FIG. 9 is a flowchart showing the operation of the management information collection unit according to one embodiment of the present invention. The flowchart shown in the figure is the packet analysis unit 2 in the management information collection unit 8.
In 4, the I obtained from the local network A2
This is an example of a case where management information is extracted from P packets based on the contents of the collection conditions and operation conditions held by the collection / operation condition management unit 23, and processing such as accumulation and notification is performed.

Step 101) In the packet analysis unit 24, the IP packet acquisition unit 21
Of the SNMP management device 5 acquired from the server. Step 102) The packet analysis unit 24
Only those containing SNMP PDUs are extracted from the P packets. At this time, if it is not an SNMP packet, the process proceeds to step 107.

Step 103) Management information is extracted based on the collection conditions and operation conditions set in the collection / operation condition management table 53, and processing is performed on the extracted management information. More specifically, the management information collection unit 8 firstly performs the SNM from the IP packet
After extracting only the IP packet including the P PDU, the entry 27 set in the collection / operation condition management table 53 is set.
The collection conditions 30 to 35 are compared with the information elements in the IP packet for every .about.29. As a result, if any of the entries 27 to 29 set in the collection / operation condition management table 53 completely matches the collection conditions 30 to 35, the process proceeds to step 104; otherwise, the process proceeds to step 107.
Move to

Step 104) An IP packet containing management information in which one of the entries 27 to 29 of the collection / operation condition management table 53 matches the collection conditions 30 to 35 is
The processing for the management information is performed based on the operation condition 36 specified in the entry. Here, it is determined whether or not the notification processing is necessary. If it is necessary, the process proceeds to step 105, and if not, the process proceeds to step 106.

Step 105) I that matches the collection condition
Of the P packets, IP packets that require notification processing are:
The source of the IP packet, that is, the IP address of the device to be managed by the SNMP management device A5 is extracted from the IP header portion of the IP packet. Here, the PDU type from the managed device in the local network A2 is
In the case of GetResponse, the source IP address extracted in the above-described processing and the VBL (Variable Binding Lis
t: an information element included in the SNMP PDU, which is a set of OID and its value), is notified to the integrated management device 1 side,
If it is “TRAP”, the source IP address and VB
L, enterprise, agent-addr, generic-tra
p, specific-trap, time-stamp "TRAP PD
The information of each field of “U” is notified to the integrated management device 1. The integrated management device 1 monitors events of the local network A2 managed by the SNMP management device A5 and changes in management information based on the notification.

Step 106) Of the IP packets that match the collection conditions and have completed processing related to notification,
It is determined whether or not the accumulation process is necessary. If necessary, the process proceeds to step 108, and if not, the process proceeds to step 107.
Move to Step 107) Discard the IP packet. Step 108) From the IP packet that matches the collection conditions and has completed the process related to the notification, the source of the IP packet, that is, the IP address of the managed device of the SNMP management device A5 Extract the address. The management information database 25 holds the management information tables 40 to 42 for each extracted transmission source IP, that is, for each managed device of the SNMP management device A5. If the management information tables 40 to 42 related to the managed device corresponding to the extracted IP address already exist, the process proceeds to step 110; otherwise, the process proceeds to step 109.

Step 109) If there is no management information table 40 to 42 for the managed device corresponding to the extracted IP address, a new management information table for the managed device is generated, and the process proceeds to step 110. . Step 110) Each entry 37- in the table
OID held in 39 and VBL in SNMP PDU
Are compared, and a pair of an index and a value is stored in the matched entry. At this time, if a combination of an index and a value already exists in the entry, the index and the value are overwritten.

If none of the combinations of indexes and values stored in the management information tables 40 to 42 and the management information table relating to the managed device are updated for a certain period of time, they are automatically deleted. By the management information accumulation process (step 110), the management information database 25 of the management information collection unit 8 can hold the latest management information of the managed device of the SNMP management device A5.

The above management information adding process (step 10)
9), the management information collecting unit 8 sets the SNMP management device A
5 can be automatically discovered. Information search processing unit 26 of management information collection unit 8
Retrieves the management information of the managed device to be managed by the SNMP management device A5 accumulated by the above operation in response to a request from the integrated management device 1, and through the integrated management device interface unit 22, 1. Provide the collected management information. Search key is managed device, OI
D, an OID, an index and a combination thereof, and the management information is an OID of the MIB, an index and a combination thereof, and the management information is M
The IB OID, index, and value are provided to the integrated management device.

It is also possible to obtain the management information of all the devices to be managed, which is stored in the management information database 25. In the integrated management device 1, the management information is acquired by the management information integrated management unit 19 and accumulated in the management information integrated database 20 in the management information collection unit 8 of the SNMP management devices 5 to 7 installed in each of the local networks 2 to 4. Performs integrated management by collecting collected information periodically.

When both notification and accumulation are specified in the process 36 described in the entries 27 to 29 of the collection / operation condition management table, both processes are performed. Further, in the above embodiment, the description has been given based on the configuration of FIGS. 5 and 6. However, the present invention is not limited to this example. 17.
