The processor is configured to execute a reception process of receiving a signal supplied when a problem is detected in any of a plurality of logical networks in a network virtualization environment, and a first determination process of determining not to perform auto-healing in a case in which a problem is detected in a first logical network that is configured for platform monitoring and a problem is not detected in a second logical network that is configured for application monitoring. ## Claims ### Claim 1 A network management apparatus comprising: at least one processor configured to execute a reception process of receiving a signal supplied when a problem is detected in any of a plurality of logical networks in a network virtualization environment, and a first determination process of determining not to perform auto-healing in a case in which a problem is detected in a first logical network that is configured for platform monitoring and a problem is not detected in a second logical network that is configured for application monitoring. ### Claim 2 (depends on 1) The network management apparatus according to claim 1, wherein the processor is configured to further execute a first confirmation process in a case in which a problem is detected in the second logical network, the processor repurposing a third logical network that is configured for application control in auto-healing in the virtualization environment to an interim task for an application monitoring and the processor confirming whether or not a problem is detected in application monitoring by the third logical network in the first confirmation process, the third logical network involving components that are the same as components in the second logical network, and a second determination process of determining to perform auto-healing in a case in which a problem is detected in application monitoring by the third logical network in the first confirmation process. ### Claim 3 (depends on 2) The network management apparatus according to claim 2, wherein the first confirmation process includes requesting a response from a component involved in the third logical network corresponding to the problem detected in the second logical network, and confirming whether or not there is the response from the component. ### Claim 4 (depends on 2) The network management apparatus according to claim 2, wherein the first confirmation process includes confirming whether or not a component involved in the third logical network corresponding to the problem detected in the second logical network detects a problem. ### Claim 5 (depends on 1) The network management apparatus according to claim 1, wherein the processor is configured to further execute a second confirmation process in a case in which a problem is detected in the second logical network, the processor using a fourth logical network that is configured for a mobile service in the virtualization environment and the processor confirming whether or not a problem is detected in the fourth logical network in the second confirmation process, and a third determination process of determining not to perform auto-healing in a case in which a problem is not detected in the fourth logical network in the second confirmation process, and determining to perform auto-healing in a case in which a problem is detected in the fourth logical network in the second confirmation process. ### Claim 6 (depends on 5) The network management apparatus according to claim 5, wherein the second confirmation process includes acquiring an operating status of a VNF or a CNF that communicates with a VNF or a CNF corresponding to the problem detected in the second logical network via the fourth logical network. ### Claim 7 A network management method comprising: receiving a signal supplied when a problem is detected in any of a plurality of logical networks in a network virtualization environment; and determining not to perform auto-healing based on a problem being detected in a first logical network that is configured for platform monitoring and a problem not being detected in a second logical network that is configured for application monitoring.
