海外TECH	DEV Community	Add Umami Analytics to a Web Application	https://dev.to/documatic/add-umami-analytics-to-a-web-application-4h36	Add Umami Analytics to a Web Application IntroductionAnalytics plays an important role in knowing the user and the performance of a website People ask me about my audience s country and views for sponsored posts on my website So knowing your audience is always a plus point Analytics can also be helpful in knowing your least and best performing page article You can work on the least one to improve it Google Analytics is a fantastic tool to know your traffic but it s better for non developer people to add analytics Umami is a self hosted web analytics solution that is open source and privacy focused You can customize the database and hosting as per your need The feature that impresses me is that with one click you can get a shareable link to the analytics for sharing That s why Hashnode uses Umami to provide article analytics to users A solid reason to at least give it a try So today we are going to look into adding analytics to a web application with Umami We are going to cover the following topics Installing UmamiSetting up databaseDeploying Umami to VercelAdding a script to our web pageCollecting the dataThe topics look a lot but the setup is quite easy if you are familiar with web development So let s get started with it Prerequisite and environment setupThe guide is simple but you need to have at least basic knowledge of web development and GitHub We are going to code anything but this will help you understand it better As for the tools we need to have the following tools pre installed Git It is a distributed version control system This will help fork the Umami repository and push code to GitHub for deployment on Vercel Node It provides you with a JavaScript runtime environment We will use this for installing dependencies and running the Umami server locally Umami needs yarn for installing the package npm might give some error After installing Node you can run the below command to install the yarn globally Enter the command in the terminal npm install g yarn Installing UmamiNavigate to the directory in which you want to create the project and open the terminal to enter the below command one by one in the terminal This will fork a repository from GitHub git clone https github com umami software umami git cd umami yarn installThis will install the dependencies of our Umami server DatabaseWe need to have a database to store user and analytics details Umami supports SQL and PostgreSQL for databases We are not going to use any local database we are going to use PostgreSQL from the supabase It provides an all in one solution to the backend having support for Database Authentication instant APIs Edge Functions Realtime subscriptions and Storage Now go to their website through supabase com and click on Start your project After registering logging in you will be redirected to their project page Here click on New project to create a new project You will redirect to Create a new project page Fill in the details related to the project Note The password section does not support some special characters So avoid using them You can use their Generate a password to generate a strong password that will not have any errors Now after creating the project then click on Setting from the left panel Then select Database and scroll down to the bottom to find the Connection string The connecting string will look like postgres postgres YOUR PASSWORD host postgres Replace the YOUR PASSWORD with the project s password and add pgbouncer true at the end Now back to the code editor Create a env file at the root and add two environment variables DATABASE URL for adding the connecting string and HASH SALT for adding a random string for hashing This will make our env file DATABASE URL postgres postgres YOUR PASSWORD host postgres pgbouncer true HASH SALT any random stringNow it s time to create a build Open the terminal and run the below command to create a production ready build yarn buildThis will take some time after successfully creating the build Run the below command to start the umami server locally yarn startIf the server start running check it on the machine by going to http localhost By default the user will be admin and the password will be umami Enter the credentials for logging in After logging in change the password by navigating to Setting →Profile →Change password Now we are ready to deploy the umami web app to a hosting provider Deploying UmamiWe need to have our code in a repository either on GitHub GitLab or Bitbucket Choose whatever you feel comfortable with Push the code them You can check DigitalOcean s How to Push an Existing Project to GitHub guide to push code to GitHub As the Umami is made using NextJS it will be a better option to host it on vercel So we are going to host the umami web app on vercel Navigate to vercel com after registering login then click on Add new… then Project In the Import Git Repository page click on the option where you have pushed the code Then it might ask you for permission to access the repository provide that After this you will have your repository select the one where you have pushed the code Now you will be redirected to Configure Project Vercel will automatically detect the framework that is NextJS and will run the build accordingly we don t need to change anything from the Build and Output Setting We need to add the Environment Variables Click on it and add the environment variable that we have added in the env file initially After this click on Deploy to start the process of deployment After successful deployment visit the website and log in with the changed password If everything goes well you will be able to see the dashboard Now it s time to add a website and collect data Adding Website and Collecting DataOn your Umami s vercel page navigate to Setting →Websites → Add website for adding website for analytics Enter the required information on the webpage and configuration Let s look into the field one by one Name Enter a relevant name for the website Domain Enter the domain of the website This should not include the HTTP Owner When you will have multiple users this will be helpful to sort Initially select the admin Enable share URL Check this box for getting a shareable URL for the analytics Now click on Save to save the website This will result in the above screenshot Click on the code logo to get the code added to our website for data col collectionAdd the code to the Head section of the website for collecting the data After successfully adding the code and deploying your website you will be able to see the analytics in the dashboard section of the Umami Note To test the visit visit the website from another device from the same device it will not register the view Otherwise you can always check the website s code from the inspect tool of the browser ConclusionWe have gone from running Umami locally to deploying it on the web Once set up you won t need to do anything the data will be collected and display by the Umami It will show analytics for views visitors pages referrers browsers OS devices and countries with a map This variety of data will be enough to work on it Also you can always share these analytics with anyone with a link Umami also tracks events from your webpage It s also quite easy to set up You can look at the docs here for more information regarding event tracking I hope this article has helped you in knowing the Umami tool for analytical solutions Thanks for reading the blog post	2022-11-19 11:30:00
海外TECH	DEV Community	How I Fixed a Linux Disk Performance Issue In Minutes! - A Step by Step Guide to Optimizing Linux System	https://dev.to/howtouselinux/how-i-fixed-a-linux-disk-performance-issue-in-minutes-a-step-by-step-guide-to-optimizing-your-system-26o9	How I Fixed a Linux Disk Performance Issue In Minutes A Step by Step Guide to Optimizing Linux SystemI was recently tasked with solving a tricky disk performance issue on a Linux server At first I thought it would be a straightforward task After all I had been working in IT for several years and had seen my fair share of disk performance issues But as soon as I started looking into the issue I quickly realized that this wasn t going to be an easy fix There are disks on that Linux system and the disk performance seemed to vary from time to time I started by trying some of the more obvious solutions ーchecking disk space checking hardware status listing partitions checking RAID status etc But none of those seemed to be having any issues At this point I was beginning to lose hope But then I remembered something my mentor had said when I first started in IT “When all else fails go back to basics I decided to start from the very beginning I checked the physical connections of the disks making sure all cables were securely connected and in the right places Once that was done I followed the steps here to check disk performance I began running a monitor with the iostat command on each disk to see if I could identify any areas where performance might be suffering After a few hours I found one disk that had abnormally high latency After carefully examining the disk I was able to pinpoint a specific area where data transfers were taking much longer than usual After further investigation I realized that this issue was caused by a high workload on the disk The IOPS for that disk was increased by times and disk utilization was during the issue time Then I used the iotop command to check which process generated so much workload on this disk It was a process related to Database I checked this with the Database team It turned out that they added a SQL recently which trigged the full table scan on the database side They fixed this sql by adding an index on the DB side After that the latency dropped significantly and the overall performance of the disk improved drastically Problem solved It took me a few hours to fix the issue but in the end it was worth it I learned an important lesson that day Sometimes if you take the time to go back to basics and examine things from a different angle it can make all the difference Now I can proudly say that I have a deep understanding of disk performance in Linux and the skill set to tackle any issue that might arise And it all started with that one disk performance issue The moral of this story is simple don t give up With the right knowledge and approach any problem can be solved even those that seem impossible at first This was true for me when I faced my disk performance issue in Linux ーand it can be true for you too Good luck	2022-11-19 11:25:36
