Which all metrics needs to be monitored for restful webservices? 1. Response Time: Measure the time taken to process incoming requests and generate responses. Monitor average response time, percentiles (e.g., 90th, 95th, 99th), and trends over time to identify performance issues and bottlenecks. 2. Throughput: Monitor the rate of incoming requests and processed responses. Measure request and response rates per second or minute to understand traffic patterns, peak loads, and capacity utilization. 3. Error Rate: Track the percentage of requests that result in errors or failures. Monitor HTTP status codes (e.g., 4xx, 5xx) and error responses to identify issues such as client errors, server errors, or network issues. 4. Availability: Monitor the uptime and availability of the web service. Track service availability over time and calculate uptime percentage to ensure that the service meets reliability requirements and SLAs. 5. Latency: Measure network latency between clients and the web service endpoints. Monitor round-trip latency, DNS lookup time, TCP connection time, and time to first byte (TTFB) to identify network-related issues and optimize performance. 6. Concurrency: Monitor the level of concurrency or concurrent connections to the web service. Track the number of active connections, connection pool usage, and queue length to ensure that the service can handle concurrent requests efficiently. 7. Cache Hit Ratio: If caching is implemented, monitor the cache hit ratio to assess the effectiveness of caching strategies. Track the percentage of requests served from the cache versus the origin server to optimize cache performance and reduce response times. 8. API Usage Metrics: Monitor usage patterns and trends of API endpoints. Track the frequency of API calls, resource usage (e.g., CPU, memory), and API usage quotas to understand usage patterns and plan for capacity scaling. 9. Security Metrics: Monitor security-related metrics such as authentication failures, unauthorized access attempts, and anomalous behavior. Track security events, audit logs, and compliance metrics to ensure data protection and regulatory compliance. 10. Dependencies: Monitor dependencies and third-party integrations used by the web service. Track availability, latency, and error rates of external services, databases, and APIs to identify dependencies that may impact service reliability or performance. CONCLUSION:- By monitoring above mentioned metrics, issues can be detected, performance can be optimized, and ensure the reliability and availability of their RESTful web services. Some common tools available for monitoring these restful api are available like Prometheus , Grafana and many other. #backendEnineering #apis #systemdesign

Immediate Reaction of Layoffs is Imposter Syndrome ! If you got impacted by layoffs at Intuit or Zoom or any other company, remember 1. There are so many reasons a company has to do layoffs. It’s part of business and mostly not related to your performance. 2. If you were marked Under Performer in last few Appraisal Cycles - there could be multiple reasons for that.. poor leadership, high complexity, bad environment, lack of learning, personal situation etc etc and not all of these would be in your control. So, give yourself a Benefit of Doubt and Keep Going 🙌 Not all Companies are same..Not all Managers are same..Not all projects are same. Things will work out for sure 👍

🚨 IMP Update: In Chrome 131, there is a new setting has been introduced due to which SelectorsHub #Debugger feature stopped working. To use SelectorsHub Debugger feature from Chrome 131 onwards, you need to do small setting in chrome DevTools. Without this setting it won't work. Special thanks to Gaurav Khurana for finding this quick fix. Please follow this video for the setting change- https://lnkd.in/gX3DwZa8 #selectorshub #update #debugger

Hi Google Tech Team, I have been using Google Pay for a long time but 6 months ago, I deleted my Google Pay Account and then recreated with the same mobile number & same email address. After that, I am unable to fetch my credit score from Google Pay Application. Like, I am getting an error 'Cannot fetch credit report with this Google Pay account. If you have different accounts with the same phone number, sign in to the account you used previously and try again', while trying to access my credit report. As per the error message, how can I login to the previous account if I have used the same mobile number and email address in the new Google Pay Account. Logically, if somehow the details of old account data is still available in your database even though I have permanently deleted it from my end then it should not allow me to recreate a new account using the same mobile number or email address. Please have a look into this issue and fix it if it's a bug. #google #googlepayservices

Harnessing Simple Concepts for Complex Solutions: An episode from my career 🚀 In #engineering, sometimes the simplest ideas provide the keys to solving the most intricate problems. This was strikingly evident in one of my notable projects at Expedia Group back in 2019, where a fundamental concept from operating systems—locks—became the cornerstone of a high-stakes #solution. Faced with the challenge of ensuring no customer was charged twice in a high volume-low latency payment processing system that handled billions of dollars in transactions, I turned to this basic yet powerful principle learnt during my bachelors and masters days at Manipal Institute of Technology and Indiana University Bloomington respectively. Despite its simplicity, the concept of locks is often overlooked in its potential to address large-scale challenges efficiently. By custom-designing a lock manager tailored for a distributed system running on Amazon Web Services (AWS), we implemented a solution that not only prevented duplicate transactions but also scaled seamlessly across multiple nodes. This system needed to distribute loads effectively while maintaining transactional integrity—tasks that the custom lock manager handled with precision. This project underscored a vital lesson: great engineering does not always come from complexity. Often, it's about applying straightforward, well-understood principles in innovative ways to create solutions that are not just effective but also robust and scalable. 🌟 Keen to delve deeper into software engineering or refine your #interview skills?

🎄New Blog ! Recently, I have been experimenting a lot with Istio Service Mesh. Now that Istio Ambient Mesh has been released, it was high time that I do my bit of self-exploration of the same. The long weekend seemed perfect for this :) In this blog, we setup our home Kubernetes cluster and start exploring the Istio ambient mesh. The focal point of this new dataplane mode is that it is a sidecar-less model and hence the fat cash savings we have against compute power and cloud bills. In Part 1, we explore the traffic flow via L4 ztunnel - a major component of ambient. In subsequent parts, we will explore more of L7 waypoint proxy. Blog has been stuffed with memes to enjoy the process :) Blog link: https://lnkd.in/gdXa5w5v GitHub link for manifests: https://lnkd.in/gTbQC47g #istio #kubernetes #blog #ambient #ztunnel #waypoint

🌍 Roadmap to Becoming the 3rd Largest Economy: India’s journey to surpass Germany and Japan as the world’s third-largest economy is no longer an uncertainty—it’s only a matter of when, not if. Achieving this aligns with PM Narendra Modi’s promise to make India the largest economy by the end of his third term in 2029 📈 At a 6% growth rate, India is poised to reach this milestone by 2028-2029. 🚀 A consistent 8% growth will accelerate this timeline to 2026-2027. 🔥 With an ambitious 10% growth, India could overtake by 2025. 💰 For #India to truly challenge #China’s dominance, we’ll need a substantial financial boost—around $100B annually for strategic assets like ports and airports. Without this, we risk becoming #America's Ukraine in Asia, a role better suited for #Taiwan, #Philippines, or #Japan. 🔑 To lead globally, India must combine its economic growth with bold investments and strong partnerships.

Swiggy used RAG to build its in-house Text-to-SQL -- allowing all employees to make data-driven decisions faster. 📈 Here’s how they built the system end-to-end: Suppose a user types a question in Slack, like "What's the average delivery time in Delhi last week?" The query passes through AWS Lambda, where a function cleans and formats it before sending it to the LLM. The model then checks the Knowledge Base for metadata related to “delivery time”, which includes tables and columns relevant to delivery data. It identifies “average delivery time” as the metric and retrieves relevant historical SQL examples. Using Swiggy-specific metadata, it selects tables like Orders and columns like delivery_time. The model also uses few-shot learning by adding reference queries from similar past requests to guide the SQL generation. Finally the generated SQL query is run on Snowflake, and gets adjusted if errors occur. The final query output is sent back to the user on Slack. Users can rate accuracy, helping refine the model. Link to the full article is in the comments. #AI #LLMs #RAG #SQL

In today's era of hybrid and remote work, it's ironic how some companies shell out 5+ lakhs a month for managers but hesitate to trust them to lead a small team from home this raises an important question if they are valued enough to manage a team in-office why not remotely? paying high salaries should imply confidence in managers skills, strategic thinking, and independence. Yet, the reluctance to trust them with remote work points to a broader issue perhaps companies are hiring managers to be supervisors not leaders if an organization invests in leadership roles but insists on keeping them within sight to ensure work is getting done, there’s a disconnect somewhere. As the world shifts towards hybrid and remote work, it's disheartening to see that in Pakistan many companies still expect employees to show up in the office, even when the work environment is increasingly hazardous. It is especially frustrating when companies promote their “care programs” but don’t practice what they preach. Health risks, whether from pollution, seasonal diseases, or overall work stress, are real, yet employees are often expected to be physically present without regard for their well-being. #workfromhome #lahore #airpollution #wfh

A post by X user Naveen Kopparam has gone viral, revealing that a dosa seller near his home earns over ₹20,000 daily, totaling ₹6 lakh a month, and takes home ₹3-3.5 lakh after expenses—all without paying income tax. This sparked debates on social media about the disparity between vendors and salaried employees in India. Kopparam noted that while the vendor pays no taxes, a salaried employee earning ₹60,000 monthly pays 10% as tax. The post raised broader concerns about income tax policies and tax evasion, with users questioning similar practices by professionals like doctors and traders. #ViralPost #DosaSeller #StreetFoodIndia #SocialMediaDebate #IndiaEconomy #EarningsDisparity #SmallBusinessStories #marketinggrowmatics #smallbusiness #smallbusinessowner #startups

Jio to Revolutionize Cloud Storage: 100GB Free for Everyone! In continuation to challenge the large Western counterparts Reliance Jio's cloud storage offer could undercut Google One and iCloud pricing.The competition could also nudge these players to lower their pricing - Google One (100GB at ₹130), iCloud (50GB at ₹75) - a trend emerging as Indian players like Ola, and MapMyIndia already started it. Jio has brought a very lucrative proposition for an average phone user in India who struggles to upgrade memory because of paid storage. But, bundling of products and services with the OS ecosystem is a key challenge here.  For instance, WhatsApp or the majority of app data is currently backed up in iCloud and Google One. Competition Commission of India added there has to be some push for the policy side as well to make the tech ecosystem a level-playing field. #JIO #cloudstorage

Layoffs in past have proved that An average engineer in a high priority team is more valuable than a top engineer in a low priority team. Most of the layoffs are not relevant to performance but have a direct correlation with the projects team is working on. It is equally important to pick the right team along with the company. #softwareengineering #layoffs #programming

***** Frontend roles are not on raise ***** Backend roles are not on raise ***** QE roles are not on raise ***** Dev-ops roles are not on raise In short, the number of openings are not increasing in high numbers since the beginning of 2024, I don't see them getting increased in any near future. Does that mean you should worry ? "No, try becoming a Software Engineer from developer. Quality Engineers will continue to have demand and mediocres will be wiped away" Don't end up spending money on anything/anyone who says openings will increase and pay me and I will assist you.
