Application Monitoring
Continuously tracking application health, performance, and errors in production.
Also: APM · Application Performance Management
Definition
Application monitoring involves continuously collecting, analyzing, and alerting on metrics, logs, and traces from running software systems to ensure reliability and performance. It covers infrastructure metrics (CPU, memory, disk), application metrics (request rates, error rates, latencies), and business metrics (transactions, conversions). Modern observability platforms like Datadog, New Relic, and Prometheus aggregate data from distributed systems, enabling teams to detect anomalies and respond to incidents rapidly.
Example
“The monitoring dashboard shows that API response time spiked from 150ms to 2 seconds at 3:00 AM, triggering a PagerDuty alert that woke the on-call engineer to investigate a database query regression.”
