The central collection device is a module or a plurality of modules that directly interwork with the device to perform device information collection. The central collection device divides the device list into collection threads in a batch, and the collection thread allocates the devices in the device list at a predetermined time interval. After sending ICMP and SNMP messages, the device status is identified through response messages from the device and the device information is stored in the database.

At this time, the collection thread waits for a timeout time when there is no response message from the device, and if there is still no response message after the timeout time is exceeded, the collection thread processes the collection failure.

The network management system attempts to fail after several retries upon timeout, depending on the settings of the network management operator.The time required for acquisition failure is 10 to 100 times longer than normal as timeout time × number of retries. Wait time is required.

In the case of subscriber section devices, there are many devices that are not set to SNMP inactive or SNMP collection is not normally performed due to SNMP community input error.

If a list of devices that could not be collected normally is concentrated in a particular collection thread, that collection thread may fail to poll all the devices within the collection cycle due to long latency.

In this case, the collection thread has a problem that the list of devices that cannot be collected normally is biased, and thus, the collection thread cannot be collected.

The technical problem to be achieved by the present invention is to prevent the collection of equipment that can not be collected normally to the specific collection thread, and to collect the equipment information system and method in the network management that can be adaptively polled according to the equipment status is recorded It is to provide a recording medium.

Like parts are designated by like reference numerals throughout the specification.

First, the equipment information collection system in the network management according to the first embodiment of the present invention will be described in detail with reference to FIG.

1 is a block diagram of a system for collecting equipment information in network management according to a first embodiment of the present invention.

As shown in FIG. 1, the system information collection system in the network management according to an embodiment of the present invention includes a device list database (DB) 10, a central collection unit 20, and IP devices 60.

The equipment list DB 10 is managed by the network management system, and stores equipment information of a collection target.

The central collecting device 20 manages the equipment list, and manages the information distribution module 21 and the plurality of lower collecting threads 30.

The central collection apparatus 20 divides and manages the equipment list into a collection success equipment list (PollSuccessList), a collection failure equipment list (PollFailList), and an unidentified equipment list (UnknowList) whose collection state of the previous cycle is unknown.

This is based on the determination state of the equipment information collection state of the previous cycle, assuming that the equipment that has previously failed to collect is likely to fail in the next collection cycle unless the equipment state is restored.

The information distribution module 21 divides the information of the device list DB 10 into N pieces and allocates the information to each collection thread, and collects the device information delivered from each collection thread 30 and delivers the information to the device list DB 10.

The collection thread 30 has an individually assigned device list 31 and a collection module 32 to collect device information using ICMP / SNMP from the IP device 60 at predetermined collection cycles.

At this time, the collection thread 30 receives the equipment list from the information distribution module 21 according to the determined polling policy and collects the equipment from the equipment.

The polling policy can be properly selected by the network management operator as a device acquisition success / failure threshold (T) and a priority of the device list.

In addition, each device list in the collection thread 30 has a collection success counter (S) and a collection failure counter (F) for each device, so that each collection / failure is incremented by one.

The collection thread 30 moves equipment whose collection success counter exceeds the threshold to the collection success equipment list, and equipment whose collection failure counter exceeds the threshold to the collection failure equipment list, and initializes the counter value to zero.

The IP device 60 collectively refers to equipment constituting an IP network such as a router, a switch, and an access point.

In the first embodiment of the present invention, the collection thread has a device list and a collection module as applied to a general network management system. However, unlike the configuration of the network management system, the collection thread has only a collection module without a device list. It may be. Hereinafter, such an embodiment will be described with reference to FIG. 2.

2 illustrates a configuration of a system for collecting equipment information in network management according to a second embodiment of the present invention.

As shown in FIG. 2, in the network management according to the second embodiment of the present invention, the equipment information collection system includes the first, except for the information distribution module 41, the collection information management module 45, and the collection thread 50. It has the same structure as in the embodiment.

Since the information distribution module 41 is provided with a list of equipment to be collected in the equipment list DB 10 and the devices are not collected, the information distribution module 41 stores the corresponding equipment list as an unidentified equipment list 42.

The collection thread 50 has only a collection module 51, and receives a number of units (42, 43, 44) of the corresponding equipment at a collection priority determined at each collection cycle, and collects the information about the equipment, and collects information on the equipment. Save it to the list.

For example, if the network management operator sets the collection priority in the order of collection success equipment list 44, unidentified equipment list 42, collection failure equipment list 43, all collection threads 50 are collection success equipment. The list is received from the list 44 and the collection is performed.

Thereafter, the collection thread 50 performs the collection in the order of the unidentified equipment list 42 and the collection failure equipment list 43 () when the collection is completed for all the equipments corresponding to the equipment list of the collection success equipment list 44. .

At this time, each equipment list is mutual exclusion through a lock so that the equipment list is appropriately distributed to all collection threads 50.

The collection information management module 45 collects equipment information collected from the plurality of collection threads 50 and delivers the collected equipment information to the equipment list DB 10 as collection information.

Referring to Figure 3 will be described in detail the operation of the equipment information collection system in network management according to an embodiment of the present invention.

3 is a flowchart illustrating a device information collection system in network management according to an embodiment of the present invention.

As shown in FIG. 3, in the method for collecting device information in network management according to an embodiment of the present invention, the network manager first prioritizes a polling policy setting in order of unidentified device list, collection success device list, and collection failure device list. Assume that it is specified.

Next, the central collection apparatus 20, 40 generates N collection threads 30, 50, divides the equipment list DB 10 into N, and collects the collection threads 30, through the information distribution module 21, 41. 50) (S1, S2).

The collection threads 30 and 50 store the allocated device list in the unidentified device list because the device has not yet collected the device list (S3).

At the beginning of the collection cycle, the collection threads 30 and 50 check whether there is a list of unidentified devices, and if there is a list of unidentified devices, the list is taken and the collection of the corresponding devices is performed (S4, S5).

In the above, if the unidentified equipment list is not left, the collection threads 30 and 50 check whether the collection success equipment list remains according to the priority (S6).

The collection threads 30 and 50 obtain and collect the list of the equipment if the collection of successful equipment is left, and check whether the collection of the equipment failed is left if the collection of the successful equipment is not left (S7, S8).

If the collection failure equipment list remains, the collection threads 30 and 50 collect and collect the collection failure equipment list, and wait until the collection end if the collection failure equipment list is not left (S9, S10).

In this case, since each device has a collection success counter and a collection failure counter for each device, the central collection apparatus 20 or 40 increases the collection success counter by 1 when the collection is successful and increases the collection failure counter by 1 when the collection is failed.

After the end of the collection, the central collection unit sees each device list, moves the equipment that the collection success counter exceeds the threshold to the collection success equipment list, and the equipment that the collection failure counter exceeds the threshold to the collection failure equipment list, and changes the counter value. Initialize to 0 (S11).

In the first embodiment, the information distribution module 21 and in the second embodiment, the collection information management module 45 collects the collection information from all the collection threads 30 and 50 and records them in the equipment list DB 10 (S12). )

The central collection apparatus 20, 40 waits until the next collection cycle when the collection cycle is completed, and repeats the above steps when the next collection cycle starts.

Although the preferred embodiment of the present invention has been described in detail above, the present invention is not limited thereto, and various other changes and modifications are possible.

As described above, in the network management according to the present invention, the recording medium on which the system information collection system and method is recorded, the central collection apparatus separately manages the equipment list according to the equipment information collection state of the previous collection cycle, and then collects normally. This has the effect of preventing the list of impossible devices from being biased towards a particular collection thread.

In addition, in the network management according to the present invention, the recording medium in which the system information collection system and method are recorded can be adaptively polled to the equipment state according to a predetermined polling policy, thereby shortening the equipment collection time and performing the previous collection cycle. Since the collection can be performed first on the successful collection of equipment, it is possible to collect as much information of the equipment as efficiently as possible within a predetermined collection cycle and to minimize the number of collection failures.
