Prometheus is the open-source standard for cloud-native metrics, but it is metrics-only and stops at an alert. If you want correlated observability across signals with autonomous resolution, here is an honest comparison with Opstral.
Why teams evaluate an alternative to Prometheus
Prometheus is excellent at what it does: reliable metrics collection, PromQL, and alerting, and it is the backbone of cloud-native monitoring. Teams look for an alternative, or a layer on top, for three reasons. It is metrics-only, so correlating a metric spike with the trace or log behind it means bolting on other tools. Scaling it for high availability and long retention needs add-ons like Thanos, Cortex or Mimir. And, like all monitoring, it alerts a human; it does not resolve. When the goal is correlated signals and fewer incidents reaching an engineer, the evaluation moves beyond metrics and alerts.
There is also a scope question that PromQL power can obscure. Prometheus answers metrics questions extremely well, but many real incidents are not metrics questions, they are questions about a specific request, a specific log line, or the interaction between services, which metrics alone cannot answer. Teams that live entirely in Prometheus often find themselves exporting into other tools the moment an investigation needs a trace or a log, which is exactly the fragmentation a correlated platform removes. The strength of Prometheus at metrics can hide how much of incident work happens outside of metrics.
| Dimension | Prometheus | Opstral |
|---|---|---|
| Primary focus | Metrics collection, PromQL and alerting | Correlated observability and autonomous, governed resolution |
| Signals | Metrics only | Metrics, logs and traces correlated in one place |
| Scale and retention | Add-ons (Thanos, Cortex, Mimir) for HA and long-term | Petabyte-scale storage built in |
| From alert to fix | Alerts a human via Alertmanager | Closes the loop: ProcBot executes the fix, Sherlock validates it |
| Breadth | Cloud-native metrics | Ten operational domains, cross-platform |
| Deployment | Self-hosted | SaaS, on-premises or fully air-gapped |
Where Opstral is different
- It resolves, not just detectsSentinel AI runs the Observe, Investigate, Act, Optimize loop and executes the fix through ProcBot, so many incidents never need a human at all.
- Every action is governedActions run as reversible, audited Action Tickets with approval gates, so autonomy is something an auditor or a change board can accept.
- Ten domains, air-gapped readyOne intelligence layer across telemetry, service, infrastructure, security, data, cost, process, DevSec Ops and the managed estate, deployable on-premises or fully air-gapped.
Frequently asked questions
Does Opstral replace Prometheus?
Not necessarily. It works with Prometheus-compatible metrics, so many teams keep Prometheus for collection and add Opstral to correlate metrics with logs and traces and resolve incidents autonomously.
Can Opstral use PromQL and existing Prometheus data?
Yes. It supports Prometheus-compatible metrics and PromQL-style queries, so existing dashboards and skills transfer while it adds correlation and resolution.
