SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires pyyaml, and includes scripts (resource) and references (resource) components.

What problem does it solve?

Render, apply, verify, and uninstall Splunk Browser RUM and browser-side Digital Experience Analytics (DXA) prerequisites plus optional Session Replay injection for Kubernetes-served frontends. Supports nginx sub_filter, ingress-nginx snippets, initContainer HTML rewrites, runtime config, backup and revert manifests, SplunkRum.init options, Frustration Signals, source-map upload helpers, RUM-to-APM Server-Timing validation, multi-workload specs, distroless detection, version pinning, SRI hashes, IE11 opt-in, and dashboard, detector, SIM, and backend auto-instrumentation handoffs. Use when wiring a React, Vue, Angular, Next.js, Nuxt, Remix, nginx/httpd, SPA, or MPA frontend to Splunk Browser RUM, enabling Session Replay, configuring Frustration Signals, preparing browser-side Digital Experience Analytics (DXA), uploading source maps, validating trace linking, or uninstalling RUM. Do not use for AppDynamics BRUM.

Core Features & Use Cases

  • Render four injection modes for Kubernetes frontends: nginx-configmap, ingress-snippet, init-container, and runtime-config.
  • Optional Enterprise Session Replay integration with per-workload knobs and privacy controls.
  • Built-in source maps workflow with CI snippets and upload helpers; RUM-to-APM trace linking validation.
  • Handoffs to dashboards, detectors, and cloud integration surfaces for observability enablement.
  • Multi-workload support with per-workload mode overrides and guided workflows for safe deployments.

Quick Start

Render the asset manifests with the default render flow and then apply the patches after you confirm credentials and gates are satisfied.

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I instrument a React frontend with Splunk Browser RUM on Kubernetes?▼

You can instrument a React frontend with Splunk Browser RUM on Kubernetes by rendering and applying manifests through one of four injection modes: nginx-configmap, ingress-snippet, init-container, or runtime-config. It also supports Vue, Angular, Next.js, and Nuxt.

What is the best way to enable Splunk Session Replay for multiple Kubernetes workloads?▼

The best way to enable Splunk Session Replay for multiple Kubernetes workloads is using multi-workload specs with per-workload knobs and privacy controls. This allows scalable, secure instrumentation with gated mutations across distinct deployments.

Does Splunk RUM instrumentation support ingress-nginx snippets and initContainer HTML rewrites?▼

Yes, Splunk RUM instrumentation supports ingress-nginx snippets and initContainer HTML rewrites as two of its four injection modes. It also includes nginx sub_filter, runtime config, backup and revert manifests, and distroless detection.

How do I validate RUM-to-APM trace linking and upload source maps for my Kubernetes frontend?▼

Validate RUM-to-APM trace linking by checking Server-Timing validation, and upload source maps using built-in CI snippets and upload helpers. The instrumentation workflow includes these checks to ensure proper observability handoffs.

Can I configure Frustration Signals and DXA prerequisites when wiring Splunk RUM?▼

Yes, you can configure Frustration Signals and prepare browser-side Digital Experience Analytics (DXA) prerequisites when wiring Splunk RUM. The instrumentation process also supports SplunkRum.init options and dashboard or detector handoffs.

When should I not use this approach for browser instrumentation?▼

You should not use this approach for AppDynamics BRUM instrumentation. It is specifically designed for Splunk Browser RUM and browser-side DXA, applying to SPA and MPA frontends served by Kubernetes.
