OnlineMonitoring

OnlineMonitoring is the practice of collecting, transmitting, and analyzing data from devices, services, and users over networks in real time to assess performance, availability, and security. It encompasses monitoring of IT infrastructure, cloud services, applications, networks, and even external websites or APIs. The goal is to detect issues early, track trends, and support decision-making. Monitoring is typically continuous and automated, relying on probes, agents, and telemetry.

Key components include data sources such as agents on servers and devices, passive network probes, synthetic transactions, and user activity signals. Data is transported to processing pipelines, stored, and analyzed using dashboards and alerting systems. Common approaches include real-time streaming analytics, batch reporting, and anomaly detection. Observability practices expand monitoring to include traces, metrics, and logs to understand system behavior.

Typical use cases include service level monitoring for uptime and response times, capacity planning, incident response, security monitoring, and compliance reporting. Organizations use dashboards and alerts to notify operators of deviations, enabling rapid diagnosis and remediation.

Privacy, security, and governance are central concerns in online monitoring. Telemetry data may contain sensitive information, requiring access controls, encryption, and data minimization. Interoperability between tools and standards, data retention policies, and compliance with regulations are important considerations in designing a monitoring program.
