signalfx/splunk-otel-collector v0.103.0

on GitHub

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)
