DATACENTER HEALTH ANALYSIS USING DNS SWITCHING

摘要

Technologies are generally described for monitoring application health in datacenters through load rebalancing. In some examples, a domain name server (DNS) module may cyclically vary load provided to an application instance. A monitoring module may then measure application output data and/or parameters associated with the processing of the load by the application based on a difference or a comparison between parts of the cyclical load variation. The monitoring module may use the measured data/parameters to both determine the health of the application instance and to cause the DNS module to adjust the periodic variation of the load.

1. A method for monitoring application health in a datacenter, the method comprising:
providing a cyclically varying load to an application instance to be processed by the application instance; monitoring application output data associated with the processing of the cyclically varying load by the application instance; determining a data parameter associated with the monitored application output data based on one of a difference or a comparison between parts of the cyclical load variation; and determining a health of the application instance based on the determined data parameter and the monitored application output data.
