 Flow logs are collected at an interval of every 1 minute. All packets collected for a given flow get aggregated and imported into a Log Analytics workspace for further analysis. During flow collection, not every packet is captured into its own flow record. ExpressRoute Traffic Collector uses a sampling rate of 1:4096, meaning 1 out of every 4096 packets gets captured. Therefore, sampling rate short flows (in total bytes) might not get collected. This sampling size doesn't affect network traffic analysis when sampled data is aggregated over a longer period of time. Flow collection time and sampling rate are fixed and can't be changed.
