Zenoss is designed for large enterprise IT teams managing complex infrastructure. Atatus is built for teams who need deep application visibility, real user monitoring, and fast error triage without the weight of an enterprise AIOps platform.
Zenoss is purpose-built for large enterprise IT operations teams managing thousands of infrastructure components. It correlates events, maps dependencies, and reduces noise at the infrastructure layer. But when a slow API, a crashing endpoint, or a frontend error is hurting your users, Zenoss does not go there. Atatus does.
Atatus traces every request from the browser through your APIs, services, and databases with full distributed tracing. Zenoss maps infrastructure dependencies but does not instrument application code or produce transaction-level traces.
Atatus captures Core Web Vitals, session-level data, and JS errors from real users in production. Zenoss has no real user monitoring capability — frontend performance is entirely outside its scope.
Atatus agents install with a single command and start sending traces within minutes. Zenoss is designed for large IT teams with dedicated administrators. Deployment, configuration, and onboarding are significantly heavier for smaller or developer-led teams.
Here is where Atatus delivers capabilities that Zenoss does not cover at all, specifically for development and product engineering teams.
Atatus shows you the full trace of a failed request, the SQL query that timed out, and the stack trace in one view. Zenoss operates at the infrastructure event level and has no visibility into what happened inside your application code.
When Core Web Vitals drop or a JavaScript error spikes, Atatus captures it from real browsers with session-level context. Zenoss has no real user monitoring and no frontend visibility whatsoever.
Atatus unifies structured logs alongside traces and metrics so you can pivot from a slow transaction directly to the relevant log lines. Zenoss handles infrastructure event logs but does not correlate application logs with code-level traces.
Atatus is designed for development teams to self-serve. Install the agent, add the RUM snippet, and you are collecting data. Zenoss requires significant infrastructure knowledge, configuration, and typically a dedicated ops team to deploy and manage effectively.
When a downstream service degrades, Atatus shows exactly which transactions and user sessions are impacted with frontend and backend data in one timeline. Zenoss surfaces the infrastructure event but does not connect it to user impact.
Atatus lists its plans publicly with no sales call required. Zenoss pricing is enterprise-negotiated with no public rates. For growing teams that need fast decisions, that difference in process matters significantly
A clear look at where each platform focuses and where the gaps are for application and frontend teams.
Full-stack APM — distributed tracing from browser to database across Node.js, Python, Ruby, Java, .NET, PHP, Go
Real User Monitoring — Core Web Vitals, session-level detail, and JS error correlation from real user browsers
Error tracking — auto-grouped server and browser errors with stack traces and release-level attribution
Log management — structured logs unified with traces and metrics in one platform
Synthetic monitoring — HTTP and browser checks from 20+ global locations at per-minute intervals
Infrastructure monitoring — host, container, and Kubernetes metrics alongside APM data
Transparent public pricing — plans listed on the website, no sales call required
Fast self-serve onboarding — single agent install, no dedicated IT administrator needed
No application APM — Zenoss does not instrument application code or produce distributed traces
No real user monitoring — frontend performance and user session data are entirely outside Zenoss scope
No application error tracking — Zenoss handles infrastructure events, not code-level exceptions or stack traces
Infrastructure event logs — syslog and event log ingestion available; no correlation with application-level trace data
No synthetic monitoring — uptime and API checks are not part of the Zenoss core product
Infrastructure monitoring — deep server, network, storage, and data center hardware monitoring at enterprise scale
No public pricing — enterprise-negotiated only; requires a sales engagement and scoping process
Enterprise deployment model — designed for large IT ops teams; setup requires dedicated administrators and planning
“Zenoss was our infrastructure monitoring layer and it did that job well. But every time there was a user-facing issue, we had no visibility into what was happening inside the application itself. Atatus filled that gap immediately. Within a day we had traces, RUM data, and error tracking all running together.”
What teams evaluating Zenoss and Atatus together most commonly want to know.
They solve different problems. Zenoss is built for large enterprise IT operations teams managing thousands of infrastructure devices, networks, and data center hardware. Atatus is built for application observability including APM, RUM, error tracking, and logs. If your primary need is deep infrastructure and network monitoring at enterprise scale, Zenoss serves that well. If your team needs visibility inside your application and user experience, Atatus is the right fit. Many teams run both for different layers.
Atatus covers host metrics, containers, and Kubernetes alongside application data. For basic server and cloud infrastructure monitoring, Atatus handles it well. Zenoss goes significantly deeper on network device monitoring, data center hardware, SNMP, and large-scale IT event correlation, capabilities that Atatus does not replicate and is not designed to.
Zenoss uses AIOps to correlate thousands of infrastructure events and reduce noise at the IT operations layer. Atatus uses anomaly detection and automated error grouping to reduce noise at the application and user experience layer. The two approaches serve different audiences. Zenoss AIOps is designed for IT ops managing complex infrastructure; Atatus anomaly detection is designed for developers and SREs managing application performance.
Atatus agents install with a single command and most teams are collecting trace data within minutes. The RUM snippet is one script tag. Zenoss is an enterprise platform that typically requires a dedicated deployment process, infrastructure team involvement, and professional services for larger rollouts. For developer teams, the onboarding difference is significant.
Yes. Atatus supports OpenTelemetry ingestion, so if your services are already instrumented with OTel SDKs you can send traces directly to Atatus without re-instrumenting your code. This makes migration straightforward for teams that have invested in OTel-based instrumentation.
Yes. Atatus holds SOC 2 Type II certification and is GDPR compliant. Data residency options are available on Enterprise plans. Full security documentation including penetration test results and compliance reports is available on request for your security and procurement review process.
