海外TECH	DEV Community	Monitor your Spring Boot application with OpenTelemetry and SigNoz	https://dev.to/signoz/monitor-your-spring-boot-application-with-opentelemetry-and-signoz-1n4b	Monitor your Spring Boot application with OpenTelemetry and SigNozOpenTelemetry is a vendor agnostic instrumentation library In this article let s explore how you can auto instrument your Java Spring Boot application with OpenTelemetry and get the data reported through SigNoz an open source APM and observability tool Steps to get started with OpenTelemetry for Spring Boot applicationInstalling SigNozInstalling sample Spring Boot appAuto instrumentation with OpenTelemetry and sending data to SigNoz Installing SigNozYou can get started with SigNoz using just three commands at your terminal if you have Docker installed You can read about other deployment options from SigNoz documentation git clone cd signoz deploy install shYou will have an option to choose between ClickHouse or Kafka Druid as a storage option Trying out SigNoz with ClickHouse database takes less than GB of memory and for this tutorial we will use that option When you are done installing SigNoz you can access the UI at http localhost The application list shown in the dashboard is from a sample app called HOT R O D that comes bundled with the SigNoz installation package SigNoz dashboard Installing sample Spring Boot appFor this tutorial we will use a sample Spring Boot application built using Maven You can find the code for the application at its GitHub repo Steps to get the app set up and running Git clone the repository and go to the root foldergit clone cd spring petclinicUpdate PortThis app runs on port by default But port is used by SigNoz for its query service so let s update the port number to something else Open the application properties file located at spring petclinic src main resources and update the server port attribute database init supports mysql toodatabase hspring datasource schema classpath db database schema sqlspring datasource data classpath db database data sql Webspring thymeleaf mode HTMLserver port JPAspring jpa hibernate ddl auto nonespring jpa open in view false Internationalizationspring messages basename messages messages Actuatormanagement endpoints web exposure include Logginglogging level org springframework INFO logging level org springframework web DEBUG logging level org springframework context annotation TRACE Maximum time static resources should be cachedspring resources cache cachecontrol max age hAlso update the port number in petclinic test plan jmx located at spring petclinic src test jmeter to port number It will appear under PETCLINIC PORT elementProp Run the applicationRun the application using the following commands mvnw packagejava jar target jarYou can now access the application UI here http localhost Sample Spring Boot application running in your local hostOnce you ensure that your application runs fine stop it with ctrl z on mac as we will be launching the application with the Java agent downloaded from OpenTelemetry Auto instrumentation with OpenTelemetry and sending data to SigNozFor 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 Java JAR agent Now you need to enable the instrumentation agent as well as run your sample application You can do so by the following command OTEL METRICS EXPORTER none OTEL EXPORTER OTLP ENDPOINT http lt IP of SigNoz gt OTEL RESOURCE ATTRIBUTES service name javaApp java javaagent path to opentelemetry javaagent all jar jar target jarAs you are running this on your local host you need to replace lt IP of SigNoz gt with localhost The path should be updated to where you have kept your downloaded Java JAR agent Your final command will look like this OTEL METRICS EXPORTER none OTEL EXPORTER OTLP ENDPOINT http localhost OTEL RESOURCE ATTRIBUTES service name javaApp java javaagent Users Downloads opentelemetry javaagent all jar jar target jarNote the path is updated for my local environment Check out the Spring Pet Clinic app at http localhost and play around with it to generate some load It might take minutes before it starts showing up in the SigNoz dashboard Below you can find your javaApp in the list of applications being monitored javaApp in the list of applications monitored Metrics and Traces of the Spring Boot applicationSigNoz makes it easy to visualize metrics and traces captured through OpenTelemetry instrumentation SigNoz comes with out of box RED metrics charts and visualization RED metrics stands for Rate of requestsError rate of requestsDuration taken by requestsMeasure things like application latency requests per sec error percentage and see your top endpointsYou can then choose a particular timestamp where latency is high to drill down to traces around that timestamp View of traces at a particular timestampYou can use flamegraphs to exactly identify the issue causing the latency Flamegraphs showing exact duration taken by each spans a concept of distributed tracing ConclusionOpenTelemetry makes it very convenient to instrument your Spring Boot application You can then use an open source APM tool like SigNoz to analyze the performance of your app As SigNoz offers a full stack observability tool you don t have to use multiple tools for your monitoring needs You can try out SigNoz by visiting its GitHub repo SigNoz signoz SigNoz helps developers monitor their applications amp troubleshoot problems an open source alternative to DataDog NewRelic etc Open source

海外TECH	DEV Community	Building a Resilient Design System	https://dev.to/litmus-chaos/building-a-resilient-design-system-57gf	Building a Resilient Design System About the blogThis blog will talk about the journey of creating a design system which brought a uniformity in all our designs and helped in productivity What is a Design SystemWorking in software development and design we are often required to ship one off solutions In some cases we re working inside time limitations and here and there we simply haven t yet settled upon a way ahead These one off solutions are not always bad but if they are not made on some strategy or foundation we may end up in technical and design debts Design Systems have been characterized numerous ways an assortment of visual resources an example library and a CSS Framework are the most widely recognized However it s defined as a collection of related yet independent components that can improve product development efficiencies and help enable a great customer experience Design has always been largely about systems and how to create products in a scalable and repeatable way A universal Design framework is fundamental for building better and quicker better in creating a cohesive user experience and quicker on the grounds that it s anything but a typical language to work with Why we need Design Systems Faster time to marketA Design System dispenses reinvent the wheel every time a designer or developer sits down to work on a frontend element Either the library of assets will have a component that can be promptly utilized or the available guidelines will take care of some of the brainstorming Also since debates are more averse to happen organizations can deliver products a lot quicker than without a design system Besides the Design System evolves with time So if some team comes across a problem during advancement they modify the design system accordingly This prevents different teams from running into comparative issues later on Enhanced CollaborationIn the absence of a regulated set of guidelines designers and frontend developers often find it difficult to agree on multiple grounds Designers on occasion would design something without contemplating the functionality and implementation perspectives and basically hand over the plans to designers And afterward now and then engineers may present a couple of changes in the plan to deal with functionality With a design system you get to leave all these issues behind The Design System deals with aesthetics just as functionality and guarantees designers and engineers run after a shared objective Reduced costs and fewer errorsWith a faster turnaround time and fewer elements to create from scratch we can save some valuable design and development hours which can be otherwise used for productive tasks And since a design system is constantly used by multiple teams and individuals it s much easier to isolate errors at an early stage And with every error isolation the design system leaves lesser room for errors and streamlines frontend development Getting StartedTo work through these challenges and keep our decision making process fast I was teamed up with some front end developers at ChaosNative who explained to me how react theming works and all sorts of programming constraints We cleared our calendars and for around three weeks looking through all the designs of each product we jotted down the common elements the coloring schemes and then planned in creating the design system Laying FoundationWhile looking through the designs of each product I became aware that in designs various things are common like buttons input fields only they look different due to their colors or the icons used and many other things So we needed to bring a common ground for all these things and created a color system shadows and iconography Creating the componentsThere can be many components and developers may be creating the same components with different coding styles So after discussing with the front end developers they suggested to use a common JS library package and we decided on Material Design and after reading through its component style guide it became easy to know which components we definitely needed to create and assign the properties and make variants Compiling the libraryWhile creating these components we collected them in a master file called the Litmus Component Library which we referred to throughout the design process After a week or two we began to see huge leaps in productivity by using the library when iterating on designs It has also become a guidance for upcoming design of products ConclusionWe knew that this was a challenging project It meant re designing and rebuilding the majority of the views in our software As with any project there are things we wish we would have done differently While this was a monumental task that ended up requiring efforts from many of our product teams we found that creating our Design Language System was worth the investment and a huge leap forward Since the design language and code are often shared we can now build and release features on all native platforms at roughly the same time Development is generally faster since product engineers can focus more on writing the feature logic rather than the view code Additionally engineers and designers now share a common language I believe that aided with these systems we were able to focus more on actual user experiences and concepts we want to create in the future ResourcesTo view the design file with
