海外TECH	DEV Community	How we used DORA metrics to boost deployments, increase automation and more	https://dev.to/ghostinthewire5/how-we-used-dora-metrics-to-boost-deployments-increase-automation-and-more-dd9	How we used DORA metrics to boost deployments increase automation and moreIn I started wondering how I could measure the overall improvements in performance in the engineering department We were in the early stages of a program of work called North Star North Star was all about making engineering capability more efficient and flexible in responding to the business needs After researching various options we decided on the DORA metrics They provided us with all the necessary insights to track our success and benchmark ourselves against a definition of good What is DORA DORA is the acronym for the DevOps Research and Assessment group they ve surveyed more than technical professionals worldwide to better understand how the technical practices cultural norms and management approach affect organisational performance Take a dive into the latest DORA Report and in the book that summarizes the findings Accelerate What are the metrics we are using Cycle Time Time between the first commit on a merge request to master and production deployment Deployment Frequency Deployment Frequency helps identify the rate at which you are delivering new business value to your customers Smaller deployments have less risk of going wrong and provide an opportunity to deliver value to your customers in shorter iterations allowing you to learn quicker  Change Failure Rate For the primary application or service you work on what percentage of changes to production or released to users result in degraded service e g lead to service impairment or service outage and subsequently require remediation e g require a hotfix rollback fix forward patch  Throughput Detecting Burnout Throughput gives us a sense of the team s bandwidth It gives us a picture into how much work we can typically accomplish Teams should aim for consistent throughput  How do we understand the metrics Cycle Time Reducing amount of blockers for developers Deployment Frequency Limiting amount of code going to production at once limited batch size  Change Failure Rate Improving quality focus part of our Continuous Testing Strategy  Throughput Detecting Burnout Paying back technical debt amp introducing automation to reduce toil Following the rules of lean Optimize Work In Progress Cycle Time  Value is only released to production once it leaves the factory floor Deployment Frequency  Practice Kaizen Change Failure Rate  Invest in SRE DevOps automation Throughput Detecting Burnout  How are the metrics used internally The dashboard is regularly reviewed by the senior engineering management and are discussed and reviewed in our monthly town hall meeting and our fortnightly Ops Review Each team is encouraged to reflect on the metrics as they plan their work and consider improvements they could introduce The metrics also influence the decisions and prioritisation Just as importantly they help us to transform our company culture In terms of changes measured Cycle Time as we have not measured it before the main benefit for us is understanding what we need to improve In this actually increased to days due to reasons but we are currently in the area of days on average for  Deployment Frequency was improved from once a week to once every days x Increase   Change Failure Rate was about before we started it is now oscillating between Decrease  Throughput Detecting Burnout as with Cycle Time we have not measured it before the main benefit for us is understanding what we need to improve The throughput per developer per week increased by however we know why this is new ways of working additional code bases etc We are still keeping a close eye on this to ensure it returns to healthy levels which so far in it is  The main cultural changes were We have automated the majority of our deployment pipelines Using GitHub Actions  We have moved the bulk of our infrastructure management to a standardised Infrastructure as Code mainly Terraform  We have improved our Quality Assurance amp Testing process  We hold the ambition to join the elite performing group of organisations as defined by the State of DevOps report Each day brings us closer to that goal  What are our future plans On the technical side we are working to improve automation of the CI CD pipelines testing process amp Observability On the DevOps DORA culture side we are providing regular talks and training to wider audiences not only engineering to establish DORA as a reference point in future product development We are also making it a key point of our new consolidated engineering strategy I ve found the DORA metrics helped us improve our software development and delivery processes With these findings organisations can make informed adjustments in their process workflows automation team composition tools and more I recommend you try this in your organisation too

海外TECH	DEV Community	Getting Started with Eclipse Jifa	https://dev.to/qainsights/getting-started-with-eclipse-jifa-218g	Getting Started with Eclipse JifaI have been posting multiple videos about the Performance Engineering Series on QAInsights channel which will help you to get started with troubleshoot Java applications In this blog post we are going to see how you can use Eclipse Jifa to identify potential performance bottlenecks in your Java applications Let us get started Eclipse JifaEclipse Jifa Java Issue Finder Assistant is an open source application to troubleshoot Java applications The inception phase of Jifa was back in by Alibaba under the Eclipse Foundation Developers from Netflix Alibaba Cloud and other developers are contributing to Jifa project Jifa is a scalable web based application easy to deploy and maintain Right now it supports the following analysis Heap Dump Thread Dump an enterprise feature and GC Log Jifa s frontend is Vue backend is Eclipse Vert x Jifa s analytical engine consists of Heap Dump service and GC Log Analyzer Scalability can be achieved by deploying Jifa in a Master Worker fashion also known as the Map Reduce pattern Most of the performance testing tools use this technique to generate more load for the target application InstallThere are multiple ways you can follow to install Jifa The easiest way is to run the docker container using the below command docker run p jifadocker jifa worker demoJifa also supports Kubernetes and Master Worker patterns for scalability or you can build the artifacts using Gradle and deploy For personal use I d recommend docker mode For enterprise use please use Master Worker or Kubernetes patterns for the enterprise features Master Worker DeploymentBefore you get started please make sure you have nodejs npm Gradle and JDK is installed git clone gradlew buildJifacd jifa deploy default pattern deploy jifa shLaunch Jifa Home PageIf you want to deploy only the workers use the below commands cd deploy deploy worker shLaunch In Master Worker mode master node routes the user requests from the client to the workers and schedules new workers on demand worker nodes perform the analysis Kubernetes cd scripts docker images build image shcd cd deploy ks pattern deploy shLaunch localhost Jifa Enterprise FeaturesIn Kubernetes mode workers can be orchestrated based on the analysis tasks To release a pod click on release button Release WorkerHeap Dump AnalysisLet us upload a sample heap dump to Jifa and play around with the features There are multiple ways you can generate a heap dump In this demo I am going to upload a heap dump from JMeter But you can upload any heap dump you want Launch Jifa click on Heap Dump Analysis gt Add Heap Dump file to upload the file Upload Heap DumpJifa supports various sources such as S OSS URL SCP or local for upload the file Drag and drop the heap dump file OpenJDK HPROF format or click the Upload icon to upload Click analyze to get started Check keep unreachable objects and click Confirm AnalyzeOnce the analysis is complete Jifa will display all the details Jifa AnalysisThe analyzed information might be familiar if you are familiar with Eclipse MAT Jifa uses Eclipse MAT under the hood for Heap dump analysis to detect memory leaks for better performance The following are the features of Heap Dump Analysis in Jifa OverviewLeak SuspectsGC RootsDominator TreeClass HistogramUnreachable ObjectsDuplicated ClassesClass LoadersDirect Byte BufferSystem PropertyThread InfoOQLOther featuresJifa features an inspector panel where the search using the object address is possible to dive into the respective object The Inspector panel can be toggled on off under Settings Thread Dump AnalysisGo to Jifa home page and click on Thread Dump Analysis to upload a sample thread dump Analyze the thread dump to view the output Thread dump analysis helps to identify issues like thread locks deadlocks to understand threads state and more Thread Dump AnalysisThe following are the features in Thread Dump Analysis Basic InformationThread OverviewThread Group OverviewJava MonitorStack TraceRaw contentGC Log AnalysisGarbage Collection Log analysis helps to optimize GC settings memory management and more To generate a GC log pass the verbose gc Xlog gc file gc log to the JVM arguments for Java or above This will generate a GC log in the current directory Upload gc log to Jifa to analyze Jifa supports the following for GC log analysis OpenJDK and Serial GC Parallel GC CMS GC G GC ZGCGC Log AnalysisThe Overview tab features the problems and suggestions metadata and Key Performance Indicators Graph tab features visualizations about GC count pause time heap and more GC GraphsGC Cause and Phase displays about GC activities such as Full GC Young GC and more and the pie chart GC Cause and PhaseGC Detail tab helps to filter the GC events log time and more GC DetailConclusionJifa is a great tool to identify potential memory leaks thread issues for Java applications If you do not have the ability to install GUI based tools like MAT VisualVM or if you do not have high memory to process large dump files then Jifa can help you Jifa supports multiple sources to upload the dump log file Jifa user interface is intuitive and easy to navigate But navigating tree structure is cumbersome GC Log analysis in JIFA provides problems and suggestions But for heap dump and thread dump you need to wear a detective hat to troubleshoot the problems	2022-02-28 16:06:39
