Description

  The present invention relates to a technique that allows a person who does not understand SQL to handle SQL sentences in Japanese.

  In a conventional computer system resource monitoring method, a method of monitoring a collection interval as a fixed time is generally used.

  However, in the resource monitoring method with a fixed interval, if the monitoring interval is set wide, there may be a case where the fluctuation of the resource usage rate of the monitored computer cannot be supplemented, and conversely, the monitoring interval is set narrow. In some cases, the monitoring process may cause a resource pressure on the monitored computer.

  To solve this problem, the technique disclosed in Patent Document 1 solves this problem by associating a plurality of thresholds for the resource usage rate of the computer to be monitored with resource monitoring collection intervals for each of the plurality of thresholds. ing.

FIG. 6 shows an example in which fluctuations in the resource usage rate of the computer to be monitored are not supplemented when resource monitoring is performed at regular intervals. The method disclosed in Patent Document 1 in FIG. An example is shown.

  However, with the technique disclosed in Patent Document 1, there is a problem that excessive resource pressure is applied to a computer system with a high resource usage rate during a high load.

  FIG. 8 shows a resource usage rate and a collection interval in a case where the method disclosed in Patent Document 1 is applied to a computer system having a high resource usage rate continuously.

  The present invention has been made to solve the above-described problems. In addition to the method of introducing a plurality of threshold values (hereinafter referred to as threshold values) for the resource usage rate of the computer to be monitored, which is proposed in Patent Document 1, the purpose of the variable is to store the state transition state of the resource usage rate. (Hereinafter referred to as a state transition variable), and a method that has been proposed for supplementing resource monitoring fluctuations and reducing resource pressure in a monitored computer system by associating a collection interval with two indices of a threshold value and a state transition variable To achieve it more effectively.

The present invention relates to a collection interval adjustment system in resource monitoring that adjusts / controls a collection interval of resource usage rate.
Detect that the usage rate exceeds a predetermined threshold, detect a state transition of the ratio between the usage rate and the threshold, increase the collection interval if there are few transitions, and set the collection interval if there are many transitions A collection interval adjustment system for resource monitoring to be shortened is provided.

Further, the present invention provides a collection interval adjustment method in resource monitoring that adjusts / controls the collection interval of the resource usage rate.
Detecting that the usage rate exceeds a predetermined threshold;
Detecting a state transition of the ratio between the usage rate and the threshold;
There is provided a collection interval adjustment method in resource monitoring, which includes a step of lengthening the collection interval if there are few transitions and shortening the collection interval if there are many transitions.

  According to the present invention, it is possible to more effectively realize the resource monitoring fluctuation supplement and the resource pressure reduction of the monitored computer system than the conventionally proposed methods.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  Referring to FIG. 1, a computer 100 as a collection interval adjustment system in resource monitoring in this embodiment includes a monitoring target resource 101, a data processing unit 110, and a storage unit 120.

  The data processing unit 110 includes a performance information collection unit 111, a threshold / state transition variable management unit 112, and a collection interval adjustment unit 113.

  The storage unit 120 includes a performance information storage unit 121, a collection interval setting information storage unit 122, and a state transition information storage unit 123.

  The collection interval setting information storage unit 122 stores data having the structure shown in FIG. 2, and the collection interval setting information storage unit 123 stores data having the structure shown in FIG.

  Next, the operation of the embodiment of the present invention will be described in detail with reference to the flowcharts of FIG. 1, FIG. 2, FIG. 3 and FIG.

  As shown in the flowchart of FIG. 4, the collection interval setting information reading 202 is performed after the activation 201 of the monitoring system.

  Thereby, the setting information of the data structure as shown in FIGS. 6 and 7 is stored in the collection interval setting information storage unit 122 and the state transition information storage unit 123, respectively. At the same time, the performance information collection interval is set to an initial value.

  Thereafter, the first performance information collection 203 is performed using the performance information collection unit 111 based on the set initial value. The performance information collected at this time is stored in the performance information storage unit 121. After the performance information collection 203, a determination process of the collection period end 204 is performed.

  When the determination result is No, the monitoring system performs threshold / state transition variable information collection 205 using the threshold / state transition variable collection unit 112. At this time, the threshold / state transition variable collection unit 112 first checks whether the resource usage rate exceeds a set threshold.

  Here, if there is a change in the performance ratio between the resource usage rate and the threshold value, the collection interval needs to be changed, so the determination in 206 is Yes.

  Next, if there is no change in the performance ratio between the resource usage rate and the threshold, the state transition variable is incremented. As a result, even when the state transition variable exceeds the set state transition set value, the collection interval needs to be changed, so the determination of 206 is Yes.

  If the determination of 206 is Yes, the processing goes through the collection processing adjustment unit 207. If the determination is No, the processing returns to the performance information collection 203 as it is.

  The collection processing adjustment unit 207 uses the collection interval adjustment unit 113 to adjust the collection interval. When there is a change in the performance ratio between the resource usage rate and the threshold, the setting information stored in the collection interval setting information storage unit 122 is referred to, and the collection interval based on the threshold is set. The set value is stored in the state transition information storage unit 123.

  If the state transition variable exceeds the state transition set value, the state transition information storage unit 123 and the collection interval setting information storage unit 122 are referred to and the collection interval is set to be one level longer than the current collection interval. . The set value is stored in the state transition information storage unit 123.

  Performance information collection, threshold value / state transition variable information collection and collection process adjustment in steps 203, 204, 205, 206, and 207 are repeated for the collection period. When the collection period ends, the determination in 204 is Yes and the monitoring system is terminated. 208.

  According to the present embodiment described above, it is possible to improve the accuracy of supplementing fluctuations in the resource usage rate within a range that does not place excessive resource pressure on the computer system. The collection interval shown in FIG. 8 in the method of the above-mentioned Patent Document 1 becomes as shown in FIG. 5 by using the method proposed in this embodiment.

  As described above, by adding the state transition information proposed in the present embodiment to the technique as in Patent Document 1 to the determination criterion for adjusting the collection interval, the collection interval in resource monitoring that is more flexible than before can be increased. Adjustment can be performed.

  Each of the above-described embodiments is a preferred embodiment of the present invention, and various modifications can be made without departing from the scope of the present invention. For example, processing for realizing the functions of the apparatus may be performed by causing the apparatus to read and execute a program for realizing the functions of the computer 100. Further, the program is transmitted to another computer system by a transmission wave via a computer-readable recording medium such as a CD-ROM or a magneto-optical disk, or via a transmission medium such as the Internet or a telephone line. Also good.
