Abstract: A client device sends a request to a server via a network and times a request time duration while waiting for results to be received. The client further times an operation time duration substantially corresponding to a period of time that the client device is performing an operation that causes the client device to make the request. After receiving the results from the server, a processor of the client is operable to dynamically calculate a client processing time threshold at least according to a type of the operation and historic time durations for one or more previous operations performed by the client device. The processor further subtracts the request time duration from the operation time duration to thereby calculate a client processing time duration, and transmits one or more alert messages to a network operation center when the client processing time duration is greater than the client processing time threshold.

Abstract: A client device in a distributed system sends a request to a server via a network and receives a service time duration from the server. The service time duration corresponds to time that the server spent servicing the request. A processor of the client device compares the service time duration with a dynamically generated service time threshold, and automatically issues one or more alert messages to a network operation center (NOC) when the service time duration is greater than the service time threshold. The service time threshold is dynamically calculated according to historic service time durations received from the server for a plurality of previous requests sent by the client device. The service time threshold is dynamically calculated according to historic service time durations of only previous requests of a same type as the request, where the previous requests sent by the client device are of a plurality of types.

Abstract: A client device in a distributed system includes a timer for timing a request time duration substantially including a period of time that the client device is waiting for results to be received via a network from a server in response to a request sent by the client device. A processor of the client device compares the request time duration with a dynamically generated request time threshold, and automatically controls a network interface to issue one or more alert messages to a network operation center (NOC) via the network when the request time duration is greater than the request time threshold. The request time threshold is dynamically calculated according to historic request time durations timed by the timer for a plurality of previous requests sent by the client device.

Abstract: A client device in a distributed system may include a timer for timing a request time duration substantially including a period of time that the client device is waiting for results to be received via a network from a server in response to a request sent by the client device. A network interface may receive a value of a service time duration from the server. The service time duration may correspond to time that the server spent servicing the request. A processor may subtract the service time duration from the request time duration to thereby calculate a difference time duration, and automatically control the network interface to issue one or more alert messages to a network operation center (NOC) via the network when the difference time duration is greater than a difference time threshold. The difference time threshold may be determined according to a type of the request.
