What is the difference between Sentry and traditional logging?

Traditional logging provides you with a trail of events. Some of those events are errors, but many times they’re simply informational. Sentry is fundamentally different because we focus on exceptions, or in other words, we capture application crashes. We discuss in more detail here and on our blog.

What languages does Sentry support?

Sentry supports every major language, framework, and library. You can browse each of them here .

How much does Sentry cost?

You can get started for free. Pricing depends on the number of monthly events, transactions, and attachments that you send Sentry. For more details, visit our pricing page .

iOS Error Tracking & Performance Monitoring

Actionable insights to resolve iOS performance bottlenecks and errors. Improve your monitoring workflow with a full view of releases so you can mark iOS errors as resolved and prioritize live issues.

Getting Started is Simple

Just run this commmand to sign up for and install Sentry.

Click to Copy

brew install getsentry/tools/sentry-wizard && sentry-wizard -i ios

And then to setup Sentry Tracing add the below code snippet.

Click to Copy

import Sentry

SentrySDK.start { options in
    options.dsn = "https://[email protected]/0"

    // Example uniform sample rate: capture 100% of transactions
    // In Production you will probably want a smaller number such as 0.5 for 50%
    options.tracesSampleRate = 1.0

    // OR if you prefer, determine traces sample rate based on the
    // sampling context
    options.tracesSampler = { context in
         // Don't miss any transactions for VIP users
        if context?["vip"] as? Bool == true {
            return 1.0
        } else {
            return 0.25 // 25% for everything else
        }
    }
}

Session Replay

Get to the root cause of an issue faster by watching replays of real user sessions with best-in-class privacy controls. Understand when, where, and how an error is impacting your app without having to repro it yourself, talk to a customer, or expose sensitive data.

iOS Performance Monitoring

Quickly identify performance issues and view the full end-to-end distributed trace to see the exact poor-performing API call and what caused it. Measure everything from warm starts to froze frames so you can improve iOS performance with max efficiency, not max effort.

iOS Continuous Profiling

Get code-level insight into how your application performs in production environments on real user devices. Find the root cause of slowdowns and issues consuming the most resources, like CPU or memory, and affecting iOS application performance on your user’s mobile device.

Get iOS Crash Reporting With Complete Stack Traces

Reveal hidden context in Apple’s incomplete crash data by automatically symbolicating unreadable symbols. Handle Cocoa iOS crashes with complete context using the React Native SDK while the Objective-C SDK runs in the background.

Fill In The Blanks About iOS Crashes

See what the app was doing when the iOS crash occurred: every user action, controller changes, and custom breadcrumbs. Record events when devices are offline or in airplane mode, then send crash reports as soons as connection is regained.

Resolve iOS Crashes With Better Data

Improve Cocoa error monitoring workflow with a full view of releases so you can mark errors as resolved and prioritize live issues. Learn in which version bug first appeared, merge duplicates, and know if things regress in a future release. Add commit data to automatically suggest an owner of each iOS crash and instantly send deploy emails.

“Being able to use Sentry to monitor the performance as well as our mobile applications is important. Using one solution to monitor the entire application stack gives our engineers the visibility they need to deliver a first-rate experience for our customers.”

FAQs

Sentry doesn’t impact a web site’s performance.

If you look at the configuration options for when you initialize Sentry in your code, you’ll see there’s nothing regarding minimizing its impact on your app’s performance. This is because our team of SDK engineers already developed Sentry with this in mind.

Sentry is a listener/handler for errors that asynchronously sends out the error/event to Sentry.io. This is non-blocking. The error/event only goes out if this is an error.

Global handlers have almost no impact as well, as they are native APIs provided by the browsers.
