Monitoring & Alerting

In the Prometheus ecosystem, Prometheus generates alerts based on alerting rules, while Alertmanager manages the entire alert lifecycle: grouping, routing, inhibition, deduplication, and notification delivery. A poorly configured Alertmanager can drown on-call engineers in a flood of duplicate alerts at 3 AM, whereas a well-designed routing and inhibition strategy ensures that “the right person receives the right alert at the right time.” Reference: Prometheus Official Documentation — Alertmanager I. Alertmanager Architecture Alertmanager’s processing pipeline consists of five stages:...

Zabbix comes from the traditional operations era, dominating physical machine/VM environments for nearly 25 years; Prometheus rose in the cloud-native era, becoming the de facto standard for the Kubernetes ecosystem. Many teams face a question when choosing a monitoring system: Zabbix or Prometheus? The answer isn’t either/or. Many mature teams run both systems simultaneously in production — Zabbix handles the infrastructure layer (network, hardware, OS), while Prometheus handles the application and cloud-native layers....
