Application PerformanceComing soon

Users rarely complain that a site is down — they leave because it is slow. Application performance monitoring will show which requests and services make your app slow, and alert you when it gets worse.

⏳We are building this monitor now. It is already in the app's Add Monitor dialog and becomes available there as soon as it is ready. Create a free account to hear first.

Slow is the new down

Performance problems build up slowly: a query that was fine with a thousand rows takes seconds with a million, an external call adds half a second to every page, a release doubles the response time of one endpoint. Uptime checks see a green light the whole time.

Application Performance Monitoring will measure your application from the inside — requests, errors, database and external calls — and point to the part that is slowing everything down.

What it will check

The plan for the first release. Every check will be stored in a full log, like all Upzilla monitors.

Response times

By endpoint, with the slowest requests first.

Errors

Error rates and the requests that fail.

Database and external calls

How much time each part of a request takes.

Trends

Changes after releases and as traffic grows.

Until then: Website Performance

Website Performance can already measure how fast your pages load, from several locations.

Questions about Application Performance

When will Application Performance Monitoring be available?

We are building it as part of the next Upzilla; many new features arrive before the new year. Create a free account to hear first.

What can I use today?

Website Performance and Page Speed Monitoring measure how fast your pages load from outside, and API Monitoring the response time of your endpoints.

Will it need code changes?

It will need a small agent or integration in your application, depending on the platform.

How is it different from page speed monitoring?

Page speed is measured from outside, as a visitor sees it. Application performance looks inside the application to show why it is slow.
