Ruby and Elixir performance monitoring

Build and launch fast apps, faster.

AppSignal helps you inspect and improve the performance of your applications. Enhance your customer's experience, and make sure your apps stay performant.

Real-time alerts.

Get alerts when requests are slow.

Get alerted when requests and background jobs are taking longer than expected. Configure at what threshold you want to be alerted on app, namespace, action and job level.

Request details

Find and fix slow actions.

When you are alerted about a slow request, we link to our detailed sample page. Samples provide the information you need in order to find the cause of the issue. Navigating to other slow requests on the same action is done with a single click.

Breakdown

Breakdown of your action's performance by type.

Request details

See the hostname, path, request ID and other information that was saved for this request.

Overview

Global response times.

Inspect global throughput and performance graphs for your web requests and background jobs. It shows how your apps are improving over time, and is a great indicator of possible app-wide issues.

Sort by impact

List controllers & jobs.

We conveniently list all your controllers and background jobs, so you can sort, inspect and compare their performance. It is a great way to pro-actively improve the slower parts of your app.

Event groups

Which events are slow?

So your entire app is slowing down? Wonder what's causing it? Find out with our slow events graph, and instantly see if particular types of events are causing overall slowness.

Allocations

Do I have memory leaks?

We track the number of memory allocations per event, so you can easily spot which events are using too much of your memory.

Request context

Inspect host metrics for slow requests.

Sometimes issues are caused by your hosts running amok. That's why we keep track of host metrics for each performance sample. Discover when to optimize your infrastructure before blaming lines of code or third-party vendors.
