SolarWinds NPM vs Prometheus
The 11pm-after-the-renewal-quote question. These aren't the same kind of thing — SolarWinds is an all-in-one platform you buy; Prometheus is a free metrics engine you assemble — so the real choice is about who carries the operational weight, not a feature checklist.
| SolarWinds NPM SolarWinds | Prometheus open source / community (CNCF) | |

| Pricing | Per deviceQuote-only No free tier | Free / OSS Free tier ✓ |
| Cost | High Element-based (largest of node/interface/volume), plus recurring annual maintenance/support; newer tiers are subscription. | Free Free software; cost is engineering time + the surrounding stack. |
| Self-host effort | Heavy | Heavy |
| Maturity | Incumbent | Incumbent |
| Protocols | SNMPWMINetFlow / sFlow / IPFIXSyslogICMP / ping | PrometheusSNMP |
| The catch | Element-based licensing is confusing and pricey, the Orion stack is heavy to run and upgrade, and post-acquisition repricing has customers nervously eyeing renewals. | Single-node by design — no native HA or long-term storage — so any serious deployment becomes a 4-5 component stack (Alertmanager, Grafana, Thanos/Mimir, exporters) you assemble and operate yourself. |
Which should you pick?
Pick SolarWinds NPM if…
You want one vendor to call, GUI-driven everything, and broad SNMP coverage out of the box — and you can stomach where the renewals are heading.
Full SolarWinds NPM profile →Pick Prometheus if…
You're cloud-native or Kubernetes-first, happy to assemble Grafana + Alertmanager + exporters, and want zero license cost and full programmability. For mostly-SNMP networks, look at Zabbix before Prometheus.

FAQ
Can Prometheus actually replace SolarWinds NPM?
For cloud-native and server metrics, yes — but not like-for-like. Prometheus is a metrics engine, not a network management system, so to match SolarWinds NPM you assemble a stack (Prometheus + Grafana + Alertmanager + snmp_exporter) and accept that classic SNMP network monitoring is its weakest area. For a mostly-SNMP estate, Zabbix is the closer replacement.
Is Prometheus cheaper than SolarWinds?
In licensing, yes — Prometheus is free. The cost moves to engineering: you run and scale the stack yourself, and add long-term storage (Thanos, Mimir, VictoriaMetrics) once local retention is not enough. Teams leaving SolarWinds over renewal cost usually still come out ahead, but they budget the person, not just the servers.
