Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a processing method for automatic separation of information collected by a hardware monitor, and in particular, a processing method for automatically separating information collected by a hardware monitor. The automatic separation of collected information is related to a processing method in which a processing period in a target data processing system is extracted and only hardware collection information within the processing period is selectively collected.

Conventionally, in order to check the operating rate of a data processing system, a hardware monitor is used to collect information on one or more check points artificially set in advance on the data processing system, such as a CPU busy signal or CH
The C busy signal is periodically sampled, and the count value for each unit time is collected as hardware monitor collection information, for example, in a magnetic tape device.

However, the information collected from the above hardware monitor is
They are continuously recorded one after another while the hardware monitor is operating.

For this reason, when the collected information is later processed by the host machine or hardware monitor itself, it becomes extremely complicated to select meaningful information as measurement data from the collected information.

In other words, the state of the hardware monitor connected to the check point point is recorded, the trends that typically appear from the collected information are grasped, and a meaningful section is artificially cut out as measurement data. things are done, but
It becomes extremely complicated.

The present invention aims to solve the above-mentioned problems, and focuses on one type of information or a combination of multiple types of information collected by a hardware monitor to improve the data processing system to be inspected. The purpose of this invention is to extract the processing significant period in and automatically select and collect information in the significant period from the collected information.

Therefore, the automatic collection information processing power method of the hardware monitor of the present invention uses the hardware monitor to collect information on one or more predetermined check points in the data processing system under test. In the method for collecting and processing data using a hardware monitor, a processing significant period in the data processing system to be inspected is extracted based on one or more pieces of information collected by the hardware monitor. The present invention is characterized in that only the above-mentioned hardware monitor collection information within the extracted processing significant period is selectively collected.

This will be explained below with reference to the drawings.

FIG. 1 is an explanatory diagram illustrating one aspect of information collection by a hardware monitor, FIG. 2 shows an example of an automatic separation processing method according to the present invention, and FIG. 3 shows an example of an automatic separation according to the present invention. The figure shows an explanatory diagram explaining the concept of processing.

6-n, 1-1, I-2, . . . Tn represent AND circuits, respectively.

Further, MA, B, C, . . . , Z each represent a check point.

When collecting information using the hardware monitor 2, check points on the information processing system 1 are arbitrarily set to M.

For example, check points M, A, B, C...
・The information on Z, that is, logic “1” or rOJ, is clocked 4
Sampling is performed at a sampling period determined by , and the sampling results are sent to counters 31.3-2. ...

For example, the number of times the logic is "1" at the time of sampling is counted.

Then, the count value is determined by the AND circuits 6-1 and 6 by a signal T which momentarily becomes logic "1" in a period of 1 sec, for example.
-2 and 6-n, the information is sequentially recorded on the collected information recording tape device 5.

Information is collected by the hardware monitor as described above, but even if we consider the case shown in FIG.
Bit information is recorded one after another at intervals of 1 se□□□.

Therefore, it becomes extremely complicated to extract meaningful information as measurement data from the information collected in the tape device 5.

FIG. 2 shows an embodiment of the automatic cutting and processing method according to the present invention, and FIG. 3 explains the concept of the automatic cutting and processing according to the present invention.

In Figure 2, 8-1, 8-2,..., 8-m

In FIG. 3, the horizontal axis represents time, and the vertical axis represents the utilization rate of the data processing system 1 to be inspected.

As shown in FIG. 3, processing in the data processing system 1 generally tends to be concentrated during a period when one job or a plurality of jobs are running.

This period of intensive processing is called the workload period, and the information collected during this period has meaning as measured data, and other periods can generally be considered to have little meaning as measured data. can.

From this, in the case of the present invention, collected data 81.8-2
．． . . , extract count values such as Ml, M2, . . . that tend to increase in accordance with the workload period shown in FIG. Information 8-2 during the period in which the count value exceeds the threshold TH as compared by the circuit 10
, 8-3, . . . 8-(m-2) are selected.

That is, the comparator circuit 10 outputs logic "1" only during the period when Mi≦TH is satisfied, and the AND circuit 11 selects.

In the above, it has been shown that the workload period is extracted using only the count value Mi corresponding to the check point M shown in FIG. It goes without saying that if the period cannot be extracted with high precision, the workload period can be extracted by appropriately combining count values from a plurality of check points.

For example, when collecting information with a limited processing range, such as channel control device CHC, channel control device C
A point where the processing status in the HC appears with high precision may be selected as the check point M.

As explained above, according to the present invention, the information on the significant processing period in the data processing system to be inspected is automatically separated from the collected information collected by the hardware monitor. It is sufficient to perform the analysis process based on the information of the results collected by the user, which greatly eases the analysis process.

In the above explanation, it has been shown that automatic separation uses a hardware device as the processing unit 9, but in general, the manner of information collection varies depending on the type of hardware monitor, and the selection of checkpoint points is generally different depending on the type of hardware monitor. Since the meaning of collected information differs depending on the type of information collected, it goes without saying that it is more effective to use a processing unit for automatic segmentation using software processing in order to provide flexibility.
