Ring:creating Grafana Dashboards

Creating Grafana Dashboards (lib-observability, PM-team)

When to use

Sweep mode:

• "Create / scaffold Grafana dashboards for this service"
• "Inventory telemetry / build telemetry dictionary"
• "Audit observability before designing dashboards"
• "Produce dashboards as code for {service}"
• "PM wants visibility into {domain} — what dashboards do we need?"

Reference mode:

• "What's the right panel for HTTP request latency?"
• "RED vs USE methodology for this metric type?"
• "How do I compose Grafonnet panels?"
• "Which Grafonnet template fits a counter / histogram / gauge?"

Skip when

• Service is not a Go project (lib-observability is Go-only at this skill's scope)
• Service emits no telemetry (pre-instrumentation; instrument the service before dashboard authoring, then use ring:dev-implementation to verify observability checks pass)
• Task is purely Grafana folder organization or dashboard import (no authoring)
• Service is consumer-only sidecar with no metrics surface

Prerequisites

• Go service with lib-observability initialized in bootstrap (tracing.NewTelemetry, metrics.NewFactory, zap.NewLogger)
• At least one metric, span, or structured log emission point present
• docs/ directory writable
• Grafonnet toolchain available in CI (jsonnet + grafonnet-lib) — installer instructions in ci-drift-check.md

Orchestrates a 3-phase, 8-gate workflow to produce Grafana dashboards grounded in real telemetry. You orchestrate. Agents explore. PM iterates. You NEVER read, write, or edit source code directly during the sweep.

Telemetry Architecture (lib-observability)

Lerian Go services emit telemetry through github.com/LerianStudio/lib-observability:

• Tracing via lib-observability/tracing — tracer.Start(ctx, name, opts...) returning context.Context, trace.Span
• Metrics via lib-observability/metrics — fluent factory producing meter.Int64Counter, meter.Float64Histogram, meter.Int64UpDownCounter, meter.Int64ObservableGauge
• Logs via lib-observability/log (interface) and lib-observability/zap (implementation) — structured fields, automatically correlated with active span via trace_id/span_id
• OTel attribute / metric / event names via lib-observability/constants — canonical string constants; dashboards reference these for label and metric names
• Cross-cutting — tenant_id propagation through context, error attribution via span.RecordError + span.SetStatus

Deprecated shims: lib-commons/v5/commons/{opentelemetry,zap,log,metrics} still compile but route through lib-observability. New emission sites MUST import lib-observability directly. The sweep detects both canonical and shim imports.

Authoring Format: Grafonnet (Mandatory)

Dashboards are authored as Grafonnet (Jsonnet templating language) — compiled to JSON in CI. Raw JSON dashboards are FORBIDDEN.

Reasons:

• Diffable in PR review (libsonnet is code-shaped, JSON is not)
• Composable via import and inheritance
• Templated panel patterns reusable across themes
• Single source of truth — JSON is a build artifact, not a checked-in source

Toolchain setup: sub-files/ci-drift-check.md. Panel templates: sub-files/grafonnet-templates/.

Theme Taxonomy

Free-form per service. PM defines the theme directories under docs/dashboards/{theme}/ during Gate 5. No enforced taxonomy — Lerian services are observability islands and theme naming reflects each service's domain.

Common-but-not-mandatory examples: transactions/, auth/, ledger/, infrastructure/, business-kpis/, sla/. The skill SUGGESTS themes from dictionary contents in Gate 4; PM ACCEPTS, RENAMES, MERGES, or SPLITS in Gate 5.

Drift Gate Posture

CI drift detection is BLOCKING from day 1. Any divergence between regenerated dictionary and committed telemetry-dictionary.md fails the PR. This is a deliberate cold-start choice — the skill is greenfield, no installed base to retrofit, every new metric emits under the strict regime.

Drift gate spec: sub-files/ci-drift-check.md.

Gate Overview

Gates execute sequentially. Gate 1 parallelizes internally across 7 angles. Gate 6 parallelizes per approved theme.

Gate 0: Stack Detection

Orchestrator executes directly. Detect in parallel:

1. Go version:                grep "^go " go.mod | head -1
2. lib-observability version: grep "lib-observability" go.mod
3. lib-commons version:       grep "lib-commons" go.mod
4. Tracing package present:   grep -rn "lib-observability/tracing\|lib-commons/v5/commons/opentelemetry" internal/ cmd/   # canonical + deprecated shim
5. Metrics package present:   grep -rn "lib-observability/metrics\|lib-commons/v5/commons/opentelemetry" internal/ cmd/   # canonical + deprecated shim
6. Meter init:                grep -rn "Meter(\|NewMeter\|meter.Int64Counter\|meter.Float64Histogram" internal/ cmd/
7. Tracer init:               grep -rn "Tracer(\|NewTracer\|tracer.Start" internal/ cmd/
8. Log emission:              grep -rn "lib-observability/log\|lib-observability/zap\|lib-commons/v5/commons/log\|lib-commons/v5/commons/zap" internal/ cmd/   # canonical + deprecated shim
9. HTTP framework:            grep -rn "gofiber/fiber\|labstack/echo\|gin-gonic" go.mod
10. gRPC server:              grep -rn "grpc.NewServer" internal/ cmd/
11. RabbitMQ command consumers: grep -rn "lib-commons/v5/commons/rabbitmq" internal/ cmd/   # command queues; event emission goes through lib-streaming
12. lib-streaming present:    grep "lib-streaming" go.mod
13. Tenant source:            grep -rn "tmcore.GetTenantIDContext\|GetTenantID" internal/
14. Existing dictionary:      test -f docs/dashboards/telemetry-dictionary.md
15. Existing dashboards:      ls docs/dashboards/ 2>/dev/null
16. Grafonnet in CI:          test -f .github/workflows/telemetry-drift.yml
17. Service identity:         cat go.mod | grep "^module"

Emit /tmp/dashboards-recon.json:

{
  "service_name": "...",
  "go_version": "...",
  "lib_observability_version": "...",
  "lib_commons_version": "...",
  "lib_streaming_present": false,
  "tracing_initialized": true,
  "metrics_initialized": true,
  "metric_emission_present": true,
  "trace_emission_present": true,
  "structured_log_present": true,
  "deprecated_shim_imports": ["lib-commons/v5/commons/opentelemetry"],
  "http_framework": "fiber|echo|gin|none",
  "grpc_server_present": true,
  "rabbitmq_command_consumers_present": true,
  "tenant_source": "tmcore.GetTenantIDContext",
  "existing_dictionary": true,
  "existing_themes": ["transactions", "ledger"],
  "drift_gate_installed": false
}

HARD GATE:

• If not Go → STOP.
  • If no lib-observability tracing/metrics usage detected (canonical or deprecated shim) → STOP, surface "service is not instrumented; instrument the service before dashboard authoring, then use ring:dev-implementation to verify observability checks pass" to user.
• If service has < 3 metric/trace/log emissions → STOP, surface "insufficient telemetry surface for dashboards".

Gate 1: Telemetry Sweep (7 Parallel Angles)

⛔ STOP-CHECK BEFORE DISPATCH

Before emitting any Task call, count the explorers you intend to launch in this turn.

• Count MUST equal 7.
• If count < 7 → STOP. Do not partial-dispatch. Reconcile against the 7 angles below and try again.
• The 7 angles are the canonical sweep. No substitutions, no omissions.

⛔ MUST NOT trickle-dispatch

All 7 explorers leave in the SAME TURN, before reading any explorer output.

Forbidden sequences:

• Dispatch explorer 1 → read result → dispatch explorer 2
• Dispatch a subset → wait → dispatch the rest
• Dispatch follow-up explorers conditioned on partial output
• Loop sequentially over the angle list

If you find yourself about to dispatch an explorer in a turn AFTER any explorer has already returned a result → STOP. You violated parallel dispatch. Report the violation and mark the gate INCOMPLETE rather than completing the trickle.

Self-verify after dispatch

After the dispatch turn, verify all 7 Task calls were emitted in that single turn. If fewer than 7 went out, the gate did NOT execute correctly. Mark INCOMPLETE and surface the dispatch failure — do NOT silently continue with a partial pool.

Parallel dispatch — atomic batch

Emit all 7 Task calls in a SINGLE TURN, as one atomic batch.

If your runtime exposes a multi_tool_use.parallel wrapper, use it to dispatch the complete pool in one wrapped invocation. This is the canonical fan-out mechanism on OpenAI-style tool envelopes and on certain Anthropic SDK consumers — naming it explicitly activates parallel emission on runtimes where trickle-dispatch is the default behavior.

If your runtime emits parallel tool_use blocks natively (Claude Code with Claude models), multi_tool_use.parallel may not be needed — but naming it is harmless and serves as an enforcement anchor.

The STOP-CHECK, anti-trickle, and self-verify guards above remain binding regardless of which mechanism your runtime uses.

Dispatch all 7 angles in one parallel batch. Wait for all before Gate 2.

Per-explorer dispatch (subagent_type: ring:codebase-explorer):

## Target: <absolute path>
## Your Angle: <angle number + name>
## Severity / Detection Patterns / Schema / Notes
<verbatim from sub-files/sweep-angles.md for this angle>

## Output
Write to: /tmp/dashboards-sweep-{N}-{angle-slug}.json
Schema: { angle_number, angle_name, primitives: [...] }
Each primitive includes file:line, name, description, labels/attributes, unit, type-specific fields.
If no findings: write file with empty primitives array.

The 7 angles cover:

1. Counter metrics — meter.Int64Counter, Float64Counter, increments, labels, descriptions, units
2. Histogram metrics — meter.Float64Histogram, Int64Histogram, boundaries, units, labels
3. Gauge metrics — meter.Int64UpDownCounter, Int64ObservableGauge, callbacks
4. Trace spans — tracer.Start, span names, kind, attributes, parent-child structure, error recording
5. Structured log fields — log.With, level usage, contexts where emitted, trace correlation
6. Cross-cutting concerns — tenant_id labeling, trace_id/span_id propagation, error attribution, request correlation
7. Framework instrumentation — Fiber/gRPC/RabbitMQ middleware, auto-spans, manual override sites

Full angle specifications: sub-files/sweep-angles.md.

Verification: 7 JSON files exist, all parse, schema-valid per sub-files/dictionary-schema.md.

HARD GATE: Missing/malformed file → re-dispatch ONLY failing angle.

Gate 2: Dictionary Assembly + Validation

Orchestrator merges 7 angle JSONs into /tmp/dashboards-dictionary.json. Validate per sub-files/dictionary-schema.md:

• Metric names match ^[a-z][a-z0-9_]*$ (Prometheus convention)
• Span names match ^[a-z][a-z0-9_.-]*$
• All primitives have description ≥ 30 chars
• Histograms declare unit (seconds, bytes, count) and boundaries if custom
• Tenant-scoped primitives have tenant_id in labels/attributes
• No duplicate (name, type) pairs across angle outputs
• Cross-cutting Angle 6 findings cross-reference primitives from Angles 1–4

Validation failures → re-dispatch failing angle's explorer with correction notes. Do NOT manually edit JSON.

Gate 3: Dictionary Rendering

Orchestrator writes docs/dashboards/telemetry-dictionary.md from validated JSON, following sub-files/dictionary-schema.md rendering contract:

• YAML frontmatter _meta block: service name, generated-at timestamp, source commit SHA, lib-commons version, primitive counts
• Metrics section: one ### {metric_name} per metric, with stable YAML block (type, unit, labels, description, emission_sites)
• Traces section: one ### {span_name} per span, with stable YAML block (kind, attributes, parents, emission_sites)
• Logs section: structured fields catalog with levels and emission contexts
• Cross-cutting section: tenant propagation map, trace correlation map, error attribution map

Critical: rendering MUST be deterministic — same input JSON produces byte-identical output. Order alphabetically within each section. Sort labels alphabetically within each primitive. This is what makes drift detection in Gate 7 possible.

Gate 4: Theme Proposal + Dashboard Plans

Orchestrator analyzes the dictionary and proposes themes + dashboards. This is the LLM-opinion gate — apply sub-files/reference.md (RED/USE methodology, panel pattern catalog) to dictionary contents.

For each proposed theme, produce a dashboard plan stub at /tmp/dashboards-plan-{theme}.md:

# Theme: {theme_name}

## Audience (proposed)
- Primary: <engineering | product | exec | ops | support>
- Secondary: <...>

## Dashboards
### {dashboard_1_name}
- Methodology: RED | USE | hybrid
- SLIs surfaced: <list>
- Time range default: <1h | 6h | 24h | 7d>
- Panels:
  1. {panel_name} — {panel_pattern} on metric {metric_ref} — Grafonnet template: {template}
  2. ...
- Alert candidates: <list with thresholds>

### {dashboard_2_name}
...

Themes are SUGGESTIONS only. PM may rename, merge, split, or reject in Gate 5.

Gate 5: PM Iteration — NEVER SKIPPABLE

Present sub-files/pm-iteration-prompts.md checklist to PM team:

• Theme names — accept, rename, merge, split?
• Audience per theme — correct?
• Methodology choice (RED vs USE vs hybrid) — sound for this domain?
• SLIs surfaced — match what stakeholders actually need?
• Time range defaults — match operational cadence?
• Alert thresholds vs informational — which panels need alerts attached?
• Missing dashboards — anything PM expected that wasn't proposed?

Response options:

• APPROVED: <theme1> <theme2> ... → proceed to Gate 6 for listed themes
• REVISE theme {name}: <change> → loops Gate 4 for that theme only
• RENAME theme {old} -> {new} → renames in plan, loops Gate 4 light
• REJECT theme {name} → drops from approval list
• ADD theme {name}: <description> → orchestrator generates new plan, loops Gate 4
• BLOCKED: <reason> → halts skill, returns with surface for triage

HARD GATE: Must not proceed to Gate 6 without explicit APPROVED: ... listing at least one theme.

Gate 6: Grafonnet Authoring (Per Approved Theme)

For EACH approved theme, dispatch ring:backend-engineer-golang (Lerian's Go specialist; Grafonnet is jsonnet, but the engineer's discipline around code quality and reusability transfers — and they own the lib-commons mental model that makes label correctness checkable).

Per-theme dispatch:

## Target: docs/dashboards/{theme}/
## Inputs:
- /tmp/dashboards-plan-{theme}.md (PM-approved plan)
- docs/dashboards/telemetry-dictionary.md (canonical primitive contract)
- pm-team/skills/creating-grafana-dashboards/sub-files/grafonnet-templates/ (panel libsonnet templates)
- pm-team/skills/creating-grafana-dashboards/sub-files/reference.md (panel pattern → template mapping)

## Task:
1. Create docs/dashboards/{theme}/ directory
2. Write {theme}.libsonnet importing relevant grafonnet-templates panels
3. Materialize each panel from the plan with concrete metric refs from the dictionary
4. Compose into a Dashboard with rows/grid per plan structure
5. Write README.md per theme explaining: audience, SLIs, intended use, alert thresholds
6. Validate: jsonnet compiles cleanly, panel queries reference only primitives present in dictionary

## Output:
- docs/dashboards/{theme}/{theme}.libsonnet
- docs/dashboards/{theme}/README.md
- /tmp/dashboards-build-{theme}.log (compilation output)

## Constraints:
- MUST NOT invent metric names — every PromQL/LogQL/TraceQL query references primitives from telemetry-dictionary.md
- MUST template tenant_id as a Grafana variable when present in primitive labels
- MUST follow Grafonnet conventions (no raw JSON; if a panel pattern isn't in templates/, propose a new template)

Verification: Per theme — libsonnet compiles to JSON, README present, no metric references missing from dictionary.

HARD GATE: Compilation failure → re-dispatch with diagnostic, do not move to Gate 7.

Gate 7: CI Drift Gate Setup

Orchestrator installs (idempotent) the drift detection workflow per sub-files/ci-drift-check.md:

1. Write .github/workflows/telemetry-drift.yml (blocking PR check)
2. Write scripts/regenerate-telemetry-dictionary.sh (regenerates dictionary; called by CI and locally)
3. Update Makefile: add make telemetry-dictionary target invoking the regenerate script
4. Compile all theme libsonnet to JSON in docs/dashboards/{theme}/{theme}.json and add to .gitignore (build artifact)
5. Surface to user: workflow path, local regen command, expected first-CI-run behavior

Idempotence: If .github/workflows/telemetry-drift.yml already exists, diff against canonical version. Update only if drift detected. Surface diff to user before overwriting.
