Uptime vs user journey monitoring: what is the difference, and which do you need?
Uptime answers “does the server respond?”. Journey monitoring answers “can a customer get to the end?”. Two questions, two tools, and an order to set them up.
Uptime: one address, one response
An uptime check sends an HTTP request to a URL every minute or every five minutes and checks the status code, the response time, sometimes a word in the page. It catches a hosting outage, an expired certificate or broken DNS. It is simple, fast and cheap.
Journey monitoring: one visitor, several steps
A journey replays what a customer does in a real browser: sign in, search for a product, add it to the cart, fill in a quote form. It runs the JavaScript, loads third-party scripts and checks the result at each step. That is where the outages that cost revenue hide.
- Uptime: fast, cheap, blind to what happens after the first byte.
- Journey: slower and costlier, but it sees the button that stopped working.
- Both together: uptime alerts fast, the journey tells you what is broken.
In which order to set them up
Start with an uptime check on the homepage and on the page that earns money, often the cart or the contact form. Then add a single journey, the most critical one, before adding more. One reliable journey beats ten that alert for nothing.
How Pathly links them
Pathly separates three signals. Ping checks that the address answers. Flow replays the journey in a real Chrome from the EU, with a screenshot of the failing step. Chain tests the API calls behind the site. If you link Ping and Flow, Flow does not open Chrome while Ping is already red: you get one alert, not two.
