Skill v1.0.0

version: "1.0.0" name: dba-dashboard description: Use when asked to build a Teradata system health/status dashboard for a DBA — space usage, resource consumption, flow control, and session activity. Calls the teradata-mcp-server dba_ and base_ tools and renders the results as a single dashboard (HTML artifact, markdown report, or chat response, depending on what the client supports).

You are building a Teradata system health dashboard for a DBA audience, using the tools exposed by a connected teradata-mcp-server (profile must include the dba_ and base_ tool prefixes — e.g. --profile dba or --profile all).

Workflow

Work through the phases below in order. Each phase is one or two tool calls — do not iterate per day or per database unless a step says to.

Phase 1 — Inventory and space

1. base_databaseList(scope="user") — or scope="all" if the DBA wants system databases included too. Use the result as the list of databases for later phases.
2. dba_systemSpace() — total space used/allocated/free across the whole system.
3. dba_tableSpace(database_name=..., top_n=10, exclude_system="Y") for the database(s) in scope — largest tables and how full they are.
4. dba_databaseSpace(database_name=...) per database in scope — allocated vs. used vs. free space.

dba_databaseSpace, dba_tableSpace, and dba_tableUsageImpact all require a non-empty database_name. If the DBA didn't name one, iterate the list from step 1 rather than passing an empty string.

Phase 2 — Resource usage (CPU / IO / memory)

dba_resusageSummary(no_days=30) returns one row per LogDate × hourOfDay × dayOfWeek × workloadType × workloadComplexity × UserName × AppID already grouped — a single call gives the full 30-day breakdown needed for both a daily trend and an hour-of-day heatmap. Don't call it once per dimension or once per day.

Use workloadType/workloadComplexity filters only if the DBA wants to drill into one slice (e.g. workloadType="Batch").

Phase 3 — Flow control and queueing

dba_flowControl and dba_userDelay take explicit start_date/end_date (YYYY-MM-DD), not a day count. Compute the range yourself (e.g. today minus 30 days) and call each once:

1. dba_flowControl(start_date=..., end_date=...) — when and how much the workload manager throttled queries.
2. dba_userDelay(start_date=..., end_date=...) — how long users personally waited in queue before their queries started.

Phase 4 — Sessions and activity

1. dba_sessionInfo(user_name="*") — currently active sessions across all users.
2. base_tableUsage(database_name=...) per database in scope — which tables are hottest and who's hitting them.

Phase 5 — Optional context

• dba_databaseVersion() — software version, useful in the dashboard header.
• dba_featureUsage(start_date=..., end_date=...) — which product features were exercised in the period, if the DBA cares about feature adoption.

Rendering the dashboard

Structure the output as:

1. Executive summary — system version, total space used/allocated/free, number of databases and tables in scope, headline resource trend, any critical alerts.
2. Space — system-wide totals, per-database breakdown, top space-consuming tables. Color-code utilization: red ≥ 85%, yellow 70–85%, green < 70%.
3. Resource usage — CPU/IO/memory trend by day, plus an hour-of-day × day heatmap from the Phase 2 data.
4. Flow control & delay — throttling events and queue wait times from Phase 3, called out as bottlenecks if delay times are material.
5. Sessions & activity — active sessions and the busiest tables/users from Phase 4.

If the client can render an HTML artifact, build the dashboard as a single self-contained page (see the dataviz skill for chart/color guidance if available) so it's easy to skim. Otherwise, present the same structure as markdown with tables and a short narrative per section — don't skip sections just because charts aren't available.

Gotchas

• Never call dba_databaseSpace, dba_tableSpace, or dba_tableUsageImpact with an empty database_name — ask which database, or iterate the list from base_databaseList.
• dba_flowControl and dba_userDelay want computed start_date/end_date, not a no_days count like dba_resusageSummary — don't mix the two calling conventions up.
• base_databaseList defaults to scope="user" (excludes system databases); pass scope="all" explicitly if the DBA wants system databases in the picture.
• To hand a metric to the plot_* tools (plot_line_chart, plot_pie_chart, ...), materialize it first by calling the source tool with persist=true, then pass the returned table name — the plot tools read from a table, not from raw query results.
