Abstract

PURPOSE:To improve the efficiency of a trace analysis by selecting a trace of a necessary line portion. CONSTITUTION:When a trace printing device 1 is started, one record in a trace data file 1 is read by a trace record read mechanism 3, and an identifier for showing which line is to be traced is fetched. This identifier is decided, a trace of a line portion which has been designated by a trace identifying mechanism 4 is selected and a trace record is converted to a printing format by a printing mechanism 5 and supplied to a printer 6. Accordingly, a processing for omitting an unnecessary trace by outputting a trace of all lines becomes unnecessary, a trace output time can be shortened, and the efficiency of a trace analysis, etc., is improved.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method of printing based on a trace of a communication line that performs communication using a computer.

[Conventional technology]

In the conventional trace printing method, an m-character request comes from outside!
=) Record in the race record file: ff -)'& Read in the order, convert all records to print format, and print them from the printer.

Figure 3 is a block diagram showing a conventional trace printing device. In Figure 2, (2) is a trace record file containing records created according to trace data for all lines, and (3) is (2). (5) is a trace record reading mechanism that reads the code one by one in a fixed order; (5) is a printing mechanism that converts the trace record into a print format and (6) prints it using a printer.

(6) is a printer, and (1) is a trace printing device.

[Problem that the invention seeks to solve]

Since the conventional trace printing method is configured as described above, traces for all lines must be output, and only traces for necessary lines can be output. was there.

The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide a device that can select and print a trace of an arbitrary line from among traces of a plurality of lines.

[Means for solving problems]

The trace printing method according to the present invention selects and prints traces for specified arbitrary lines based on information about which line the traces are included in the trace records constituting the trace record file. It was made in a similar manner.

[Effect]

The trace printing method of this invention eliminates the process of eliminating unnecessary traces by selecting the traces for the necessary lines.The trace output time is also shortened.
The efficiency of trace analysis, etc. is improved.

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to the drawings. 1st
The figure is a block diagram of the present invention, and the same reference numerals as in FIG. 4 indicate the same or corresponding parts, which is a race identification mechanism (4jtt selected trace record of designated line).

FIG. 2 is a flowchart showing the flow of processing in the apparatus shown in FIG. Next, the operation shown in FIG. 1 will be explained with reference to FIG. Trace printing device is activated (step 1)
reads the code in the trace data file and extracts an identifier indicating which line in the record is being traced. (Step 8). Next, determine the identifier in step 9.
).

If it is a trace for the specified line, print it (Step 1)
0), otherwise read the next record (
Proceed to step 8). In step 8, the trace record is converted into a print format and printed by a printer. Next, it is determined whether all records have been outputted (step 11). If they have been outputted, the process ends; if not, the process returns to step 8.

Although a printer is used as the output device in the above embodiment, a display may also be used. Communication lines are physical,
Any logical line is fine.

〔Effect of the invention〕

According to this invention, by selecting traces for the necessary lines using the trace printing method, the process of omitting unnecessary traces is eliminated, the trace output time is shortened, and the efficiency of trace analysis etc. is improved. There is.

[Brief explanation of drawings]

FIG. 1 is a block diagram showing one embodiment of the present invention. FIG. 2 is a flowchart showing the operation of the device shown in FIG. 1, and FIG. 3 is a block diagram showing the conventional device. (11ij) Lace printing device flt, C2rld trace record 77 file, kll is trace record reading mechanism. (41 is a trace identification mechanism, (5) is a printing mechanism, (6)

Claims (1)

[Claims] In a method of printing traces of multiple communication lines for mutual communication between computers, trace record files containing traces of all lines in records in a certain format, trace record files are printed based on a print specification request. It is characterized by having a record selection mechanism that selects records for a specified line, a printing function that converts the records into print format and prints them from a printer, and a function that selects and prints trace records for a specified line. Trace record printing method for communication lines.
