Response Time Monitor
A pure response-time uptime monitor - track latency over time and only alert when it genuinely matters.
A response time monitor calls your URL on a schedule purely to measure how long it takes to respond - no up/down status is derived from a status code by default. It's the monitor to reach for when you already know a page returns 200, but what you actually care about is whether it's getting slower over time. Turn on an optional alert threshold and it becomes a slow-response uptime monitor as well, paging your team when latency crosses a line you set, separate from the timeout that defines an outright failure.
How this uptime monitor works
- Add the URL to time and pick an HTTP method.
- Choose a check interval, from every 10 seconds on Max down to every 5 minutes on Free and Entry.
- Set a timeout - how long to wait before the check counts as an outright failure.
- Optionally turn on an alert threshold in milliseconds - separate from the timeout - so the monitor pages your team on a slow response, not just a dead one.
- Every check logs response time to a graph over time, whether or not the alert threshold is enabled.
Response Time Monitor features
Every feature this monitor supports, and which plan it's included on.
Pure response-time tracking
FreeGraphs latency over time without treating every check as a pass/fail up/down status.
Any HTTP method
FreeGET, POST, PUT, PATCH, DELETE, or HEAD, same method picker as the HTTP monitor.
Configurable timeout
FreeHow long to wait for a response before it counts as an outright failure, from 1 to 60 seconds.
Optional slow-response alert threshold
FreeA separate millisecond threshold from the timeout - alert only when a response is slower than you've decided is acceptable, not merely when it fails outright.
Tags and groups
FreeOrganize response time monitors alongside your other monitors.
Email and SMS alerts
FreePer team member, open and recovery alerts on every channel.
Webhooks and Slack alerts
FreeRoute slow-response alerts into Slack or any webhook endpoint.
10-second check interval
Max+The fastest available interval for this monitor type.
30-second check interval
Mid+Faster than the default 5-minute floor.
What's free and what's paywalled
- The response-time graph, timeout configuration, and the optional slow-response alert threshold are all available on every plan, including Free.
- Check frequency follows the standard ladder: 5 minutes on Free/Entry, 30 seconds on Mid, 10 seconds on Max.
- Response time monitors count against the same account-wide monitor limit as every other type (5 to 300, by plan).
Frequently asked questions
How is this different from the HTTP monitor?
The HTTP monitor evaluates status codes and keywords to decide up/down. The response time monitor is purely about latency - it doesn't judge a response as up or down by default, it just times it and, optionally, alerts if a response is unusually slow.
Are there two different alerts on this monitor?
Yes. The timeout defines an outright failure (no response within that window), and the separate, optional alert threshold flags a response that came back slower than you'd like, even though it technically succeeded.
Is response time monitoring free?
Yes, on every plan including Free - 5 monitors, full access to timeout and alert-threshold configuration, at a 5-minute check interval. Mid and Max unlock faster intervals.
