The short answer
Datadog is the pick for broad, full-stack cloud observability across many services. Choose Rivana if you need dedicated storage-fleet monitoring that stays entirely on your own infrastructure — per-device eBPF latency and SMART degradation alerts — without sending telemetry to the cloud or paying a per-host SaaS subscription that climbs with fleet size.
Side by side
| Detail | Rivana | Datadog |
|---|---|---|
| Focus | Purpose-built storage-fleet monitoring | Cloud SaaS observability platform |
| Per-device I/O latency | Per-device I/O latency distributions via eBPF (not just averages) | Disk I/O metrics via the Datadog Agent |
| Drive-failure prediction | SMART degradation trends that flag drives before they fail | Disk integration + custom monitors (no SMART model) |
| Deployment | Self-hosted single binary — deploys in ~10 min, no cloud | SaaS — the agent ships telemetry to Datadog's cloud |
| Pricing | Per-device annual license (free 30-day trial) | Per-host/per-feature subscription (scales up fast) |
| Best for | Infra teams running 50–500 on-prem SSD/HDD drives, tired of guessing why latency degraded | Full-stack cloud observability across many services |
Strengths & trade-offs
Rivana
Infra teams running 50–500 on-prem SSD/HDD drives, tired of guessing why latency degraded
Rivana is a self-hosted monitoring tool built specifically for storage fleets. A lightweight eBPF collector on each host captures real per-device I/O latency — full distributions, not just averages — alongside SMART attributes, temperature, and utilization, and the aggregator flags drives whose degradation trends predict failure. It installs as a single Rust binary in about ten minutes, runs entirely on your own infrastructure with no cloud dependency, and is licensed per monitored device.
Strengths
- Built only for storage — per-device latency, SMART, and degradation in one place
- eBPF captures real I/O latency distributions, not just averages
- Flags failing or slow drives from SMART trends before they cause an outage
- Self-hosted single binary — deploys in ~10 minutes, no cloud dependency
- Fleet-wide view of 50–500+ drives out of the box
Consider
- Storage-focused — not a general-purpose metrics platform
- Commercial per-device license (free 30-day trial, then paid)
- Linux hosts (the collector uses eBPF)
- Newer than the established monitoring stacks
Datadog
Full-stack cloud observability across many services
Datadog is a best-in-class SaaS observability platform covering infrastructure, APM, logs, and more, with disk and system metrics through its agent. It's powerful and broad, but it's cloud-based — your telemetry leaves your infrastructure — priced as a per-host subscription that climbs quickly at fleet size, and storage is a small slice of a much larger platform rather than a dedicated drive-health tool.
Strengths
- Comprehensive observability: infrastructure, APM, logs, and more
- Polished UI, integrations, and alerting
- Managed SaaS — nothing to host yourself
- Strong dashboards and anomaly detection
Consider
- Cloud SaaS — your telemetry leaves your infrastructure
- Per-host subscription gets expensive at fleet scale
- No SMART degradation / drive-failure-prediction model
- Storage is a small part of a broad platform
Frequently asked questions
Is Rivana a replacement for Datadog?
Datadog is the pick for broad, full-stack cloud observability across many services. Choose Rivana if you need dedicated storage-fleet monitoring that stays entirely on your own infrastructure — per-device eBPF latency and SMART degradation alerts — without sending telemetry to the cloud or paying a per-host SaaS subscription that climbs with fleet size.
What storage devices and metrics does Rivana monitor?
Rivana monitors NVMe SSDs, SATA SSDs, and HDDs on Linux hosts. A lightweight eBPF collector captures per-device I/O latency distributions, SMART attributes, temperature, and utilization, and the aggregator surfaces fleet-wide dashboards plus degradation trends that flag drives likely to fail.
Does Rivana run on my own infrastructure?
Yes. Rivana is self-hosted: the aggregator installs as a single Rust binary in about ten minutes with an embedded database, and licenses are validated locally with no phone-home or internet dependency. Your storage telemetry never leaves your infrastructure.
