You’ve faced mysterious slowdowns and downtime in your application. Logs are scattered, metrics are basic, and you’re still left guessing what parts of your code are failing. Observability solves this by bringing together traces, metrics, and logs in...
In this blog, I’ll take you through the complete journey of building a multi-container application that displays Kubernetes pod logs using a Go backend, a web frontend, and a dashboard built with Builder.io. The idea started small: fetch and display ...
Hello everyone! A while back I passed my first cloud certification in the first attempt. To be honest I was super nervous putting all my knowledge at an official test. But in the end, it played out well. In this blog, I will introduce you to the cert...
Hey everyone! Welcome back 👋. In this blog, we will see what is FluentD and why we actually need it. To start with simple information, Fluentd comes under the "Observability and Analysis" part of the cloud-native application cycle and is very helpfu...

In this blog, I am not going to describe the common commands. Here I am going to tell you the commands which will help you stand out of the crowd using a command prompt
Most files in Windows are associated with a specific program that is assigned to open the file by default. At times, remembering these associations can become confusing. You can remind yourself by entering the command assoc to display a full list of filename extensions and program associations.
You can also extend the command to change file associations. For example, assoc .txt= will change the file association for text files to whatever program you enter after the equal sign.
Deleting files on a mechanical hard drive doesn't really delete them at all. Instead, it marks the files as no longer accessible and the space they took up as free. The files remain recoverable until the system overwrites them with new data, which can take some time.
The cipher command, however, wipes a directory by writing random data to it. To wipe your C drive, for example, you'd use the cipher /w:d command, which will wipe free space on the drive.
Drivers remain among the most important software installed on a PC. Improperly configured or missing drivers can cause all sorts of trouble, so it's good to have access to a list of what's on your PC. That's exactly what the driver query command does. You can extend it to driver query -v to obtain more information, including the directory in which the driver is installed.
You can use this command to identify differences in text between two files. It's particularly useful for writers and programmers trying to find small changes between two versions of a file. Simply type fc and then the directory path and file name of the two files you want to compare.
This command relays the IP address that your computer is currently using. However, if you're behind a router (like most computers today), you'll instead receive the local network address of the router.
Entering the command netstat -an will provide you with a list of currently open ports and related IP addresses. This command will also tell you what state the port is in; listening, established, or closed.
Typing ping followed by an IP address or web domain will send a series of test packets to the specified address. If they arrive and are returned, you know the device is capable of communicating with your PC; if it fails, you know that there's something blocking communication between the device and your computer.
This is a more advanced version of ping that's useful if there are multiple routers between your PC and the device you're testing. Like ping, you use this command by typing pathping followed by the IP address, but unlike ping, pathping also relays some information about the route the test packets take.
The tracert command is similar to pathping. Once again, type tracert followed by the IP address or domain you'd like to trace. You'll receive information about each step in the route between your PC and the target.
Powercfg is a very powerful command for managing and tracking how your computer uses energy. You can use the command powercfg hibernate on and powercfg hibernate off to manage hibernation, and you can also use the command powercfg /a to view the power-saving states currently available on your PC.
