[chart] Address deprecation warnings by crobert-1 · Pull Request #2326 · signalfx/splunk-otel-collector-chart

crobert-1 · 2026-03-25T23:24:54Z

Description:

When the gateway and agent are started, warnings are logged that deprecated aliases are being used:

2026-03-25T21:49:17.560Z	warn	builders/builders.go:40	"otlphttp" alias is deprecated; use "otlp_http" instead	{"resource": {"service.instance.id": "c4e676c9-949d-46fa-ab11-51e0b579d7cd", "service.name": "otel-agent", "service.version": "v0.147.0"}, "otelcol.component.id": "otlphttp/entities", "otelcol.component.kind": "exporter", "otelcol.signal": "logs"}
...
2026-03-25T21:49:17.561Z	warn	builders/builders.go:40	"otlphttp" alias is deprecated; use "otlp_http" instead	{"resource": {"service.instance.id": "c4e676c9-949d-46fa-ab11-51e0b579d7cd", "service.name": "otel-agent", "service.version": "v0.147.0"}, "otelcol.component.id": "otlphttp", "otelcol.component.kind": "exporter", "otelcol.signal": "traces"}
...
2026-03-25T21:49:17.561Z	warn	builders/builders.go:40	"k8sattributes" alias is deprecated; use "k8s_attributes" instead	{"resource": {"service.instance.id": "c4e676c9-949d-46fa-ab11-51e0b579d7cd", "service.name": "otel-agent", "service.version": "v0.147.0"}, "otelcol.component.id": "k8sattributes", "otelcol.component.kind": "processor", "otelcol.pipeline.id": "traces", "otelcol.signal": "traces"}

This updates the chart to reference the new aliases rather than the deprecated ones. Marked as breaking change in case users are directly referencing the configured components in custom configs.

Pull request overview

Updates the Splunk OpenTelemetry Collector for Kubernetes Helm chart (and its related tests/examples) to use the non-deprecated OpenTelemetry Collector component names (e.g., otlp_http, k8s_attributes) to eliminate deprecation warnings at runtime.

Changes:

Replace deprecated component aliases (otlphttp, k8sattributes) with separated component names (otlp_http, k8s_attributes) in chart templates and values docs.
Update unit/functional tests and golden files to reflect new component IDs.
Regenerate example rendered manifests (checksums/config) and add a new histogram-example example set.

+  [`otlp_http`
  exporter](https://github.com/open-telemetry/opentelemetry-collector/tree/main/exporter/otlphttpexporter).


The Markdown link text for the OTLP HTTP exporter is missing a closing backtick (and is split across lines), which breaks inline code formatting and may break the link rendering. Consider keeping the link text on a single line and ensuring the code span is properly closed (e.g., otlp_http).

Suggested change

controlPlaneMetrics.etcd.secret.clientCert is documented as a PEM-format client certificate, but this example uses a BEGIN PUBLIC KEY block. Please switch to a proper certificate PEM (BEGIN CERTIFICATE) or clearly mark as placeholder to avoid users copying an invalid setup.

This example includes an actual-looking BEGIN PRIVATE KEY block under clientKey. Avoid committing private key material in-repo; replace with a redacted/obviously fake placeholder and instruct users to provide this via an external Kubernetes Secret.

 {{- define "splunk-otel-collector.k8sAttributesProcessor" -}}
-k8sattributes:
+k8s_attributes:
  pod_association:


This change renames the processor ID from k8sattributes to k8s_attributes, which also changes the value reported in collector internal metrics labels (e.g., the processor label). The functional test golden file functional_tests/functional/testdata/expected_kind_values/expected_internal_metrics.yaml still expects k8sattributes/k8sattributes/metrics, so make functionaltest is likely to fail unless those expected results are regenerated/updated to the new component IDs.

Changelog note says “Rename all otlphttp exporter references…”. Since this is specifically about the Helm chart’s generated collector config (and it’s a breaking change mainly for users overriding *.config.exporters.otlphttp / *.config.service.pipelines.*.exporters), consider tightening the wording to that scope and/or explicitly calling out the affected override keys so users know what to update.

This affects the Helm chart's generated collector configuration. It is a breaking change for

users who override collector settings via values such as:

- `*.config.exporters.otlphttp`

- `*.config.service.pipelines.*.exporters` entries that reference `otlphttp`

Update these overrides to use `otlp_http` instead of `otlphttp`.

Test helm install in GCE (kops) - credentials needed is failing due to a repo secret referencing the otlp exporter. Once this PR is merged we'll need to update the secret.

@crobert-1 i believe this config and a 2nd one here in test values are causing the install to fail and should be updated

Thanks @jinja2, I didn't see that file because I hadn't rebased 🤦 Updated

failOnDeprecatedNames assumes .config.exporters/.config.processors are maps and pipeline exporters/processors are lists. If a user supplies an unexpected type (e.g., exporters: "otlphttp" via --set), range will iterate a string and hasPrefix will receive non-strings, causing a template runtime error instead of a clear validation failure. Consider guarding with kindIs "map" / kindIs "slice" (or coercing with toString) before iterating, and failing with an explicit message when types are invalid.

Grammar nit: this comment now says “a otlp_grpc exporter”; since it starts with a vowel sound, it should be “an otlp_grpc exporter”.

We'll have to include receiver filelog -> file_log to this list after upgrade to v0.149.0
