1. In a device monitoring system constructed and arranged to communicate alerts, via a set of alerting rules, in response to changes within a computing environment, a method of providing alerting rules for a particular computing environment, the method comprising: storing multiple alerting rule sets in a rule set database, the multiple alerting rule sets providing sets of alerts when applied to configuration data of existing computing environments; selecting particular alerting rules among the multiple alerting rule sets stored in the rule set database, the particular alerting rules providing particular alerts when applied to configuration data of an existing computing environment; and providing the particular alerting rules to the particular computing environment, wherein each existing computing environment is managed by an expert user, each expert user receiving alerts from the device monitoring system in response to configuration changes within the existing computing environment managed by that expert user according to an alerting rule set stored in the rule set database, wherein each alerting rule of the multiple alerting rule sets includes (i) a configuration change identifier identifying a configuration change in an existing computing environment and (ii) a respective alert indicator indicating whether an alert is to be issued in response to the configuration change identified by the configuration change identifier, wherein selecting the particular alerting rules includes: performing a comparison operation between the existing computing environments and the particular computing environment, the comparison operation producing a comparison result indicative of whether the existing computing environments are similar to the particular computing environment; and picking, as the particular alerting rules, rules from the multiple alerting rule sets based on the comparison result.
