Elevating Digital Service Excellence: The Synergy of Real User Monitoring and Application Performance Monitoring

In today's digital landscape, the adoption of Splunk Real User Monitoring (RUM) and Splunk Application Performance Monitoring (APM) is pivotal for organizations aiming to enhance their web presence and user experience. RUM is diligently employed to monitor the genuine interactions of users with web and mobile applications, providing a granular view of user experience in real-time.

Concurrently, APM is harnessed to investigate application performance, offering critical insights into transaction speeds and system health. Both are integral components of an observability suite that caters to the multifaceted nature of modern digital ecosystems, which encompass on-premise, hybrid, and multi-cloud environments. The integration of RUM and APM is showcased as a strategic move within a growth engineering team, underscoring its significant role in improving marketing operations and public-facing websites.

By using observability tools, we can take a preemptive and informed approach to delivering digital services. This shifts incident management from reactive to showcasing digital resilience and excellence.

The Growth Engineering Team at Splunk has embarked on a digital resilience journey, with the mission to maintain public-facing websites and internal portals. Their objective is to provide a world-class customer experience by leveraging the power of Splunk products. To achieve this goal, the adoption of observability tools became imperative to address inefficiencies and the apparent lack of service health visibility.

With the introduction of Real User Monitoring (RUM) and Application Performance Monitoring (APM), the team is now equipped to detect incidents, isolate and prioritize events, and accelerate root cause analysis effectively. This strategic move has enabled the team to transform from a reactive to a forward-thinking approach, enhancing their ability to recover quickly from disruptions and adopt new operating models seamlessly.

The adoption of Splunk's observability tools has proven to be a critical step in the team's journey towards digital resilience. Observability has provided the team with end-to-end visibility, allowing them to monitor the health of their services and correlate events across different teams and microservices. This unified perspective is essential for resolving issues rapidly and efficiently.

As a result of these efforts, the team has reported significant improvements in key performance indicators, including faster page load times, increased engineering efficiency, and improved core web vitals. The team's utilization of RUM has been particularly impactful, allowing them to track automated user sessions across websites and applications. For instance, when trial sign-ups on the website were failing, RUM enabled the engineering team to quickly identify and resolve the issue, minimizing the potential impact on users. Similarly, APM has been instrumental in ensuring the performance of business-critical workflows.

During a product release, APM allowed the team to address an outage alert swiftly, maintaining a 99.9% uptime and boosting engineering productivity by 50%.

Overall, the integration of RUM and APM has set the stage for a more resilient digital presence, empowering the Growth Engineering Team to deliver superior customer experiences and drive business success. This journey towards digital resilience serves as a testament to the power of observability tools in optimizing user experience and operational efficiency.

Application Performance Monitoring (APM) and Real User Monitoring (RUM) are crucial for ensuring service health and optimizing user experiences. Internally, Splunk leverages its own suite of products, including APM and RUM, to monitor and enhance its service offerings. The utilization of these tools within the growth engineering team is shared, demonstrating the tangible advantages of APM and RUM.

APM and RUM collectively provide comprehensive visibility into how services perform and how users interact with applications. By integrating both front-end and back-end monitoring, teams can rapidly identify and resolve issues, often before they significantly impact users. These tools offer capabilities ranging from detailed waterfall charts of user interactions to real-time correlation of traces, which are instrumental in accelerating troubleshooting efforts.

Splunk's internal stories serve as a testament to the effectiveness of APM and RUM. One case study highlights the ability of RUM to detect and address a failure in website sign-up forms, allowing for a swift resolution that was three times faster, thereby preserving the company's brand reputation.

Another example showcases how APM enabled the back-end engineering team to maintain a 99.9% uptime and improve engineering productivity by 50% despite increased traffic.

The integration of APM with RUM is particularly beneficial, as it connects front-end user experiences with back-end service performance, providing a holistic view of the system. This end-to-end visibility is crucial for monitoring complex ecosystems, such as, with its multitude of endpoints. By using APM and RUM in unison, teams can now monitor and optimize Splunk's digital ecosystem more efficiently.

The success of APM and RUM integration at Splunk is quantifiable, with impressive key performance indicators (KPIs) such as a 50% faster page load times, a 25% increase in engineering efficiency, and a 60% improvement in core web vitals.

These statistics underline the transformative impact of Splunk's observability tools in creating resilient digital experiences and fostering a forward-thinking approach to service health management.Screenshot 2024-03-14 at 9.55.30 AM.png
