Four years ago, we stepped on some big toes with our developer-first performance monitoring. Since then thousands of software teams have adopted our modern APM solution. But while Performance checks off a lot of boxes, some dev teams juggle separate tools for metrics, leading to a fractured experience. And honestly, what good is a metric without all the context you get from Sentry? Not very – it makes tying problems back to underlying errors or performance issues unnecessarily difficult.

With the release of.NET 8, Microsoft released a new framework called.NET Aspire that’s shaking up the way distributed applications are crafted. Aspire makes it painless to configure and deploy distributed apps in.NET. You can check out the Aspire docs for a full rundown.

On March 12th 2024, Google is launching a new Core Web Vital metric, Interaction to Next Paint (INP). INP will replace First Input Delay (FID) and will change the way your sites are assessed for performance by Google, which ultimately affects how your sites rank in search engine results. TL;DR: You need to start optimizing for INP today so your sites are not negatively impacted after March 12th.

Based on our experience working with thousands of mobile developer teams, we developed a mobile monitoring maturity curve here at Sentry. We hypothesized that once teams achieved stability and were no longer firefighting and fixing crashes, they’d shift to streamlining workflows and eventually focus more on optimizing mobile app performance. In a recent workshop, we asked mobile devs where they fell on the curve. The results were surprising.

You may have noticed that the banners asking you to accept “cookies” whenever you visit a website have gotten bigger and more annoying over time, especially if you browse the internet in Europe. This is in response to laws and regulations that are meant to protect users from being tracked unless they agree to be tracked. The requirement in Europe is that if you want to use cookies, subject to a few narrow exceptions, the purposes must be disclosed with granularity and agreed to in detail.

When I first had the idea for this post, I wanted to provide a collection of actionable ways to handle errors caused by API rate limits in your applications. But as it turns out, it’s not that straightforward (is it ever?). API rate limiting is a minefield, and at the time of writing, there are no published standards in terms of how to build and consume APIs that implement rate limiting.

Imagine this: Your website is getting a lot of traffic and you have some kind of metrics, logging, or performance monitoring setup (maybe even Sentry). You’re alerted to something… odd. You open up your error and see that a request was interrupted by another request. Uh oh. This sounds like a user was rage-clicking , clicking like crazy making duplicate requests. You weren’t expecting that!

Sentry Cron Monitoring alerts you when your scheduled jobs fail and gives you the context you need to fix it - like we do with error and performance issues. Cron Monitoring focuses on serving code-level insights behind missed and failed jobs and relating them to errors already in your issue stream.

Today, Sentry metrics in beta and free to use – eligible users will now see Metrics in their Sentry accounts. This isn’t just another tool; it’s your new best friend for tracking the data points that matter most to you over time. With Metrics, you can pinpoint and resolve issues with correlated traces, ensuring your product/service/code is always running as intended.

Breadcrumbs provide rich context about what steps your application and user took prior to an error. As this information isn’t captured in the stack trace, Breadcrumbs can be a game-changer for debugging your application.

Open-source error tracking that helps developers monitor and fix crashes in real time. Iterate continuously. Boost efficiency. Improve user experience.

Sentry provides open source error tracking that gives you insight into every crash in your stack as it happens, with the details needed to prioritize, identify, reproduce, and fix each issue. Sentry supports all popular languages and platforms, and offers a perspective that enables you to see which errors are doing the most harm to your business and help you understand how issues affect your bottom line.

Find out about exceptions right away. Set up Sentry in minutes with just a few lines of code. Get notifications via email, SMS, or chat as part of an existing workflow when errors occur or resurface.

Quickly find and fix production errors. Triage, reproduce, and resolve errors with max efficiency and visibility. Exception handling with Sentry helps developers build better apps and iterate faster.

See the impact of each release. Integrate error tracking with your commit and deploy workflows. Aggregate events to see where bugs happen, how often, and who's affected before users even notice.

Error tracking built for community. Sentry started as and remains a 100% open-source project, now delivered as a hosted service. Development aligns to security, observability, and production at scale.

Users and logs provide clues. Sentry provides answers.
