It was the late nineties, and I had about 3-4 years of development experience by then. I had just transitioned from the GSM field to the world of network management systems (NMS) after joining a multinational company in Bengaluru. Although my master’s degree was in computer networks, NMS was entirely new to me. I was familiar with hubs, routers, switches, IP addresses, RFCs, and protocols, but only in theory. This was the first time I had hands-on experience with NMS.
From a technological standpoint, I was quite proficient. I coded in C++ and worked on HP-UX, a variant of UNIX. I had experience with large-scale, mission-critical systems. In a way, I was filled with youthful confidence when I began working with NMS.
In my new role, I was assigned the task of enhancing a log analysis tool as part of a larger NMS. NMS are structured around the FCAPS model, which stands for fault management, configuration management, accounting, performance, and security. This model is defined by ISO. The log analysis tool our team was developing fell under the fault management category. Figure 1 captures the arrangement.
The requirement was straightforward: the log analysis tool needed to gather system logs from all devices across the network, store them in a database, analyse them, and take necessary actions.
This NMS was intended for use by large service providers. In the US market, the adoption of GSM mobile phones was slower compared to VoIP (Voice over IP). While mobile telephony was just beginning in India, offices were transitioning from PSTN technology to VoIP, and VoIP phones were becoming commonplace on every employee’s desk. Each time a call was made or received, or a VoIP phone was powered on or off, a system log was generated. Our log analysis tool needed to collect and analyse all these logs.

Helgrind: Detecting Synchronisation Issues in Multithreaded Programs
Let's explore how Helgrind can be used to detect and debug multithreading issues with the help of a multithreaded C program.
The Perfect Process of Booting a PC
Booting a PC seems as simple as eating a cake. But are you aware of all that goes on behind-the-scenes to bake a delicious cake or seamlessly boot a PC?
Exploring eBPF and its Integration with Kubernetes
eBPF, a game-changing technology that extends the capabilities of the Linux kernel, offers significant advantages for Kubernetes networking. It also greatly improves Kubernetes observability by capturing detailed telemetry data directly from the kernel. Read on to find out how its integration with Kubernetes has immense benefits.
Deploying Generative AI LLMs on Docker
Built on massive datasets, large language models or LLMS are closely associated with generative Al. Integrating these models with Docker has quite a few advantages.
Containerisation: The Cornerstone of Multi-Cloud and Hybrid Cloud Success
Open source containerisation software provides the flexibility, cost-effectiveness, and community support needed to build and manage complex multi-cloud and hybrid cloud environments. By leveraging this software, businesses can unlock the full potential of multicloud and hybrid cloud architectures while minimising vendor lock-in risks.
From Virtual Machines to Docker Containers: The Evolution of Software Development
Containerisation and Kubernetes have eased software development, making it faster and better. Let's see where these are headed, looking at trends that are making life easier for developers.
India's Leap in Supercomputing: Innovating for Tomorrow
As India strides towards self-sufficiency in supercomputing, embracing this evolution isn't just an option-it is pivotal for global competitiveness and technological leadership.
SageMath: A Quick Introduction to Cybersecurity
In the previous articles in this SageMath series, we delved into graph theory and explored its applications using SageMath. In this seventh article in the series, it is time to shift our focus to another crucial subfield of computer science: cybersecurity and cryptography.
Efficient Prompt Engineering: Getting the Right Answers
OpenAl's GPT-3 and GPT-4 are powerful tools that can generate human-like text, answer questions, and provide insights. However, the quality of these outputs depends heavily on how you frame the input, or prompt. Efficient prompt engineering ensures you get the right answers by designing inputs that guide the AI towards relevant, clear, and useful responses. Let's find out how to craft effective prompts with examples.
Analysing Linus Torvald's Critique of Docker
This article looks at Docker's security flaws, particularly its shared-kernel model, and contrasts it with traditional VMs for better isolation. It discusses Linus Torvalds' concerns, explores mitigation techniques, and proposes a roadmap for building a more secure containerisation platform using hardware-assisted virtualisation, true isolation, and a robust orchestration layer.
