A function that periodically collects the number of times and the usage rate of the external storage device, etc., and also collects job information at the same time and outputs it to the system operation status recording data file, and then outputs the contents as a list from the output device. Is provided.

[Problems to be Solved by the Invention]

With the conventional functions described above, it becomes possible to output the resource operation status data and job information of each resource of the computer system as a list from the output device, and by analyzing it, a performance problem occurs in the operation of the system. It becomes possible to know whether or not there is.

However, in the conventional computer system, the resource operation status data and job information of each of the collected resources are simply output in the order in which they are collected, that is, in a time series. Therefore, it is necessary to manually find resource operation status data that indicates that a performance problem has occurred, which requires a lot of time and specialized knowledge on the performance problem of the computer system. Therefore, if you are not a specialist in performance analysis / diagnosis, it may be difficult to determine whether or not a performance problem has occurred, and it is necessary to extract information that can be a clue for solving the performance problem. Was even more difficult. Under such circumstances, there is a problem that the improvement work for effectively operating the computer system is delayed as a result.

The present invention has been made in view of the above circumstances, and an object thereof is to automatically extract data from the system operation status record data file that can grasp the status of a performance problem if it occurs. It is to provide a method for editing and outputting performance monitoring information of a computer system capable of outputting.

[Means for solving the problem]

The performance monitoring information edit and output method for a computer system according to the present invention is a job information including resource operation status data including a collection time periodically collected for each of the resources constituting the computer system and a collection time collected at the same time. By analyzing the system operation status record data file for recording and determining whether a performance problem has occurred during the operation of the computer system, the resource operation status data and the job collected when the performance problem occurs A method for editing and outputting performance monitoring information of a computer system that edits and outputs information, including performance reference value data storage means for storing performance reference value data, and all the resource operation statuses recorded in the system operation status record data file. The data is compared with the performance reference value data stored in the performance reference value data storage means, and the performance reference value data is satisfied. If the resource operation status data exists, it is determined that a performance problem has occurred at the time when the resource operation status data is recorded in the system operation status record data file, and the performance reference value data is not satisfied. The resource operating status data, the resource operating status data of other resources collected at the same time as the resource operating status data, and the job information collected at the same time are extracted from the system operating status recording data file. , And performance monitoring information edit / output means for editing them for each performance problem occurrence time and outputting them to the output device.

〔Example〕

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

Referring to FIG. 1, an embodiment of the present invention is directed to an external storage device 1 for storing a system operation status record data file 2, a performance monitoring information edit output means 3, and an external storage device for storing performance reference value data 5. A device 4 and an output device 6 for outputting performance monitoring information are included.

The system operation status record data file 2 in the external storage device 1 includes resource operation status data periodically collected for each of resources constituting the computer system, such as the central processing unit, main storage device, and external storage device, and the same time. This is a file that records the job information collected in. Such resource operating status data and job information are collected by a known operating status collecting function provided in the computer system. That is, the operating status collection function collects the operating status of each resource and the information related to the job by the sampling process for each elapse of a predetermined interval time, and collects one resource operating status data of one resource and one job of one job. Each piece of job information is recorded as one record in the system operation status record data file 2. Here, the internal format of each record differs between the resource and the job, and for each target resource,
The common point is that they are sampled at the same sampling time and the same interval time. FIG. 2 shows a part of the contents of the system operation status record data file 2. In the resource operation status records R1, Ri, and Rx related to resources, in addition to format items such as record ID, record length, sampling time, and interval time, some of them are omitted in FIG.
Data indicating the resource operation status, such as the number of misses in the entire system, the number of misses in the system domain, and the number of misses in the user domain, are included for the main storage device, and the usage rate, wait queue length, etc. are included for the external storage device, For the central processing unit, the usage rate is included. Although not shown in FIG. 2, the job information record includes data such as the central processing unit usage time, elapsed time, number of missing times, and number of input / output times. In addition,
The data indicating the resource operating status and the job-related status indicate the status from the last sampling time to the sampling time.

Referring again to FIG. 1, the performance reference value data 5 stored in the external storage device 4 is data relating to the performance reference value possessed by a performance analysis / diagnosis expert or the like, and this data is the performance monitoring information editing output means. Referenced by 3. Referring to FIG. 3 showing an example of the performance reference value data 5, the performance reference value of the central processing unit is “20% <usage rate <90%”, and the performance reference value of the main memory is system miss count <10. Times /
Seconds "," User missing count <job multiplicity x 2 times /
Second ”, the performance standard value of the external storage device is“ usage rate <30
% ”And“ wait queue length <0.5 ”.

The performance monitoring information edit / output means 3 of FIG. 1 uses the system operation status record data file 2 in the external storage device 1 to perform resource operation status data that does not satisfy the condition of the performance reference value data 5 in the external storage device 4. If there is resource operation status data that does not satisfy the performance reference value data 5, the specified information in the resource operation status data of each resource collected at the same time as the resource operation status data is searched. This is means for editing the job information being executed at that time and outputting it from the output device 6, and an example of the processing is shown in FIG.

Hereinafter, the process of the performance monitoring information edit output means 3 for the system operation status record data file 2 will be described in detail.

Referring to FIG. 1, FIG. 2, FIG. 3 and FIG.
When the performance monitoring information edit output unit 3 is activated, first, the system operation status record data file 2 of the external storage device 1 is
Is opened (step 41) and it is determined whether or not there is a record in this file 2 (step 42). If it is determined in step 42 that there is a record, one record is taken out (step 43).

Next, when the retrieved record is a record showing the operating status of the central processing unit, the information of the usage rate of the central processing unit shown in this record is set in the performance reference value data 5 of the external storage device 4. It is determined whether or not the performance standard value of the usage rate of the central processing unit is satisfied (step 4
Four). When it is determined in step 44 that the usage rate of the central processing unit does not satisfy the performance standard value, the time when the usage rate of the central processing unit related to the record was collected in order to edit and output the corresponding record later. (Sampling time described in the record) is stored internally (step 45).

If the retrieved record is a record indicating the operating status of the main storage device, the information about the number of misses of the main storage device (system missing count, user missing count) shown in this record is stored in the external storage device 4. It is determined whether or not the performance reference value of the number of missing times of the main storage device set in the performance reference value data 5 is satisfied (step 46). When it is determined in step 46 that the number of misses in the main memory does not satisfy the performance reference value,
In order to edit and output the record later, the sampling time indicating the time at which the number of misses of the main storage device for the record was collected is internally stored (step 4).
Five).

Furthermore, when the retrieved record is a record indicating the operating status of the external storage device, the information of the usage rate of the external storage device and the waiting queue length shown in the record is the performance reference value data 5 of the external storage device 4. It is determined whether or not the usage rate of the external storage device and the performance standard value of the waiting queue length are satisfied (step 47). When it is determined in step 47 that the external storage device usage rate and the wait queue length do not satisfy the performance reference value, the external storage device usage rate and the wait time related to the record are edited and output later. The sampling time indicating the time when the queue length was collected is stored internally (step 45).

If the record retrieved in step 43 is not the resource operation status record of each resource but the job information record or the like, it is ignored and skipped in the processing at this point.

When the performance monitoring information edit / output unit 3 completes all the checks by the performance reference value data 5 for all the records stored in the system operation status record data file 2, that is, when it is determined as NO in Step 42, the system operation is once performed. Close the situation record data file 2 (step
48). Here, the reason why not only the sampling time is stored and the edited output of the corresponding data is not processed by opening and closing once is that each record in the system operation status record data file 2 is stored to some extent in time series. However, when focusing on the resources and jobs targeted by individual records, the storage order of the records is irregular. The performance monitoring information edit output unit 3 finally wants to edit and output the operation status data and job information of each resource at an arbitrary time into one, for example, step 44
Even if it is determined that there is a problem in comparing the record related to the central processing unit at a certain time with the performance reference value data 5, the records for the main storage device and the external storage device at the same time have already been checked and the performance is still poor. This is because it may have been determined that there is no problem. In other words, even if a grab of a certain time is caught, there is a possibility that the desired record may already be skipped at that time.

Due to the above circumstances, the performance monitoring information edit output means 3 has a performance problem in comparison with the performance reference value data 5 in the external storage device 4 from the record group of the system operation status record data file 2 in the external storage device 1. Only the sampling time in the record judged to be present is stored internally,
The system operation status record data file 2 is once closed (step 48).

The performance monitoring information edit output means 3 then opens the system operation status record data file 2 of the external storage device 1 again (step 49), and determines whether or not there is a record in this file 2 (step 4A). If it is determined in step 4A that there is a record, one of the records is extracted (step 4B), and the extracted record has a resource operation status record or job having a sampling time that is the same as the sampling time internally stored in step 45. Determine whether it is an information record (step
4C). If it is determined in step 4C that the record is at the corresponding sampling time, an item indicating information serving as a clue for solving the performance problem from that record, for example, a device identification name, a usage rate, etc., for a record related to the central processing unit , The number of system misses, the number of user misses, etc. for the record related to the main memory, the device identification name, the usage rate, the waiting queue length etc. for the external memory, the job name for the job information, the central The processing device usage time, elapsed time, number of missings, number of inputs and outputs, etc. are extracted and stored internally in association with the sampling time (step 4D). By performing the processing from step 4B to step 4D for all the records in the system operation status record data file 2, the performance of the operation status data of each resource at the performance problem occurrence time stored in step 45 Information serving as a clue for problem solving and job information executed at that time are stored internally corresponding to the sampling time.

Next, if the performance monitoring information edit output means 3 determines in step 4A that there is no record in the system operation status record data file 2 that should be processed anymore, then there is data to be edited and output stored in step 4D. It is determined whether or not (step 4E). Then, when it is determined in step 4E that there is no data to be edited and output, the result of analysis of the system operating status record data file 2 is a determination result indicating that no performance problem has occurred in the computer system. Output (step 4G) and close the system operating status record data file 2 (step 4G).
H), the process ends. On the other hand, when it is determined that there is data to be edited and output in step 4E, a data group at the same time in the data is collected, and the performance monitoring information list in the format as shown in FIG. 5, for example, is edited and output from the output device 6. Yes (step 4F). Then, the system operation status record data file 2 is closed (step 4H), and the processing is ended.

By comparing each record in the system operation status record data file 2 in the external storage device 1 with the performance reference value data 5 in the external storage device 4 by the performance monitoring information edit output means 3 which functions as described above. It is determined whether or not each record includes data that can be determined to have a performance problem, and if so, the output device 6 edits and outputs the data together with the related data, as shown in FIG. Thus, it becomes possible to carry out performance monitoring work for operating a computer system efficiently without resorting to a specialist in performance problems.

〔The invention's effect〕

As described above, the performance monitoring information edit output method of the computer system of the present invention preliminarily stores data that can be determined as a performance problem from the recorded data of the operating status of each of the resources constituting the computer system. In order to operate the computer system efficiently, it finds out based on the set performance reference value data, and edits and outputs information that is a clue for solving the performance problem and information about the job that was being executed at that time. There is an effect that the performance monitoring work of can be performed without relying on a specialist of performance analysis / diagnosis.
