Website Monitoring For Online Stores
Every minute your store is down, revenue walks out the door. A broken checkout page at 2 AM does not wait until morning to cost you money. Sentinel monitors your entire purchase flow every 30 seconds so you can catch outages, SSL lapses, and rendering failures the moment they happen, not when a customer emails to complain.
End-to-End Coverage
What to monitor on an online store
A storefront has more failure points than a typical website. Payment gateways, SSL certificates, product APIs, and checkout flows all need to work in concert. Here is what Sentinel watches for you.
Storefront homepage
Verify your main storefront loads correctly every 30 seconds. A slow or broken homepage turns browsers into bounces.
Checkout and payment pages
Monitor every step of the purchase flow from cart through payment confirmation. A single broken page means abandoned orders.
SSL certificates
Track certificate validity and expiry dates. An expired SSL certificate triggers browser security warnings that destroy buyer confidence instantly.
"Add to Cart" keyword presence
Use keyword monitoring to confirm critical elements render on product pages. If the Add to Cart button disappears, you will know within seconds.
Product API endpoints
Monitor headless commerce APIs, inventory feeds, and third-party integrations that power your catalog and pricing.
DNS records for custom domains
Detect unauthorized DNS changes that could redirect your store traffic or break custom domain storefronts.
Protect Every Transaction
Why online stores trust Sentinel
Revenue Protection
Industry data puts the average cost of e-commerce downtime at $5,600 per minute. Sentinel checks your store every 30 seconds from four global regions, cutting detection time from minutes to seconds so you can respond before the losses stack up.
Checkout Validation
Uptime alone does not tell the full story. Sentinel's keyword monitoring verifies that your cart, checkout, and payment forms actually render. A 200 OK status code means nothing if the buy button is missing from the page.
Customer Communication
When incidents happen, branded status pages keep your customers informed without flooding your support inbox. Show real-time incident updates and estimated resolution times on a page that matches your store's identity.
30-Second Detection
Most monitoring tools check every five minutes. That is a five-minute window where your checkout could be broken and you would not know. Sentinel's 30-second intervals catch outages before they have time to impact a meaningful number of sales.
