Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a computer network in which a plurality of computers are connected to each other and used, such as a distributed computing environment represented by a client-server model, and more particularly to maintenance of the computer network. The present invention relates to a computer network management system which is suitable for efficient management.

[0002]

2. Description of the Related Art In a large-scale computer network such as a distributed computing environment, for example, "Nikkei Electronics 1990 6-11 (no. 50).
2) ”(1990, published by Nikkei BP), page 132-
Page 133, or “Nikkei Electronics 19
908-8 (no. 507) "(1990, published by Nikkei BP), pp. 116 to 137, for the purpose of maintaining reliable operation of the network, SNMP (Simple NetworkMa
Centralized network management is performed at one place using a management protocol or the like.

On the other hand, in a client / server model, which is a representative of distributed computing, for example, the above-mentioned “Nikkei Electronics 1990 6-11” is used.
(No. 502) ”(issued by Nikkei BP, 1990), pages 130 to 132, a system using a name server for centrally managing the“ name ”of users and programs in the network. It is managed. This "name server" allows the servers to form a "distributed computing environment" within the network. Without this "name server," the system administrator would have to do administrative work on each machine, such as
When a new user is added or a machine is added, it is necessary to update the management files of all machines in the network for the number of machines, but using the name server is a single operation. Mu. Further, this system management includes one that centrally manages files and directories stored in each computer, and one that individually stores and manages history information of a failure that has occurred in each computer.

Conventionally, the function of managing these systems is provided in each computer such as a server or a client, unlike the function of managing a network. Therefore, the system management means cannot know the network configuration and how each system uses the network. If the system management means does not know the network configuration, for example, the reason why the performance as a total system does not improve is the server performance (CPU or disk access performance), or a communication line with a slow communication speed in the middle. Exists, and it is impossible to distinguish whether there is a problem in the server layout or network configuration. Moreover, it is not known that the communication line charged by the first-class communication carrier is frequently used.

On the other hand, as the network management means, the reason why a specific part of the network becomes a bottleneck cannot be obtained only by the information on the network. As a result, even if a failure occurs somewhere in the distributed computer system, it is not known whether the main cause of the failure lies in the elements constituting the network or the system. For example, when a network component such as a router fails and communication between a client and a server is not possible, conventionally, even if a system management unit is used, the failure of the router cannot be detected. On the other hand, if the server configuration information is defective and communication between the client and the server is not possible, the defect in the server configuration information cannot be detected by using only the network management means.

Perform integrated management.

The operation of the network computer management system 1 will be described below. The network management unit 5
Network devices are regularly polled to collect and store information about the communication network 3. Alternatively,
Information about the communication network 3 may be collected and accumulated by an event report issued by a network device. The system management unit 4 periodically polls the WSs 2a to 2c or collects information about the distributed system by an event report issued by the WSs 2a to 2c. The integrated management unit 6 acquires information about the network from the network management unit 5 and information about the distributed system from the system management unit 4.

The network management unit 5 or the system management unit 4 finds an answer to the inquired information from the accumulated information and returns it to the integrated management unit 6. Alternatively, each may further make an inquiry to the network device or WS 2a to 2c.

Then, the integrated management unit 6 which has obtained the answer further performs any one of the following operations. (A) Notify the administrator through the graphical user interface. (B) Inquire detailed information to the system management unit 4 or the network management unit 5. (C) Do nothing. When performing the operation (b), the operation example (B) described above is followed. In this way, the communication network 3 and the WS and distributed system connected to this communication network 3 can be integratedly managed. Next, an example will be described in which WSs are optimally arranged according to the configuration of the network or the distributed system, the usage pattern of the network, the usage status, etc.

FIG. 3 is a block diagram showing a second embodiment of the configuration according to the present invention of the computer network management system of the present invention. In the second embodiment, the computer network management system 1a includes a network management unit 5a having a network configuration database 10 and a traffic monitor 9, a system management unit 4a having a remote installer 8, and an integrated management unit 6a. Composed. The network configuration database 10 stores a list of managed WSs, a list of communication lines used by the WSs for communication, and a list of connection relationships between the WSs and the communication lines as information related to the network configuration. There is. The list of communication lines includes, for each communication line, identification information for identifying the communication line and the line capacity of the communication line.

The operation of the computer network management system 1a according to the present invention will be described below with reference to FIG. FIG. 4 is a PAD diagram showing an example of a bottleneck detection procedure according to the present invention in the computer network management system in FIG. The integrated management unit 6a of FIG. 3 polls each WS by the traffic monitor 9 of FIG. 3 (step 401), and based on the communication statistical information of each WS, the number of input octets or the output of each communication interface of each WS. Obtain the number of octets and (step 402) and the number of times or time when communication was impossible (step 4).
03). Here, the number of input packets may be used instead of the number of input octets. However, the average size (in octets) of input packets must be obtained or explicitly given. The same applies to the number of output octets.

In addition, the network is built on the basis of TCP / IP (TCP / IP), and the traffic monitor uses communication statistics information using SMP (SNMP). If you want to get all of the WS, instead of polling all WSs, for example, RFC 1271 "Remote Network Monitoring Management Information Base" (RFC1271 "Remote N
etwork Monitoring Manager
ent Information Base ”) or RFC 1513“ Token Ring Extensions to the Remote Network Monitoring MIB ”(RFC15)
13 "Token Ring Extensions
to the Remote Network Mo
It is also possible to obtain the line usage amount for each communication line by polling only the WS having the management information conforming to the monitoring MIB ").

Further, by polling all the above-mentioned WSs, the WS operating as a server such as a file server or a printer server is discovered (step 40).
4) Obtain a list of clients (step 405) and information on client / server load from the server (step 406). Further, with respect to the WS serving as the router and the gateway (step 407), the queue length of the transmission waiting queue (in octet units) and the information about the WS load are obtained (step 409). Then, the information thus obtained is stored in a database or the like (step 410).

Based on the information collected from each WS, the location of the bottleneck in the communication path between each server and client is detected (steps 411, 412). If the location of the bottleneck is detected (step 413), the server function is installed in an appropriate WS so as to avoid the bottleneck (step 41).
4, 415), if necessary (step 416), rebuild the client system to select the server (step 417). In this way, it is possible to detect the bottleneck according to the network configuration and the usage pattern / usage status of the network, and optimally arrange the distributed system. Next, the above bottleneck detection will be described with reference to FIG.

FIG. 5 is a PAD diagram showing the bottleneck detection procedure according to the present invention of the computer network management system in FIG. When polling each WS to obtain the number of input octets or the output octet for each communication interface, the connection relationship between the WS and the communication line in the network configuration database 10 in FIG. 3 is used for each communication line. Derive the line usage. In this example, it is determined in the order of the communication line, the router / gateway, and the server whether there is a bottleneck.

First, for each communication line (step 50
1) Evaluate whether the ratio of the line usage to the line capacity exceeds a threshold value defined in advance (step 50).
2) If the threshold is exceeded, it is determined that the communication line is a bottleneck (step 503). next,
For each router / gateway (step 504), it is evaluated whether the system (WS) load, the queue length for transmission, the number of input octets and the number of output octets exceed a predetermined threshold value (steps 505, 507, 509). If either of them exceeds the threshold, it is judged that the router / gateway is a bottleneck (step 5).
06, 508, 510). Finally, for each server (step 511), it is evaluated whether the system (WS) load, the number of input octets and the number of output octets exceed a predetermined threshold value (steps 512, 514), and one of the threshold values is set. If it is over, it is determined that the server is a bottleneck (steps 513 and 515).

A technique for avoiding the bottleneck thus detected will be described below. When the communication line is the bottleneck, the integrated management unit 6a of FIG. 3 in the computer network management system selects one set of server and client including the communication line in the communication path. If the set of the server and the client can select a communication path (called a new communication path) that does not include the bottlenecked communication line, the integrated management unit 6a of FIG. Route control is performed so that the communication route between them becomes a new communication route. If the new communication path cannot be selected, the integrated management unit 6a in FIG. 3 divides the network into two by the bottlenecked communication line, and installs an appropriate WS from the part where the client exists to install the server function. To choose as.

However, if a server having the same function exists in a portion of the network where the client is divided into two and the server is not a bottleneck,
The integrated management unit 6a in FIG. 3 may select the server. In that case, it is considered that the server function has been installed. The integrated management unit 6a of FIG. 3 installs the server function in the CPU, the disk, and the memory when selecting the WS in which the server function is installed,
It is checked that there is room to operate, and a WS satisfying the above conditions is selected as a target for installing the server function.

When the router / gateway is the bottleneck, the bottleneck is avoided in the same manner. The difference is that a communication path that does not include a router / gateway that becomes a bottleneck is selected as a new communication path, and that a network is created with a router / gateway that becomes a bottleneck.
It is to divide. When the server is a bottleneck, the integrated management unit 6a in FIG. 3 selects an appropriate WS as a target for installing the server function. However, if another server having the same function as the bottleneck exists, the integrated management unit 6a in FIG. 3 may select the server. In that case, it is considered that the server function has been installed. Further, when selecting the WS for installing the server function, it is checked that there is room to install and operate the server function in the CPU, the disk, and the memory, and the W satisfying the above condition is satisfied.
Select S as the target for installing the server function.

Next, the procedure for installing the server function will be described. The integrated management unit 6a in FIG. 3 uses the remote installer 8 in FIG. 3 to install the server function on the selected server, and after the installation is completed, operates the server function. As a procedure for installing the server function, the computer network management system 1a shown in FIG.
There are a technique of installing a server function execution program stored in the server and a technique of copying the server function execution program from a server causing a bottleneck to a system selected to install the server function.

Before installing the server function, ask the administrator (maintenance administrator) who manages the network and WS (client server system) whether or not the server can be installed, and obtain the administrator's permission. You can also start the server installation. Further, if necessary, the client system causing the bottleneck is reconstructed. That is, if the client system is designated by the server designation information as the server causing the bottleneck, the server designation information is changed,
Lets you specify a new server that avoids bottlenecks. As described above, according to this embodiment, it is possible to automatically reconstruct a client / server system that avoids a bottleneck.

The next embodiment will be described with reference to FIG. FIG. 6 is a block diagram showing a third embodiment of the configuration of the computer network management system of the present invention according to the present invention. In this embodiment, the computer network management system 1b includes a network management unit 5b having a network configuration database 10 and a system management unit 4b having a remote installer 8, a remote deinstaller 11, and a server monitor 12. It

The network configuration database 10 and the remote installer 8 are the same as those in FIG. 3, and the remote deinstaller 11 is the server (WS).
It has the function of deleting the server function. The server monitor 12 polls each server and collects information (referred to as server utilization) indicating how much the server is used by the client. For example, the number of clients using the service provided by the server and the sum of all the times the client uses the service provided by the server are set as the server utilization of the server. When the traffic monitor 9 polls each WS, the server monitor 12 may be the traffic monitor 9 described in the second embodiment in FIG.

The integrated management unit 6b finds a server in which the server utilization of each server is below a threshold value designated in advance. If there is a server whose server utilization rate is below the threshold, the integrated management unit 6b searches for a server of the same type. If a server of the same type can be found, the server is set as a new server of the clients of the server whose server utilization rate is below the threshold value. If necessary, it also rebuilds the client.

If there are a plurality of servers of the same type, any one of them may be a new server. Alternatively, for each client, the server closest to the client can be a new server for the client. Alternatively, the server closest to the center of gravity of the client group of servers whose server utilization is below the threshold may be set as a new server. Here, the server closest to the center of gravity of the client group is the server having the smallest total distance between the clients belonging to the client group and the server. Expressed by a mathematical formula, this is a server that minimizes the following formula. Σ dc c ∈ C Here, C represents a client group, and dc represents the distance between the client c and the server. The distance between the client and the server may be, for example, the length of a communication line between the client and the server, or the number of routers or gateways existing between the client and the server.

Finally, the integrated management unit 6b deletes the server function from the server whose server utilization rate is below the threshold value.
Note that the load of the system (WS) can be used instead of the server utilization rate. In this way, it is possible to construct an optimum client server system in which the utilization of the server and the system load are within the range specified by the administrator.
