App Metrics and Clear Performance Insights

Scout's App Metrics provides real-time visibility into your application's health through an intuitive interface that surfaces what matters most – from response times to error rates, all in one view. It’s your application's performance dashboard, simplified with a UI design made for quick analysis and saving developers and teams valuable time.

Overview

A Comprehensive Overview Page

Get instant visibility of your app's vitals with our auto-refreshing dashboard. Track mean and 95th percentile response times, throughput, error rates – with clear, actionable visualizations. Compare current and historical data to spot trends and catch regressions.

A Comprehensive Overview Page
Auto-refreshing dashboard

Live performance metrics, updated every minute for instant deploy feedback.

Dynamic annotations

Live performance metrics, updated every minute for instant deploy feedback.

30-day lookback window

Track a month of performance trends to quickly spot issues vs historical data.

Endpoints

Endpoint Details – Above and Beyond

Explore your endpoints with comprehensive analytics showing time consumption rankings, throughput, memory allocations, and error rate hotspots. Zero in on specific timeframes to identify the endpoints contributing to performance issues, then confidently resolve them.

Individual Endpoints

You can view metrics for specific controller-action and background job workers. There is a similar chart interaction to the App Performance Overview page, with one difference: your selection will render an updated list of transaction traces that correspond to the selected time period.

Endpoint metrics

Drill into metrics for specific controller actions or background job workers.

Transaction filters

Filter transaction traces by response time, object allocations, date, and more.

Dynamic charts

Leverage dynamic charts to update trace data for the selected time period.

Individual Endpoints
Backround Jobs

Keep Background Job Insights in the Foreground

Monitor your background workers with the same precision as your web endpoints. Track execution time, throughput, latency, memory allocations, and error rates to ensure your async processes run smoothly. Identify bottlenecks and optimize performance where it matters most.

External Services

External Services Dashboard

Keep tabs on your application's external dependencies through our External Services Dashboard: get clear visibility into all your API calls, identify slow services, and see exactly where time is spent in your integrations.

Get Started in Minutes

Add Scout to Your App

With monitoring that "just works" for Rails, Django and more, get running in minutes with Scout's streamlined setup. No extra code needed - just deploy our agent and start getting insights in 5 minutes.

Get started in under 3 minutes with our easy to install Ruby agent.

1

Install our gem. In your gemfile:

gem 'scout_apm'
2

Shell:

bundle install
3

Download your customized config file, placing it at config/scout_apm.yml.

4

Deploy.

Heroku customers

We initially provision your application using environment variables instead of the config/scout_apm.yml. Configuration values set via env variables will take priority over those set via yaml.

For Django, use the following steps (Flask and friends, see full docs):

1

Install the scout-apm package:

pip install scout-apm
2

Configure Scout in your settings.py file:

# settings.py
INSTALLED_APPS = [
    "scout_apm.django",  # should be listed first
    # ... other apps ...
]

# Scout settings
SCOUT_MONITOR = True
SCOUT_KEY = "[AVAILABLE IN THE SCOUT UI]"
SCOUT_NAME = "A FRIENDLY NAME FOR YOUR APP"
3

If you wish to configure Scout via environment variables, use SCOUT_MONITOR, SCOUT_NAME, and SCOUT_KEY instead of providing these settings in settings.py.

4

Deploy.

It takes approximately five minutes for your data to first appear within the Scout UI.

Heroku customers

If you've installed Scout via the Heroku Addon, the provisioning process automatically sets SCOUT_MONITOR and SCOUT_KEY via config vars. Only SCOUT_NAME is additionally required.

Scout supports Laravel 5.5+.

Not using Laravel? Check our documentation.

1

Install the scoutapp/scout-apm-laravel package:

composer require scoutapp/scout-apm-laravel
2

Install the scoutapm php extension (optional, recommended):

sudo pecl install scoutapm
3

Configure Scout in your .env file:

# Scout settings
SCOUT_MONITOR=true
SCOUT_KEY="[AVAILABLE IN THE SCOUT UI]"
SCOUT_NAME="A FRIENDLY NAME FOR YOUR APP"
4

Add the config/scout_apm.php:

php artisan vendor:publish --provider="Scoutapm\Laravel\Providers\ScoutApmServiceProvider"
5

Clear and re-cache your config:

php artisan config:cache
6

Deploy.

It takes approximatively five minutes for your data to first appear within the Scout UI.

Heroku customers

If you’ve installed Scout via the Heroku Addon, the provisioning process automatically sets SCOUT_MONITOR and SCOUT_KEY via config vars. Only SCOUT_NAME is required.

1

For a Phoenix app, add our package to mix.exs (and run mix deps.get):

{:scout_apm, "~> 1.0"}]
2

Download your customized config after signing up and place at config/scout_apm.exs

3

Add to your app:

# lib/your_app_web.ex
defmodule YourApp.Web do
  def controller do
    quote do
      use Phoenix.Controller
      use ScoutApm.Instrumentation
      ...
