It helps bring visibility into systems.* – Wikipedia 7 | 8 | Tracing is one of the important pillars for measuring observability along with logs and metrics. It's a way of thinking about the system, a way of being able to ask the system questions, that you need the answer to when you didn't know the questions beforehand. On the other hand, alerting is a way of asking questions when you do know the question beforehand. 9 | 10 | Distributed Tracing can be quite helpful in answering questions for your distributed system like, 11 | 12 | * Root cause analysis 13 | * Performance optimisation 14 | * dependency analysis of services 15 | 16 | ## Selenium-4 17 | It has number of new exciting features and one such is a cleaner code for Selenium Grid along with support for distributed tracing via OpenTelemetry APIs. This is pretty exciting and important feature for the admins and devops engineers to trace the flow of control through the Grid for each and every command. 18 | 19 | Distributed tracing has two parts: 20 | 21 | 1. Code instrumentation: Adding instrumentation code in your application to produce traces. The major instrumentation parts are done neatly by the developers of Selenium project, which leaves us to consume it by using Selenium Grid start-up command along with Jaeger. 22 | 23 | 2. Collection of data and providing meaning over it, Jaeger has a UI which allows us to view traces visually well. 24 | 25 | Steps to start tracing your tests, 26 | 27 | * Start Jaeger via docker(as its easy) 28 | 29 | * Instrument your Selenium Grid start-up command with Jaeger tracing as in [start-grid-distributed.sh](/start-grid-distributed.sh) and [start-grid-standalone.sh](/start-grid-standalone.sh) for standalone mode. 30 | 31 | * Now execute your tests tests, and navigate to `http://localhost:16686/` to view the outputs. 32 | 33 | ## Pre-requisites 34 | Assuming you have java and docker running on your machine, 35 | 1. Install [Jaeger](https://www.jaegertracing.io/download/) via docker 36 | 2. Selenium-server.jar refers to the latest alpha version of selenium releases (Tested with Alpha 5) 37 | - Download from here: https://github.com/SeleniumHQ/selenium/releases/latest 38 | - Put jar in the repo root directory 39 | - Rename to `selenium-server.jar` 40 | 41 | ## Start Jaeger via docker server 42 | The simplest way to start the all-in-one is to use the pre-built image published to DockerHub (a single command line). 43 | 44 | ``` 45 | $ docker run --rm -it --name jaeger \ 46 | -p 16686:16686 \ 47 | -p 14250:14250 \ 48 | jaegertracing/all-in-one:1.17 49 | ``` 50 | You can then navigate to http://localhost:16686 to access the Jaeger UI. 51 | 52 | ## Instrument your Selenium Grid command 53 | The startup scripts use maven to download `opentelemetry-exporter-otlp` and transitive dependencies to `./target/dependency`. 54 | This folder is added to Selenium Server's classpath. When started this way the selenium server will inform you that it has found a tracer on stdout. 55 | 56 | Refer [start-grid-distributed.sh](/start-grid-distributed.sh) if you want to start Grid in distributed mode. 57 | 58 | ```curl http://localhost:4444/status``` to check if your grid deployment is ready 59 | 60 | ![Grid status](/images/grid-ready.png) 61 | 62 | ## Execute your tests 63 | 64 | ```shell 65 | ./mvnw test 66 | ``` 67 | 68 | This will execute the [SeleniumGridTest](src/test/java/com/thoughtworks/tracing/SeleniumGridTest.java) Class. 69 | Navigate to http://localhost:16686/ to view the resulting traces in Jaeger. 70 | 71 | Under services look up for `selenium-router` and notice actions for each call made by your tests.
