海外TECH	DEV Community	Distributed Tracing with OpenTelemetry - Part II	https://dev.to/signoz/distributed-tracing-with-opentelemetry-part-ii-3ieo	Distributed Tracing with OpenTelemetry Part IIThis article was originally posted on SigNoz Blog and is written by Nitin Rohidas In the previous article we learned what distributed tracing is why it is necessary how to do tracing encountered challenges with existing tracing tools and finally discovered that there is a more mature option available for the industry to adopt in terms of telemetry and observability In this article we will be trying to understand OpenTelemetry in more depth To begin we will examine how OpenTelemetry addresses some of the issues confronting the observability ecosystem OpenTelemetry provides specification standards for the industry to adopt for all three key signals namely Traces Metrics and Logs OTEL defines standards for all three signals It provides a reference implementation of the specifications in multiple languages so that the adoption is easy for the developer community It means developers across popular languages can instrument code using the Otel libraries which will produce signals in standard formats OpenTelemetry Standard and Implementation Libraries supportIt provides a more loosely coupled Observability stack architecture which reduces coupling with vendor agents and allows consumers to change the tools as per their requirements It provides a set of tools and SDKs to customize the instrumentation requirements for many languages check Understanding OpenTelemetry Libraries section below It also provides Auto Instrumentation capability which is a big win wherein developers do not need to code any instrumentation logic and all of it is done by the OpenTelemetry agent in a magical way Auto Instrumentation also called as Zero Code Instrumentation means without any additional code required by developers OTEL can instrument by injecting bytecode if we use the language supported auto instrumentation library There is support for Java so it becomes easy to use without doing any additional code in your application This feature saves a huge amount of time in instrumenting your codebase Provides Rich Telemetry data which is an important requirement for building greater insights into the system under observation Provides a rich set of plugins receivers exporters to help with incremental adoption by building adapters that can work with most of the visualization tools To give more color to these advantages and benefits let s try to see a typical OpenTelemetry architecture How OpenTelemetry fits in the entire application stack OTel agent sends data to OTel collector from where you can export data to a backend of your choiceIn the diagram above you can see following things Instead of using proprietary agents of any FOSS Vendor tools in microservices we are now using OpenTelemetry agents libraries This keeps the client codebase free of any vendor or tool specific native instrumentation libraries The signal data is communicated via OTLP protocol which is the standard OpenTelemetry uses It also supports GRPC HTTP as the medium of communication All the signal data is sent to a Collector component which is considered to be the heart of the system It is optional but any matured and complex implementation will need an OpenTelemetry collector component in the architecture All the data gets processed via the Collector and then sent to different observability backends More on Collectors later but collector is responsible to receive process and send the signal data to the target visualization tool Application telemetry data can now be exported to multiple backends depending on the requirements Also note that you can plugin various out of box exporters for target backend For example Jaeger backend accepts both jaeger format as well as OTLP format But Zipkin needs data in Zipkin format so Zipkin exporter translates the trace data from OTLP to Zipkin native format In the diagram you can also see that we can configure the exporters directly from the agent library without routing the traces via collector but such implementations are for simplified requirements only You can also choose SigNoz as your observability backend SigNoz is an open source observability platform built to support OpenTelemetry natively It provides metrics monitoring ditributed tracing and logs management under a single pane of glass As SigNoz is open source it can be self hosted and the installation comes packed with an OpenTelemetry Collector Once your application is instrumented with OTel libraries you can configure the exporter to send telemetry data directly to SigNoz Understanding OpenTelemetry Libraries Core libraries of OpenTelemetryThe API is the bare bones interface for instrumentation and does not provide any implementation Third party libraries or vendors can instrument their code using the API The SDK is a complete language library that provides implementations of the API so we can instrument our code manually if required It is what we pull directly into our applications It doesn t implement exporters which are separate libraries that have a dependency on the SDK API SDK and Third party Library design Pic Ref Exporters are components that are an extension of the OpenTelemetry package Exporters are libraries that send the instrumented telemetry data to backends Vendors may be required to provide an implementation in order to convert data from OTLP to its native format Ideally most vendors should start working with the OTLP format in the long run for best portability What is Auto Instrumentation And here the magic of OpenTelemetry unfolds Developers will typically need to write instrumentation code to instrument their application code which can be hard and laborious This is where Open Telemetry s Auto Instrumentation shines It is basically a telemetry collection method that do not require the end user to modify the application s source code Methods vary by programming language and examples include code manipulation during compilation or at runtime monkey patching or running eBPF programs For most typical use cases you won t need to write instrumentation code yourself You can use the language specific Auto Instrumentation library and relax But it may happen that if you need to add custom span information or custom data attributes to spans then you can use the manual instrumentation approach i e using the API and SDK to write your own instrumentation logic Demo of Distributed Tracing with OpenTelemetry in a Spring Boot applicationLet s work with an example to see OpenTelemetry in Action The sample Spring Boot Java application will have three microservices and a service registryuser serviceorders servicepayment servicediscovery service eureka server service registry Here s the architecture of the sample Java application along with OpenTelemetry and SigNoz Application architecture along with SigNoz and OpenTelemetry OTel Collector Pre requisitesJava or newerMySql SigNozMaven Installing SigNozSigNoz can be installed on macOS or Linux computers in just three steps by using a simple install script The install script automatically installs Docker Engine on Linux However on macOS you must manually install Docker Engine before running the install script git clone b main https github com SigNoz signoz gitcd signoz deploy install shYou can visit our documentation for instructions on how to install SigNoz using Docker Swarm and Helm Charts Deployment DocsWhen you are done installing SigNoz you can access the UI at http localhost SigNoz dashboard It shows services from a sample app that comes bundled with the application Installing MySqlDownload MySQL community version

localhost and make sure your discover service registry with Eureka server is up and running Eureka server is up and runningSetting up Opentelemetry agentFor instrumenting Java applications OpenTelemetry has a very handy Java JAR agent that can be attached to any Java application The JAR agent can detect a number of popular libraries and frameworks and instrument it right out of the box You don t need to add any code for that Download the latest version of the Java JAR agent and copy jar agent file in your application code We have placed the agent under the folder named agents Placed OpenTelemetry Java Jar agent under a folder named agents Setting up SigNoz as the OpenTelemetry backendTo set up OpenTelemetry to collect and export telemetry data you need to specify OTLP OpenTelemetry Protocol endpoint It consists of the IP of the machine where SigNoz is installed and the port number at which SigNoz listens OTLP endpoint for SigNoz lt IP of the machine gt If you have installed SigNoz on your local machine then your endpoint is Create a start sh script with below environment variables and move it to scripts folder Notice that we have updated the OTLP endpoint under

tables after running microservices Visualizing traces data with SigNoz dashboardsTo visualize the traces data with SigNoz we first need to generate some user data by interacting with the spring boot application Generating user data by interacting with the sample appYou need to generate some user data to see how it appears in the SigNoz dashboard The sample application comes with an UI to interact with the app Use the below command in the root folder to launch the UI npm install g serveserve l uRunning sample app UIUse the buttons to interact with the app and generate some data For example click Create User button to create a new user in the MySQL db Create a new userNow go to SigNoz dashboard you will notice the list of service names that we configured user serviceorder servicepayment serviceMicroservices in our Java app being monitored in the SigNoz dashboardYou can play around with the dashboard to see what data is captured Below is a handy guide on how to use the SigNoz dashboard to see the captured data How to use SigNoz dashboard to analyze tracesThe traces tab of the SigNoz dashboard provides powerful filters to analyze the traces data You can use a number of filters to see traces data across many dimensions For example See the count of requests by service and HTTP Status codeUse advanced filters to see count of requests by service and HTTP status codeRun aggregates on your tracing dataYou can run aggregates like avg max min th percentile th percentile on your tracing data to get analyze performance issues in your application Run aggregates using the dropdown on your traces data quickly Get more granular details by grouping traces dataYou can also see these aggregates in more granular detail by grouping them by service name operation HTTP URL HTTP method etc Group aggregates across a list of dimensions Identify latency issues with Flamegraphs and Gantt chartsYou can inspect each span in the table with Flamegraphs and Gantt charts to see a complete breakdown of the request Establishing a sequential flow of the user request along with info on time taken by each part of the request can help identify latency issues quickly Let s see how it works in the case of our sample Spring Boot app Go to operation filter on the left navigation and apply two filters payment transfer id id amount amount and service name payment service Click on the single event listed in the table as shown below Use filters to inspect spans that you want to investigate furtherYou will be able to see the Flamegraph of the selected span which shows how the request traveled between the payment service and the user service You can also use the Gantt chart to analyze each event in detail Flamegraph and Gantt chart for the selected event showing payment service traces with HTTP semanticsDatabases traces which show semantics related to mysql db and query detailsSigNoz also provides a detailed view of common semantic conventions like HTTP network and other attributes The end to end tracing of user requests can help you to identify latency issues quickly ConclusionDistributed tracing is a powerful and critical toolkit for developers creating applications based on microservices architecture Using OpenTelemetry you can implement distributed tracing easily for your distributed application It also makes your instrumentation future proof as you avoid any vendor lock in OpenTelemetry and SigNoz provide a great open source solution to implement distributed tracing for your applications You can try out SigNoz by visiting its GitHub repo SigNoz GitHub
