Dashboard Explain

Prerequisites

This skill calls SigNoz MCP server tools (signoz:signoz_get_dashboard, signoz:signoz_list_dashboards). Before running the workflow, confirm the signoz:signoz_* tools are available. If they are not, the SigNoz MCP server is not installed or configured — run signoz-mcp-setup first to initialize or repair the MCP connection. Do not guess at a dashboard’s contents from its title alone.

When to use

Use this skill when the user asks to:

• Understand, explain, or interpret an existing dashboard
• Get a walkthrough of what panels show and why they matter
• Know what to watch for or what healthy/unhealthy looks like on a dashboard
• Understand the variables, filters, or queries on a dashboard

Do NOT use when:

• User wants to modify an existing dashboard → signoz-modifying-dashboards

Instructions

Step 1: Identify the target dashboard

Determine which dashboard the user wants explained. If the user provides a dashboard name, UUID, or it is clear from context (e.g., an @mention or auto-context providing a dashboard resource), use that.

If the target dashboard is ambiguous:

1. Call signoz:signoz_list_dashboards to list existing dashboards. Paginate through all pages — check pagination.hasMore in the response. If hasMore is true, call again with offset set to pagination.nextOffset and repeat until all pages are exhausted. Never stop at the first page.
2. Present matching candidates to the user and ask which one to explain.

Step 2: Fetch the full dashboard configuration

Call signoz:signoz_get_dashboard with the dashboard UUID. This is mandatory — you need the complete JSON to explain the dashboard accurately. Never guess based on the title alone.

Examine the response to understand:

• title, description, tags — the dashboard identity and author-provided context
• variables — dashboard-level filters (dropdowns the user can change)
• widgets — the panels, their types, titles, and queries
• layout — how panels are arranged in the 12-column grid
• panelMap — which panels belong to which row sections

Step 3: Build the explanation

Structure your explanation in this order:

1. Overview — One paragraph summarizing the dashboard’s purpose, what it monitors, and what data sources it draws from (metrics, traces, logs). Mention the tags if they provide useful context.

2. Variables and filters — Explain each variable:

• Name and what it filters (e.g., “The service_name variable filters all panels to a specific service”)
• Type: DYNAMIC (auto-populated from telemetry), QUERY (SQL-driven dropdown), or TEXTBOX (free-form input)
• Whether it supports multi-select and has “ALL” option
• Note if any panels do NOT reference a variable in their filters — changing that variable dropdown would not affect those panels, which can be confusing

3. Panel-by-panel walkthrough — Group panels by their row sections using the panelMap structure (row widget titles are the section headers). If the dashboard has no rows (empty panelMap), walk through panels in layout order (by y then x position) and organize by logical theme. For each panel:

• Title and panel type (graph, value, table, bar, pie, histogram, list)
• What it shows — interpret the query in plain language. For builder queries, explain the metric/data source, aggregation, filters, and groupBy. For formulas, explain each sub-query and how the formula combines them. For ClickHouse SQL or PromQL, translate the query intent into plain English.
• What to watch for — describe what healthy looks like and what patterns indicate trouble. Be specific: “sustained usage above 80% means…” not just “watch if it’s high”. Anchor advice to the actual metric being queried, not generic domain knowledge.
• Unit — mention the y-axis unit so the user knows how to read the values

For panels with complex queries:

• Formulas (queryFormulas): explain each sub-query (A, B, …) separately, then explain what the formula computes and why
• Multiple queries on one panel: explain each query and how they relate
• Functions (rate, derivative, clampMin/Max, timeShift): explain the transform in plain terms (e.g., “rate converts the raw counter into a per-second value”)

4. Dashboard health observations — After the walkthrough, note any structural issues you spotted:

• Panels with no queries or empty/disabled queries
• Variables defined but not referenced in any panel filter
• Panels missing thresholds where they would be useful (e.g., utilization panels without a saturation warning line)
• Counters displayed without a rate function (raw counters produce ever-increasing ramps, not operational rates)
• Very wide step intervals that could hide spikes
• Panels with high-cardinality groupBy that may produce unreadable charts

5. Coverage gaps — Based on what the dashboard actually monitors, note significant observability areas that are absent. Only mention gaps that are directly related to the technology or domain the dashboard covers — do not speculate about unrelated areas. Frame as suggestions: “You may want to consider adding panels for X to cover Y.”

Step 4: Offer next steps

Surface up to 3 follow-up intents based on what the explanation surfaced — things like running a specific panel’s underlying query, filling a coverage gap, or wiring an alert for an actionable threshold the user has not yet alerted on. Use your judgment; do not pad to 3.

Skip follow-ups when the user was clearly just onboarding to the dashboard (“what is this?”) and showed no further intent. No chips beat wrong chips.

Guardrails

• Fetch before explaining: Always call signoz:signoz_get_dashboard to get the full configuration. Never explain based on the dashboard title or listing alone.
• Interpret, don’t dump: Translate queries into plain operational language. Never show raw query JSON to the user unless they specifically ask.
• Anchor to actual content: Base “what to watch for” advice on the actual metrics and queries in the dashboard, not on generic domain knowledge unrelated to the panels present.
• Group by sections: Use the panelMap row structure to group panels, not layout coordinates. The row titles are the section headers the dashboard author intended.
• No data queries by default: Do not run live queries unless the user asks. The explain skill is about understanding the dashboard structure, not inspecting current data.
• Paginate dashboard listing: When searching for a dashboard by name, always paginate through all pages of signoz:signoz_list_dashboards before concluding a dashboard does not exist.
• All query types: Handle builder, ClickHouse SQL, and PromQL queries — each requires a different interpretation approach. For builder queries, read the aggregations, filter expression, and groupBy. For raw SQL/PromQL, parse the query string and explain the intent.
• Scope boundary: This skill explains dashboards. If the user wants to change something after your explanation, redirect to signoz-modifying-dashboards.

Examples

User: “Explain my PostgreSQL dashboard”

Agent:

1. Calls signoz:signoz_list_dashboards (paginates all pages) — finds “PostgreSQL Overview” dashboard with UUID abc-123.
2. Calls signoz:signoz_get_dashboard with UUID abc-123 — gets full configuration.
3. Provides structured explanation:
   • Overview: “This dashboard monitors PostgreSQL database health across connections, query performance, buffer cache efficiency, and replication. It uses metrics from the OpenTelemetry PostgreSQL receiver.”
   • Variables: “Two variables — host_name (DYNAMIC, filters by host.name) and database (DYNAMIC, filters by postgresql.database.name). Both support multi-select.”
   • Panels by section: Walks through each row section, explaining every panel’s metric, aggregation, and what to watch for.
   • Health observations: “The ‘Connection Count’ panel has no threshold configured — consider adding a line at 80% of your max_connections.”
   • Coverage gaps: “No panels for vacuum/autovacuum health or lock contention. Consider adding these if you manage write-heavy workloads.”
4. Offers: “Want me to run any panel queries to check for data, or add the suggested panels?”

User: “What does each panel on this dashboard show?” (with dashboard context provided via @mention or auto-context)

Agent:

1. Extracts dashboard UUID from the provided context.
2. Calls signoz:signoz_get_dashboard — gets full configuration.
3. Provides a focused panel-by-panel walkthrough grouped by row sections, explaining what each panel shows and what to watch for.
4. Skips the health/gaps sections unless something notable stands out, since the user asked specifically about panels.

User: “Help me understand this LLM monitoring dashboard — I’m new to it”

Agent:

1. Identifies the dashboard, fetches full config.
2. Provides a beginner-friendly explanation with more context per panel:
   • Explains what the metrics mean (e.g., “Token usage measures how many tokens your LLM calls consume, which directly impacts cost”)
   • Explains what the variables control and recommends starting with the “ALL” option to see the full picture before filtering
   • Highlights the most important panels to watch daily vs. those useful only during debugging
3. Offers to set up alerts on critical panels.
