It can be hard to figure out why response times are high in Java applications. In my experience, when engineers investigate this type of issue, they typically use one of two methods: They either apply a process of elimination to find a recent commit that might have caused the problem, or they use profiles of the system to look for the cause of value changes in relevant metrics.
When developing modern applications, product managers, designers, and website developers need to understand how users interact with web pages in order to guide those users through their desired journeys. For example, teams need to know if users ever see the content near the bottom of the page, where to place CTAs to ensure they are in high-traffic areas, and how to compare different pages based on user engagement.
Datadog Session Replay in Real User Monitoring (RUM) enables customers to capture and visually replay the web and mobile experience of their end users. With Session Replay, customers can quickly find and address UX errors by seeing precisely what actions an end user took, the point where they got stuck, and the outcome encountered as a result. Session Replay allows for easier troubleshooting and debugging because it delivers visible, insightful context into frontend errors.
OpenTelemetry (OTel) is an open-source, vendor-neutral observability solution that provides a suite of components—including APIs, SDKs, and a data collector—that enable teams to collect and communicate telemetry data from cloud-native applications and services. OTel also defines the OpenTelemetry Protocol (OTLP), a standard for the encoding and transfer of telemetry data.
Today’s modern applications are made up of thousands of loosely connected private and publicly exposed APIs, each serving a specific function. This dynamic API landscape, in combination with the decentralized nature of microservice development, can be overwhelmingly challenging to manage—let alone govern or secure adequately. API sprawl is often created as a result, leading to fragmented or nonexistent internal API documentation, knowledge bases, and toolsets.
As your applications grow, your teams may be faced with managing a complex, expanding mesh of potentially thousands of loosely connected APIs—each one a new point of failure that can be difficult to track and patch. API sprawl comes naturally in rapidly expanding, distributed applications, and the difficulty of maintaining centralized knowledge and toolsets for your APIs creates friction when teams need to leverage APIs they don’t own.
In Part 1 of this series, we talked about some challenges with building sufficient coverage for detecting security threats. We also discussed how telemetry sources like logs are invaluable for detecting potential threats to your environment because they provide crucial details about who is accessing service resources, why they are accessing them, and whether any changes have been made.
