## Abstract

[Problem] Provided are a network system, an information acquisition apparatus, an information acquisition method, and a program capable of acquiring measurement information with fewer maintenance operations. [Solution] Provided are a disposition rule saving unit 122 that saves a disposition rule 152 indicating at least a login method and disposition corresponding to the login method of an agent, a control rule saving unit 123 that saves a control rule 153 indicating at least an OS type and control information corresponding to the OS type of a target device of a network service, a data extraction unit 111 that extracts configuration information 151 including a login method and the OS type of the target device of the network service from a response result of construction processing, an agent disposition unit 112 that determines disposition of an agent 200 based on the login method of the extracted configuration information 151 and the disposition rule 152. and an agent disposition unit 112 that determines control processing of the agent 200 based on the OS type of the extracted configuration information 151 and the control rule 153.

## Claims

### Claim 1

A network system comprising:
an agent configured to collect information of an infrastructure of a network service constructed in a network and transmit the collected information to an information acquisition apparatus via the network; and
the information acquisition apparatus configured to acquire the information from the agent,
wherein the information acquisition apparatus includes:
a disposition rule saving unit, including one or more processors, configured to save a disposition rule indicating at least a login method and disposition corresponding to the login method of the agent,
a control rule saving unit, including one or more processors, configured to save a control rule indicating at least an OS type and information of control processing corresponding to the OS type of a target device of the network service,
a data extraction unit, including one or more processors, configured to extract configuration information including a login method and the OS type of the target device of the network service from a response result of construction processing,
an agent disposition unit, including one or more processors, configured to determine disposition of the agent based on the login method of the extracted configuration information and the disposition rule saved in the disposition rule saving unit, and
an agent control unit, including one or more processors, configured to determine control processing of the agent based on the OS type of the extracted configuration information and the control rule saved in the control rule saving unit, and
the agent is dynamically disposed in the network service in accordance with the determined disposition of the agent and the determined control processing of the agent.

### Claim 2 (depends on 1)

The network system according to claim 1,
wherein the control rule saving unit further saves the control rule indicating a relationship of connection to other devices and control information corresponding to the relationship of connection,
the data extraction unit extracts the configuration information including a relationship of connection of the target device of the network service from the response result of the construction processing, and
the agent control unit determines the control processing of the agent corresponding to the relationship of connection of the target device of the extracted configuration information based on the control rule.

### Claim 3

(canceled)

### Claim 4

An information acquisition method for an information acquisition apparatus configured to acquire information from an agent that has collected information of an infrastructure of a network service constructed in a network, wherein
a disposition rule indicating at least a login method and disposition corresponding to the login method of the agent and a control rule indicating at least an OS type and information of control processing corresponding to the OS type of a target device of the network service are saved in a storage unit, and
the information acquisition method comprises:
extracting configuration information including a login method and the OS type of the target device of the network service from a response result of construction processing;
determining disposition of the agent based on the login method of the extracted configuration information and the saved disposition rule;
determining control processing of the agent based on the OS type of the extracted configuration information and the saved control rule; and
dynamically disposing the agent in the network service in accordance with the determined disposition of the agent and the determined control processing of the agent.

### Claim 5

A non-transitory computer readable medium storing one or more instructions that causes a computer serving as an information acquisition apparatus that acquires information from an agent that has collected information of an infrastructure of a network service constructed in a network to perform:
saving a disposition rule indicating at least a login method and disposition corresponding to the login method of the agent;
saving a control rule indicating at least an OS type and information of control processing corresponding to the OS type of a target device of the network service;
extracting configuration information including a login method and the OS type of the target device of the network service from a response result of construction processing;
determining disposition of the agent based on the login method of the extracted configuration information and the disposition rule saved in the saving of the disposition rule; and
determining control processing of the agent based on the OS type of the extracted configuration information and the control rule saved in the saving of the control rule.

### Claim 6 (depends on 4)

The information acquisition method according to claim 4,
the control rule indicating a relationship of connection to other devices and control information corresponding to the relationship of connection is saved in the storage unit, and
the information acquisition method further comprises:
extracting the configuration information including a relationship of connection of the target device of the network service from the response result of the construction processing; and
determining the control processing of the agent corresponding to the relationship of connection of the target device of the extracted configuration information based on the control rule.

### Claim 7 (depends on 5)

The non-transitory computer readable medium according to claim 5, wherein the one or more instructions further causes the computer to perform:
saving the control rule indicating a relationship of connection to other devices and control information corresponding to the relationship of connection;
extracting the configuration information including a relationship of connection of the target device of the network service from the response result of the construction processing; and
determining the control processing of the agent corresponding to the relationship of connection of the target device of the extracted configuration information based on the control rule.
