Work out sensor polling bandwidth instantly with clear inputs, formula shown and shareable results.
Polling bandwidth is sensors divided by interval, multiplied by the round-trip byte count. The interval is the dominant lever: halving it doubles both bandwidth and the request rate the collector must sustain. Push or event-driven reporting eliminates the request half entirely and only sends data when something changes.
Polling load
polls per second = sensors / interval; bytes per second = polls x (request + response); Mbps = bytes x 8 / 1e6
Push scales far better because it removes the request traffic and only reports changes. Polling is simpler and gives a known worst-case load, which is why it persists.
Requests per second and the per-poll processing cost. Thousands of polls per second usually exhaust the collector's connection handling long before bandwidth becomes an issue.
