SYSTEM MONITORING APPARATUS, SYSTEM MONITORING METHOD, AND COMPUTER READABLE RECORDING MEDIUM

A system monitoring apparatus comprising: a complementing unit that generates complemented node information by complementing, based on a complementing model trained using information collected in a testing system using a monitoring command and an agent, first node information collected in an operated system using the monitoring command; and an estimating unit that estimates the probability of a link being present between nodes by inputting the complemented node information to a link estimating model trained using the information collected in the testing system using the monitoring command and the agent.
