Site reliability engineers (SREs) are typically good problem solvers. They need to think logically to identify problems, correct them, and prevent them from happening again. In this course, you'll explore several built-in and open-source troubleshooting tools SREs can use for resolving system issues. You'll start by examining the techniques of logging and whitebox and blackbox monitoring used to monitor system events. You'll then work with the various built-in Windows troubleshooting tools, namely the Event Viewer, Resource Monitor, and System Information tools. Next, you'll use Google Cloud Dataflow to process logs, before outlining the purpose and benefits of the StatsD standard and the /api/search endpoint. Lastly, you'll identify how Google's Dapper is used for troubleshooting distributed systems, and the open standards tool, Prometheus, for instrumenting software and exposing metrics.

    4.  Blackbox Monitoring
    3m 7s
    In this video, you'll learn about blackbox monitoring. If whitebox monitoring is supposed to focus on information from specific applications, blackbox monitoring is supposed to focus on information on the system itself. Blackbox monitoring makes sure that the system is functioning properly by monitoring key indicators about the environment your applications are running on. For example, blackbox monitoring can check that you're not running out of disk space. FREE ACCESS

    5.  Using Windows Event Viewer
    3m 2s
    In this video, you'll learn how to access and navigate the Windows Event Viewer. You'll discover where to find the Event Viewer and what data you can find in each section. The Windows Event Viewer has been around for a long time, logging system information for Windows itself as well as apps. FREE ACCESS

    8.  Dapper Characteristics and Use Cases
    5m 6s
    In this video, you'll learn more about Dapper. This software tends toward complex and distributed microservice architectures, which make building applications easier, but each of these microservices are effectively independent modules. Each module can be developed by different teams using different languages and with different requirements. Some modules perform simple tasks without a lot of compute needs, while others might require global distribution across thousands of machines. FREE ACCESS

    9.  Processing Logs with Google Cloud Dataflow
    6m 13s
    In this demo, you'll learn how to process logs using Google's Dataflow work flow tool. To do that, you'll run a simple Python script through Google Cloud Shell and explore the information that was sent. You'll begin by navigating to your Dataflow instance. Then, you'll open up the Cloud Shell. The screen displays the Google Cloud Platform Dataflow service. Now at the top of the screen, make sure you've selected the appropriate project. FREE ACCESS

    10.  The StatsD Standard
    1m 59s
    In this video, you'll learn about instrumenting code. It helps gather information about what's happening in your code, as well as gather metrics about application health. One popular tool for instrumentation is StatsD. It's an open standard that was originally written by Etsy as a metric aggregation daemon. FREE ACCESS

    11.  Prometheus Characteristics and Components
    3m 12s
    In this video, you'll learn more about instrumenting code. You'll learn that instrumenting code is what helps gather information about what's happening in your code, as well as gather metrics about application health. On screen, you'll see a chart with a diagram of a computer system. This diagram shows how Prometheus works by listing the components and their functions. The chart lists these components: Server, Client libraries, Push gateway, Exporters, Alert manager, and Other tools. FREE ACCESS
