What is Magento monitoring?
Magento monitoring is the practice of continuously checking that a Magento store is not just online but actually working for shoppers — that category pages have products, search returns results, checkout completes, and background jobs (cron, indexers, queues) are keeping up. The hard part is that most Magento failures still return HTTP 200, so a generic uptime monitor reports the store as healthy while customers can't buy.
Pulsar covers this in two layers. From outside, global probes run sub-minute HTTP checks and a real Chromium browser walks the full Product → Cart → Checkout flow (with Luma and Hyvä presets) to catch front-end and payment regressions. From inside, an optional read-only Magento extension exposes 20 health collectors — indexer drift, cron heartbeat, queue backlog, OpenSearch cluster state, Redis evictions, PHP-FPM saturation, stuck pending_payment orders, SSL expiry, admin 2FA gaps, and more — surfacing internal state nothing external can see. Alerts route to Slack, Discord, email, or PagerDuty with per-collector noise controls.
HTTP 200 is the most expensive false positive in commerce
Generic uptime tools watch status codes. Pulsar watches whether customers can actually buy — and maps every failure mode to a specific Magento collector or browser signal.
Silent-Failure Detection
Most outages return HTTP 200. Empty categories from a drifted indexer, cron processes that died at 3 a.m., add-to-cart buttons broken by a JS error, zero-result searches from a red OpenSearch cluster — Pulsar maps each scenario to a specific collector and flags it the moment it starts. The thing Pingdom and Uptime Robot can't see is the thing Pulsar is built to catch.
External Synthetic Uptime
Sub-minute HTTP checks from global probes — works with any commerce platform, runs from outside your firewall so we don't go dark when your server does. Response times, status codes, SSL expiry, content substring matching, configurable redirects, and per-site basic-auth + custom headers. Browser-based checks load the page in real Chromium and capture `console.error` and unhandled exceptions before customers see them.
Checkout Flow Testing — Luma & Hyvä Presets
A real Chromium browser walks Product → Add to Cart → Cart → Shipping → Payment, every 5 or 15 minutes depending on your plan. Selectors ship preconfigured for Luma and Hyvä; custom themes drop in their own CSS selectors via the dashboard. Each step is timed independently — when a deploy breaks payment, the alert names the exact step and the JS error caught during the run.
20 Magento Health Collectors
The optional `byte8/module-pulsar` extension exposes `/pulsar/health` with twenty collectors covering cron heartbeat, indexer drift, queue backlog, OpenSearch cluster state, Redis memory + evictions, PHP-FPM pool saturation, SSL expiry, admin 2FA coverage, config hygiene, stuck `pending_payment` orders, media integrity (webshell detection), Varnish reachability, and more. Each collector has a per-site mute and a Critical-only override.
Alert Routing With Real Noise Controls
Route alerts to Slack, Discord, email, or PagerDuty (Fortress). Each collector has individual override modes — Off, Critical only, or normal — so a flapping cron consumer can't drown the channel. Confirmation thresholds make sites alert only after N consecutive failures; site-level mute handles maintenance windows; auto-resolve fires when the run goes green again.
Supercharge with the Magento extension
Optional — uptime monitoring and page checks work out of the box for any store. The extension unlocks 20 health collectors, checkout flow testing, and deep Magento insights.
The Magento extension surfaces internal state nothing external can see
Each collector has an admin toggle, a per-site override (Off / Critical-only / normal), and a documented threshold. Available on Guard and Fortress tiers; the extension itself is MIT-licensed.

Pulsar vs New Relic, Datadog & Uptime Robot
These tools watch different layers of the stack. APM (New Relic, Datadog) watches server health; uptime monitors (Uptime Robot, Pingdom) watch whether the URL responds; Pulsar watches whether customers can actually buy. Most teams run one of the first two and still miss the Magento-specific failures below.
