v0.101.0

🛑 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.

🚀 New components 🚀

  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.
• (Contrib) sqlserverreceiver: Add metrics for database status (#29865)
• (Contrib) sqlserverreceiver: Add more metrics (#29865)
  Added metrics are:
  • sqlserver.resource_pool.disk.throttled.read.rate

    These metrics are only available when directly connecting to the SQL server instance

🧰 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.

v0.99.0

🛑 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 🚀

• (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)

v0.97.0

⚠️ 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.

  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)exporter/loadbalancing: Fix panic when a sub-exporter is shut down while still handling requests. (#31410)
• (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.
  Metrics extracted using extract_count_metric() now use the more appropriate default unit (1) instead.

v0.94.0

This Splunk OpenTelemetry Collector release includes changes from the opentelemetry-collector v0.94.1 and the opentelemetry-collector-contrib v0.94.0 releases where appropriate.

🛑 Breaking changes 🛑

• (Splunk) The Splunk OpenTelemetry Collector Windows install script
  now installs the Splunk Distribution of OpenTelemetry .NET
  instead of the SignalFx Instrumentation for .NET
  when the parameter -with_dotnet_instrumentation is set to $true (#4343)
• (Core) receiver/otlp: Update gRPC code from codes.InvalidArgument to codes.Internal when a permanent error doesn't contain a gRPC status (#9415)
• (Contrib) kafkareceiver: standardizes the default topic name for metrics and logs receivers to the same topic name as the metrics and logs exporters of the kafkaexporter (#27292)
  If you are using the Kafka receiver in a logs and/or a metrics pipeline
  and you are not customizing the name of the topic to read from with the topic property,
  the receiver will now read from otlp_logs or otlp_metrics topic instead of otlp_spans topic.
  To maintain previous behavior, set the topic property to otlp_spans.
• (Contrib) pkg/stanza: Entries are no longer logged during error conditions. (#26670)
  This change is being made to ensure sensitive information contained in logs are never logged inadvertently.
  This change is a breaking change because it may change user expectations. However, it should require
  no action on the part of the user unless they are relying on logs from a few specific error cases.
• (Contrib) pkg/stanza: Invert recombine operator's 'overwrite_with' default value. (#30783)
  Previously, the default value was oldest, meaning that the recombine operator should emit the
  first entry from each batch (with the recombined field). However, the actual behavior was inverted.
  This fixes the bug but also inverts the default setting so as to effectively cancel out the bug fix
  for users who were not using this setting. For users who were explicitly setting overwrite_with,
  this corrects the intended behavior.

🚩 Deprecations 🚩

• (Core) configgrpc: Deprecate GRPCClientSettings, use ClientConfig instead (#6767)

💡 Enhancements 💡

• (Splunk) Add a resource attribute to internal metrics to track discovery usage (#4323)
• (Splunk) Create a multi-architecture Windows docker image for the collector (#4296)
• (Splunk) Bump splunk-otel-javaagent to v1.30.2 (#4300)
• (Core) mdatagen: Add a generated test that checks the config struct using componenttest.CheckConfigStruct (#9438)
• (Core) component: Add component.UseLocalHostAsDefaultHost feature gate that changes default endpoints from 0.0.0.0 to localhost (#8510)
  The only component in this repository affected by this is the OTLP receiver.
• (Core) confighttp: Add support of Host header (#9395)
• (Core) mdatagen: Remove use of ReportFatalError in generated tests (#9439)
• (Contrib) receiver/journald: add a new config option "all" that turns on full output from journalctl, including lines that are too long. (#30920)
• (Contrib) pkg/stanza: Add support in a header configuration for json array parser. (#30321)
• (Contrib) awss3exporter: Add the ability to export trace/log/metrics in OTLP ProtoBuf format. (#30682)
• (Contrib) dockerobserver: Upgrading Docker API version default from 1.22 to 1.24 (#30900)
• (Contrib) filterprocessor: move metrics from OpenCensus to OpenTelemetry (#30736)
• (Contrib) groupbyattrsprocessor: move metrics from OpenCensus to OpenTelemetry (#30763)
• (Contrib) loadbalancingexporter: Optimize metrics and traces export (#30141)
• (Contrib) all: Add component.UseLocalHostAsDefaultHost feature gate that 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) processor/resourcedetectionprocessor: Detect Azure cluster name from IMDS metadata (#26794)
• (Contrib) processor/transform: Add copy_metric function to allow duplicating a metric (#30846)

🧰 Bug fixes 🧰

• (Splunk) Fixes the value of a default environment variable used by Windows msi. (#4361)
• (Core) service: fix opencensus bridge configuration in periodic readers (#9361)
• (Core) otlpreceiver: Fix goroutine leak when GRPC server is started but HTTP server is unsuccessful (#9165)
• (Core) otlpexporter: PartialSuccess is treated as success, logged as warning. (#9243)
• (Contrib) basicauthextension: Accept empty usernames. (#30470)
  Per https://datatracker.ietf.org/doc/html/rfc2617#section-2, username and password may be empty strings ("").
  The validation used to enforce that usernames cannot be empty.
• (Contrib) pkg/ottl: Fix parsing of string escapes in OTTL (#23238)
• (Contrib) pkg/stanza: Recombine operator should always recombine partial logs (#30797)
  Previously, certain circumstances could result in partial logs being emitted without any
  recombiniation. This could occur when using is_first_entry, if the first partial log from
  a source was emitted before a matching "start of log" indicator was found. This could also
  occur when the collector was shutting down.
• (Contrib) pkg/stanza: Fix bug where recombine operator's 'overwrite_with' condition was inverted. (#30783)
• (Contrib) exporter/signalfx: Use "unknown" value for the environment correlation calls as fallback. (#31052)
  This fixed the APM/IM correlation in the Splunk Observability UI for the users that send traces with no "deployment.environment" resource attribute value set.
