DETAILED DESCRIPTION OF THE INVENTION [Summary] Regarding an editing process for outputting trace data in a computer, data items to be edited and output in accordance with a processing type of a trace target, such as a command code of a traced program, etc. For the purpose of the trace data output editing processing method, which can easily cope with the change of the editing program without changing, etc., for the output data for each predetermined trace type, the data items to be output from the trace data, Editing information for providing visibility to a line for outputting the data item; and item editing means corresponding to each of the data items, and for the trace data in a predetermined format including the trace type, from the edit information according to the trace type. Each of the item editing means corresponding to the determined data item, It is configured to generate the output data by processing the data item.

[Industrial applications]

The present invention relates to an editing process for outputting trace data in a computer, in particular, a trace data output editing process capable of editing according to the type of processing to be traced and taking into account changes in output data items and the like. About the method.

[Problems to be solved by conventional technology and invention]

A process of monitoring the execution of a process in a computer and collecting predetermined various information indicating the progress of the process is known as a trace, and trace data including the collected information is output as appropriately edited output data as a printing device. Alternatively, it is output to a display device or the like, and is used for analysis of a necessary processing state.

FIG. 4 is a block diagram showing the configuration of the computer. The trace processing unit 1 monitors the execution of the traced program 2 by a known appropriate method. For example, every time the traced program 2 processes a command, for example, The command code at that time is collected as a processing type to be traced, and various kinds of control information and the like as data items are collected from a relevant main storage area of the traced program 2 and output as trace data 3. The format is, for example, processing type, data item 1, data item 2, and so on.

When the output editing processing unit 4 is started after the required execution of the traced program 2 is completed, the trace data 3 is read and edited to generate the output data 5 and output it to an output device such as a printing device. Use it for the analysis of the required situation.

It is needless to say that the output data 5 is desirably edited so that only necessary data is arranged in an easily viewable manner so as to be easily used for the purpose of analysis by the user.

However, in the case of the above example, the data required by the user changes according to the type of command and the like, and editing the data individually complicates the editing process. Can be selected and specified, and a large amount of unnecessary information is output, making it difficult to use. Further, even if it is necessary to add a data item to be output, the program of the output editing processing unit 4 must be changed, so that there is a problem that it is not easy to cope with the problem.

An object of the present invention is to provide a trace data output editing processing method which can be edited according to a processing type or the like of a trace target and can easily cope with a change of an output data item or the like without changing an editing program. And

[Means for solving the problem]

 FIG. 1 is a block diagram showing the configuration of the present invention.

The figure shows the configuration of the trace data output editing processing method,
For output data for each predetermined trace type, edit information data 10 indicating edit information for designating a data item to be output from the trace data 13 and a line for outputting the data item, and corresponding to each of the data items The output editing control unit 11 determines the trace data 13 in a predetermined format including the tray type from the editing information data 10 according to the trace type. Item edit processing unit corresponding to the data item
The output data 15 is generated by controlling to process the data item of the trace data 13 according to 12-1 to 12-n.

[Action]

With the above processing method, the data items required for each trace type and the arrangement on the line on the output data can be specified as edit information data 10 separate from the edit program.
Editing corresponding to the type of processing to be traced can be designated relatively easily, and even when data items to be output are changed, it can be easily coped with by almost changing the editing information data.

〔Example〕

For example, as shown in FIG. 2 (a), the edit information data 10 of FIG. 1 is searched for a predetermined trace type code indicating a trace type, and determines a line flag and an item flag. The table 20 includes a row model table 21 indexed by a row model number designated by a row flag.

The trace type code is, for example, 0010 to 0040 as shown in the figure for the trace types T1 to T4. The row flag column is composed of, for example, flag bits sequentially corresponding to the row models L1, L2,... From the left, and flag bits corresponding to necessary row models are indicated by "1", and others are indicated by "0".

The item flag column includes, for example, flag bits sequentially corresponding to the data items K1, K2,... Of the trace data from the left. The flag bits corresponding to the necessary data items are “1”, and the others are “0”. Represent.

According to this editing information data, for a certain trace type, data items that need to be output are designated by item flags, and the lines in which they are arranged are determined by line flags so as to be determined using a line model as described later. Specify the model number.

The row model table 21 includes terms corresponding to the row model number, and each term represents a row model indicating a data item to be output to an output row by a flag bit having the same configuration as an item flag.

With such a configuration, output data for each of the trace types T1 to T4 is output, for example, in one or two rows as shown in FIG. 2 (b), and data items K1 to K9 are output as shown. In this case, the contents of the necessary editing information data are as shown in FIG. 2 (a), for example.

The output editing control unit 11 of FIG. 1 performs a process for each record of the trace data 13 according to, for example, a process flow shown in FIG. First, when one record of the trace data 13 is read in the processing step 30, a trace type code is extracted from a predetermined data item in the process step 31, and the trace type table 20 is searched by the code to determine a line flag and an item flag.

Next, in a processing step 32, the row model corresponding to the 1 bit set to "1" in the determined row flag is indexed from the row model table 21, and in the processing step 33, the row model and the item flag of the item flag determined earlier are retrieved. Create an edit item flag by logical AND.

Therefore, the edit item flag has the same configuration as the item flag and the line model, and becomes information indicating a data item that needs to be output by the trace type among data items specified by the line model.

Therefore, in the processing step 34, the output editing control section 11 performs an item editing process on the data item corresponding to the bit whose value is “1” in the editing item flag from the item editing processing sections 12-1 to 12-n. Call and execute the processing unit.

For this purpose, each of the item edit processing sections 12-1 to 12-n is provided for each data item, is specified by the address of the entry table 14 indexed by the data item number, and is a record read from the trace data 13 first. Predetermined editing of the data item in charge of, for example, setting the data conversion method for converting the data item to characters or numbers that are actually displayed, performing conversion, and specifying the display position, etc. And a program for outputting the edited result as output data 15. FIG. 2 (b)
In the example, the data item K3 of the trace types T2, T3, and T4 is displayed at the right end, indicating that the display position has been specified at the right end.

When the process of the called item edit processing unit is completed and the process returns to the output edit control unit 11, the process is identified in the processing step 35, and the "1" bit of the edit item flag is associated with the corresponding item edit processing unit 12-1 to 12-12. -N Calls all of them sequentially for processing.

When the processing of one line is completed in this way, the trace line edited in processing step 36 is output to the output device,
In processing step 37, it is identified whether or not all the rows specified by the row flag have been processed, and if there is no processing, the processing returns to processing step 32, and starting from the index processing of the row model for the next row as described above. When all lines specified in the line flag are processed, the editing process of the output data ends.

As is clear from the above processing, the data items and the output lines required for each trace type are specified by combining the line model and the item flag, so that the first of the trace types T2 and T3 as shown in the example of FIG. The row, or the second row of T3 and T4, can be processed by the same row model (L2 or L4) as indicated by the designation of the row flag, regardless of the content, which makes the editing information data 10 necessary. The data amount can be reduced.

By using the editing information data as described above, for example, when it is necessary to add a data item, the item flag of the corresponding trace type and the line model to be used are changed, and the editing of the added data item is performed. May be created, and the corresponding item may be added to the entry table.

In the case of adding a line, it is only necessary to change the designation of the line flag and add a line model. In the case where a trace type is added, one item to be searched by a new trace type is added to the trace type table 20. do it.

Also, when the above various additions occur in combination,
The above changes and additions may be performed in combination. In the case of adding a data item, except that the item of the item edit processing unit and the entry table is added, it can be dealt with by updating the editing information data 10, and in any case, Also, there is no need to change the program of the output edit control unit 11 and the item edit processing units 12-1 to 12-n. Even when an item is added, it is good to newly create and add only an item edit processing unit for editing a new data item without affecting the previous item edit processing units 12-1 to 12-n. I can deal with it.

〔The invention's effect〕

As is clear from the above description, according to the present invention, in the editing process of the trace data output in the computer,
There is a remarkable industrial effect that editing can be performed in accordance with the type of processing to be traced and data items to be output can be easily changed without changing the editing program.
