Technical requirements
This chapter contains Ballerina examples along with different types of observability tools such as Prometheus, Grafana, Logstash, Jaeger, and Elasticsearch. All of this aforementioned software is open source and can be downloaded onto your local computer or the target platform. Make sure that you select the correct operating system (OS) and install any prerequisites if needed.
You can find the code files for this chapter at https://github.com/PacktPublishing/Cloud-Native-Applications-with-Ballerina/tree/master/Chapter08.

Applications that we have mentioned here can also be used as a Docker container. In containerized platforms such as Kubernetes, you can use Docker containers instead of using executables. Each section in this chapter, contains Docker pull commands for all of the Docker images that we have used.
