You need to monitor your IT infrastructure. How do you find the best network monitoring tools?

Defining network monitoring objectives entails understanding IT infrastructure, business requirements, and challenges. It involves analyzing business needs, assessing infrastructure, selecting KPIs related to performance and health, choosing appropriate monitoring tools for a unified network view, and establishing incident response plans to minimize business disruptions. Objectives focus on ensuring operational continuity, visibility, performance optimization, and effective incident management, crucial for maintaining robust network operations.

Network monitoring is key for IT infrastructure performance, availability, and security. It involves understanding various tools that align with business practices and goals. Tools include Network Performance Monitoring (NPM) for identifying performance issues, Flow-based Monitoring for analyzing traffic patterns, Network Device Health Monitoring for checking device status, and Network Security Monitoring (NMS) for detecting threats. Best practices include integration, proactive analysis, and scalability. The choice of tool depends on business objectives, network complexity, and resources.

Evaluating network monitoring tools involves assessing scalability, compatibility, customization, usability, and cost. Criteria include managing network growth, supporting diverse systems, enabling tailored setups, ensuring user-friendliness, and budget alignment. Key considerations are distributed monitoring, protocol/platform support, custom alerts/dashboards, intuitive interfaces, and flexible pricing. This framework guides the selection of tools that meet current and future needs.

While it's true that choosing a network monitoring tool depends on the specific needs of each organization, there are still some features and capabilities that are always valuable. The following are the main features that we evaluated: - security requirements, the expected traffic, the size of the network, etc. - error management, the event log, the reporting of anomalies, the performance monitor, etc. to be essential - at least protocols such as SNMP, NetFlow and sFlow were available; Among the products evaluated were Nagios, Wireshark, Cisco Prime, Dynatrace, to name just a few. Obviously when choosing a product it is necessary to consider the costs associated with it. The available demos and the possibility to test it are also important.

Exemple: A company aims to ensure high availability and optimize performance across its hybrid infrastructure, including on-premises data centers, cloud resources, and containers. It adopts Prometheus for real-time metrics collection and analysis, and Grafana for visualization and alerts. Key metrics are defined for monitoring; Prometheus is configured to collect data across all sources; Grafana dashboards visualize infrastructure health, and alert rules are set for critical thresholds to enable rapid response.
