Distributed computing system that monitors client device request time in order to detect performance problems and automatically issue alerts

摘要

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.

1. A client device that sends a request to a server via a network in a distributed computing system, the client device comprising:
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 the network from the server in response to the request sent by the client device; a network interface coupled to the network for sending the request to the server and receiving the results from the server; and a processor coupled to the timer and the network interface; wherein, after receiving the results from the server, the processor is configured to compare the request time duration with a request 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 request time duration is greater than the request time threshold; and the processor is further configured to dynamically calculate the request time threshold according to historic request time durations timed by the timer for a plurality of previous requests sent by the client device; wherein the previous requests sent by the client device are of a plurality of types; and the processor is further configured to dynamically calculate the request time threshold according to historic request time durations of only previous requests of a same type as the request.
