| Overview | Zabbix monitors servers, network devices, applications and cloud services using agents, SNMP, and other collection methods, with built-in alerting, templates, and high-availability clustering. | Datadog collects infrastructure metrics, logs, traces, and other signals so teams can investigate services and configure alerts. | Prometheus scrapes time-series metrics from instrumented targets, stores them locally, and evaluates alerting rules with PromQL, forwarding alerts to Alertmanager. It has no built-in dashboarding or long-term storage layer of its own. |
