Distributed Traces and Spans

In distributed tracing, when a request is made to an application, a trace is created that collects performance data from each service involved in processing the request. The trace is made up of spans. Each span represents an operation or logical unit of work performed by a service in response to the request. Services that perform more than one operation to handle the request produce a span for each operation.

What is Monitoring

Monitoring is the process of gathering data to understand whats's going inside of your infrastructure

What is Observability

Observability is taking the same data that you have collected and moving beyond "What is happening" to "Why is it happening"?

Monitoring is the tip of the iceberg. It means the if I want to see the whole picture, I need both.

The course: I'll do gain Datadog skills while monitoring a real e-commerce application that we’ve already built and deployed for you in a virtual machine.

Overview of course topics

Universal Service Monitoring (USM) provides a comprehensive overview of service health metrics across your technology stack without requiring you to instrument your code.

Logs capture event streams from various components of your infrastructure. Datadog Log Management enables you to cost-effectively collect, process, archive, explore, and monitor all your logs.

Metrics can track a wide range of measurements—such as latencies, error rates, or even user signups—within your environment over time. Monitors actively check on these metrics and alert you when critical changes occur, for example, when a threshold indicating a problem is crossed. You can use either metrics or monitors as the basis for service level objectives (SLOs), which define targets for performance and provide a framework for establishing clear standards for service quality.

Integrations are plugins or add-ons that enable Datadog to monitor individual third-party software, services, or tools. With the help of integrations, Datadog can unify different metrics and logs generated by many technologies deployed across your infrastructure.

Dashboards allow you to view curated visualizations of key observability data on a single page. You can create custom dashboards from scratch, but there are also many out-of-the-box (OOTB) or pre-built dashboards available.
