Collecting Service Telemetry Data

In the previous chapter, we explored the topic of service reliability and described various techniques for making your services more resilient to different types of errors. You learned that reliability-related work consists of making constant improvements in incident detection, mitigation, and prevention techniques.

In this chapter, we are going to take a closer look at various types of service performance data, which is essential for setting up service health monitoring and debugging and automating service incident detection. You will learn how to collect service logs, metrics, and traces, and how to visualize and debug communication between your microservices using the distributed tracing technique.

We will cover the following topics:

• Telemetry overview
• Collecting service logs
• Collecting service metrics
• Collecting service traces

Now, let’s proceed to the overview of all the techniques that we are going to describe...
