By measuring, it has a function to monitor the service level of business. Here, the response monitoring device 6 monitors responses to a plurality of tasks processed by the server 4 (4-i, i = 1 to n) and the super load processing server 11.

  Access to each business of the response monitoring device 6 is allocated to the appropriate server 4 (4-i, i = 1 to n) and the super load processing server 11 in which the target business is operating by the function of the load distribution device 3. It is.

  Response information collected by the response monitoring device 6 is periodically transmitted to the server monitoring / control device 8.

Control. The server monitoring / control device 8 also changes the setting of assignment of work to each server with respect to the load balancer 3 when the resource usage status for each server exceeds or falls below the threshold defined in the contract. Instruct.

As illustrated in FIG. 2, the server monitoring / control device 8 includes a communication unit 81, a first collection unit 82, a second collection unit 83, a determination unit 84, and an execution unit 85.
The communication unit 81 receives the response information transmitted from the response monitoring device 6.

  The super-load processing server 11 is a server to which a task is assigned when the system load increases and the service decreases.

The outline of the cluster server system of the present invention will be described in detail below.
In the cluster server system of the present invention, the response information transmitted from the response monitoring device 6, the resource information for each server collected by the server monitoring / control device 8 from the server 4 (4-i, i = 1 to n), The contract information managed by the contract management apparatus 9 is periodically referred to. Next, the response information and the contract information are compared to check whether the service level defined in the contract can be maintained. As a result of the check, if it is determined that the predetermined service level has not been reached, a task assignment is added to the superload processing server 11. Subsequently, the resource information is checked, and if the usage record exceeds a predetermined threshold value (upper limit), the server 4 (4-i, i = 1 to n) is the server with the most resources. Add business assignments. On the other hand, if the usage record has not reached the specified threshold (lower limit), check whether the business running on the server is running on another server and running on the other server. Cancel the business assignment only if The server 4 (4-i, i = 1 to n) and the super load processing server by the load balancer 3 after changing the business assignment to the server 4 (4-i, i = 1 to n) and the super load processing server 11 Change the allocation of access to 11.

  Further, in the cluster server system of the present invention, the billing device 10 stores the contract information managed by the contract management device 9 and the server allocation change processing log executed by the server monitoring / control device 8 in accordance with the determined timing. Refer to and calculate the usage fee according to the accounting method specified for each business. For example, when the charging method is based on the maximum usage resource, the usage fee is obtained by multiplying the unit price determined for each resource by the maximum number of resources used in the target period. In addition, for example, when the charging method is based on the average used resource, the sum of the number of resources used during the target period multiplied by the time used for the resource is used as the frequency, and this is determined for each resource. Use price multiplied by unit price. The calculation results are organized for each business or for each user, and billing information is created.

Next, the operation of the best mode for carrying out the present invention will be described using specific examples.
With reference to FIG. 3, the contract information, response information, and server monitoring information used in the present embodiment will be described.
The contract information referred to by the server monitoring / control device 8 is managed in a form as shown in the contract information 31 of FIG. For example, the user “USR00001” is operating two services “SRV1100001” and “SVR1100002”, and the response time threshold (upper limit) is 3.0 seconds as SLA (Service Level Agreement), respectively. It is defined as 0 seconds, and the charging method is defined as charging for the maximum use resource. Note that the SLA is a contract in which contents to guarantee the quality of service provided to the user by the business operator are agreed.

  The response information referred to by the server monitoring / control device 8 is sent from the response monitoring device 6 in the form shown in the response monitoring result report 32 of FIG. For example, it is reported that the response time of the service “SRV1100001” at the time of 2005/12 / 25-10: 00: 00 is 4.0 seconds, which is 1.0 seconds longer than the SLA 3.0 seconds. Indicates that a server needs to be added.

  The server monitoring information referred to by the server monitoring / control apparatus 8 includes the monitoring threshold for each server resource managed in the form as shown in the server resource monitoring definition 33 in FIG. 3 and the server resource monitoring result report 34 as shown in FIG. There is a resource monitoring result for each server collected in the form. For example, the server “SV990001” sets the CPU usage rate to less than 90% and 10% or more. Since the CPU usage rate of the server “SV990001” as of 2005/12 / 25-10: 00: 00 is 65%, it can be seen that the operating status is within the defined range.

The accounting information will be described with reference to FIG.
The transaction allocation change process log referred to by the accounting apparatus 10 is placed on the server monitoring / control apparatus 8 in the form shown in the server allocation change process log 41 of FIG. For example, in the service “SRV1100001”, the number of CPUs used is reduced from 3 to 2 at 2005/12 / 02-22: 00: 00, and the number of CPUs used is increased from 2 to 2005/12 / 25-10: 00: 00. It can be seen that the number is increased to 3.

  As an example of the charging method defined in the contract information, maximum usage resource charging and average usage resource charging will be described using the charging method 42 of FIG. In the maximum usage resource billing, the usage fee is calculated as follows: usage price = unit price (yen / resource / target period) × maximum number of resources used in the target period × usage period. In the average usage resource billing, the usage fee = unit price (yen / resource / time) × σ (number of used resources × usage time). σ represents a mathematical symbol representing the sum. For example, the user “USR00001” has two services “SRV1100001” and “SRV1100002”, and the charging method is set to the maximum resource charging for both. Accordingly, the usage fee is calculated in accordance with the above-described calculation method of the maximum usage resource charging, and charging information as shown in the charging billing information 43 in FIG. 4 is created. In addition, the user “USR00002” has one service “SRV1100003”, and the charging method is set to average usage resource charging. Therefore, the usage fee is calculated in accordance with the above-described calculation method of average usage resource charging, and charging information as shown in the charging request information 44 of FIG. 4 is created.

Next, with reference to FIG. 5, an embodiment of the business assignment change process will be described.
(1) Step S101
The server monitoring / control device 8 refers to the service response monitoring result report during the business assignment change processing.
(2) Step S102
Further, the server monitoring / control device 8 refers to the server resource monitoring report.
(3) Step S103
Further, the server monitoring / control device 8 refers to the contract information.
(4) Step S104
The server monitoring / control device 8 compares the response result with the SLA threshold (upper limit) of the contract information.
(5) Step S105
When the response result exceeds the SLA threshold value (upper limit), the server monitoring / control device 8 adds a work assignment to the super load processing server 11. That is, the service is validated on the super load processing server 11.
(6) Step S106
If the response result does not reach the SLA threshold (upper limit), the server monitoring / control device 8 continues to compare with the SLA threshold (lower limit).
(7) Step S107
If the response result SLA threshold (lower limit) has not been reached, the server monitoring / control device 8 checks whether or not the business is operating on the superload processing server 11. If it is not operating, the process is terminated.
(8) Step S108
If it is operating, the server monitoring / control device 8 cancels the business assignment. That is, the service on the super load processing server 11 is invalidated.
(9) Step S109
When the response result has reached the SLA threshold (lower limit), the server monitoring / control device 8 next refers to the server resource monitoring report and compares it with the threshold (upper limit) of the monitoring definition.
(10) Step S110
When the resource usage rate exceeds the threshold value (upper limit), the server monitoring / control device 8 adds a business assignment to the server having the most resource margin among the servers 4 (4-i, i = 1 to n). . That is, the service is activated on the server 4 with the lowest load.
(11) Step S111
If the resource usage rate does not reach the threshold (upper limit), the server monitoring / control device 8 continues to compare with the threshold (lower limit). If the resource usage rate is not below the threshold (lower limit), the process is terminated as it is.
(12) Step S112
When the resource usage rate falls below the threshold (lower limit), the server monitoring / control device 8 is operating on the other server while the business running on the server 4 (4-i, i = 1 to n) is running. Make sure. If it is not operating, the process is terminated.
(13) Step S113
If it is operating, the server monitoring / control device 8 cancels the business assignment. That is, the service on the server 4 (4-i, i = 1 to n) is invalidated.
(14) Step S114
When the server monitoring / control device 8 completes the change of service assignment (validation / invalidation of service) to the server 4 (4-i, i = 1 to n) and the super-load processing server 11, the load distribution is finally performed. The allocation change of the access to the server 4 (4-i, i = 1 to n) and the super load processing server 11 by the device 3 is performed.

  For example, in the case of the service “SRV1100001” of the above-mentioned user “USR00001”, the response result is 4.0 seconds and the SLA (threshold value) is SLA (threshold value) in the comparison process (104) of the response result and the contract information SLA (threshold value). Since it is 3.0 seconds and it is determined that the response result exceeds the SLA (threshold value), a process of additionally assigning “SRV1100001” to the super load processing server is performed (105). After that, the access allocation to the server 4 (4-i, i = 1 to n) and the super load processing server 11 of the load balancer 3 is changed (114).

Next, an example of the accounting process will be described with reference to FIG.
(1) Step S201
The billing device 10 acquires the contract information managed by the contract management device 9.
(2) Step S202
Subsequently, the billing apparatus 10 acquires an execution log of the server allocation change process held by the server monitoring / control apparatus 8. As a method for acquiring information in steps S201 and S202, a method using e-mail or a method using file transfer is considered as an example.
(3) Step S203
Next, in this embodiment, the charging apparatus 10 checks whether or not the charging method of the service to be charged is “maximum used resource charging” based on the acquired contract information. In the case of maximum usage resource billing, the process proceeds to step S204. In other cases, the process proceeds to step S205.
(4) Step S204
The billing apparatus 10 calculates the maximum use resource billing. From the execution log of the allocation change process acquired in step S202, a log for the accounting target period of the service is extracted to find the maximum number of resources used during the target period. Then, a calculation process is performed by using a value obtained by multiplying the maximum number of resources used by the unit price per period / resource.
(5) Step S205
The billing apparatus 10 checks whether the billing method for the billing process target service is “average resource billing”. In the case of average usage resource charging, the process proceeds to step S206. In other cases, there are only two types of charging methods of “maximum used resource charging” and “average used resource charging” in this embodiment, and the process proceeds to error processing.
(6) Step S206
The charging device 10 calculates an average usage resource charge. From the execution log of the allocation change process acquired in step S202, a log for the chargeable period of the service is extracted. The usage time is calculated for each number of used resources, and the sum of the number of used resources multiplied by the usage time for the number of resources and the unit price per resource / unit time is calculated as a usage fee.
(7) Step S207
Finally, the billing apparatus 10 collects the usage fees for each service obtained in steps S204 and S206 as billing information for each contract user.

  For example, in the case of the above-mentioned service “SRV1100001” of the user “USR00001”, it is known from the contract information acquired in step S201 that the charging method is the maximum use resource charging, and thus the process proceeds to step S204 in step S203. It is judged. In step S204, the allocation process log acquired in step S202 is referred to, and it can be seen that the maximum number of resources (CPU) used by the service “SRV1100001” within this target period is 3 CPUs. Therefore, according to the usage fee calculation method of the maximum usage resource charging method, the usage fee can be calculated as unit price: 10,500 yen / CPU · month × maximum number of used resources: 3 CPU = 31,500 yen. Similarly, a usage fee for the service “SRV1100002” is obtained, and these results are collected as billing information for the user “USR00001” in step S207.

  By repeatedly performing this process on the contract user ID, billing information for each contract user can be created.

  Here, in considering the service level guarantee as the contract content, the present embodiment has been described by using the response time of the business, but it is also conceivable to use the guarantee of the disk capacity and the communication band. Furthermore, it is possible to subdivide according to each use area and time zone, or to combine a plurality of contents. In addition, the number of CPUs used has been described as an example of the resource used as the accounting unit, but it is also possible to use the number of servers, the memory capacity, the disk capacity, or the data communication amount. In addition, the description has been made using two types of charging methods, maximum usage resource charging and average usage resource charging. However, charging is performed in an arbitrary processing unit according to the resource and service form as the charging unit. It is also possible to use event charging, point charging in which points are replaced with monetary amounts and points are added according to usage, or a charging method that incorporates the concept of joint purchase of resources by multiple users.

  The present invention is most effective in an environment with a large number of servers and services to be provided, such as an Internet data center (IDC), an Internet service provider (ISP), and an application service provider (ASP). In addition, even a relatively small system is effective when providing a plurality of tasks with a plurality of servers.

  As described above, when the cluster server system of the present invention processes a plurality of tasks with the plurality of servers 4 (4-i, i = 1 to n) via the load balancer 3, the response monitoring device 6 performs the tasks. If the contract contents managed by the contract management apparatus 9 cannot be satisfied, the server monitoring / control apparatus 8 allocates appropriate work. Further, the server monitoring / control device 8 monitors the resource usage status of each server 4 (4-i, i = 1 to n), and when a predetermined threshold value is exceeded, appropriate work is allocated. The charging apparatus 10 obtains a log of business allocation (configuration) change processing from the server monitoring / control apparatus 8 and performs charging processing in accordance with the contents of the contract.

The features of the present invention are described in detail below.
The present invention relates to a cluster server system connected to the Internet via a load balancer. This cluster server system monitors a resource for each server of a plurality of cluster servers connected to the Internet, and controls a task executed by the cluster server based on the acquired information. The present invention is characterized in that a contract management apparatus that manages information on contract contents for charging based on used resources and charging based on average used resources, and a charging apparatus that performs charging processing based on contract contents are provided.

  In the load balancer, when the response state of the business monitored by the response monitoring device does not satisfy the contract content managed by the contract management device, the process is allocated to the super load processing server.

  In the accounting device, the maximum number of resources used is detected based on the configuration change processing log of the server monitoring / control device, and the accounting processing is performed by the product of the maximum number of resources used, the unit price per hour, and the usage time. And

  Further, the charging device is characterized in that the usage resources for each hour are accumulated based on the business configuration change processing log of the server monitoring / control device, and the accounting processing is performed by the product of the accumulated usage resources and the unit price.
