Methods, systems, and articles for receiving, by a monitor server, change data associated with a change captured on a target host, are described herein. In various embodiments, the target host may have provided the change data in response to detecting the change, and the change data may include one or more rules, settings, and/or parameters. Further, in some embodiments, the monitor server may then group the change data into clusters and may correlate the clusters with a change catalog in order to provide a possible reason or cause for the cluster of changes. Once the change data have been classified as clusters, a report may be generated providing classification or categorization and cluster information for the various changes. In various embodiments, the generating may comprise generating a report to the target host and/or to an administrative user. In various embodiments, a reason may be determined for causing a cluster of changes and the change catalog may updated with the reason.
