Performance alerts help you catch slowdowns before they become critical:
Available Metrics
- Response Time: Total time to load the page
- TTFB (Time to First Byte): Server processing time
- Content Size: Page size in kilobytes
Configuring Thresholds
- Go to Profile > Alert Settings
- Find performance alert sections
- Enable the alerts you want
- Set appropriate thresholds
- Save settings
Alert Frequency
Performance alerts are limited to one per day per monitor to prevent email overload. If a monitor remains slow, you will receive a single daily reminder rather than repeated hourly alerts.
This applies to all performance alert types (response time, TTFB, content size). Up/down alerts use a separate, shorter cooldown since they are more time-sensitive.
