Website Performance Monitoring

New Relic website performance monitoring (WPM) is powered by our synthetic monitoring technology. Enter a URL and we launch a set of synthetics minions, or automated bots, to measure things like page availability, Core Web Vitals, page and content load, broken links, and SSL certificate validity.

By default, we launch:

• Three (3) downtime monitors, from different geolocations (which do not count towards your limit). 
• One (1) broken links monitor.
• Three (3) simple browser monitors—one from each geolocation.
• One (1) Core Web Vitals monitor; this only runs when you add your Google PageSpeed Insights API key.

You get 500 checks every month for free. Using the default settings, this is equivalent to three pages checked once a day from three locations.

By providing your credit card number, you unlock 10,000 free checks every month.

Beyond the free limit, each additional check costs a ½ cent. Additional pricing information can be found under the synthetic monitoring section on our list price page.

At this time, we only monitor from any of the 12 public geolocations.

Error codes in the Broken Links section are common browser response error codes:

• 400 Bad Request
• 401 Unauthorized: the page requires a password to access
• 403 Forbidden
• 404 Not Found: the page doesn’t exist
• 500 Internal Server Error (server side)
• 501 Not Implemented (server side)
• 502 Bad Gateway (server side)
• 503 Service Unavailable (server side)
• 504 Gateway Timeout (server side)

See the full list of error codes at List of HTTP status codes.

Use the “Add user” menu item on the bottom-left corner of your screen to add/invite a new user.

This could happen for any of the following reasons:

• In some cases, the data might not be available when a synthetic check is performed.
• The free limit of 500 checks is exhausted and the monitors are paused. 
• There are no monitored checks in the date/time range that you’ve selected.

At this time, New Relic WPM only simulates a desktop view.
