v0.104.0

This Splunk OpenTelemetry Collector release includes changes from the opentelemetry-collector v0.104.0 and the opentelemetry-collector-contrib v0.104.0 releases where appropriate.

⚠️ In our efforts to align with the goals defined upstream for environment variable resolution in the Collector's configuration, the Splunk OpenTelemetry Collector will be dropping support for expansion of BASH-style environment variables, such as $FOO in the configuration in an upcoming version. Users are advised to update their Collector's configuration to use ${env:FOO} instead.
🚩 When setting properties for discovery receiver as environment variables (SPLUNK_DISCOVERY_*), the values cannot reference other environment variables without curly-braces. For example, user is trying to set discovery property SPLUNK_DISCOVERY_EXTENSIONS_k8s_observer_ENABLED to the value of another env var, K8S_ENVIRONMENT.
For versions older than 0.104.0, setting it as SPLUNK_DISCOVERY_EXTENSIONS_k8s_observer_ENABLED=\$K8S_ENVIRONMENT (note the escaped variable name does not have curly braces) was valid. But from v0.104.0, env var names need to be passed with braces. For this example, user should modify it to SPLUNK_DISCOVERY_EXTENSIONS_k8s_observer_ENABLED=\${K8S_ENVIRONMENT}.

❗ Known Issues ❗

• A bug was discovered (and fixed in a future version) where expansion logic in confmaps wasn't correctly handling the escaping of $$ (#10560)
  • If you rely on the previous functionality, disable the confmap.unifyEnvVarExpansion feature gate. Note that this is a temporary workaround, and the root issue will be fixed in the next release by (#10560).

🛑 Breaking changes 🛑

• (Splunk) Auto Discovery for Linux:
  • Update splunk-otel-java to v2.5.0 for the splunk-otel-auto-instrumentation deb/rpm packages. This is a major version bump that includes breaking changes. Check the release notes for details about breaking changes.
• (Core) filter: Remove deprecated filter.CombinedFilter (#10348)
• (Core) otelcol: By default, otelcol.NewCommand and otelcol.NewCommandMustSetProvider will set the DefaultScheme to env. (#10435)
• (Core) expandconverter: By default expandconverter will now error if it is about to expand $FOO syntax. Update configuration to use ${env:FOO} instead or disable the confmap.unifyEnvVarExpansion feature gate. (#10435)
• (Core) otlpreceiver: Switch to localhost as the default for all endpoints. (#8510)
  Disable the component.UseLocalHostAsDefaultHost feature gate to temporarily get the previous default.
• (Splunk) discovery: When setting properties for discovery receiver as environment variables (SPLUNK_DISCOVERY_*), the values cannot reference other escaped environment variables without braces. For example, when trying to set discovery property SPLUNK_DISCOVERY_EXTENSIONS_k8s_observer_ENABLED to the value of another env var, K8S_ENVIRONMENT. For versions older than 0.104.0, setting it as SPLUNK_DISCOVERY_EXTENSIONS_k8s_observer_ENABLED=\$K8S_ENVIRONMENT (note the escaped variable name does not have braces) was valid. But from v0.104.0, env var names need to be passed with braces. For this example, user should modify it to SPLUNK_DISCOVERY_EXTENSIONS_k8s_observer_ENABLED=\${K8S_ENVIRONMENT}
• (Contrib) vcenterreceiver: Drops support for vCenter 6.7 (#33607)
• (Contrib) all: Promote component.UseLocalHostAsDefaultHost feature gate to beta. This changes default endpoints from 0.0.0.0 to localhost (#30702)
  This change affects the following components:
  • extension/health_check
  • receiver/jaeger
  • receiver/sapm
  • receiver/signalfx
  • receiver/splunk_hec
  • receiver/zipkin
• (Contrib) receiver/mongodb: Graduate receiver.mongodb.removeDatabaseAttr feature gate to stable (#24972)

💡 Enhancements 💡

• (Splunk) Auto Discovery for Linux:
  • Linux installer script:
    • The default for the --otlp-endpoint option is now empty, i.e. defers to the default OTEL_EXPORTER_OTLP_ENDPOINT value for each activated SDK
    • Add new --otlp-endpoint-protocol <protocol> option to set the OTEL_EXPORTER_OTLP_PROTOCOL environment variable for the configured endpoint. Only applicable if the --otlp-endpoint option is also specified.
    • Add new --metrics-exporter <exporter> option to configure the OTEL_METRICS_EXPORTER environment variable for instrumentation metrics. Specify none to disable metric collection and export.
• (Splunk) Set Go garbage collection target percentage to 400% (#5034)
  After removal of memory_ballast extension in v0.97.0, the Go garbage collection is running more aggressively, which
  increased CPU usage and leads to reduced throughput of the collector. This change reduces the frequency of garbage
  collection cycles to improves performance of the collector for typical workloads. As a result, the collector will
  report higher memory usage, but it will be bound to the same configured limits. If you want to revert to the previous
  behavior, set the GOGC environment variable to 100.
• (Splunk) Upgrade to golang 1.21.12 (#5074)
• (Core) confighttp: Add support for cookies in HTTP clients with cookies::enabled. (#10175)
  The method confighttp.ToClient will return a client with a cookiejar.Jar which will reuse cookies from server responses in subsequent requests.
• (Core) exporter/debug: In normal verbosity, display one line of text for each telemetry record (log, data point, span) (#7806)
• (Core) exporter/debug: Add option use_internal_logger (#10226)
• (Core) configretry: Mark module as stable. (#10279)
• (Core) exporter/debug: Print Span.TraceState() when present. (#10421)
  Enables viewing sampling threshold information (as by OTEP 235 samplers).
• (Core) processorhelper: Add "inserted" metrics for processors. (#10353)
  This includes the following metrics for processors:
  • processor_inserted_spans
  • processor_inserted_metric_points
  • processor_inserted_log_records
• (Contrib) k8sattributesprocessor: Add support for exposing k8s.pod.ip as a resource attribute (#32960)
• (Contrib) vcenterreceiver: Adds vCenter CPU readiness metric for VMs. (#33607)
• (Contrib) receiver/mongodb: Ensure support of 6.0 and 7.0 MongoDB versions with integration tests (#32716)

v0.103.0

This Splunk OpenTelemetry Collector release includes changes from the opentelemetry-collector v0.103.0 and the opentelemetry-collector-contrib v0.103.0 releases where appropriate.

🛑 Breaking changes 🛑

• (Core) exporter/debug: Disable sampling by default (#9921)
  To restore the behavior that was previously the default, set sampling_thereafter to 500.
• (Contrib) mongodbreceiver: Now only supports TCP connections (#32199)
  This fixes a bug where hosts had to explicitly set tcp as the transport type. The transport option has been removed.
• (Contrib) sqlserverreceiver: sqlserver.database.io.read_latency has been renamed to sqlserver.database.latency with a direction attribute. (#29865)

🚀 New components 🚀

• (Splunk) Add Azure Monitor receiver (#4971)
• (Splunk) Add upstream Opentelemetry Collector RabbitMQ receiver (#4980)
• (Splunk) Add Active Directory Domain Services receiver (#4994)
• (Splunk) Add Splunk Enterprise receiver (#4998)

💡 Enhancements 💡

• (Core) otelcol/expandconverter: Add confmap.unifyEnvVarExpansion feature gate to allow enabling Collector/Configuration SIG environment variable expansion rules. (#10391)
  When enabled, this feature gate will:
  • Disable expansion of BASH-style env vars ($FOO)
  • ${FOO} will be expanded as if it was ${env:FOO}
    See https://github.com/open-telemetry/opentelemetry-collector/blob/main/docs/rfcs/env-vars.md for more details.
• (Core) confmap: Add confmap.unifyEnvVarExpansion feature gate to allow enabling Collector/Configuration SIG environment variable expansion rules. (#10259)
  When enabled, this feature gate will:
  • Disable expansion of BASH-style env vars ($FOO)
  • ${FOO} will be expanded as if it was ${env:FOO}
    See https://github.com/open-telemetry/opentelemetry-collector/blob/main/docs/rfcs/env-vars.md for more details.
• (Core) confighttp: Allow the compression list to be overridden (#10295)
  Allows Collector administrators to control which compression algorithms to enable for HTTP-based receivers.
• (Core) configgrpc: Revert the zstd compression for gRPC to the third-party library we were using previously. (#10394)
  We switched back to our compression logic for zstd when a CVE was found on the third-party library we were using. Now that the third-party library has been fixed, we can revert to that one. For end-users, this has no practical effect. The reproducers for the CVE were tested against this patch, confirming we are not reintroducing the bugs.
• (Core) confmap: Adds alpha confmap.strictlyTypedInput feature gate that enables strict type checks during configuration resolution (#9532)
  When enabled, the configuration resolution system will:
  • Stop doing most kinds of implicit type casting when resolving configuration values
  • Use the original string representation of configuration values if the ${} syntax is used in inline position
• (Core) confighttp: Use confighttp.ServerConfig as part of zpagesextension. See server configuration options. (#9368)
• (Contrib) filelogreceiver: If include_file_record_number is true, it will add the file record number as the attribute log.file.record_number (#33530)
• (Contrib) filelogreceiver: Add support for gzip compressed log files (#2328)
• (Contrib) kubeletstats: Add k8s.pod.cpu.node.utilization metric (#33390)
• (Contrib) awss3exporter: endpoint should contain the S3 bucket (#32774)
• (Contrib) statsdreceiver: update statsd receiver to use mdatagen (#33524)
• (Contrib) statsdreceiver: Added received/accepted/refused metrics (#24278)
• (Contrib) metricstransformprocessor: Adds the 'count' aggregation type to the Metrics Transform Processor. (#24978)
• (Contrib) tailsamplingprocessor: Simple LRU Decision Cache for "keep" decisions (#31583)
• (Contrib) tailsamplingprocessor: Migrates internal telemetry to OpenTelemetry SDK via mdatagen (#31581)
  The metric names and their properties, such as bucket boundaries for histograms, were kept like before, to keep backwards compatibility.
• (Contrib) kafka: Added disable_fast_negotiation configuration option for Kafka Kerberos authentication, allowing the disabling of PA-FX-FAST negotiation. (#26345)
• (Contrib) pkg/ottl: Added keep_matching_keys function to allow dropping all keys from a map that don't match the pattern. (#32989)
• (Contrib) pkg/ottl: Add debug logs to help troubleshoot OTTL statements/conditions (#33274)
• (Contrib) pkg/ottl: Introducing append function for appending items into an existing array (#32141)
• (Contrib) pkg/ottl: Introducing Uri converter parsing URI string into SemConv (#32433)
• (Contrib) probabilisticsamplerprocessor: Add Proportional and Equalizing sampling modes (#31918)
  Both the existing hash_seed mode and the two new modes use OTEP 235 semantic conventions to encode sampling probability.
• (Contrib) prometheusreceiver: Resource attributes produced by the prometheus receiver now include stable semantic conventions for server and url. (#32814)
  To migrate from the legacy net.host.name, net.host.port, and http.scheme resource attributes, migrate to server.address, server.port, and url.scheme, and then set the receiver.prometheus.removeLegacyResourceAttributes feature gate.
• (Contrib) spanmetricsconnector: Produce delta temporality span metrics with StartTimeUnixNano and TimeUnixNano values representing an uninterrupted series (#31671, #30688)
  This allows producing delta span metrics instead of the more memory-intensive cumulative metrics, specifically when a downstream component can convert the delta metrics to cumulative.
• (Contrib) sqlserverreceiver: Add support for more Database IO metrics (#29865)
  The following metrics have been added:
  • sqlserver.database.latency
  • sqlserver.database.io
  • sqlserver.database.operations
• (Contrib) processor/transform: Add transform.flatten.logs featuregate to give each log record a distinct resource and scope. (#32080)
  This option is useful when applying transformations which alter the resource or scope. e.g. set(resource.attributes["to"], attributes["from"]), which may otherwise result in unexpected behavior. Using this option typically incurs a performance penalty as the processor must compute many hashes and create copies of resource and scope information for every log record.
• (Contrib) receiver/windowsperfcounters: Counter configuration now supports recreating the underlying performance query at scrape time. (#32798)

🧰 Bug fixes 🧰

• (Core) exporterhelper: Fix potential deadlock in the batch sender (#10315)
• (Core) expandconverter: Fix bug where an warning was logged incorrectly. (#10392)
• (Core) exporterhelper: Fix a bug when the retry and timeout logic was not applied with enabled batching. ([#10166](https://github.com/open-telemetry/opentelemetry-colle...

v0.102.1

This Splunk OpenTelemetry Collector release includes changes from the opentelemetry-collector v0.102.1 and the opentelemetry-collector-contrib v0.102.0 releases where appropriate.

🧰 Bug fixes 🧰

• (Core) configrpc: This release addresses GHSA-c74f-6mfw-mm4v for configgrpc. (#10323)
  Before this change, the zstd compressor that was used didn't respect the max message size. This addresses GHSA-c74f-6mfw-mm4v on configgrpc.

v0.102.0

This Splunk OpenTelemetry Collector release includes changes from the opentelemetry-collector v0.102.0 and the opentelemetry-collector-contrib v0.102.0 releases where appropriate.

🛑 Breaking changes 🛑

• (Splunk) receiver/discovery: Replace log_record field with message in evaluation statements (#4583)
• (Core) envprovider: Restricts Environment Variable names. Environment variable names must now be ASCII only and start with a letter or an underscore, and can only contain underscores, letters, or numbers. (#9531)
• (Core) confighttp: Apply MaxRequestBodySize to the result of a decompressed body #10289
  When using compressed payloads, the Collector would verify only the size of the compressed payload.
  This change applies the same restriction to the decompressed content. As a security measure, a limit of 20 MiB was added, which makes this a breaking change.
  For most clients, this shouldn't be a problem, but if you often have payloads that decompress to more than 20 MiB, you might want to either configure your
  client to send smaller batches (recommended), or increase the limit using the MaxRequestBodySize option.
• (Contrib) k8sattributesprocessor: Move k8sattr.rfc3339 feature gate to stable. (#33304)
• (Contrib) extension/filestorage: Replace path-unsafe characters in component names (#3148)
  The feature gate extension.filestorage.replaceUnsafeCharacters is now removed.
• (Contrib) vcenterreceiver: vcenterreceiver replaces deprecated packet metrics by removing them and enabling by default the newer ones. ((#32929),(#32835)
  Removes the following metrics: vcenter.host.network.packet.errors, vcenter.host.network.packet.count, and
  vcenter.vm.network.packet.count.
  Also enables by default the following metrics: vcenter.host.network.packet.error.rate,
  vcenter.host.network.packet.rate, and vcenter.vm.network.packet.rate.

v0.101.0

This Splunk OpenTelemetry Collector release includes changes from the opentelemetry-collector v0.101.0 and the opentelemetry-collector-contrib v0.101.0 releases where appropriate.

🛑 Breaking changes 🛑

• (Splunk) receiver/discovery: Remove append_pattern option from log evaluation statements (#4583)
  • The matched log message is now set as discovery.matched_log entity attributes instead of being appended to
    the discovery.message attribute.
  • The matched log fields like caller and stacktrace are not sent as attributes anymore.
• (Contrib) 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).
• (Contrib) resourcedetectionprocessor: Move processor.resourcedetection.hostCPUModelAndFamilyAsString feature gate to stable. (#29025)
• (Contrib) 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.

v0.99.0

This Splunk OpenTelemetry Collector release includes changes from the opentelemetry-collector v0.99.0 and the opentelemetry-collector-contrib v0.99.0 releases where appropriate.

🛑 Breaking changes 🛑

• (Splunk) receiver/discovery: Update the component to emit entity events
  • The log_endpoints config option has been removed. Endpoints are now only reported if they match the configured receiver rules, and are now emitted as entity events.
    (#4692, #4684,
    #4684, and #4691)
• (Core) telemetry: Distributed internal metrics across different levels. (#7890)
  The internal metrics levels are updated along with reported metrics:
  • The default level is changed from basic to normal, which can be overridden with service::telmetry::metrics::level configuration.
  • Batch processor metrics are updated to be reported starting from normal level:
    • processor_batch_batch_send_size
    • processor_batch_metadata_cardinality
    • processor_batch_timeout_trigger_send
    • processor_batch_size_trigger_send
  • GRPC/HTTP server and client metrics are updated to be reported starting from detailed level:
    • http.client.* metrics
    • http.server.* metrics
    • rpc.server.* metrics
    • rpc.client.* metrics
  • Note: These metrics are all excluded by default in the Splunk distribution of the OpenTelemetry Collector.
    This change only affects users who have modified the default configuration's dropping rules (metric_relabel_configs)
    in the Prometheus receiver that scrapes internal metrics.
• (Contrib) extension/filestorage: Replace path-unsafe characters in component names (#3148)
  The feature gate extension.filestorage.replaceUnsafeCharacters is now stable and cannot be disabled.
  See the File Storage extension's README for details.
• (Contrib) exporter/loadbalancing: Change AWS Cloud map resolver config fields from camelCase to snake_case. (#32331)
  The snake_case is required in OTel Collector config fields. It used to be enforced by tests in cmd/oteltestbedcol,
  but we had to disable them. Now, the tests are going to be enforced on every component independently.
  Hence, the camelCase config fields recently added with the new AWS Cloud Map resolver has to be fixed.
• (Splunk) smartagent/collectd-mongodb: Monitor has been removed to resolve CVE-2024-21506 (#4731)

🚀 New components 🚀

• (Splunk) Add ack extension (#4724)

💡 Enhancements 💡

• (Splunk) Include splunk-otel-dotnet in the splunk-otel-auto-instrumentation deb/rpm packages (x86_64/amd64 only) (#4679)
  • Note: Only manual activation/configuration for .NET auto instrumentation is currently supported. See README.md for details.
• (Splunk) Update splunk-otel-javaagent to v1.32.0 (#4715)
• (Splunk) Enable collecting MSI information on Windows in the support bundle (#4710)
• (Splunk) Bump version of bundled Python to 3.11.9 (#4729)
• (Splunk) receiver/mongodb: Enable auto-discovery when TLS is disabled (#4722)
• (Core) confighttp: Disable concurrency in zstd compression (#8216)
• (Core) cmd/mdatagen: support excluding some metrics based on string and regexes in resource_attributes (#9661)
• (Contrib) vcenterreceiver: Changes process for collecting VMs & VM perf metrics used by the vccenterreceiver to be more efficient (one call now for all VMs) (#31837)
• (Contrib) splunkhecreceiver: adding support for ack in the splunkhecreceiver (#26376)
• (Contrib) hostmetricsreceiver: The hostmetricsreceiver now caches the system boot time at receiver start and uses it for all subsequent calls. The featuregate hostmetrics.process.bootTimeCache can be disabled to restore previous behaviour. (#28849)
  This change was made because it greatly reduces the CPU usage of the process and processes scrapers.
• (Contrib) filelogreceiver: Add send_quiet and drop_quiet options for on_error setting of operators (#32145)
• (Contrib) pkg/ottl: Add IsList OTTL Function (#27870)
• (Contrib) filelogreceiver: Add exclude_older_than configuration setting (#31053)
• (Contrib) pkg/stanza/operator/transformer/recombine: add a new "max_unmatched_batch_size" config parameter to configure the maximum number of consecutive entries that will be combined into a single entry before the match occurs (#31653)

v0.97.0

This Splunk OpenTelemetry Collector release includes changes from the opentelemetry-collector v0.97.0 and the opentelemetry-collector-contrib v0.97.0 releases where appropriate.

⚠️ Upgrade guidelines regarding the collector memory ballast. ⚠️

reproduced from repository README

memory_ballast is no longer effective. The garbage collection is now controlled by the soft memory limit set to 90% of total memory (SPLUNK_MEMORY_TOTAL_MIB env var) by default.

If you haven't customized the memory_ballast, just remove it from the configuration.

If you have customized it via SPLUNK_BALLAST_SIZE_MIB (or extensions::memory_ballast::size_mib config), you should remove the memory_ballast extension and use the GOMEMLIMIT environment variable to set a custom soft memory limit:

To increase frequency of garbage collections: set GOMEMLIMIT to a higher value than the default 90% of total memory.
To decrease frequency of garbage collections: set GOMEMLIMIT to a lower value than the default 90% of total memory.

🚀 New components 🚀

• (Contrib) deltatocumulativeprocessor: introduce configurable stream limit (#31488)
  Adds max_streams option that allows to set upper bound (default = unlimited)
  to the number of tracked streams. Any additional streams exceeding the limit
  are dropped.
• (Contrib) fileexporter: Adopt the encoding extension with the file exporter. (#31774)
• (Contrib) pkg/ottl: Add ParseXML function for parsing XML from a target string. (#31133)

  See https://prometheus.io/docs/prometheus/latest/configuration/configuration/#configuration-file for details on setting scrape_protocols.
• (Contrib) vcenterreceiver: Fixed the resource attribute model to more accurately support multi-cluster deployments (#30879)
  For more information on impacts please refer open-telemetry/opentelemetry-collector-contrib#31113. The main impacts are that
  the vcenter.resource_pool.name, vcenter.resource_pool.inventory_path, and vcenter.cluster.name are reported with more accuracy on VM metrics.

🧰 Bug fixes 🧰

• (Splunk) telemetry: Simplify the config converter setting the metric_relabel_configs in the Prometheus receiver
  to remove the excessive internal metrics. Now, it only overrides the old default rule excluding .*grpc_io.* metrics.
  Any other custom setting is left untouched. Otherwise, customizing the metric_relabel_configs is very difficult.

• (Contrib) hostmetricsreceiver: Adds the receiver.hostmetrics.normalizeProcessCPUUtilization feature gate to optionally normalize process.cpu.utilization values. (#31368)
  When enabled, the receiver.hostmetrics.normalizeProcessCPUUtilization feature gate will cause process.cpu.utilization values to be divided by the number of logical cores on the system. This is necessary to produce a value on the interval of [0-1], as the description of process.cpu.utilization the metric says.
• (Contrib) transformprocessor: Change metric unit for metrics extracted with extract_count_metric() to be the default unit (1) (#31575)
  The original metric unit does not apply to extracted count metrics the same way it does to sum, min or max.
