Pydantic Logfire × Metabase

How to build Pydantic Logfire dashboards in Metabase

Pydantic Logfire is an observability platform from the Pydantic team for traces, logs, and metrics — with first-class Python and LLM-app instrumentation and SQL-native querying. Metabase is where you turn those operational signals into shared, trustworthy dashboards. This guide covers two complementary paths: a lightweight MCP + CLI route that pulls live data with the Logfire MCP server and loads a CSV into Metabase with the Metabase CLI, and a durable pipeline route that syncs Pydantic Logfire rollups into a database so you can build dashboards anyone can read.

Heads up: Metabase connects to databases and warehouses — it does not ship a native Pydantic Logfire connector, and a BI warehouse is the wrong home for raw telemetry. Sync aggregates, entities, and metadata — incidents, error groups, rollups, deploys — and leave the event firehose in Pydantic Logfire.

How do you connect Pydantic Logfire to Metabase?

Most teams combine both routes: use MCP and CLI uploads for a fast first pass, then move recurring reliability reporting to a warehouse-backed model.

1 · MCP + CLI route (AI-assisted)

Live data in, quick analysis out

Pair the Logfire MCP server with the Metabase CLI. Use MCP for live lookups, write a scoped result to CSV, then load it into Metabase as a ready-to-query table and model.

Best for
  • Quick lookups such as "show me trace volume and latency by service"
  • Loading a Pydantic Logfire export into Metabase in seconds
  • Spot-checks and one-off analyses without a warehouse
Trade-offs
  • Great for exploration, not governed reliability reporting
  • Use read-only/scoped credentials wherever the MCP server supports them
  • CSV uploads are snapshots — refresh or move to the pipeline for history
2 · Pipeline route (warehouse-backed)

Durable dashboards with history

Sync Pydantic Logfire rollups and metadata into a database or warehouse with a connector, custom pipeline, or API, then point Metabase at it.

Best for
  • Pydantic Logfire reliability dashboards leaders depend on
  • Joining Pydantic Logfire data with deploys, issues, support, or cost data
  • Long-run trends for trace volume and latency by service and exception trends
Trade-offs
  • You own the refresh schedule and the rollup grain
  • Sync aggregates and entities — not the raw event firehose
  • Metric definitions must be consistent across services and teams

What can you analyze from Pydantic Logfire data in Metabase?

  • Trace volume and latency by service — built from span and trace rollups and the related exceptions, metrics, LLM call summaries data your sync exposes.
  • Exception trends — built from span and trace rollups and the related exceptions, metrics, LLM call summaries data your sync exposes.
  • LLM call cost and token usage — built from span and trace rollups and the related exceptions, metrics, LLM call summaries data your sync exposes.
  • Slowest operations — built from span and trace rollups and the related exceptions, metrics, LLM call summaries data your sync exposes.
  • Service health rollups — built from span and trace rollups and the related exceptions, metrics, LLM call summaries data your sync exposes.

How do you use the Logfire MCP server with the Metabase CLI?

Pair the Logfire MCP server with the Metabase CLI for fast, hands-on analysis. MCP is useful for scoped lookups and summarized exports; the Metabase CLI's upload command loads CSV data into Metabase and creates a ready-to-query table and model.

Example workflow

  • Ask the MCP server for a summarized slice of span and trace rollups for the services you care about.
  • Export the result as CSV, keeping stable IDs, services, environments, severities, and timestamps.
  • Run mb upload csv to load it into Metabase as a table and model, then build questions and dashboards on top.

Be honest about the limits

  • MCP lookups are excellent for exploration, not scheduled reporting.
  • A CSV upload is a snapshot; refresh it with mb upload replace or move to the pipeline for real history.
  • Periodic rollups (hourly or daily) are required for availability and error-rate trends.
  • mb upload csv needs an uploads database configured under Admin → Settings → Uploads.

Can you generate a Pydantic Logfire dashboard with AI?

Yes. Use the prompt below with any assistant that can run the Logfire MCP server and the Metabase CLI. It works end to end: if Pydantic Logfire tables already exist in Metabase it analyzes those; otherwise it pulls scoped, summarized data over MCP, loads it with mb upload csv, then builds the dashboard and caveats any metric that needs missing history.

Prompt for creating a Pydantic Logfire Observability Overview dashboard
Create a polished Metabase dashboard for Pydantic Logfire observability analytics.
Work end to end: get the data into Metabase if it isn't there yet, then build.

Goal: Help engineering and operations leaders understand service availability, error rates, alert quality, and SLO compliance from Pydantic Logfire data.

Step 1 — Find or load the data:
- First, check what already exists in Metabase (search for logfire tables and
  models). If durable Pydantic Logfire data is already present — synced from a warehouse
  or uploaded earlier — use it and skip to Step 2.
- If nothing is there, pull a scoped, summarized export with the Logfire MCP server:
  span and trace rollups, plus exceptions, metrics, LLM call summaries.
  Prefer aggregated or rollup views over raw events. Write each result to a CSV,
  then load it with the Metabase CLI — run "mb upload csv --file <export>.csv" so
  each upload creates a table and a ready-to-query model. Use "mb upload replace
  <table-id> --file <export>.csv" to refresh an existing table instead of creating
  duplicates.

Step 2 — Inspect before querying:
Do not assume exact table or column names. Inspect available fields, services,
environments, timestamps, and whether rollups or history exist before creating
duration or trend cards.

Important:
- Build on whatever data is present; don't claim Metabase connects natively to
  Pydantic Logfire — it reads a database or CLI-uploaded tables.
- Never try to load the raw event firehose into Metabase; use rollups, entity
  tables, and incident- or group-grain data.
- Only compute durations (MTTA, MTTR, time-to-resolve) when the required
  timestamps exist.
- Exclude test, staging, or muted objects from headline reliability cards, and
  segment by environment where the field exists.
- A single CSV is a point-in-time snapshot: only build trend cards if there is a
  usable date column or multiple periods have been uploaded.

Dashboard title: Pydantic Logfire Observability Overview

Sections:
1. Executive summary: Availability last 30 days; Error rate; Alerts fired;
   SLO compliance; Services below target.
2. Service health: Availability and error rate by service by week.
3. Alerts: Alert volume by monitor; conversion to incidents; noisy monitors.
4. SLOs: Error budget remaining; burn rate; breaches by service.
5. Trends: Latency percentiles and traffic by service where synced.

Filters: Date range, Service, Environment, Severity, Team, Status.

Output: Build the dashboard if you have permission; otherwise provide the exact
questions, SQL, model definitions, and layout. Include caveats for any metric
that cannot be calculated from the available data.

How do you sync Pydantic Logfire data into a database or warehouse?

For dashboards that need history and reliability, land Pydantic Logfire rollups and metadata in a database first, then connect Metabase to that database.

Connector options

  • Managed ETL — use a connector when one covers the objects you need.
  • Custom pipeline — use the Logfire Query API for control over rollup grain, fields, and refresh cadence.
  • MCP + CSV — use this for quick exploration and one-off slices.

No managed connector exists — and none is needed for rollups: the Logfire Query API runs arbitrary SQL over your telemetry (POST /v2/query) and returns JSON, Arrow, or CSV, so a scheduled script lands exactly the aggregates you want.

Notes

  • Decide the rollup grain first (hourly or daily per service/environment) — it drives warehouse cost and every trend card.
  • Land raw entity tables first, then build clean Metabase models on top.
  • Normalize service, environment, metric, window-start, and aggregation fields.

How should you model Pydantic Logfire data in Metabase?

Core tables

TableGrainKey columns
service_health_rollupsone row per service per hour or dayservice_name, environment, window_start, total_requests, successful_requests, p95_latency_ms
logfire_span_rollupsone row per operation per hourservice_name, span_name, window_start, span_count, error_count, p95_duration_ms
logfire_exception_rollupsone row per exception type per dayservice_name, exception_type, window_start, event_count, first_seen_at

Modeling advice

  • Build a clean service_health_rollups model with common columns across tools, so multi-source dashboards don't fork definitions.
  • Separate entity tables (services, monitors, policies) from time-series rollups and event-grain tables.
  • Exclude test, staging, and muted objects from headline reliability metrics; keep environment as an explicit column.
  • Use stable IDs for service, team, and incident joins; display names change.

Which Pydantic Logfire metrics should you track in Metabase?

MetricDefinitionNotes
Service availabilitySuccessful requests or minutes divided by total, per service.Define success once (status < 500, or probe-based).
Error rateError events divided by total requests per window.Use rollups; raw events don't belong in a warehouse.
Alert noise rateAlerts that led nowhere divided by all alerts fired.Review the noisiest monitors monthly.
SLO complianceActual reliability against the SLO target and error budget.Burn rate matters more than a point-in-time number.

What SQL powers Pydantic Logfire dashboards in Metabase?

These assume a cleaned analytical model in a warehouse (PostgreSQL dialect). Adjust table and column names to match your pipeline.

Availability by service by weekPostgreSQL

From success/total rollups per service.

SELECT
  service_name,
  date_trunc('week', window_start) AS week,
  ROUND(
    100.0 * SUM(successful_requests) / NULLIF(SUM(total_requests), 0), 3
  ) AS availability_pct
FROM service_health_rollups
WHERE environment = 'production'
GROUP BY 1, 2
ORDER BY 1, 2;
Alert volume and conversion by monitorPostgreSQL

Which monitors page for real problems.

SELECT
  monitor_name,
  COUNT(*) AS alerts_fired,
  COUNT(*) FILTER (WHERE became_incident) AS incidents,
  ROUND(
    100.0 * COUNT(*) FILTER (WHERE became_incident)
    / NULLIF(COUNT(*), 0), 1
  ) AS conversion_rate
FROM alerts
WHERE fired_at >= CURRENT_DATE - INTERVAL '30 days'
GROUP BY monitor_name
ORDER BY alerts_fired DESC
LIMIT 20;
SLO compliance and marginPostgreSQL

Actual reliability vs. the published target, trailing 28 days.

SELECT
  service_name,
  slo_target,
  ROUND(
    100.0 * SUM(successful_requests) / NULLIF(SUM(total_requests), 0), 3
  ) AS actual,
  ROUND(
    100.0 * SUM(successful_requests) / NULLIF(SUM(total_requests), 0), 3
  ) - slo_target AS margin
FROM service_health_rollups
WHERE window_start >= CURRENT_DATE - INTERVAL '28 days'
GROUP BY service_name, slo_target
ORDER BY margin ASC;

What are common mistakes when analyzing Pydantic Logfire in Metabase?

Syncing the raw event firehose into the warehouse.→ Land rollups, entities, and incident- or group-grain tables. Raw telemetry belongs in Pydantic Logfire; the warehouse is for trends and joins.
Averaging availability across services.→ A 99.99% service and a 97% service don't average into anything meaningful. Report per service against its own target.
Reporting latency as an average.→ Use p50/p95/p99 from pre-aggregated percentile rollups; means hide tail pain, and percentiles can't be re-averaged later.
Building dashboards from live MCP lookups only.→ MCP is useful for exploration; durable dashboards need a database-backed model with history.

FAQ

Does Metabase connect natively to Pydantic Logfire?
No. Metabase reads databases and warehouses. Sync Pydantic Logfire rollups and metadata into a database first, or upload a CSV with the Metabase CLI, then build Metabase models and dashboards on top.
Should Metabase replace Pydantic Logfire?
No — they answer different questions. Pydantic Logfire is built for real-time triage and deep debugging. Metabase is where you build governed, shareable reporting on top of the same signals, and join them with deploys, issues, support, and business data.
How much telemetry should I sync into the warehouse?
As little as answers the question: hourly or daily rollups per service and environment, alert and monitor metadata, and SLO definitions. Keep raw metrics, logs, and traces in the observability stack and link out for drill-downs.
How is this different from the dashboards I already have?
Native dashboards are excellent for operators. Metabase adds governed definitions, org-wide sharing without per-seat operator licenses, and joins with business data — reliability next to revenue, incidents next to releases.
