Monitoring Plan

Context

This feature is a static marketing website (dist/ bundle, no back-end, no database) currently deployed manually via a build artifact (see operations/deployment/deployment-plan.md). There is no existing monitoring/logging infrastructure in this project yet.

Decision

Monitoring/observability is included for this feature (Question 1 = A / clarified further via Clarification Question 1).

Initial answers to the monitoring plan were contradictory: Question 2 selected "Logging" only (A), yet the alerting/dashboard follow-up questions (4, 5, 6) were also answered, and the answer to Question 4 (S) was not a valid option. A clarification round was run (operations/plans/monitoring-setup-clarification-questions.md) to resolve this before generating artifacts.

Clarified answer: Logging + Dashboards (Clarification Question 1 = C). Alerting is explicitly out of scope for this feature at this time (Clarification Question 2 = D, "not needed yet / decide later" — consistent with not choosing Alerting in Clarification Question 1).

Chosen Approach(es)

Logging

Client-side errors (JavaScript crashes, broken links) should be logged, but the concrete destination is not yet decided (original Question 3 = C, "not yet determined"). This is tracked as an open action item below rather than blocking this stage.

Dashboards

A combination of:

• Website analytics: decided — self-hosted Umami (Podman on the webserver Pi, see operations/monitoring/umami-setup.md), chosen over GA4/hosted Plausible for privacy-friendliness and no recurring cost.
• Uptime dashboard: decided — UptimeRobot, chosen over Better Uptime for its established free tier.

(Original Question 6 = C, "Both (analytics + uptime dashboard)".)

Explicitly Out of Scope

• Alerting/notifications: not requested. If the uptime dashboard tool supports basic notifications (e.g. UptimeRobot's own e-mail alert on downtime), that MAY be enabled opportunistically as part of dashboard setup, but no dedicated alerting channel, escalation policy, or alert-on-error-rate logic is designed or required here.
• Reuse of existing infrastructure: this feature does not plug into any pre-existing shared monitoring (original Question 7 = A) — there is none yet. Should a shared back-end/CMS monitoring stack be introduced later, this can be revisited.

Open Action Items

1. Decide logging destination: choose between "browser console only" (no central storage, manual debugging) or a free/low-cost external error-tracking service (e.g. Sentry free tier) once this becomes a priority. Until decided, monitoring-setup.md documents both options so either can be adopted without re-doing this stage.
2. Pick concrete analytics + uptime tools — Resolved: self-hosted Umami + UptimeRobot (see monitoring-setup.md and umami-setup.md). Remaining manual follow-ups: actually deploying the Umami containers on the Pi, registering DNS/SSL for analytics.slpsoftware.nl, creating the UptimeRobot monitor, and setting the VITE_UMAMI_SCRIPT_URL/VITE_UMAMI_WEBSITE_ID Gitea repository variables.

Rationale

Given this is a simple static marketing site with no backend and no existing monitoring, the aim is lightweight, low/no-cost observability: enough to know if the site is down (uptime) and how it's being used (analytics), plus a documented (if not yet finalized) path for capturing client-side errors. Alerting was deliberately left out to avoid over-engineering a notification pipeline before there's a concrete trigger/audience for it.
