1. A network monitoring method comprising:
monitoring, at a network node, one or more object-level statistics for each of one or more objects exchanged between a client end point and a server end point through a network connection, the network node being located between the client end point and the server end point;
determining, without a measurement at the client end point and without a measurement at the server end point, one or more quality of service (QoS) metrics for each of the one or more objects, the one or more QoS metrics derived from the object-level statistics for respective one of the one or more objects, the object-level statistics including a difference between two time parameters taken at a measurement point at the network node as the one or more object is exchanged between the client end point and the server end point; and
performing a network diagnostic of a network condition of the network connection using the one or more QoS metrics, the performing of the network diagnostic including comparing one or more representative values of the one or more QoS metrics with one or more predetermined thresholds and using the comparison to determine a root cause of the network condition of the network connection.
