This Splunk OpenTelemetry Collector release includes changes from the opentelemetry-collector v0.160.0
and the opentelemetry-collector-contrib v0.160.0 releases where appropriate.
🛑 Breaking changes 🛑
- (Splunk)
config: Improve sourcetype assignment in Linux log collection config to better replicate Splunk TA for *nix behavior (#7843)- Replace hardcoded
linux:varlogsourcetype with dynamic filename-based assignment matching Splunk's default behavior - Add
transform/nix_sourcetypeprocessor with path-based overrides from Splunk TA for *nixprops.conf(e.g.auth.log->syslog,secure->linux_secure,audit.log->linux_audit) - Change
bash_historysourcetype fromlinux:bash_historytobash_historyto match TAinputs.conf - Assign
config_filesourcetype to files with config extensions (.conf,.cfg,.ini, etc.) - Exclude vim swap files (
*.swp,*.swx) fromfile_log/varlog - Not a direct replacement for the Splunk Add-on for Unix and Linux; content-based detection, scripted inputs, and additional field extractions are not implemented
- Replace hardcoded
- (Splunk)
instrumentation: Use the official OpenTelemetry injector release instead of the custom injector shim for auto-instrumentation. (#7581)
This is a breaking change for existing auto-instrumentation installations. Configuration files moved from
/etc/splunk/zeroconfig/to/etc/opentelemetry/injector/(default_env.confandinjector.conf). Existing
values are not migrated automatically. During upgrade, the legacy files are copied to
/usr/lib/splunk-instrumentation/legacy-zeroconfig/before/etc/splunk/zeroconfig/is removed.
Migrate customOTEL_*andSPLUNK_*values fromjava.conf,node.conf, anddotnet.conftodefault_env.conf
before upgrading; values with other prefixes, includingJAVA_TOOL_OPTIONS,NODE_OPTIONS,CORECLR_*, and
DOTNET_*, are ignored. The injector derives activation settings from agent paths ininjector.confinstead.
default_env.confis shared by all runtimes, and runtime-specific values must be configured through the relevant
application or service environment. When a variable is set in both an application or service environment and
default_env.conf, the value fromdefault_env.conftakes precedence, preserving the injector's behavior.
Package upgrades remove the legacy/usr/lib/splunk-instrumentation/libsplunk.soentry and delete an otherwise-empty
preload file. The installer adds the new entry and recreates the file when needed. Restart instrumented applications
or services, or reboot, after updating the preload entry or configuration.
To remove the preserved legacy configuration during an explicit package removal, set
REMOVE_LEGACY_CONFIG=truewhen invoking the package manager. Cleanup is skipped if the backup directory is absent.
.NET agent files are now installed undersplunk-otel-dotnet/glibc, withOTEL_DOTNET_AUTO_HOMEset to that
directory. The installer's--with-instrumentationoption requires an auto-instrumentation package version greater
than 0.159.0.
.NET auto-instrumentation now supports arm64 in addition to amd64. - (Splunk)
scriptedinputsreceiver: Remove the deprecatedscripted_inputsreceiver. (#6893)
Thescripted_inputsreceiver is no longer available. Use thesplunk_inputsreceiver instead, see
the Linux and the Windows
examples. NOTICE: at this momentsplunk_inputsis only available if the featuregateenableTArunneris enabled
as in the linked examples. - (Contrib)
all: Increase minimum Go version to 1.26 (#50394) - (Contrib)
exporter/kafka: Removes the deprecated auth.tls and auth.plain_text configurations. (#50202) - (Contrib)
exporter/signalfx: Datapoints that fail validation are no longer dropped in the exporter. This may increase the ingestsf.org.numDatapointsDroppedInvalidorg metric. No action required; (#50011)
Previously, the SignalFx exporter dropped datapoints with an invalid metric name, dimension name, dimension value, or number of
dimensions before sending them to the backend. The backend already enforces the same constraints and drops offending datapoints at
ingest, so this exporter-side enforcement was redundant. With this change, the exporter no longer drops these datapoints itself and
only logs a debug message; the backend will now drop them. As a result, these datapoints now count toward
sf.org.numDatapointsDroppedInvalid. - (Contrib)
pkg/kafka/configkafka: Remove all previously deprecated Kafka client configuration options. (#50381)
The following deprecated options are no longer accepted:resolve_canonical_bootstrap_servers_only(no-op since franz-go migration)auth.sasl.version(no-op since franz-go migration)group_rebalance_strategy(usegroup_rebalance_strategiesinstead)
- (Contrib)
processor/k8s_attributes: Promoteprocessor.k8sattributes.telemetry.*feature gates from alpha to beta (enabled by default). (#45871)
The following feature gates are now enabled by default:processor.k8sattributes.telemetry.enableNewFormatMetrics: enables new-format internal telemetry metrics.processor.k8sattributes.telemetry.disableOldFormatMetrics: disables old-format internal telemetry metrics.
Users relying on the old-format metrics should migrate to the new format before upgrading.
- (Contrib)
processor/k8s_attributes: Remove the deprecateddeployment_name_from_replicasetoption. (#45871)
Thedeployment_name_from_replicasetkey must be removed from all configs entirely.
Because confmap rejects unknown keys, any config that still contains this setting — whether
set totrueorfalse— will cause a hard startup failure.
Deployment names are always derived from the ReplicaSet name heuristic; the ReplicaSet
informer still runs whenk8s.deployment.uidis enabled or deployment/replicaset
labels/annotations are extracted. Users that had this setting asfalsecan get the same
informer-based behaviour by following the respective documentation
section. - (Contrib)
receiver/systemd: Add metrics for services' memory current and peak memory usage. (#50035)
NOTE: Marked as breaking only because new metrics are enabled by default, potentially impacting resource usage and billing.
🚩 Deprecations 🚩
- (Core)
pkg/confighttp: Deprecate flat keepalive fields in client and server config in favor of the newkeepalivesection. (#14020)
The following client configuration fields are deprecated in favor of thekeepalivesection:idle_conn_timeout->keepalive::idle_conn_timeoutmax_idle_conns->keepalive::max_idle_connsmax_idle_conns_per_host->keepalive::max_idle_conns_per_hostdisable_keep_alives: true->keepalive::enabled: false
The following server configuration fields are deprecated in favor of thekeepalivesection:idle_timeout->keepalive::idle_timeoutkeep_alives_enabled: false->keepalive::enabled: false
Deprecated fields set in the configuration keep working exactly as before and produce a
deprecation warning when the client or server is created. Setting deprecated fields together
with the newkeepalivesection is an error.
Code migrating off the deprecated fields can use the newNewDefaultKeepaliveClientConfig
andNewDefaultKeepaliveServerConfigfunctions to build akeepalivesection with the
default values.
- (Contrib)
exporter/prometheus_remote_write: Deprecateresource_to_telemetry_conversionin favor ofresource_constant_labelsand add feature gateexporter.prometheusremotewrite.DisableResourceToTelemetryConversion. (#48862) - (Contrib)
receiver/icmp_check: Renameicmpcheckreceiverreceiver toicmp_checkwith deprecated aliasicmpcheckreceiver(#45339) - (Contrib)
receiver/windows_perf_counters: Rename the 'windowsperfcounters' receiver to 'windows_perf_counters'. The old 'windowsperfcounters' type remains available as a deprecated alias. (#45339)
🚀 New components 🚀
- (Splunk)
oracleencodingextension: Add theoracle_encodingextension, which unmarshals OCI (Oracle Cloud Infrastructure) Monitoring metrics published in JSONL format into OpenTelemetry metrics. (#7824) - (Splunk)
receiver/promql: New component able to query Prometheus and Thanos and render results as metrics (#8011)
💡 Enhancements 💡
- (Splunk)
installer: Add demonstration of redaction & transform processors. (#7957)
Redaction and transform processors can be used to mask sensitive data like usernames, IP addresses etc. - (Splunk)
receiver/gnmireceiver: Addenum_valuesmetric config option to emit the full state set (active value 1, others 0) for string leaves with a known, closed set of values, instead of only the current value. (#7918) - (Splunk)
packaging: Use SHA-256 instead of MD5 for per-file digests in newly built Collector and auto-instrumentation RPMs. (#7995)
Existing published RPMs are unchanged. Newly built packages require RPM 4.6 or later. - (Splunk)
collector: Publish the baseline and pkg/* Go modules as version tags on each release, so external consumers can import them at a stable released version (#8044) - (Splunk)
packaging: Update Splunk OpenTelemetry Java agent to v2.31.0 (#7982) - (Splunk)
packaging: Update Splunk OpenTelemetry Java agent to v2.31.1 (#8036) - (Splunk)
installer: Use query parameter of Windows Event Log Receiver. (#7953)
Query parameter with select/suppress subtags gives more flexibility than channel and exclude_providers parameters. - (Core)
all: Bump Go version in all go.mod to 1.26.0, drop support on 1.25.0 (#15799) - (Core)
all: Declare windows/amd64 tier 1 and windows/arm64 tier 2 support (#15786) - (Core)
pkg/exporterhelper: Cache the request size per sizer type so byte-sized batching no longer recomputes the serialized proto size of the whole accumulated batch on every consumed request. (#12636)
Withsizer: bytes, the batcher's MinSize check calledBytesSize(), which
ignored the cached size and re-walked the entire batch's protobuf on every
consumed request, making accumulation O(n^2) in the number of merged requests.
The size is now cached separately for the bytes and items dimensions and
maintained incrementally during merge/split, so the check is O(1). A single
untyped cache could not be reused safely because the batcher and the queue may
ask for different sizer types on the same request. - (Core)
processor/memory_limiter: Only report memory limiter component health status when the health state changes. (#15751) - (Contrib)
cmd/opampsupervisor: Add support fortelemetry.resource.detection/developmentin OpAMP Supervisor telemetry. (#45116)
This follows the OpenTelemetry configuration schema by treating
telemetry.resource.detection/development.detectorsas detector selection.
Currently supported detector entries arecontainer,host,process, andservice.
See the OpenTelemetry Configuration Go support table and search for
ExperimentalResourceDetectorfor current detector support:
https://github.com/open-telemetry/opentelemetry-configuration/blob/main/language-support-status.md#go
Example:
telemetry:
resource:
attributes:
- name: foo
value: bar
detection/development:
detectors:
- host: {} - (Contrib)
exporter/awss3: Honor the S3 client's request checksum calculation setting (including theAWS_REQUEST_CHECKSUM_CALCULATIONenvironment variable) when uploading objects. (#50184)
The transfer manager previously always defaulted to calculating a CRC32 checksum, which is sent as
an aws-chunked trailer that some S3-compatible backends reject. It now inherits the setting from the
configured S3 client. - (Contrib)
exporter/kafka: Allow sending more than one signal to the same Kafka topic withsignal_header. (#50244)
Setsignal_header: trueand point each signal'stopicat the same name. You can
enable the setting while topics stay separate. Existing receivers ignore the extra
header, so current per-signal topics keep working. Do not write mixed signals to a
receiver that does not havesignal_headerenabled. While this option is on,
otelcol.signalcannot be set inrecord_headersorinclude_metadata_keys. - (Contrib)
exporter/load_balancing: Avoid quadratic re-hashing when assembling per-endpoint metric batches, most visible with the streamID routing key on high-cardinality workloads. (#49725)
Merging N routed batches into an endpoint's payload re-computed the identity hash of every
already-merged ResourceMetrics/ScopeMetrics/Metric on each merge, making a ConsumeMetrics call
O(N^2) in the number of routed batches. The identities of the accumulated payload are now cached
while merging, which makes the assembly O(N). With 1000 resources (2 metrics x 2 datapoints each) routed by streamID
across 5 endpoints, ConsumeMetrics goes from ~50ms to ~12ms; in production CPU profiles of a
streamID-keyed load balancer, this re-hashing accounted for the majority of total CPU time. - (Contrib)
exporter/prometheus_remote_write: Send the start timestamp of cumulative sums, histograms and summaries asstart_timestampwhen using the Remote Write 2.0 protobuf message. (#50089) - (Contrib)
exporter/prometheus_remote_write: Addresource_constant_labelsoption to transform OTLP resource attributes into Prometheus constant labels. (#48862)
Supports specifying wildcard patterns viaincludedandexcludedlists to selectively transform resource attributes into labels in compliance with the OTel Prometheus specification. - (Contrib)
extension/bearertokenauth: Addretry_on_failureandwait_for_token_fileconfig to retry reading the token file during startup when it is not yet available. (#50122)
Useful when the token file (e.g. a Kubernetes-mounted secret) is provisioned shortly after the
collector starts. Configureenabled,max_retries, andintervalunderretry_on_failure.
Setwait_for_token_fileto block startup until the token file is read instead of retrying in
the background. - (Contrib)
extension/opamp: Avoid sending duplicate health status updates to the OpAMP server (#50197) - (Contrib)
pkg/fileconsumer: Add opt-inskip_unmodified_filesconfig option that skips opening and fingerprinting a file when its path and mtime match a previously tracked reader. (#47861)
Whenskip_unmodified_filesis set totrue, the matcher stats each candidate
path up front and consults the existing reader state (previousPollFiles and the
knownFilesgeneration window) for a match on path+mtime. On match the tracked
metadata is promoted into the current generation and the file is skipped entirely
for this poll: no open, no fingerprint, no read. This avoids wasted IO on files
that haven't been modified since the last poll. The option defaults tofalse,
preserving the existing fingerprint-based behavior. The retention of the new
LastObservedPath/LastObservedMtimefields follows the same lifecycle as
the reader itself, so the skip coherence cannot outlive the reader metadata
it relies on. - (Contrib)
pkg/ottl: Improve syntax error messages to report the position and nearby source, and give odd-length byte literals a clearer error. (#50526) - (Contrib)
pkg/ottl: Adds the clear function to OTTL. (#48714) - (Contrib)
pkg/resourcetotelemetry: AddIncludedandExcludedpattern matching toSettings. (#48861, #48862)
Supports wildcard patterns viaincludedandexcludedlists to selectively convert resource attributes to telemetry attributes, and deprecatesEnabledandExcludeServiceAttributes. - (Contrib)
processor/k8s_attributes: Add support for extracting labels and annotations from CronJobs. (#50386) - (Contrib)
processor/k8s_attributes: Add support for extracting labels and annotations from ReplicaSets. (#50386) - (Contrib)
processor/resource_detection: Add Azure App Service resource detector (#49616) - (Contrib)
processor/tail_sampling: Add Trace State support forrate_limitingandbytes_limitingpolicies. (#49710) - (Contrib)
processor/transform: Addshared_cacheoption to statement lists (#50563)
This allows sharing caches between multiple sets of statements, which provides
the ability to do coordinated operations across multiple passes over a set of
data. - (Contrib)
receiver/aws_cloudwatch: add cloud.account.id to resource attributes (#45038) - (Contrib)
receiver/docker_stats: Add new metriccontainer.state.statusthat reports number of containers in a given status. Disabled by default (#44428) - (Contrib)
receiver/docker_stats: Add a new metriccontainer.state.health.statusthat reports container health status with attributecontainer.state.health.statewhich can have values 'starting', 'healthy', or 'unhealthy'. Disabled by default. (#50063) - (Contrib)
receiver/elasticsearch: Addcluster_stats_master_onlyandindex_stats_master_onlyconfig options to optionally restrict cluster stats and index stats collection to the cluster's elected master node. (#49937)
This is useful when running one receiver instance per node against the same cluster, to avoid every
instance issuing the same cluster-wide calls on every collection interval. Both options default to
false, preserving existing behavior. - (Contrib)
receiver/elasticsearch: Add an opt-inelasticsearch.cluster.uuidresource attribute that uniquely identifies the cluster. (#50263)
The attribute is disabled by default to preserve backward compatibility. Unlikeelasticsearch.cluster.name,
the cluster UUID is stable across restarts and unique across clusters, so it can be enabled to disambiguate
clusters that share a name. - (Contrib)
receiver/host_metrics: Add feature gates to opt into Process Semantic Conventions RC in the Process scraper (#49708)
Two feature gates control the migration during the transition period:scraper.process.EmitV1SystemConventions(disabled by default): when enabled, emits the metrics
and attributes aligned with the latest semantic conventions.scraper.process.DontEmitV0SystemConventions(disabled by default): when enabled, stops emitting
the legacy metrics and attributes.
Affected metrics includeprocess.cpu.time,process.cpu.utilization,process.disk.io,
process.context_switches,process.paging.faults,process.threads,
process.open_file_descriptors, andprocess.handles.
- (Contrib)
receiver/host_metrics: Create receiver level feature gates for enabling v1 Semantic Conventions (#50252)
Adds receiver-level feature gates to the host metrics receiver that enable all scrapers to emit
v1 semantic conventions. These supersede the per-scraper v1 semantic convention
feature gates. - (Contrib)
receiver/kafka: Add opt-in independent partition processing with bounded per-partition mailboxes. (#50030)
Independent partition processing requiresautocommit.enableto be true. - (Contrib)
receiver/mongodb: Add WiredTiger log, fsync, and concurrent-transaction ticket metrics (#50208)
Five opt-in metrics (disabled by default) read from serverStatus.wiredTiger: mongodb.wt.log.write,
mongodb.wt.log.operation.count, mongodb.wt.log.sync.time, mongodb.wt.fsync.count, and
mongodb.wt.concurrent_transactions.in_use. All emit only on the WiredTiger storage engine. - (Contrib)
receiver/mysql: Add MyISAM key cache metrics to the mysqlreceiver. (#50247) - (Contrib)
receiver/mysql: Add InnoDB row-lock wait count and wait time metrics. (#50172) - (Contrib)
receiver/oracledb: Add opt-in Automatic Storage Management (ASM) diskgroup and disk metrics (oracledb.asm.disk_group.*,oracledb.asm.disk.*). (#50487)
All 5 metrics are disabled by default. Sourced fromV$ASM_DISKGROUP_STATandV$ASM_DISK_STAT,
queried from the regular RDBMS connection (no+ASMinstance connection required). Both views
return zero rows, not an error, on instances that don't use ASM. - (Contrib)
receiver/statsd: Add thereceiver.statsd.monotonicCounterDefaultfeature gate, which when enabled changes the default value ofis_monotonic_counterto true. (#14956)
Most statsd counters are monotonic, but the receiver previously defaultedis_monotonic_counterto
false, producing non-monotonic delta sums that some exporters (e.g. the Prometheus exporter) convert
to gauges. Enabling this alpha feature gate makes counters monotonic by default; explicitly setting
is_monotonic_counterin the receiver config always takes precedence over the gate. - (Contrib)
receiver/vcenter: Add host memory metrics vcenter.host.memory.granted, vcenter.host.memory.active, and vcenter.host.memory.ballooned, all disabled by default. (#48800) - (Contrib)
receiver/windows_perf_counters: Allow Windows performance counter wildcard queries to include their aggregation instance (#29054)
Existinginstances: "*"configurations continue to omit_Total. Useinstances: ["*", "_Total"]to retain it. For a custom aggregate such as_Global_, setaggregation_nameand list that name beside the wildcard to retain it.
🧰 Bug fixes 🧰
- (Splunk)
splunk-connect-for-otlp: Register SIGTERM/SIGINT signal handler early in startup, before blocking auth calls. (#8028) - (Splunk)
packaging: Set syslog identifier to otelcol to ensure Linux journald logs continue outputting with same tag as before. (#8012) - (Splunk)
receiver/gnmireceiver: Fix gnmireceiver silently overwriting datapoint attributes when two path elements reuse the same key name (#7925)
Colliding keys are now namespaced by their owning element (e.g.subinterface.index). - (Core)
pkg/pprofile: add bounds checks to FromLocationIndices and switchDictionary (#15697)
FromLocationIndices now returns an error instead of panicking on an out-of-range or
negative location index, mirroring FromAttributeIndices.
The index checks used when merging profiles now also reject negative indices. These
were previously reachable with a negative index decoded from an OTLP payload, which
panicked the collector via Profiles.MergeTo. - (Core)
pkg/service: Route OpenTelemetry SDK-internal errors (e.g. failed metric/log/trace exports) through the collector's configured logger instead of the OTel SDK's default global error handler, which always printed to stderr vialog.Printregardless of the configured log encoding. (#12378) - (Contrib)
cmd/opampsupervisor: Fix the OpAMP supervisor so that the full effective config map (all named config files) is forwarded to the OpAMP server instead of only the empty-string ("") key (#49902) - (Contrib)
cmd/opampsupervisor: Fix a data race in the commander when the agent process has to be killed after it ignores the graceful shutdown signal. (#49929) - (Contrib)
cmd/opampsupervisor: Fix Supervisor startup failing withcould not get bootstrap info from the Collectorwhen another process is already usinglocalhost:8888(#50608)
The Collector started during bootstrap is only used to report its AgentDescription and is
stopped immediately afterwards, but it applied the default internal telemetry configuration
and bound a Prometheus reader onlocalhost:8888. When that port was already in use the
Collector exited before connecting back to the Supervisor, and startup failed with
could not get bootstrap info from the Collector. The bootstrap Collector's internal
metrics are never collected, so they are now disabled for that invocation only. - (Contrib)
cmd/opampsupervisor: Ignore non-positive HeartbeatIntervalSeconds from OpAMP connection settings and revert the heartbeat interval when reconnecting with new settings fails (#50268)
Previously a ConnectionSettingsOffers message that left HeartbeatIntervalSeconds unset
overwrote the supervisor's current interval with zero, which opamp-go rejects for HTTP
transport and treats as "disable heartbeats" for WebSocket transport. On the HTTP path
the subsequent reconnect failed, and because the old interval was not restored the
fallback reconnect failed the same way, leaving the supervisor permanently disconnected.
Non-positive intervals are now ignored and the previous interval is restored when
reconnecting with new settings fails. - (Contrib)
cmd/opampsupervisor: Fix config validation so effective config cannot mask invalid remote configs. (#50153) - (Contrib)
exporter/prometheus_remote_write: Preserve UTF-8 characters inexternal_labelsnames when usingNoTranslationorNoUTF8EscapingWithSuffixes. (#50435) - (Contrib)
extension/file_storage: Fix nil pointer crash when bbolt database compaction fails during startup after database corruption (#49735)
The file_storage extension now catches panics during on_start compaction and returns
an error instead of crashing the collector. This allows the collector to continue
operating with existing database recovery mechanisms. - (Contrib)
extension/opamp: Avoid requiring host ID when building os.description so OpAMP can start on Windows containers. (#46965)
getOSDescription now uses gopsutil PlatformInformation instead of host.Info,
which fails on Windows containers when MachineGuid is unavailable. - (Contrib)
pkg/ottl: TheIntLikeGetternow returns an error when a string value cannot be parsed as an int (#50564) - (Contrib)
pkg/ottl: Reject malformed list literals that are missing commas between elements or have a leading comma. (#50530) - (Contrib)
pkg/translator/prometheusremotewrite: Fix target_info metric label name translation in PRW exporter to respect UTF-8 / NoTranslation settings. (#50435) - (Contrib)
processor/k8s_attributes: Reject configurations with duplicatepod_associationrules during validation. (#49269)
Two associations that resolve to the same set of sources (ignoring source order) now cause a
validation error. This enforces the uniqueness ofPodIdentifiers that the cache relies on. - (Contrib)
receiver/oracledb: Emitoracledb.plan_hash_valueas the raw value returned by Oracle rather than hex-encoding the string, making it directly correlatable withV$SQL.PLAN_HASH_VALUE. (#50307)
Previously,oracledb.plan_hash_valuewas emitted as a hex-encoding of the ASCII bytes
of the string value (e.g.4199919568became34313939393139353638), making it
impossible to correlate directly withV$SQL.PLAN_HASH_VALUEin Oracle. - (Contrib)
receiver/postgresql: Honorexclude_databasesin the top query and query sample collectors (#50046)
Previously only the metrics path appliedexclude_databases. Statements from excluded databases
were still collected, and the top query collector connected to each one to run EXPLAIN -- which
managed providers reject, for examplerdsadminon Amazon RDS, logging an error on every plan
cache expiry. Both collectors now filter excluded databases server side and no longer connect
to them to run EXPLAIN. - (Contrib)
receiver/prometheus_remote_write: Only convert exemplartrace_idandspan_idlabels that are valid IDs, and keep the rest as filtered attributes (#50547)
Atrace_idorspan_idlabel with an invalid length was previously zero padded
or truncated before being stored in the exemplar. This could create an ID that
the sender never wrote, while the original value was lost. The receiver now
converts only valid IDs with the expected OpenTelemetry width and preserves an
invalid value unchanged as a filtered attribute. - (Contrib)
receiver/prometheus_remote_write: Stop native histogram bucket spans from driving unbounded memory and CPU use. (#50286)
A remote write request could describe a gap of billions of histogram buckets in
a few bytes, and the receiver reserved memory and iterated in proportion to that
gap. Bucket spans are now validated before conversion, and a native histogram is
dropped when its spans are invalid, when it would expand to more than 16384
buckets, or when a request has already used its budget of 4194304 buckets. - (Contrib)
receiver/prometheus_remote_write: Drop the Prometheus overflow bucket when converting native histograms, instead of translating it. (#50292)
The last bucket that maps to a finite OpenTelemetry bucket is 1024*2^schema.
The bucket above it is the Prometheus overflow bucket, which covers values past
the IEEE float range, and the Prometheus compatibility specification requires
overflow buckets to be dropped and left out of the count. It was previously
translated as an ordinary bucket. Buckets above the overflow bucket are not
allowed at all, and a histogram containing one is now dropped. - (Contrib)
receiver/sqlserver: Ensureservice.instance.iduniquely identifies SQL Server named instances when using dynamic ports. (#50535) - (Contrib)
receiver/sqlserver: Skip emitting query sample and top query events whose text is empty or a comment-only placeholder, except idle blocker query samples which are still emitted. (#50219)
SQL Server returns a placeholder line comment (e.g.--*UPDATE----) in place of
data-modifying OPENROWSET statements that carry inline credentials. The obfuscator
strips line comments, leaving an empty query text, so these rows previously emitted
empty query sample and top query events. Such rows are now skipped, with one
exception: idle blocker query samples (command = IDLE_BLOCKER) are still emitted even
when their query text is empty, so the blocking-session information they carry is
preserved. - (Contrib)
receiver/vcenter: Emit VM CPU metrics for idle VMs instead of dropping them (#49643)
A CPU usage of 0 MHz was treated as the VM being unavailable, sovcenter.vm.cpu.usage,
vcenter.vm.cpu.utilizationandvcenter.vm.cpu.readinesswere silently dropped for every
powered on but idle VM. 0 MHz is a valid reading for an idle VM, so availability is now
determined by the VM power state instead. - (Contrib)
receiver/vcenter: added logic so that if a query fails due to a bad object it does not fail the entire scrape (#46977)
