Managed endpoint log rate: 10 events/s per device

A managed endpoint source typically produces 10 events per second per device, bursting to 100: detections only is far lower, full telemetry far higher. The rate is an informed estimate, a starting point for a sizing, not a measurement; the event sizes below are measured.

Measure a sample of your own

The figure above is an average; yours will differ, and for managed endpoint logs what moves it most is this: detections only is far lower, full telemetry far higher. The profiler reads a sample from managed endpoint logs in your browser, line by line, one event per line, and reports the bytes per line to set against it. Nothing is uploaded.

Logcaliper, free on iOS, has these sizes and rates built in and sizes a whole list of sources at retention: storage, cluster capacity, nodes.
