# Dashboard Ops > Deployment and runtime internals for dashboard email reports and analytics alert rules: server-side SVG/PNG report rendering, serverless timing budgets, cron wiring, and notification delivery env vars. Use when configuring, deploying, or debugging report/alert delivery infrastructure — not when just creating a report subscription or alert rule via the action surface. - Skill: `builderio/dashboard-ops` (Agent Skill) - Install (CLI): `npx skillmds@latest add builderio/dashboard-ops` - Raw SKILL.md: https://api.skillmd.com/api/skills/builderio/dashboard-ops/raw - Safety review: pending - Works with: Claude Code, Claude.ai, OpenAI Codex - Category: DevOps & Infra - Author: Builder.io (https://skillmd.com/u/builderio) - Updated: 2026-09-17 - Page: https://skillmd.com/skills/builderio/dashboard-ops --- # Dashboard Reports & Alerts Ops Dashboard email reports (`dashboard-report-subscriptions` actions) and analytics alert rules (`analytics-alert-rules` actions) are SQL-backed action surfaces. This skill covers the deployment/runtime machinery behind them — the agent chatting with an end user does not need this; it only needs the action names and the user-facing constraints already in `AGENTS.md`. ## Dashboard Email Report Rendering - Scheduled reports render entirely server-side. They do not use a headless browser, Chromium pack download, or the old `reportScreenshot=1` embed-session screenshot URL; interactive dashboard screenshot capture remains separate. - Each panel's query runs through the same source dispatcher the UI uses (`runDashboardPanelQuery`), inside the subscription owner's request context, so per-source access scoping (BigQuery/Gong/HubSpot credentials, org scoping) is preserved exactly as if the owner loaded the dashboard. - Chart panels are drawn as SVG and rasterized to PNG with `@resvg/resvg-js`, then embedded in the email as `cid:` attachments. Fonts come from `resolveOgFontFiles()` — **resvg has no system fonts in a Lambda runtime, so chart text silently renders blank (not an error) unless those bundled font files are passed to it.** Never drop that font wiring when touching chart rendering. - Non-chart panels (`section`, `metric`, `callout`, `table`, `heatmap`) render as real email HTML, not images. `extension` panels cannot be rendered for email at all and instead link out to the live dashboard. - A panel that fails to query renders a visible error card in its place and marks the whole run `degraded`; a degraded report is never sent or recorded as if it were complete. If every panel fails, nothing is sent and the subscription errors out instead of emailing an empty report. - Subscriptions are capped at five distinct recipients (`MAX_DASHBOARD_REPORT_RECIPIENTS`) — recommend a mailing-list address for larger audiences. - The ten-minute retry delay is an eligibility floor, not a guarantee; the `*/15` sweep runs the retry on its first tick after that floor. - The serverless delivery deadline (`SERVERLESS_REPORT_DELIVERY_BUDGET_MS` in `server/jobs/dashboard-report.ts`) reserves 220 seconds of the `dashboard-report-sweep-background` function's 300-second `netlify.toml` timeout for rendering and delivery, leaving the remainder for cleanup. - Netlify processes one subscription per background invocation so every report gets a fresh delivery deadline and first-party queries cannot contend with another report. When due work remains, the worker queues another background invocation immediately and drains the batch sequentially. Long-lived (non-Netlify) runtimes default to a limit of 5, overridable with `DASHBOARD_REPORT_SWEEP_LIMIT`. ### Env Vars - `DASHBOARD_REPORT_BASE_URL` — overrides the dashboard link URL in emails; if unset, falls back to `getAppProductionUrl()` (the `APP_URL` / `WORKSPACE_OAUTH_ORIGIN` / `BETTER_AUTH_URL` chain). - `RESEND_API_KEY` or `SENDGRID_API_KEY` plus `EMAIL_FROM` — required to send the report email at all. - `DASHBOARD_REPORTS_CRON_SECRET` — bearer token external cron callers must send to `POST /api/dashboard-reports/run`. - `DASHBOARD_REPORT_SWEEP_LIMIT` — overrides the per-tick sweep size on non-Netlify runtimes (see above). ## Cron Wiring - Netlify builds emit a scheduled trigger plus a background worker from `scripts/emit-netlify-dashboard-report-cron.ts`, using a per-deploy internal token and disabling the in-process interval scheduler on Netlify to avoid duplicate sends. - External cron callers can sweep due reports by POSTing `/api/dashboard-reports/run` with `Authorization: Bearer $DASHBOARD_REPORTS_CRON_SECRET`. - The same `scripts/emit-netlify-dashboard-report-cron.ts` script also emits the alert-rule cron trigger plus background worker, running every five minutes on Netlify. Long-lived runtimes use the in-process scheduler unless `ANALYTICS_ALERT_JOBS=0` is set. - External cron callers can run due alerts by POSTing `/api/analytics-alerts/run` with `Authorization: Bearer $ANALYTICS_ALERTS_CRON_SECRET`. ## Alert Notification Delivery Alert notifications use the shared notification channel registry (`channels` can include `inbox`, `email`, `slack`, `webhook`, or any custom registered channel): - Slack/webhook delivery prefers per-rule `metadata.delivery.slackWebhookUrl` / `metadata.delivery.webhookUrl` (uptime monitors store these on the monitor row), then falls back to `NOTIFICATIONS_SLACK_WEBHOOK_URL` / `NOTIFICATIONS_WEBHOOK_URL`. Optional `NOTIFICATIONS_SLACK_WEBHOOK_AUTH` configures Slack auth. - Email delivery needs `RESEND_API_KEY` or `SENDGRID_API_KEY` plus `EMAIL_FROM`. Per-rule `emailRecipients` fall back to `NOTIFICATIONS_EMAIL_RECIPIENTS`. Saving explicit `emailRecipients` also remembers them as the current user's defaults for the next alert rule created in Settings. Users can also view and manage report subscriptions and alert rules in Settings; that UI uses the same action surface as the agent, so no separate implementation is needed there. ## Related Skills - **dashboard-management** — the dashboard artifact model these features attach to. - **integration-webhooks** (root) — the general queue-and-processor pattern for outbound webhook delivery.
