8. Better Stack

Why Look for Zenoss Alternatives?

1. No Native OpenTelemetry (OTEL) Support

Zenoss was built around legacy protocols like SNMP and WMI. It does not offer native support for OpenTelemetry, the emerging standard for vendor-neutral instrumentation. Modern DevOps teams using OTEL for traces, logs, and metrics would need complex workarounds or third-party collectors.

2. Limited MELT Coverage

While Zenoss performs well in infrastructure metrics and event correlation, it lacks first-party capabilities for:

• APM (application performance monitoring)
• RUM (real user monitoring)
• Synthetics
• Error tracking
  This makes it unsuitable for teams that want unified visibility across frontend, backend, and infra.

3. No Smart Sampling Strategy

Zenoss does not support tail-based or head-based sampling, as it lacks any real distributed tracing functionality. This limits its usefulness in high-volume microservice environments where trace filtering is essential.

4. Opaque Pricing and Expensive Licensing

Zenoss’ commercial offerings (like Zenoss Cloud) do not offer transparent pricing. Costs vary depending on the number of nodes and features, with many users reporting expensive contracts and enterprise-level lock-in. There’s also no free tier or usage-based flexibility for scaling teams.

5. High Resource Footprint and Complex Setup

Zenoss has been criticized for being resource-intensive, particularly in terms of CPU and memory usage, which impacts performance in larger environments. Users have noted that Zenoss struggles to scale effectively, with slow performance when monitoring thousands of nodes or devices. In some cases, adding more collectors did little to alleviate performance bottlenecks, and the system was described as “buggy” when handling large-scale deployments

Even in its free (now-deprecated) form, Zenoss required resource-heavy deployment and steep configuration effort. Self-hosted setups often ran into issues with unstable probes, disconnected services, and complex Zope-based architecture.

6. Opaque Architecture and Steep Learning Curve

Zenoss is often described as complex and difficult to learn, especially for new users or those without prior experience. The system’s architecture, including its use of Zope and other components, can be opaque, making setup and maintenance challenging. Users have noted that managing Zenoss, particularly in larger deployments, can require significant effort or even a full-time employee, which may deter organizations with limited resources.

As one user notes:

“The interface was a balance between complex and simple if you just took some time to learn it and earn it. Last time I tried to load the open source version of Zenoss there was some kind of terrible simplification front end that just made it terrible.”(G2 Review)

Criteria for Suggesting Zenoss Alternatives

When evaluating replacements for Zenoss, we considered modern observability requirements that go beyond just infrastructure monitoring. The tools featured in this list were selected based on the following criteria:

1. Native OpenTelemetry (OTEL) Support

OpenTelemetry is now the industry standard for collecting traces, metrics, and logs in a vendor-neutral way. A strong Zenoss alternative must support OTEL natively — not via plugins or workarounds — to ensure seamless instrumentation, future compatibility, and flexibility in cloud-native environments.

2. Full MELT Stack Coverage

Modern teams need end-to-end visibility across Metrics, Events, Logs, and Traces (MELT). We prioritized tools that offer full-stack observability, including APM, infrastructure metrics, real user monitoring (RUM), synthetics, and log analysis — areas where Zenoss falls short.

3. Smart Sampling Strategies

High-throughput environments generate millions of spans and logs. Effective sampling (especially tail-based sampling) is critical to retain meaningful data without blowing up storage costs. Unlike Zenoss, which lacks trace-level sampling, top alternatives in this list offer intelligent ways to manage telemetry volume.

4. Flexible Deployment Options

While Zenoss supports self-hosting, its setup is resource-intensive and outdated. We focused on tools that offer modern deployment flexibility — from lightweight self-hosted options to scalable SaaS — with simpler setup and lower maintenance overhead.

5. Transparent Pricing & Cost Efficiency

Zenoss does not offer public pricing, and users often report high enterprise licensing costs. This list emphasizes tools with clear, usage-based pricing models, lower TCO, and better cost control — especially at scale.

6. Reliable Support & Documentation

Post-sales support matters. We evaluated how quickly vendors respond, whether they offer Slack or ticket-based support, and how comprehensive and current their documentation is. Zenoss, especially for non-enterprise users, has been flagged for limited support responsiveness and a reliance on outdated community forums.

G2 Rating: 4.6/5
Users love Better Stack’s interface, setup speed, and pricing clarity, but often mention its limited telemetry depth and lack of backend observability as trade-offs.

Better Stack vs Zenoss

Zenoss focuses on traditional infrastructure monitoring, using SNMP and legacy protocols, but lacks modern observability coverage like logs, traces, or RUM. Better Stack, on the other hand, delivers a modern, UX-driven experience for log collection, uptime tracking, and incident alerting, but doesn’t support backend observability or tracing either. While both tools have limitations, Better Stack is far easier to deploy, better suited to modern DevOps workflows, and offers real-time alerting with status pages—features Zenoss lacks. For small teams needing fast, visual uptime and logging tools, Better Stack is a more agile alternative to the heavyweight, infrastructure-first model of Zenoss.

Conclusion: Choosing the Right Zenoss Alternative

As modern observability needs evolve, traditional infrastructure-first tools like Zenoss are falling short. While it served its purpose in SNMP-heavy, on-prem environments, Zenoss struggles to meet today’s expectations around OpenTelemetry adoption, full MELT stack support, cost transparency, and cloud-native flexibility. From lack of tracing and RUM to opaque pricing and resource-heavy setup, many teams are actively replacing Zenoss with more modern, scalable solutions.
