1. A system comprising:

  • a message queue to receive wrapped packets from tapping points, the wrapped packets each comprising a packet and a wrapper header, the wrapper header comprising;

    a capture timestamp;

    a tapping point identifier;

    a packet address and a packet port;

    a message content hash; and

    if present in the packet, an inner address, and an inner port; and

    a non-transitory computer readable medium including instructions executable by a processor to, for each of a set of wrapped packets received from a set of tapping points;

    calculate a correlation key using wrapper header data;

    match wrapped packets having matching correlation keys;

    calculate a message latency through the set of set of tapping points using the capture timestamps of the matched wrapped packets, wherein the correlation key is calculated for a first wrapped packet received from a first tapping point using different wrapper header data elements than for a second wrapped packet received from a second tapping point.
