Claim Text:
1. A client device that sends a request to a server via a network in a distributed computing system, the client device comprising: a network interface coupled to the network and operable to send the request to the server and to receive results from the server in response to the request; the network interface further operable to receive a value of a service time duration from the server, the service time duration substantially corresponding to a period of time that the server spent servicing the request in order to provide the results; and a processor coupled to the network interface; wherein the processor is configured to compare the service time duration with a service time threshold, and to automatically control the network interface to issue one or more alert messages to a network operation center (NOC) via the network when the service time duration is greater than the service time threshold; the processor is further configured to dynamically calculate the service time threshold according to historic service time durations received from the server for a plurality of previous requests sent by the client device; the previous requests sent by the client device are of a plurality of types; and the processor is further configured to calculate the service time threshold according to historic service time durations of only previous requests of a same type as the request.
