Response Time Threshold Monitoring

Alert when your site becomes too slow for users.

Start Monitoring Free← All Monitor Types

Response time threshold monitoring measures how long your site takes to respond and fires alerts when it exceeds your defined thresholds. Slow responses hurt conversions and Core Web Vitals scores.

How it works

Uptrue measures the full round-trip time from request to first byte received. If the response time exceeds your warn threshold, status goes degraded. If it exceeds the critical threshold, an incident opens.

Why this matters

Google uses Core Web Vitals as a ranking signal. A slow server degrades user experience and conversion rates. Monitoring response time separately from uptime lets you catch degradation before it becomes downtime.

Everything you need to know about Uptrue — no fluff.

What thresholds should I set?
A common setup is warn at 1500ms and critical at 3000ms. Adjust based on your users' expectations and current baseline.
No. This measures server response time (TTFB), not full page load including client-side rendering.
