### 3. How “most popular” is being inferred

Since there is no single global popularity ranking, the tools above are identified as “most popular” by:

- **Frequency of appearance** in 2026 “best network monitoring tools” or “most widely deployed” lists.[1][2][3][4][7]

- **Statements about adoption**, such as PRTG being used by over 150,000 admins or SolarWinds NPM being widely deployed in mid‑to‑large enterprises.[1][7]

- **Coverage across different segments**, e.g., enterprise vs SMB, on‑prem vs cloud, commercial vs open‑source.

If you tell me your environment (size, on‑prem vs cloud, need for open‑source vs commercial, budget), I can narrow this down to a short, targeted recommendation list rather than the full landscape.
