The increasing complexity of systems, driven by the adoption of microservice architectures, widespread use of containerization and orchestration (Kubernetes) [1], as well as the deployment of hybrid and multi-cloud environments, imposes new and heightened requirements on monitoring systems. Against this backdrop of technological evolution, approaches to monitoring have changed significantly. Whereas earlier monitoring primarily focused on simple tracking of network device availability and CPU usage, today it involves the comprehensive collection and analysis of millions of metrics, logs, and traces in real time. Modern monitoring is no longer merely a tool for incident response but serves as a foundation for ensuring system resilience, guiding architectural decisions, and managing business-critical key performance indicators (KPIs). The aim of this study is to classify monitoring systems, conduct a systematic analysis of the current state, and identify key trends in the development of IT infrastructure monitoring systems. 2 Theoretical and Methodological Review To form a more complete and comprehensive understanding of the current state of the subject, as well as to identify major development trends, this study employs an integrated methodology based on a combination of analytical, comparative, and systemic approaches, alongside the review and synthesis of specialized academic and industry literature. SCIENCE AND INNOVATION INTERNATIONAL SCIENTIFIC JOURNAL VOLUME 4 ISSUE 12 DECEMBER 2025 ISSN: 2181-3337 | SCIENTISTS.UZ 99 A review of recent research in IT infrastructure monitoring indicates that the field is moving toward intelligent, proactive, and integrated approaches within IT management. Several studies [2] highlight the importance of a comprehensive approach to building monitoring systems, including a multi-layer architecture covering network components, servers, and application services. They emphasize the need to assess architecture in terms of scalability, reliability, compliance with load requirements, and the adaptability of ready-made solutions to enterprise-specific needs. Another line of research [3] focuses on the concept of proactive monitoring and IT infrastructure management. In these works, monitoring is considered not only as a means of detecting failures but also as a tool for forecasting and preventing incidents. Key tasks include time series forecasting, anomaly detection, root cause analysis (RCA), and decision-making based on precedents. This reflects a shift from reactive systems to proactive, AIOps-based approaches. Studies on the application of big data technologies [4] describe monitoring as part of the ecosystem of observability platforms. Authors emphasize the integration of machine learning methods and stream data processing, which allows for real-time telemetry analysis and the detection of patterns that are inaccessible to traditional analysis tools. Particular attention is given to data unification and open standards, such as OpenTelemetry. Some studies [5] also demonstrate the practical aspects of implementing intelligent monitoring systems based on network traffic analysis and adaptive classification algorithms. These studies confirm the effectiveness of using artificial intelligence methods for predicting and preventing failures, as well as the potential for scaling such solutions for large network infrastructures. 3 Analysis and Results With the increasing complexity of IT infrastructure, effective monitoring becomes critically important for ensuring system reliability and performance. Today, there is a wide range of monitoring tools that can be classified according to several key characteristics, reflecting their purpose, data collection methods, and architectural features: 4 1. By Purpose and Type of Collected Data  Metrics Monitoring focuses on collecting quantitative indicators that characterize system state: CPU usage, memory utilization, disk operation intensity, network latency, and queries per second (QPS). These data allow evaluating performance and timely identifying deviations in operation. Typical solutions include Prometheus [6], Zabbix, and Graphite.  However, numerical metrics alone are often insufficient for a comprehensive understanding of ongoing processes. In this case, Logging Monitoring comes to the forefront, focusing on the collection and analysis of structured and unstructured textual event messages. Logs provide context for errors, warnings, and administrative actions, making them indispensable for incident investigation [7]. Common tools include ELK Stack (Elasticsearch, Logstash, Kibana), Loki, and Splunk [8].  With the shift to microservices and distributed architectures, there is a need for more detailed analysis of interactions between system components. This task is addressed by Distributed Tracing, which allows tracking a request's path through multiple microservices, measuring its latency, and identifying bottlenecks. Classic tools in this area are Jaeger and Zipkin [9].  Complementing these approaches is Application Performance Monitoring (APM), which provides deep insight into the behavior of application code by tracking method execution SCIENCE AND INNOVATION INTERNATIONAL SCIENTIFIC JOURNAL VOLUME 4 ISSUE 12 DECEMBER 2025 ISSN: 2181-3337 | SCIENTISTS.UZ 100 times, SQL queries, and external API calls. APM systems not only help detect problems but also analyze their impact on business metrics. Well-known solutions include Dynatrace, New Relic, and AppDynamics [10].  2. By Data Collection Method From the perspective of how information about infrastructure state is obtained, monitoring systems can be divided into agent-based and agentless. Agent-based monitoring involves installing a specialized software component—an agent—on each monitored node, which collects, preprocesses, and transmits data to the monitoring server. This mechanism provides relatively high accuracy and flexibility in metric collection, as well as the ability to monitor parameters that are not accessible via remote polling. Examples of solutions implementing this approach include Zabbix Agent, Telegraf [11], and Prometheus Node Exporter. Agentless monitoring, on the other hand, does not require additional software installation on monitored devices. It relies on standard remote access and polling protocols, such as SNMP, WMI, SSH, or HTTP requests. This approach reduces the load on infrastructure and simplifies system deployment, making it especially convenient for monitoring network equipment, servers, and cloud services. 3. By Architectural Principle From an architectural standpoint, monitoring systems can be classified as monolithic or modular solutions. Monolithic systems are centralized “all-in-one” software suites, such as Zabbix [12]. They are characterized by reliability, relative ease of deployment, and operation; however, such solutions demonstrate limited scalability when operating in dynamically changing and distributed cloud environments. In contrast, modular and cloud-native systems (e.g., the combination of Prometheus + Grafana + Alertmanager) are built on the principle of independent yet interconnected components. This architecture provides high flexibility, extensibility, and resilience to infrastructure changes, making it particularly valuable in modern DevOps and container-oriented environments [12]. Thus, selecting an appropriate monitoring system requires a comprehensive approach that considers both monitoring objectives and infrastructure characteristics. An optimal solution often involves a combination of different tools that complement each other. Modern Development Trends Analysis of scientific publications and practical case studies allows identifying several key trends that define the development of monitoring systems. These directions demonstrate the evolution of tools—from basic monitoring of individual components to comprehensive analysis of distributed system behavior and their close integration with modern operational practices. Among these trends, the following can be noted: From Monitoring to Observability [13] Classic monitoring answers the question: “Is the system working?” Observability, on the other hand, allows understanding why the system is working or not, using metrics, logs, and traces. This is particularly important for distributed applications, where it is difficult to track internal processes and understand the behavior of distributed systems. Observability enables faster detection of previously unknown failures and lays the foundation for a transition from reactive monitoring to proactive infrastructure management.  Integration of Artificial Intelligence and Machine Learning (AIOps). The increasing complexity of infrastructure and the growth of telemetry data volumes make manual analysis inefficient. As a result, AIOps platforms are becoming widespread, using machine SCIENCE AND INNOVATION INTERNATIONAL SCIENTIFIC JOURNAL VOLUME 4 ISSUE 12 DECEMBER 2025 ISSN: 2181-3337 | SCIENTISTS.UZ 101 learning methods to automate key processes. These processes include anomaly detection, predictive alerting, and event correlation [14].  Monitoring of Serverless and Containerized Environments. With the adoption of Kubernetes and serverless architectures (e.g., AWS Lambda, Azure Functions), the focus shifts from virtual machines to short-lived and dynamic workloads. This requires collecting metrics at the pod and namespace level, analyzing orchestration data, and using technologies such as eBPF for low-level profiling [15][16]. Conclusion The conducted study allows us to conclude that the field of IT infrastructure monitoring is undergoing a fundamental transformation, driven by the increasing complexity of technological landscapes. Monitoring systems are evolving from reactive tools for failure mitigation into proactive, intelligent platforms that play a key role in ensuring the resilience, reliability, and efficiency of business services. The classification presented in this study clearly reflects the diversity of modern solutions and demonstrates how monitoring tools flexibly adapt to various scenarios—from traditional data centers to dynamic cloud and containerized environments. Furthermore, analysis of current trends highlights a strong focus on the integration of artificial intelligence and machine learning methods (AIOps). These technologies open new opportunities for incident prediction, intelligent event correlation, and reduction of operational load on engineering teams. Thus, monitoring is evolving from an auxiliary tool into a strategic element of intelligent IT infrastructure management. REFERENCES 1. Trihinas, D., Tryfonos, A., Dikaiakos, M. D., & Pallis, G.
