Zabbix

Zabbix watches the availability and performance of an entire IT estate from one place, from a single standalone application up to a large environment spread across data centers. It replaces the pile of per-device checks and ad hoc scripts that accumulate around infrastructure over time.

Metrics arrive with or without an agent, from devices, sensors, operating systems, virtualization and container platforms such as Docker and Kubernetes, cloud infrastructures, databases, web pages, Java ecosystems, API endpoints and business applications. Ready-made templates cover integrations from a low-level device up to a SaaS service.

The rest of the platform turns those metrics into action.

• Resource discovery: find network entities and server resources, then onboard or offboard devices.
• Root cause analysis: detect problems in real time and correlate existing ones with incoming ones.
• Alerts and notifications: reach people through Slack, Jira, Microsoft Teams, email or text messages.
• Visualization: read collected data in graphs, lists, geomaps and network topology maps.
• Multitenancy: run one instance for several data centers, departments or organizations.

Remote locations behind firewalls are covered with remote command execution, and built-in functions handle reporting, auditing, security and service SLA calculations, with metrics and events streamed over HTTP. Zabbix is distributed under AGPL-3.0-only, with downloads and an installation manual published for self-hosted deployment.
