v0.87.0

This Splunk OpenTelemetry Collector release includes changes from the opentelemetry-collector v0.87.0 and the opentelemetry-collector-contrib v0.87.0 releases where appropriate.

🛑 Breaking changes 🛑

• (Splunk) Auto Instrumentation for Linux (#3791):
  • The /usr/lib/splunk-instrumentation/instrumentation.conf config file is no longer
    supported, and is replaced by /etc/splunk/zeroconfig/java.conf. If the splunk-otel-auto-instrumentation deb/rpm
    package is manually upgraded, the options within /usr/lib/splunk-instrumentation/instrumentation.conf will need to
    be manually migrated to their corresponding environment variables within /etc/splunk/zeroconfig/java.conf.
  • Manual installation of the splunk-otel-auto-instrumentation deb/rpm package no longer automatically adds
    /usr/lib/splunk-instrumentation/libsplunk.so to /etc/ld.so.preload.
  • Manual upgrade of the splunk-otel-auto-instrumentation deb/rpm package will automatically remove
    /usr/lib/splunk-instrumentation/libsplunk.so from /etc/ld.so.preload.
  • The splunk.linux-autoinstr.executions metric is no longer generated by libsplunk.so.
  • See Splunk OpenTelemetry Zero Configuration Auto Instrumentation for Linux
    for manual installation/configuration details.
  • For users of the Ansible, Chef, Puppet, or Salt modules for Auto Instrumentation, it is recommended to update the following option in your configuration for version 0.86.0 or older until these modules are updated to manage these changes:
    • Ansible: splunk_otel_auto_instrumentation_version
    • Chef: auto_instrumentation_version
    • Puppet: auto_instrumentation_version
    • Salt: auto_instrumentation_version
• (Contrib) kubeletstatsreceiver: Fixes a bug where the "insecure_skip_verify" config was not being honored when "auth_type" is "serviceAccount" in kubelet client. (#26319)
  • Before the fix, the kubelet client was not verifying kubelet's certificate. The default value of the config is false,
    so with the fix the client will start verifying tls cert unless the config is explicitly set to true.
• (Contrib) tailsamplingprocessor: Improve counting for the count_traces_sampled metric (#25882)
• (Contrib) extension/filestorage: Replace path-unsafe characters in component names (#3148)
• (Core) service/telemetry exporter/exporterhelper: Enable sampling logging by default and apply it to all components. (#8134)
  • The sampled logger configuration can be disabled easily by setting the service::telemetry::logs::sampling::enabled to false.

🚩 Deprecations 🚩

• (Splunk) The following Auto Instrumentation options for the Linux installer script are deprecated and will only apply if the --instrumentation-version <version> option is specified for version 0.86.0 or older:
  • --[no-]generate-service-name: libsplunk.so no longer generates service names for instrumented applications. The default behavior is for the activated Java and/or Node.js Auto Instrumentation agents to automatically generate service names. Use the --service-name <name> option to override the auto-generated service names for all instrumented applications.
  • --[enable|disable]-telemetry: libsplunk.so no longer generates the splunk.linux-autoinstr.executions telemetry metric.

🚀 New components 🚀

• (Splunk) Add the loadbalancing exporter (#3825)
• (Splunk) Add the udplog receiver (#3826)

💡 Enhancements 💡

• (Splunk) Update golang to 1.20.10 (#3770)
• (Splunk) Add debian 12 support to installer (#3766)
• (Splunk) Add new Auto Instrumentation options for the Linux installer script (#3791):
  • --with[out]-systemd-instrumentation: Activate auto instrumentation for only systemd services without preloading
    the libsplunk.so shared object library (default: --without-systemd-instrumentation)
  • Initial support for Splunk OpenTelemetry Auto Instrumentation for Node.js:
    • Activated by default if the --with-instrumentation or --with-systemd-instrumentation option is specified.
    • Use the --without-instrumentation-sdk node option to explicitly skip Node.js.
    • npm is required to install the Node.js Auto Instrumentation package. If npm is not installed, Node.js will
      be skipped automatically.
    • By default, the Node.js Auto Instrumentation package is installed with the npm install --global command. Use the
      --npm-command "<command>" option to specify a custom command.
    • Environment variables to activate and configure Node.js auto instrumentation are added to /etc/splunk/zeroconfig/node.conf (for --with-instrumentation) or
      /usr/lib/systemd/system.conf.d/00-splunk-otel-auto-instrumentation.conf (for --with-systemd-instrumentation) based on defaults and specified installation options.
  • Auto Instrumentation for Java is also activated by default if the --with-instrumentation or
    --with-systemd-instrumentation option is specified. Use the --without-instrumentation-sdk java option to skip Java.
  • --otlp-endpoint host:port: Set the OTLP gRPC endpoint for captured traces (default: http://LISTEN_INTERFACE:4317
    where LISTEN_INTERFACE is the value from the --listen-interface option if specified, or 127.0.0.1 otherwise)
  • See Linux Installer Script for more details.
• (Splunk) Update splunk-otel-javaagent to v1.29.0 (#3788)

• (Contrib) kubeletstatsreceiver: Support specifying context for kubeConfig auth_type (#26665)
• (Contrib) kubeletstatsreceiver: Adds new k8s.pod.cpu_limit_utilization, k8s.pod.cpu_request_utilization, k8s.container.cpu_limit_utilization, and k8s.container.cpu_request_utilization metrics that represent the ratio of cpu used vs set limits and requests. (#27276)
• (Contrib) kubeletstatsreceiver: Adds new k8s.pod.memory_limit_utilization, k8s.pod.memory_request_utilization, k8s.container.memory_limit_utilization, and k8s.container.memory_request_utilization metrics that represent the ratio of memory used vs set limits and requests. (#25894)

🧰 Bug fixes 🧰

• (Contrib) spanmetricsprocessor: Prune histograms when dimension cache is pruned. (#27080)
  • Dimension cache was always pruned but histograms were not being pruned. This caused metric series created
    by processor/spanmetrics to grow unbounded.
• (Contrib) splunkhecreceiver: Fix receiver behavior when used for metrics and logs at the same time; metrics are no longer dropped. (#27473)
• (Contrib) metricstransformprocessor: Fixes a nil pointer dereference when copying an exponential histogram (#27409)
• (contrib) k8sclusterreceiver: change k8s.container.ready, k8s.pod.phase, k8s.pod.status_reason, k8s.namespace.phase units to empty (#10553)

• (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) 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) 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.
