Abstract

A server system has a function to send management information in response to a management information transmission order from an external manager as well as relates to a server which is a component of the server system. It is capable of acquiring object management information by specifying the same object ID both when a manager acquires server management information via a management section and when the manager instructs a server directly to send management information. Not only the management section, but also the servers use SNMP proxy functions. Also, the same objects as those defined in the MIB tree of the management section are defined in the MIB tree of each server and SNMP proxy settings are made for each server in such a way as to convert the OIDs of the defined objects into desired OIDs in the MIB tree of the server itself.

Claims

1. A server system comprising at least one server and a management section which acquires management information stored in the server, wherein:

each of the at least one server comprises;

a management information acquisition section which acquires management information stored in the server itself,

communications section which can receive both management information transmission order containing a first ID and management information transmission order containing a second ID, where the first ID is an ID of a given object including a server ID of a given server among server-specific server IDs used to distinguish the at least one server from one another while the second ID is an ID of the given object including a common server ID which indicates a server without distinguishing the at least one server from one another and which is used within the management information acquisition section, the given server being the server itself and the given object being management information to be acquired from the given server, and

a first ID conversion section which converts the first ID contained in a management information transmission order received by the communications section into a second ID which represents the same given object as the given object represented by the first ID;

the management information acquisition section acquires management information, which is the given object identified by the second ID;

the communications section sends the management information acquired by the management information acquisition section to an orderer of the management information;

the management section comprises;

a first communications section which receives a management information transmission order containing a first ID from an external manager, where the first ID is an ID of a given object including a server ID of a given server out of the at least one server, the given object being management information to be acquired from the given server,

a second ID conversion section which converts the first ID contained in a management information transmission order received by the first communications section into a second ID containing the common server ID which is used within the management information acquisition section in the given server and which represents the same given object as the given object represented by the first ID, and

a second communications section which sends a management information transmission order containing the second ID obtained by the second ID conversion section to the given server and receives management information returned from the given server; and

the first communications section sends the management information received by the second communications section to the manager which is the orderer of the management information.

2. The server system according to claim 1 wherein:

the first ID conversion section comprises;

a first conversion table which associates the server ID of the server itself with the common server ID, and

a first system table which contains the server ID of the server itself and the common server ID and describes a system of the IDs of objects constituting management information which can be transmitted, the system of the IDs being linked to the common server ID and being common among all servers; and

the first ID conversion section converts the first ID into the second ID with reference to the first conversion table and the first system table.

3. The server system according to claim 1 wherein:

the second ID conversion section comprises;

a second conversion table which associates a communications address of each of the at least one server, the server ID of each of the at least one server, and the common server ID with one another, and

a second system table which contains the server ID of each of the at least one server and the common server ID and describes a system of the IDs of objects constituting management information which can be transmitted, the system of the IDs being linked to the common server ID and being common among all servers; and

the second ID conversion section converts the first ID into the second ID with reference to the second conversion table and the second system table.

4. The server system according to claim 3 wherein the management section comprises a correspondence table which associates the communications address of each of the at least one server and the server ID of each of the at least one server with each other, and a second conversion table creating section which creates the second conversion table with reference to the correspondence table.

5. The server system according to claim 4 wherein the second conversion table creating section manages the correspondence table and makes additions/updates to the second conversion table in accordance with additions/updates to the correspondence table.

6. The server system according to claim 4 wherein:

the first ID conversion section comprises;

a first conversion table which associates the server ID of the server itself with the common server ID, and

a first system table which contains the server ID of the server itself and the common server ID and describes a system of the IDs of objects constituting management information which can be transmitted, the system of the IDs being linked to the common server ID and being common among all servers;

the first ID conversion section converts the first ID into the second ID with reference to the first conversion table and the first system table; and

each of the at least one server comprises a first conversion table creating section which creates the first conversion table with reference to the correspondence table in the management section.

7. A server in a server system comprising at least one server and a management section which acquires management information stored in the server, the server comprising:

a management information acquisition section which acquires management information stored in the server itself;

communications section which can receive both management information transmission order containing a first ID and management information transmission order containing a second ID, where the first ID is an ID of a given object including a server ID of a given server among server-specific server IDs used to distinguish the at least one server from one another while the second ID is an ID of the given object including a common server ID which indicates a server without distinguishing the at least one server from one another and which is used within the management information acquisition section, the given server being the server itself and the given object being management information to be acquired from the given server; and

a first ID conversion section which converts the first ID contained in a management information transmission order received by the communications section into a second ID which represents the same given object as the given object represented by the first ID,

wherein the management information acquisition section acquires management information, which is the given object identified by the second ID, and

the communications section sends the management information acquired by the management information acquisition section to an orderer of the management information.

8. The server according to claim 7 wherein:

the first ID conversion section comprises;

a first conversion table which associates the server ID of the server itself with the common server ID, and

a first system table which contains the server ID of the server itself and the common server ID and describes a system of the IDs of objects constituting management information which can be transmitted, the system of the IDs being linked to the common server ID and being common among all servers; and

the first ID conversion section converts the first ID into the second ID with reference to the first conversion table and the first system table.

9. The server according to claim 8, comprising a first conversion table creating section which creates the first conversion table with reference to a correspondence table that exists in the management section and associates the communications address of each of the at least one server and the server ID of each of the at least one server with each other.
