海外TECH	DEV Community	Implementing OpenTelemetry in Angular application	https://dev.to/signoz/implementing-opentelemetry-in-angular-application-f45	Implementing OpenTelemetry in Angular applicationOpenTelemetry can be used to trace Angular applications for performance issues and bugs OpenTelemetry is an open source project under the Cloud Native Computing Foundation CNCF that aims to standardize the generation and collection of telemetry data Telemetry data includes logs metrics and traces Angular is a frontend Javascript framework that uses HTML and Typescript It s a popular framework used by many organizations for their frontend applications For a user frontend is the user s first interaction point and it is necessary to ensure that your Angular apps provide a perfect user experience Repository of Angular library to deploy OpenTelemetry in Angular applicationUsing OpenTelemetry Angular libraries you can instrument your Angular apps to generate traces from your Angular app to your downstream services Before we demonstrate how to implement the OpenTelemetry libraries let s have a brief overview of OpenTelmetry What is OpenTelemetry OpenTelemetry is an open source vendor agnostic set of tools APIs and SDKs used to instrument applications to create and manage telemetry data logs metrics and traces It aims to make telemetry data logs metrics and traces a built in feature of cloud native software applications The telemetry data is then sent to an observability tool for storage and visualization OpenTelemetry libraries instrument application code to generate telemetry data that is then sent to an observability tool for storage amp visualizationOpenTelemetry is the bedrock for setting up an observability framework It also provides you the freedom to choose a backend analysis tool of your choice OpenTelemetry and SigNozIn this article we will use SigNoz as our backend analysis tool SigNoz is a full stack open source APM tool that can be used for storing and visualizing the telemetry data collected with OpenTelemetry It is built natively on OpenTelemetry and supports OTLP data formats SigNoz provides query and visualization capabilities for the end user and comes with out of box charts for application metrics and traces Now let s get down to how to implement OpenTelemetry Angular libraries and then visualize the collected data in SigNoz Running Angular application with OpenTelemetryStep Install SigNozFrist you need to install SigNoz so that OpenTelemetry can send the data to it SigNoz 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 When 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 applicationStep Get sample Angular appWe have set up two sample GitHub repos in order to demonstrate the example at handSample Angular AppIt contains the sample boilerplate code that we will instrument If you want to follow the tutorial then you should follow the without instrumentation branch Sample Nodejs AppIt contains a basic backend API which we will be calling The backend API is also instrumented with OpenTelemetry to have end to end tracing Step Enable CORS in the OTel ReceiverEnable CORS in the OTel Receiver Under SigNoz folder open the otel collector config yaml file The file is located at deploy docker clickhouse setup otel collector config yamlYou can view the file at SigNoz GitHub repo Inside the file add the following CORS config http cors allowed origins https netflix com URL of your Frontend applicationYou need to update the URL of your frontend application For this tutorial we will be running our frontend application on http localhost lt img alt gt Enabling CORSOnce you make the changes you need to restart the Docker containers Step Instrument Angular app with OpenTelemetryTo instrument the angular app with OpenTelemetry we need to install the OpenTelemetry dependencies npm i jufab opentelemetry angular interceptor amp amp npm i opentelemetry api opentelemetry sdk trace web opentelemetry sdk trace base opentelemetry core opentelemetry semantic conventions opentelemetry resources opentelemetry exporter trace otlp http opentelemetry exporter zipkin opentelemetry propagator b opentelemetry propagator jaeger opentelemetry context zone peer dep opentelemetry instrumentation opentelemetry instrumentation document load opentelemetry instrumentation fetch opentelemetry instrumentation xml http request opentelemetry propagator aws xray save devStep Update app module ts fileimport OpenTelemetryInterceptorModule OtelColExporterModule CompositePropagatorModule from jufab opentelemetry angular interceptor NgModule imports OpenTelemetryInterceptorModule forRoot commonConfig console true Display trace on console only in DEV env production false Send Trace with BatchSpanProcessor true or SimpleSpanProcessor false serviceName Angular Sample App Service name send in trace probabilitySampler otelcolConfig url http v traces URL of opentelemetry collector Insert OtelCol exporter module OtelColExporterModule Insert propagator module CompositePropagatorModule Make sure to update then URL of OpenTelemetry Collector under otelcolConfig In our case since we re running SigNoz in local the URL is v traces You can change the name of the service and other configurations under commonConfig Step Start the angular app and the backend APIFor Angular app Go to the root folder of your Angular application and run the following command yarn startFor backend API Install the dependenciesyarn installIf SigNoz is installed locally run your backend API using yarn run start localIf SigNoz is not installed locally then you would need to set the IP of the machine where SigNoz is installed You can do so by using the below command OTEL EXPORTER OTLP ENDPOINT lt IP of SigNoz gt OTEL RESOURCE ATTRIBUTES service name NAME OF SERVICE yarn run start custom Congratulations You have successfully run your Angular application with OpenTelemetry It s time to see the collected data Step Generate some dataIn order to monitor your Angular application with SigNoz you first need to generate some data Visit http localhost to access your frontend application Using the UI make some calls to the backend API You can check the network tab in your browser to see the requests that you have made Angular Frontend Web UIStep Monitor your application with SigNozWith SigNoz you can monitor the data collected by OpenTelemetry from your sample Angular application You can see end to end traces for your Angular application starting from your frontend application to the downstream nodejs sample app See end to end traces from your Angular application to downstream servicesYou can also monitor errors that takes place in your Angular application SigNoz UI also shows attributes like http status code Monitor errors in your frontend Angular application ConclusionUsing OpenTelemetry Angular libraries you can instrument your frontend applications for end to end tracing You can then use an open source APM tool like SigNoz to ensure the smooth performance of your Angular apps OpenTelemetry is the future for setting up observability for cloud native apps It is backed by a huge community and covers a wide variety of technology and frameworks Using OpenTelemetry engineering teams can instrument polyglot and distributed applications with peace of mind SigNoz is an open source observability tool that comes with a SaaS like experience You can try out SigNoz by visiting its GitHub repo If you are someone who understands more from video then you can watch the our video tutorial on how to implement OpenTelemetry Angular libraries and monitor the application with SigNoz If you face any issues while trying out SigNoz you can reach out with your questions in support channel Further ReadingMonitor gRPC calls with OpenTelemetryDistributed
