Various embodiments herein each include at least one of systems, methods, and software for self-service terminal technical state monitoring and alerting. One such embodiment in the form of a method performed on a computer of an SST, such as an ATM or POS terminal, includes comparing at least one computer platform layer system configuration setting retrieved from a computer platform layer memory device of the SST to respective expected values stored in a second memory device of the SST. The method may then transmit an alert via a network to an alert repository including data identifying the SST when the comparing identifies at least one of the computer platform layer system configuration values does not match a respective expected value.
