System management device, system management method, and program

A system management device (1) includes: a data request transmission unit (5) which successively transmits data request signals (C5) to a management object system (50); a feature data extraction unit (6) which extracts feature data (D3) from data (D50) acquired by a data acquisition unit (3); an error information extraction unit (7) which extracts error information from the data; a feature data storage unit (8) which stores feature data at a time of occurrence of an error as error-occurrence-time feature data (D6) according to the error information; and a system control unit (9) which, each time the data is acquired, compares a status value included in the feature data (D3) in the acquired data with a status value included in the error-occurrence-time feature data (D6) already stored in the feature data storage unit (8) and performs control of the management object system (50) according to a result of the comparison.
