海外TECH	DEV Community	Choosing an OpenTelemetry backend - Things to keep in mind	https://dev.to/signoz/choosing-an-opentelemetry-backend-things-to-keep-in-mind-23ao	Choosing an OpenTelemetry backend Things to keep in mindOpenTelemetry is a Cloud Native Computing Foundation CNCF incubating project aimed at standardizing the way we instrument applications for generating telemetry data logs metrics and traces However OpenTelemetry does not provide storage and visualization for the collected telemetry data And that s where an OpenTelemetry backend is needed Cloud computing and containerization made deploying and scaling applications easier Modern applications make use of modular code and architectures like microservices and serverless Engineering teams can ship features faster and any surge in user demand can be met by just spinning up more containers But every coin has two sides While having benefits like smaller engineering teams and on demand scaling of applications cloud computing and containerization have also increased operational complexity manifolds Troubleshooting an application based on a distributed system for performance issues is like finding a needle in a haystack Collecting data from applications that can act as signals for troubleshooting performance issues is a practice as old as writing software The data that helps to analyze performance issues is known as telemetry data For cloud native applications it became a challenge to have a consistent framework for generating telemetry data OpenTelemetry solves this problem by creating an open standard for generating telemetry data Let s learn a bit about OpenTelemetry What is OpenTelemetry OpenTelemetry is an open source collection of tools APIs and SDKs that aims to standardize the way we generate and collect telemetry data It follows a specification driven development The OpenTelemetry specification has design and implementation guidelines for how the instrumentation libraries should be implemented In addition it provides client libraries in all the major programming languages which follow the specification OpenTelemetry was formed after the merger of two open source projects OpenCensus and OpenTracing in Since then it has been the go to open source standard for instrumenting cloud native applications The specification is designed into distinct types of telemetry known as signals Presently OpenTelemetry has specifications for these three signals Logs Metrics andTracesTogether these three signals form the three pillars of observability OpenTelemetry is the bedrock for setting up an observability framework The application code is instrumented using OpenTelemetry client libraries which enables the generation of telemetry data Once the telemetry data is generated and collected OpenTelemetry needs a backend analysis tool to which it can send the data Why does OpenTelemetry need a backend The founders of OpenTelemetry wanted to standardize two things The way we instrument application codeThe data format of generated telemetry dataOnce we have the telemetry data in a consistent format it can be sent to any observability backend This provides users the freedom to select any OpenTelemetry backend based on their observability needs The aim of OpenTelemetry was always to have a pluggable architecture using which users can build robust observability stacks using additional technology protocols and formats Here s a snapshot showing how OpenTelemetry fits within a microservice based application and an observability backend How OpenTelemetry fits within a microservice based application and an observability backend SigNozThe OpenTelemetry collector acts as the routing layer Once the telemetry data is collected with the help of OpenTelemetry libraries it is sent to the OpenTelemetry collector The OpenTelemetry collector can export the telemetry data in multiple formats to multiple observability backends Things to look out for when choosing an OpenTelemetry backendOpenTelemetry provides you the freedom to choose a backend analysis tool of your choice Most observability vendors currently have introduced support for OpenTelemetry So how do you ensure which OpenTelemetry backend to go for There are three main components that an OpenTelemetry backend is responsible for Data StorageObservability data can be huge The data storage of an OpenTelemetry backend should be highly scalable and query execution performance should be top notch Query ServiceOpenTelemetry has three distinct signals Each signal has different data formats with different use cases for users Moreover the signals are correlated The query service of an OpenTelemetry backend should be built with these considerations in mind VisualizationMaking sense out of data is what impacts the end user of observability dashboards OpenTelemetry backends should provide intuitive dashboards that enable end users to take quick actions on performance issues Below is the list of factors that should be taken into consideration before selecting an OpenTelemetry backend Support for all distinct signals of OpenTelemetryCurrently OpenTelemetry collects telemetry data in three distinct signals namely logs metrics and traces Setting up a robust observability framework requires the use of all three signals An OpenTelemetry backend should be able to ingest and visualize all three signals Moreover the frontend of the OpenTelemetry backend should also provide features to easily correlate the signals Native support for OpenTelemetry semantic conventionsIn OpenTelemetry every component of a distributed system is defined as an attribute The attribute is nothing but a key value pair These attributes are defined by the OpenTelemetry specification as OpenTelemetry semantic conventions For example here is a glimpse of how HTTP conventions look like AttributeDescriptionExamplehttp methodHTTP request methodGET POST HEADhttp targetThe full request target as passed in an HTTP request line or equivalent blog june http schemeThe URI scheme that identifies the used protocolhttp httpsAn OpenTelemetry backend should have native support to store data with OpenTelemetry semantic conventions Existing observability vendors usually transform the data collected using OpenTelemetry semantic conventions into their propriety formats But OpenTelemetry has a huge list of semantic conventions which might not be fully utilized in such scenarios Should allow aggregates on trace dataRunning aggregates on trace data enables you to create service centric views OpenTelemetry also provides you the ability to create custom tags Combined with custom tags and aggregated trace data gives you a powerful magnifying glass to surface performance issues in your services For example you can get the error rate and th percentile latency of customer type gold or deployment version v or external call paypalOpen SourceOpenTelemetry is an open source standard with a huge community backing It is testimonial to the fact that community driven projects can solve large complex engineering problems It is not necessary for the OpenTelemetry backend to be open source But having an open source OpenTelemetry backend can enable you to have a full stack open source solution Open source solutions have more flexibility and if you self host you don t need to worry about things like data privacy Nearly all observability vendors now claim to be compatible with OpenTelemetry But it s difficult to move away from legacy systems A solution built natively for OpenTelemetry can be a good choice for an OpenTelemetry backend And that s where SigNoz comes into the picture Trying out an OpenTelemetry BackendIf you want to play around with an OpenTelemetry backend it is easy to get started with SigNoz SigNoz is an open source APM built natively on OpenTelemetry SigNoz can be installed on macOS or Linux computers in just three steps by using a simple installation script The install script automatically installs Docker Engine on Linux However you must manually install Docker Engine on macOS 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 Once your application is instrumented with OpenTelemetry client libraries the data can be sent to the SigNoz backend by specifying a specific port on the machine where SigNoz is installed You can then use Signoz to monitor application metrics with out of box charts and visualization An OpenTelemetry backend built natively for OpenTelemetry SigNoz provides out of box charts for application metricsThe tracing signal from OpenTelemetry instrumentation helps you correlate events across services With SigNoz you can visualize your tracing data using Flamegraphs and Gantt charts It shows you a complete breakdown of the request along with every bit of data collected with OpenTelemetry semantic conventions Tracing data collected by OpenTelemetry can be visualized with the help of Flamegraphs and Gantt charts on the SigNoz dashboardSigNoz also lets you run aggregates on your tracing data Running aggregates on tracing data enables you to create service centric views providing insights to debug applications at the service level It also makes sense for engineering teams as they own specific microservices Running aggregates on your tracing data enables you to create service centric viewsYou can check out the SigNoz

海外TECH	DEV Community	Medusa + Nuxt.js + Stripe - How to Create a Nuxt.js Ecommerce Storefront from Scratch Using Medusa Part 3	https://dev.to/medusajs/medusa-nuxtjs-stripe-how-to-create-a-nuxtjs-ecommerce-storefront-from-scratch-using-medusa-part-3-3jg0	Medusa Nuxt js Stripe How to Create a Nuxt js Ecommerce Storefront from Scratch Using Medusa Part IntroductionMedusa is an open source headless commerce that allows you to build online stores through its APIs with just a few commands One of its key features is the ease to integrate different payment providers to accept payments when customers place their orders In the second part of this series you added the cart functionality to your Nuxt js storefront Following from there in this guide you will learn how to integrate and use Stripe as a payment provider to allow customers to make payments and place orders You can find the code of this tutorial at this GitHub repository PrerequisitesTo follow along with this tutorial you need the following A Medusa server with some dummy data to work with If you don t have one you can follow the QuickStart guide to install one An admin dashboard to manage your ecommerce store Medusa provides an intuitively designed admin dashboard that you can use The Nuxt js storefront from the second part of the series You can clone the part cart flow branch of this GitHub repository and continue on from there A Stripe account to retrieve the API Keys and secrets to connect your Medusa server with Stripe The account should be in sandbox mode to test out the integration Medusa Server SetupThis section guides you over the steps necessary to add Stripe as a payment provider to your Medusa server Install Stripe PluginGo to your Medusa server directory with cd medusa server and in the root of the project install the Stripe plugin with the following command yarn add medusa payment stripe Stripe Plugin ConfigurationOnce the plugin is installed you need to add configurations for it Open your medusa config js file and look for the plugins section Then add the following object to the plugins array const plugins resolve medusa payment stripe options api key process env STRIPE API KEY webhook secret process env STRIPE WEBHOOK SECRET Where STRIPE API KEY is the Secret key from Stripe you can retrieve it from Stripe s dashboard by click on the Developers link at the top right then choosing API Keys from the left sidebar and copying the Secret key Next you need to add the secret key to your environment variables In your Medusa server open your  env file and add the Stripe key STRIPE API KEY sk test KALKSDLKKMKCDJNJ ️Later on you will come back to stripe s dashboard to copy the Publishable key and add it to the Nuxt js storefront Admin Dashboard SetupTo use Stripe as a payment provider in your storefront you must add it as a payment provider in a region first This section guides you in how to do that using Medusa s Admin Dashboard Add Stripe to a RegionMake sure your Medusa server is running Then start your admin panel with yarn run develop It should run on localhost by default Open the Admin dashboard in your browser log in and click on Settings in the sidebar Then choose Regions Next for every region you want to add Stripe as a payment provider in scroll down the form on the right to Payment Providers and choose Stripe Then click Save ️This set up is very important If the region doesn t have Stripe as a payment provider it will not be available on the storefront Storefront Set UpIn this section you ll learn more about Medusa s checkout flow and how to integrate Stripe as a payment provider Workflow OverviewIn a nutshell the workflow the Nuxt js storefront has to follow to implement a full checkout workflow When the user visits the website an empty cart is created on the Medusa server with a default region and country code During checkout the user fills up a form with their email and shipping address The user chooses a fulfillment provider for the shipping method The user chooses a payment provider and fills any necessary information such as credit card details If the payment is processed successfully the order is placed At each of these steps the cart is updated on the server with new information based on what the user chooses Install Nuxt js Stripe ModuleBefore you start the stripe implementation you need to install a Nuxt js module to help you with that You ll be using Nuxt stripe module to handle the payment confirmation with stripe In the directory of your Nuxt js storefront run the following command yarn add nuxt stripe moduleAfter the installation is complete open nuxt config js and add nuxt stripe module to the modules section with the publishable key passed as an option modules nuxt stripe module publishableKey process env PUBLISHABLE KEY Next go back to the Stripe developer dashboard and copy the publishable key from the API keys page Then create a  env file in the root directory of the project if it doesn t already exist and add the publishable key PUBLISHABLE KEY lt YOUR PUBLISHABLE KEY gt Where lt YOUR PUBLISHABLE KEY gt is the key you copied Add Checkout PageOnce the Stripe module is added to the Nuxt js storefront the next step is to add the checkout page and its components to actually be able to use it Create the file pages checkout index vue with the following content lt template gt lt div class bg ui gt lt div class container mx auto p relative gt lt div class layout base gt lt div class flex flex col

Medusa server is running Then run your Nuxt js storefront yarn run devOnce the storefront is running go to the products page on http localhost products and add a few products to your cart Then at the top right click on the bag icon to see the cart popover Click on the “Checkout button You ll be taken to the checkout page which shows the Summary and Flow components you created earlier Set Up Checkout FlowIn this part you will go through the steps needed to implement the checkout flow in your Nuxt js storefront including the step related to adding a custom payment provider To complete the checkout the customer has to follow and complete four main steps Give their email address Fill up a form with their shipping address Choose a shipping option Choose a payment method to complete their purchase Each of these steps will become a component of their own and they will be rendered in the checkout flow component Wrapper ComponentsCreate the file components Checkout Step vue with the

package yarn add braid vue formulateThen update the build modules property in your nuxt confg js file to include the package export default buildModules braid vue formulate nuxt You also need to install sass to override some style for the form inputs that you will use later So run the following command to install it yarn add dev sass sass loader Contact ComponentThis component is the simplest of the four Here the customer has to write their email address Then the email will be validated and if everything is valid the customer can go to the next step First you have to add a new state and a new mutation to the cart store Open the store cart js file and update the state function and the mutations as the following export const state gt cart email null export const mutations SET CART state cart SET CART EMAIL state email state email email You can now save the customer s email to the store and retrieve it later whenever necessary Next create the file components Checkout Steps Contact vue

component created previously Inside it there is a short form with only one input field to validate the email and a submit button If the form is valid it will call the submitHandler method which will commit the cart SET CART EMAIL mutation to update the customer email on the cart store Later on the email will be sent to the Medusa server to associate it with the cart This method also emits an event to call a function on the parent component lt checkout flow gt to update the visibility for the current component and the next one This component will also be marked as completed Address

emit updateSteps this step lt script gt Similarly here you use the checkout step component but this time inside you will find a long form with several form inputs that will allow you to get the info to fill up the shipping address object needed to update the cart on the Medusa server If the form is submitted and valid it will call the submitHandler method which will dispatch the next action to the cart store defined in store cart js In that action you are sending a POST request to the endpoint store carts cartId with the customer s email and shipping address On the Medusa server a new address will be created and associated with the customer s cart Then when the response from the server is received a mutation is committed to update the cart info in the store Lastly the submitHandler function will emit an event to update the visibility for the address component and mark it as completed Delivery ComponentAfter the cart is updated with the customer s address you should display the shipping options to the customers so they can choose their preferred option To be able to do that add the next state mutation and action to the cart store in store cart js export const state gt shippingOptions export const mutations SET SHIPPING OPTIONS state shippingOptions state shippingOptions shippingOptions export const actions async getCartShippingOptions state commit const data shipping options options await this axios shipping options state cart id commit SET SHIPPING OPTIONS options In this action you are sending a GET request to the endpoint store shipping options cartId that responds with an updated list of shipping options Then when the response is received a mutation is committed to update the shipping options in the store These shipping options are rendered in the component you ll create next to allow the customer to choose one Create the file components Checkout Steps Delivery vue with the following content lt template gt lt checkout step title Delivery method

cart cartCurrencyCode shippingMethod cart shippingMethod created this store dispatch cart getCartShippingOptions methods formatPrice lt script gt When this component is created it dispatches the getCartShippingOptions action to fetch all the shipping options Then you loop the shippingOptions array to show the list to the customer When the list is rendered and the customer clicks on one of the available options an action is dispatched on the cart s store to add that option as a shipping method to the current cart Finally the form input button emits an event to update the visibility of the delivery component and mark it as completed Next add the next action in the cart s store located in store cart js export const actions async addShippingMethod state commit optionId const cart await this axios post carts state cart id shipping methods option id optionId commit SET CART cart You send a POST request to the endpoint store carts cartId shipping methods that creates a shipping method based on the shipping option chosen and associates it with the customer s cart Then add the shippingOptions and shippingMethod getters in store cart js to retrieve that info in an easy way export const getters shippingOptions state gt state shippingOptions shippingMethod state gt state cart shipping methods shipping option id Payment Component with StripeThis component is the last thing to implement in the checkout workflow In this step you first show a list of available payment providers so customers can choose one Once the payment provider is selected you need to initialize a payment session so you can process the payment Create the file components Checkout Steps Payment vue with the following content lt template gt lt checkout step title Payment show success icon

changes on the selected provider methods TODO add show UI provider and process payment methods lt script gt The providers computed property is used to fetch the providers and render them in the template section The watcher function isOpen is in charge of dispatching the cart createPaymentSession and cart setPaymentSession actions For this to actually work you need to add the cart paymentProviders getter and the cart createPaymentSession and cart setPaymentSession actions in store cart js export const getters paymentProviders state gt state cart payment sessions export const actions async createPaymentSession state commit const cart await this axios post carts state cart id payment sessions commit SET CART cart async setPaymentSession state commit providerId const cart await this axios post carts state cart id payment session provider id providerId commit SET CART cart The paymentProviders getter is to quickly retrieve the payment sessions array from the cart s store The createPaymentSession action sends a POST request to the endpoint store carts cartId payment sessions This initializes the payment sessions array in the cart object received The setPaymentSession action sends a POST request to the endpoint store carts cartId payment session to set the payment session property in the cart if there isn t one already set or if the customer changes payment providers You will now use the Stripe provider module that you installed previously for this Nuxt js storefront This is where the actual integration with Stripe happens So when customers choose a payment provider the click event sets the provider prop to that value If the provider is stripe you create a card element that the customer uses to enter their card information To achieve that replace the TODO comment in watch with the following provider val if val stripe this showStripeCard Then add this function to the methods property methods showStripeCard const elements this stripe elements const card elements create card card mount stripe container this card card You watch for changes in the provider prop If its value is stripe you run the showStripeCard method that uses the Stripe module to create an elements object Then you create a card element to be mounted on a div container Finally you assign the created card to the card prop You will use it later to make the payment and complete the cart Next you need to add the function that will be called by the form input to process the payment Inside the methods property add the following method async processPayment if this provider stripe await this store dispatch cart setPaymentSession this provider const error await this stripe confirmCardPayment this store getters cart clientSecret payment method card this card billing details email this email if error this errors error message if error const id await this store dispatch cart completeCart this router push order summary id Here the setPaymentSession action updates the payment session object in the cart object to include data related to Stripe This includes the payment intent and client secret Finally the line this router push order summary id function redirects the customer to an order summary page where they see the order details for the completed cart To get the client secret quickly from the cart add a clientSecret getter to the getters object in store cart js export const getters clientSecret state gt state cart payment session data client secret null To confirm a card payment you use this stripe confirmCardPayment This method requires two parameters the first one is the client secret that you can get from the customer s cart and the second one is the payment method object that includes the card element and the billing details object with at least the customer s email When that method is executed you can receive a successful response or an error If you get an error you need to update the errors variable to show the message to the customer Otherwise the remaining dispatch actions will be dispatched The cart completeCart action is run if the payment is confirmed successfully so to complete the cart add the following action in store cart js export const actions async completeCart state commit const type data order await this axios post carts state cart id complete if type order
