Abstract

PURPOSE:To make it possible to execute the setting of a reference value (RV) for deciding whether the data of a requested event area to be sampled or not at any time from the ON of a power supply up to its disconnection by preparing an RV setting/changing command capable of setting up/changing the RV including an identification (ID) code during the operation of an information processor. CONSTITUTION:The data sampling system is provided with the RV setting up/changing command capable of setting up/changing the RV including the ID code during the operation of the information processor. When the request 6 of an event record having the ID code 1,000 of a task A driven in a processor P1 informed from the task A, a deciding mechanism 3 decides whether the reference values of a processor number, a task number and an ID code stored in an RV storage area 4 coincide with that of the request or not by comparing them. When the processor P1, the task A and the ID code 1,000 coincide with the input, the mechanism 3 decides data sampling, samples the event of the requesting source indicated by the specified parameter values as data and records the sampled results in a data recording file 5. Consequently, the RV can be set up/changed even during the operation of the information processor.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a data collection method, and more particularly to a data collection method for collecting various events occurring within an information processing device into a data recording file.

[Conventional technology]

In conventional data collection methods, reference values for collecting various events occurring within an information processing device are set in a reference value storage area provided for each processor at the time of system generation.

[Problem to be solved by the invention]

In the conventional data collection method described above, a reference value storage area is provided for each processor to set a reference value for determining whether or not to collect various events occurring during information processing as data. This method has the disadvantage that reference values must be set for each processor when generating the system.

Further, the conventional data collection method has the disadvantage that when setting or changing the reference value, the information processing apparatus must be restarted from being powered on. SUMMARY OF THE INVENTION An object of the present invention is to provide a data collection method that allows setting of a reference value for determining whether data of a requested event is to be collected at any time from when the power is turned on until it is turned off.

[Means to solve the problem]

The data collection method of the present invention provides a reference value setting that allows setting and changing reference values that include an identification code that indicates various events that occur within an information processing device to be identified and collected as data while the information processing device is operating. - a determination unit that determines whether or not to collect an event requested from an active task as data based on a change command and an identification code in the reference value set/changed by the reference value setting/change command;
and data collection means for collecting events determined to be collected as data by the determination means into a data recording file as data.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of the data collection method of the present invention.

The reference value storage file 1 shown in Figure 1 has a keyboard (
By executing the manual reference value setting/change command 2 from KB), the reference values of the processor number, task number, and identification code of the task for which event recording is desired are recorded.

FIG. 2 is an information configuration diagram showing an example of the reference values stored in the reference value storage file 1 of this embodiment.

FIG. 2 is an example of a reference value set in the reference value storage file 1 in FIG. 1 by the reference value setting/changing command 2. The reference value setting/change command 2 can be input any number of times from the time the power is turned on until the information processing device is turned off, regardless of whether the information processing device is in operation or not. The reference value continues to be held even after the power is turned on again.

The reference value setting/change command 2 also transfers the contents of the reference value storage file 1 to the reference value storage area 4 located in the determination mechanism 3.
The information can be read out and stored in the computer, and can be referenced by the determination mechanism 3.

Then, the task requesting event recording may indicate its own task number, identification code, and parameter value of the data to be recorded, and cause an interrupt to the determination mechanism 3, as necessary. , requesting event records.

For example, when the determination mechanism 3 is notified of the event recording request 6 having the identification code 1000 of task A from the task A running on the processor l, the determination mechanism 3 determines the processor number stored in the reference value storage area 4; Compare the task number and identification code with the reference values to determine if there is a match. In this case, processor PI, task A,
Since the identification codes 1000 match, it is determined that data should be collected, and the request source event indicated by the specified parameter value is collected as data and recorded in the data recording file 5.

〔Effect of the invention〕

As explained above, the data collection method of the present invention sets reference values for collecting various events that occur within the information processing device as data, from when the information processing device is powered on to when the information processing device is turned off. This has the advantage that settings and changes can be made even when the information processing device is in operation.
