An improved technique involves a device monitoring system providing alerting rules for a particular computing environment automatically based on existing alerting rules sets for other computing environments. Along these lines, when an IT professional monitors a computing environment through the device monitoring system, the device monitoring system stores alerting rules sets for that computing environment in a database. In storing rules sets and other information about that and other computing environments, the device monitoring system acquires intelligence from a wealth of data concerning how other IT professionals react to configuration changes in their computing environments. In this way, the device monitoring system then suggests alerting rules for a particular computing environment whose alerting rules are found to be suboptimal based on performance data from the particular computing environment.
