* feat(bp-grafana): umbrella chart for observability stack Catalyst Blueprint umbrella for Grafana — visualization layer of the LGTM observability stack (Loki/Grafana/Tempo/Mimir). Pinned to grafana/grafana 10.5.15 (appVersion 12.3.1) — current stable on 2026-04-29. Solo-Sovereign defaults: 1 replica, 10Gi PVC, ServiceMonitor disabled per BLUEPRINT-AUTHORING.md §11.2. Part of issue #204 observability-stack umbrellas batch. * feat(bp-loki): umbrella chart for observability stack Catalyst Blueprint umbrella for Grafana Loki — log aggregation backend of the LGTM stack. SingleBinary mode by default (solo-Sovereign min); SimpleScalable/Distributed are values toggles. Pinned to grafana/loki 7.0.0 (appVersion 3.6.7) on 2026-04-29. Filesystem storage default; SeaweedFS S3 wiring is per-Sovereign overlay when scaling out. All observability toggles default false per BLUEPRINT-AUTHORING.md §11.2. Part of issue #204 observability-stack umbrellas batch. * feat(bp-mimir): umbrella chart for observability stack Catalyst Blueprint umbrella for Grafana Mimir — metrics storage tier of the LGTM stack. Pinned to grafana/mimir-distributed 6.0.6 (appVersion 3.0.4) on 2026-04-29. Solo-Sovereign defaults: every component scaled to 1 replica, zoneAwareReplication disabled, Kafka ingest-storage disabled. Bundled MinIO kept enabled as a stop-gap so the chart renders; SeaweedFS S3 wiring is per-Sovereign overlay. All metaMonitoring toggles default false per BLUEPRINT-AUTHORING.md §11.2. Part of issue #204 observability-stack umbrellas batch. * feat(bp-tempo): umbrella chart for observability stack Catalyst Blueprint umbrella for Grafana Tempo — distributed tracing backend of the LGTM stack. Single-binary mode by default (solo-Sovereign min); microservice mode (tempo-distributed) is a chart swap toggle. Pinned to grafana/tempo 1.24.4 (appVersion 2.9.0) on 2026-04-29. Local PVC storage default; SeaweedFS S3 wiring is per-Sovereign overlay. Metrics generator disabled by default (depends on bp-mimir). ServiceMonitor default false per BLUEPRINT-AUTHORING.md §11.2. Part of issue #204 observability-stack umbrellas batch. * feat(bp-alloy): umbrella chart for observability stack Catalyst Blueprint umbrella for Grafana Alloy — unified telemetry collector for the LGTM stack (logs, metrics, traces; OTLP-native). Pinned to grafana/alloy 1.8.0 (appVersion v1.16.0) on 2026-04-29. DaemonSet controller default (one Alloy per node) so node + container telemetry work out of the box. Empty Alloy config by default; per-Sovereign overlays populate forwarders to bp-loki/bp-mimir/bp-tempo once those reconcile. ServiceMonitor + ingress + CRDs default false per BLUEPRINT-AUTHORING.md §11.2. Part of issue #204 observability-stack umbrellas batch. * feat(bp-opentelemetry): umbrella chart for observability stack Catalyst Blueprint umbrella for the OpenTelemetry Collector — vendor- neutral telemetry collector. Sibling to bp-alloy; per-Sovereign overlays choose one. Pinned to open-telemetry/opentelemetry-collector 0.152.0 (appVersion 0.150.1) on 2026-04-29. Uses the contrib distribution (otel/opentelemetry-collector-contrib:0.150.1) so Loki/Mimir/Tempo exporters are bundled. Deployment mode default (1 replica); DaemonSet + StatefulSet are values toggles. All presets default false; ingress + ServiceMonitor + PodMonitor + PrometheusRule + NetworkPolicy default false per BLUEPRINT-AUTHORING.md §11.2. Part of issue #204 observability-stack umbrellas batch. * feat(bp-langfuse): umbrella chart for observability stack Catalyst Blueprint umbrella for Langfuse — LLM observability platform. Complements bp-grafana (infrastructure metrics) with AI-specific telemetry (traces, evaluations, prompts, cost attribution). Pinned to langfuse/langfuse 1.5.28 (appVersion 3.171.0) on 2026-04-29. Catalyst convention: ALL bundled Bitnami subcharts are disabled — PostgreSQL via cnpg.io/Cluster (bp-cnpg), Redis via bp-valkey, ClickHouse via bp-clickhouse, S3 via bp-seaweedfs. Per-Sovereign overlays wire external endpoints + Secret references. Telemetry to Langfuse Inc. defaulted false; signUpDisabled defaulted true. Part of issue #204 observability-stack umbrellas batch. * feat(bp-velero): umbrella chart for observability stack Catalyst Blueprint umbrella for Velero — Kubernetes-native backup and disaster recovery. Per platform/velero/README.md, ALL Velero output goes to SeaweedFS (Catalyst's unified S3 encapsulation), which transitions to a cloud archival backend on the cold tier. Pinned to vmware-tanzu/velero 12.0.1 (appVersion 1.18.0) on 2026-04-29. Bundled velero-plugin-for-aws:v1.14.0 init container so SeaweedFS S3 is reachable. backupsEnabled/snapshotsEnabled defaulted false at this layer (placeholders for backupStorageLocation); per-Sovereign overlays flip on after wiring SeaweedFS endpoint + credentials. ServiceMonitor + PodMonitor + PrometheusRule default false per BLUEPRINT-AUTHORING.md §11.2.

LangFuse
LLM observability and analytics. Application Blueprint (see docs/PLATFORM-TECH-STACK.md §4.7). Traces every LLM call in bp-cortex — latency, tokens, cost, eval scores. Catalyst's general-purpose observability stack (Grafana/OTel) covers infrastructure; LangFuse covers the AI-specific dimensions (prompt/response, model drift, eval).
Category: AI Observability | Type: Application Blueprint
Overview
LangFuse provides tracing, evaluation, and analytics for LLM applications. It captures every LLM call with cost, latency, token usage, and evaluation scores. Complements Grafana (which handles infrastructure metrics) with AI-specific observability.
Key Features
- LLM call tracing (input, output, cost, latency, tokens)
- Prompt management and versioning
- Evaluation scoring and datasets
- User analytics and session tracking
- Cost attribution per model/user/feature
Integration
| Component | Integration |
|---|---|
| LLM Gateway | Automatic trace capture |
| Grafana | Infrastructure metrics complement |
| CNPG | PostgreSQL backend for traces |
| NeMo Guardrails | Traces guardrail activations |
