Abstract

Disclosed is a monitoring device etc. which can carry out server load control in the light of the relationship between contents and load fluctuation, configured to monitor one or more servers which perform a processing in response to a request from a client, and transmit a reply to the client, the monitoring device including an operating plan unit which generates an operating plan of carrying out server load control depending on matter-of-interest information or depending on time information, based on access information related to the request and based on a request analysis result obtained by analyzing the request, the access information and the request analysis result being collected from the server, and a control unit which carries out the server load control based on the operating plan when the matter-of-interest information or the time information satisfies an execution condition included in the operating plan.

Claims

1. A monitoring device configured to monitor one or more servers which perform a processing in response to a request from a client, and transmit a reply to the client, comprising:

an operating plan unit which generates an operating plan of carrying out server load control depending on matter-of-interest information or depending on time information, based on access information related to the request and based on a request analysis result obtained by analyzing the request, the access information and the request analysis result being collected from the server; and

a control unit which carries out the server load control based on the operating plan when the matter-of-interest information or the time information satisfies an execution condition included in the operating plan.

2. The monitoring device according to claim 1, further comprising:

a server measuring unit which measures a time required for activating the server, wherein

the control unit carries out the control when a time obtained by subtracting the time required for activating the server from a current time satisfies the execution condition.

3. The monitoring device according to claim 1, wherein

the operating plan unit derives at least one of a relationship between the matter-of-interest information and the number of servers in operation, and a relationship between the time information and the number of servers in operation, based on the access information and based on the request analysis result and estimates the required number of servers depending on the matter-of-interest information or depending on the time information, and generates the operating plan including the estimated number of servers.

4. The monitoring device according to claim 2, wherein

the operating plan unit derives at least one of a relationship between the matter-of-interest information and the number of servers in operation, and a relationship between the time information and the number of servers in operation, based on the access information and based on the request analysis result and estimates the required number of servers depending on the matter-of-interest information or depending on the time information, and generates the operating plan including the estimated number of servers.

5. The monitoring device according to claim 3, wherein

the control unit performs scale-out processing of the server when the number of servers in operation is smaller than the estimated number of servers included in the operating plan.

6. The monitoring device according to claim 4, wherein

the control unit performs scale-out processing of the server when the number of servers in operation is smaller than the estimated number of servers included in the operating plan.

7. The monitoring device according to claim 3, wherein

the control unit performs scale-in processing of the server when the number of servers in operation is larger than the estimated number of servers included in the operating plan, and the number of servers in operation to which more than a predetermined load is applied is smaller than the number obtained by subtracting one from the estimated number of servers.

8. The monitoring device according to claim 4, wherein

the control unit performs scale-in processing of the server when the number of servers in operation is larger than the estimated number of servers included in the operating plan, and the number of servers in operation to which more than a predetermined load is applied is smaller than the number obtained by subtracting one from the estimated number of servers.

9. The monitoring device according to claim 1, wherein

the operating plan unit sets a keyword included in the request from the client, as the matter-of-interest information.

10. The monitoring device according to claim 1, wherein

the operating plan unit extracts a keyword that satisfies a predetermined condition from an information retrieval site via a network, and sets the keyword as the matter-of-interest information.

11. The monitoring device according to claim 9, further comprising:

an operation command issuing unit which transmits the keyword to the one or more servers as an object to be monitored.

12. A server configured to perform a processing in response to a request from a client, and transmit a reply to the client, comprising:

a statistical unit which extracts matter-of-interest information from a request analysis result obtained by analyzing the request, and calculates a degree of interest with respect to the matter-of-interest information, based on access information related to the request; and

a transmitting unit which transmits the degree of interest calculated by the statistical unit with respect to the matter-of-interest information to a monitoring device configured to monitor the server via a network.

13. A monitoring system provided with one or more servers configured to perform a processing in response to a request from a client, and transmit a reply to the client, and a monitoring device configured to monitor the server, the server comprising:

a statistical unit which extracts matter-of-interest information from a request analysis result obtained by analyzing the request, and calculates a degree of interest with respect to the matter-of-interest information, based on access information related to the request; and

a transmitting unit which transmits the degree of interest calculated by the statistical unit with respect to the matter-of-interest information to the monitoring device, wherein

the monitoring device includes;

an operating plan unit which generates an operating plan of carrying out server load control depending on the matter-of-interest information or depending on time information, based on the access information and based on the request analysis result, the access information and the request analysis result being collected from the server; and

a control unit which carries out the server load control based on the operating plan when the matter-of-interest information or the time information satisfies an execution condition included in the operating plan.

14. A monitoring method monitoring one or more servers configured to perform a processing in response to a request from a client, and transmit a reply to the client, comprising:

generating an operating plan of carrying out server load control depending on matter-of-interest information or depending on time information, based on access information related to the request and based on a request analysis result obtained by analyzing the request, the access information and the request analysis result being collected from the server; and

carrying out the server load control based on the operating plan when the matter-of-interest information or the time information satisfies an execution condition included in the operating plan.

15. A non-transitory program recording medium storing a monitoring program of monitoring one or more servers configured to perform a processing in response to a request from a client, and transmit a reply to the client, the monitoring program causing a computer to execute:

a processing of generating an operating plan of carrying out server load control depending on matter-of-interest information or depending on time information, based on access information related to the request and based on a request analysis result obtained by analyzing the request, the access information and the request analysis result being collected from the server; and

a processing of carrying out the server load control based on the operating plan when the matter-of-interest information or the time information satisfies an execution condition included in the operating plan.
