Umbral Analytics

You can't improve what you can't see. Umbral Analytics auto-captures pageviews and lets you fire custom product events to PostHog, so "which features do people actually use?" stops being a guess. The outbound sends are bounded — an analytics burst can't fan out unbounded connections and take the request path down with it — so instrumenting your app never becomes the reason it falls over.

Install

cargo add umbral-analytics

Wire it up

Read the key from the environment and exclude paths you don't want counted.

use umbral::prelude::*;
use umbral_analytics::AnalyticsPlugin;

let app = App::builder()
    .database("default", pool)
    .plugin(
        AnalyticsPlugin::from_env()                  // UMBRAL_ANALYTICS_* keys
            .with_exclude_prefixes(vec!["/static".into(), "/healthz".into()]),
    )
    .build()?;

Target: track a conversion, not just a pageview

Auto-capture gives you traffic; a custom event gives you the funnel step that matters.

What you get

• Auto-captured pageviews to PostHog
• Custom product events for the funnel steps you care about
• Path-prefix exclusions (skip /static, health checks, etc.)
• Bounded outbound sends — a burst can't exhaust connections
• Key from env via from_env(), or explicit with new(api_key)
