May 2017 Summaries

Resolving errors efficiently is crucial for maintaining customer satisfaction and reducing support issues, as many companies struggle with ensuring that bug fixes genuinely address customers' problems. Developers often move on to other tasks before verifying fixes in production, leading to unresolved errors and increased customer complaints. Rollbar offers a solution by automatically monitoring production code changes and tracking errors to resolution, thus saving time and improving customer experience. It provides several features, such as automatically tracking regressions, resolving errors in specific code versions, integrating error resolution into commit messages, merging duplicate errors, muting non-critical errors, and auto-resolving old errors. These features ensure that only relevant issues demand attention, and reactivation notifications help maintain confidence in resolutions. Additionally, Rollbar facilitates customer follow-up by providing a complete record of affected users, helping companies turn potential negative experiences into positive ones. By regularly reviewing and resolving errors with tools like Rollbar, companies can enhance visibility and responsiveness to new issues, ultimately building trust and satisfaction among their customers.

The new feature of merging and un-merging errors in Rollbar allows users to combine multiple errors into a single group for streamlined management and improved metric accuracy. Users can merge errors by selecting them from the error Items feed and setting various parameters before finalizing the merge, which helps in organizing duplicated errors efficiently. If an error is incorrectly merged, it can be easily un-merged, providing flexibility in error management. The tool also includes search functionalities to view grouped or member errors separately, enhancing the debugging process. Rollbar encourages users to utilize this feature to save time and improve error handling, offering a 14-day free trial for new users to explore its benefits.

Version 2.0 of the JavaScript notifier SDK introduces significant updates, including support for isomorphic applications that function on both client and server sides, and a standardized configuration and logging interface consistent with other language notifiers. This update unifies separate notifier libraries, allowing for uniform exception logging across environments and offering a single library solution. Developers can now create configuration objects for Rollbar, which can be initialized in both browser and server environments, with examples available for frameworks like Angular and Express. Rollbar is no longer a singleton but supports multiple instances, enabling different loggers with distinct configurations within applications. While upgrading from node_rollbar version 0.6.4 to 2.0.0 is not automatic, it's straightforward, with changes focusing on library initialization and usage, including the deprecation of older methods in favor of a more consistent logging approach. The library remains backward compatible, and developers are encouraged to adopt the new methods and contribute to its open-source improvement.

Instacart, a prominent player in the on-demand grocery delivery market, relies heavily on Rollbar for continuous monitoring and error management to maintain its promise of one-hour deliveries, a critical component given the rapid scaling and complex logistics involved in servicing thousands of orders per minute. As a trailblazer in the online grocery sector, Instacart partners with major chains to offer users in-store prices with a simple delivery charge, while employing thousands of shoppers across the U.S. to fulfill these orders. The engineering team, which has grown significantly, integrates Rollbar into their continuous deployment cycle, allowing for swift detection and resolution of errors, ensuring that both their consumer and shopper apps remain reliable. Rollbar's detailed error forensics and proactive alerting are essential to Instacart's operations, enabling the engineering team to prioritize error resolution based on impact, thereby enhancing their ability to deliver smooth, error-free experiences to customers and shoppers alike.

The recent major upgrade to the Rollbar PHP notifier SDK, now at version 1.0, introduces significant improvements in architecture, style, and reliability, making it easier for customers to integrate their PHP applications with Rollbar. The update includes support for Composer, the prevailing dependency management tool in PHP, and adopts standardized namespaces and logging methods, aligning with modern PHP standards and ensuring backward compatibility with the previous version, 0.18.2. The enhancements also make the SDK more user-friendly and reliable, addressing outstanding issues from earlier releases and facilitating a smoother setup experience. Existing users can easily transition to the new version by updating their composer configurations, while new users are encouraged to explore the enhanced capabilities with a 14-day free trial.
