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.
