Best Self Hosted Alternatives to Zabbix Cloud

Prometheus is an open-source systems and service monitoring platform built around a time-series database. It collects metrics from instrumented targets, lets you query them with PromQL, and supports alerting based on rules.

Key Features

• Multi-dimensional time series data model using labels for flexible filtering and aggregation
• PromQL query language for ad-hoc analysis, dashboards, and alert conditions
• Pull-based metric scraping over HTTP with support for static configs and service discovery
• Alert rule evaluation with alert generation (commonly paired with Alertmanager)
• Federation support for hierarchical and cross-environment aggregation
• Remote write/read integrations for long-term storage and interoperability

Use Cases

• Monitoring Kubernetes clusters and cloud-native services via dynamic service discovery
• Application and infrastructure telemetry for SRE/DevOps dashboards and alerting
• Central metrics collection for microservices, batch jobs (via push gateway patterns), and exporters

Limitations and Considerations

• Built-in storage is optimized for a single-node TSDB; long-term retention and global scale typically require external remote storage integrations

Prometheus is a strong fit when you want a reliable, standards-based metrics platform with powerful querying and a broad ecosystem of exporters and integrations. It is widely used for cloud-native monitoring and alert-driven operations.

Zabbix is an enterprise-class, open-source distributed monitoring and observability solution for tracking performance and availability across IT and OT environments. It collects metrics from agents and agentless sources and provides centralized visibility, alerting, and reporting.

Key Features

• Agent-based and agentless metric collection for servers, network devices, services, and applications
• Automatic discovery and template-based monitoring for rapid onboarding
• Real-time problem detection, correlation, and root-cause analysis workflows
• Flexible alerting and notifications with multiple delivery channels and integrations
• Dashboards and visualizations including graphs, maps, and topology views
• Distributed monitoring for remote sites and large environments, including multi-tenant use
• Built-in reporting, auditing, SLA calculations, and HTTP-based data streaming

Use Cases

• Infrastructure monitoring for networks, servers, virtual machines, and container platforms
• Application and service monitoring with proactive alerting and SLA tracking
• Centralized observability for multi-site or managed service provider environments

Zabbix is a mature, scalable platform suited for organizations that need deep visibility across diverse systems with strong alerting and flexible data collection options. It can serve as a unified monitoring backbone for both small deployments and large, distributed environments.

Nutify is a web-based monitoring system for Uninterruptible Power Supply (UPS) devices built around Network UPS Tools (NUT). It collects UPS metrics, visualizes real-time and historical data, and helps you track battery health, power events, and overall device status from a centralized dashboard.

Key Features

• Real-time UPS monitoring with interactive data visualization
• Historical data persistence and reporting (including scheduled/automated reports)
• Multi-user authentication with granular permissions for pages and configuration
• Web-based setup wizard for configuring UPS connection and NUT settings
• Flexible deployment modes: run as a NUT server or connect as a lightweight client to a remote NUT server
• Alerting and notifications via email, ntfy, webhooks, and Discord
• Event logging, UPS command execution (with permission control), and connection recovery
• Docker and Docker Compose deployment with multi-architecture images

Use Cases

• Monitor a homelab or small office UPS and receive alerts on power and battery events
• Centralize visibility for multiple systems by connecting to an existing NUT server
• Generate periodic reports on UPS performance and energy/battery behavior for planning and maintenance

Limitations and Considerations

• Compatibility depends on NUT driver support and correct USB/network access from the host/container
• Some deployments may require elevated container privileges and device passthrough for USB-connected UPS devices

Nutify is well-suited for operators who want a modern UI on top of NUT, combining real-time dashboards, historical reporting, and configurable alerting. Its setup wizard and Docker-based deployment make it approachable while still supporting advanced configurations and multi-user access control.
