System monitoring apparatus, system monitoring method, and computer readable recording medium

A system monitoring method comprising:

• generating 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
• estimating 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.

A non-transitory computer readable recording medium that includes a program recorded thereon, the program including instructions that cause a computer to carry out:

• generating 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
• estimating 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.
