes (#24568)
• (Contrib) k8sclusterreceiver: Reduce memory utilization (#24769)
• (Contrib) k8sattributes: Added k8s.cluster.uid to k8sattributes processor to add cluster uid (#21974)
• (Contrib) resourcedetectionprocessor: Collect heroku metadata available instead of exiting early. Log at debug level if metadata is missing to help troubleshooting. (#25059)
• (Contrib) hostmetricsreceiver: Improved description of the system.cpu.utilization metrics. (#25115)

• (Contrib) filelogreceiver: Bump 'filelog.allowHeaderMetadataParsing' feature gate to beta (#18198)
• (Contrib) receiver/prometheusreceiver: Add config report-extra-scrape-metrics to report additional prometheus scraping metrics (#21040)
  • Emits additional metrics - scrape_body_size_bytes, scrape_sample_limit, scrape_timeout_seconds. scrape_body_size_bytes metric can be used for checking failed scrapes due to body-size-limit.
• (Contrib) receiver/sqlquery: Set ObservedTimestamp on collected logs (#23776)
• (Core) extension: Add optional ConfigWatcher interface (#6596)
  • Extensions implementing this interface will be notified of the Collector's effective config.
• (Core) otelcol: Add optional ConfmapProvider interface for Config Providers (#6596)
  • This allows providing the Collector's configuration as a marshaled confmap.Conf object from a ConfigProvider
• (Core) service: Add CollectorConf field to service.Settings (#6596)
  This field is intended to be used by the Collector to pass its effective configuration to the service.

🧰 Bug fixes 🧰

• (Contrib) carbonreceiver: Fix Carbon receiver obsrecv operations memory leak (#24275)
  • The carbonreceiver has a memory leak where it will repeatedly open new obsrecv operations but not close them afterwards. Those operations eventually create a burden. The fix is to make sure the receiver only creates an operation per interaction over TCP.

• (Contrib) zipkinreceiver: Respects zipkin's serialised status tags to be converted to span status (#14965)
• (Contrib) processor/resourcedetection: Do not drop all system attributes if host.id cannot be fetched. (#24669)
• (Contrib) signalfxexporter: convert vmpage_io* translated metrics to pages (#25064)
• (Contrib) splunkhecreceiver: aligns success resp body w/ splunk enterprise (#19219)
  • changes resp from plaintext "ok" to json {"text"："success", "code"：0}

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

• (Contrib) 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.

• (Contrib) Set pkg.translator.prometheus.NormalizeName feature gate back to Alpha state since it was enabled
  prematurely. Metrics coming from Prometheus receiver will not be normalized by default, specifically _total suffix
  will not be removed from metric names. To maintain the current behavior (drop the _total suffix), you can enable
  the feature gate using the --feature-gates=pkg.translator.prometheus.NormalizeName command argument. However, note
  that the translation in the prometheus receiver is a subject to possible future changes.

v0.79.0

This Splunk OpenTelemetry Collector release includes changes from the opentelemetry-collector v0.79.0 and the opentelemetry-collector-contrib v0.79.0 releases where appropriate.

🛑 Breaking changes 🛑

• (Contrib) Set pkg.translator.prometheus.NormalizeName feature gate back to Alpha state since it was enabled
  prematurely. Metrics coming from Prometheus receiver will not be normalized by default, specifically _total suffix
  will not be removed from metric names. To maintain the current behavior (drop the _total suffix), you can enable
  the feature gate using the --feature-gates=pkg.translator.prometheus.NormalizeName command argument. However, note
  that the translation in the prometheus receiver is a subject to possible future changes.
  (#23229)
• (Contrib) attributesprocessor: Enable SHA-256 as hashing algorithm by default for attributesprocessor hashing action (#4759)
• (Contrib) windowseventlogreceiver: Emit raw Windows events as strings instead of byte arrays (#22704)
• (Contrib) 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.
• (Contrib) postgresqlreceiver: Remove resource attribute feature gates (#22479)

💡 Enhancements 💡

• (Splunk) smartagentreceiver: Add kubernetes-cluster config option to sync node labels as properties on the kubernetes_node dimension (#3267)
• (Splunk) Discovery mode: Support splunk.discovery mapping in properties.discovery.yaml (#3238)
• (Splunk) Upgrade to the latest Java agent version v1.25.0 (#3272)
• (Contrib) jmxreceiver: Add the JMX metrics gatherer version 1.26.0-alpha to the supported jars hash list (#22042)
• (Contrib) receivers: Adding initial_delay to receivers to control when scraping interval starts (#23030)
  The updated receivers are:
  • oracledb
  • postgresql
  • sqlquery
  • windowsperfcounters
• (Contrib) oracledbreceiver: Add a simpler alternative configuration option (#22087)
• (Contrib) pkg/ottl: Add body.string accessor to ottllog (#22786)
• (Contrib) pkg/ottl: Allow indexing map and slice log bodies (#17396, #22068)
• (Contrib) pkg/ottl: Add hash converters/functions for OTTL (#22725)
• (Contrib) splunkhecreceiver: Support different strategies for splitting payloads when receiving a request with the Splunk HEC receiver (#22788)
• (Contrib) 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.
• (Core) otelcol: Add connectors to output of the components command (#7809)
• (Core) scraperhelper: Will start calling scrapers on component start. (#7635)
  The change allows scrapes to perform their initial scrape on component start
  and provide an initial delay. This means that scrapes will be delayed by initial_delay
  before first scrape and then run on collection_interval for each consecutive interval.
• (Core) batchprocessor: Change multiBatcher to use sync.Map, avoid global lock on fast path (#7714)
• (Core, Contrib, Splunk) Third-party dependency updates.

🧰 Bug fixes 🧰

• (Splunk) smartagentreceiver add missing monitorID logger field to http monitor (#3261)
• (Contrib) jmxreceiver: Fixed the issue where the JMX receiver's subprocess wasn't canceled upon shutdown, resulting in a rogue java process. (#23051)
• (Contrib) internal/filter/filterlog: fix filtering non-string body by bodies property (#22736)
  Affects filterprocessor and attributesprocessor.
• (Contrib) prometheusreceiver: Remove sd_file validations from config.go in Prometheus Receiver to avoid failing Collector with error as this behaviour is incompatible with the Prometheus. (#21509)
• (Contrib) fileexporter: Fixes broken lines when rotation is set. (#22747)
• (Contrib) exporter/splunk_hec: Make sure the max_event_size option is used to drop events larger than max_event_size instead of using it for batch size. (#18066)
• (Contrib) postgresqlreceiver: Fix race condition when capturing errors from multiple requests simultaneously (#23026)
• (Contrib) prometheusreceiver: The prometheus receiver now sets a full, versioned user agent. (#21910)
• (Contrib) splunkhecreceiver: Fix reusing the same splunkhecreiver between logs and metrics (#22848)
• (Core) connectors: When replicating data to connectors, consider whether the next pipeline will mutate data (#7776)
