# Bandwidth used between Sensor and Brain * The bandwidth of traffic sent from a sensor to its brain is expected to be a small proportion of the traffic received by the sensor. * This proportion may vary significantly by the application profile of that traffic and cannot be precisely quantified or predicted. * However, the average traffic between the sensor to the brain is around .5% \~ 5% of the received traffic (This value varies significantly on each customer's environment). * In case you receive an alert "Sensor bandwidth too low for complete metadata replication" this means a bandwidth issue between the Sensor and the Brain . The alert is triggered when the amount of time exceeds 100 minutes. A review of the bandwidth between sensor and brain is recommended. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://docs.vectra.ai/reference/bandwidth-used-between-sensor-and-brain.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
