A method, system and program product for verifying configuration of a computer system is disclosed. The method includes generating, using a configuration snapshot tool, first and second configuration snapshots of relevant components of a computer system taken at a first and a second point-in-time, respectively, and comparing data in the first configuration snapshot to data in the second configuration snapshot to identify any critical and significant configuration changes while excluding identifying any insignificant configuration changes that do not significantly effect an acceptable level of operation and an intended purpose of the computer system. The method includes alerting as to any critical configuration changes identified, while informing as to any significant configuration changes identified for the computer system. The method further includes defining in a configuration file all the relevant components whose configuration is to be verified, such that relevant components can be added and non-relevant components can be deleted.
