Abstract: A mechanism for adaptively performing in-band network telemetry (INT) by a network controller is disclosed. The mechanism includes receiving one or more congestion indicators from a collector. An adjusted sampling rate is generated. The adjusted sampling rate is a specified rate of insertion of instruction headers for INT and is generated based on the congestion indicators. The adjusted sampling rate is transmitted to a head node, which is configured to perform INT via instruction header insertion into user packets.
