FIG. 10 shows an example of the generated business script. One task is the keyword "ev
Between "ent" and keyword "end", "business name",

In the example of FIG. 10, the business name is “data update”, the start condition is “start at intervals of 30,000 milliseconds”, the basic processing elements to be executed are “time stamp acquisition (acquisition point number 0)”, and “128 from file aaa” Byte-sequential read "," CP for 20,000 steps "
U processing ”,“ 128-byte sequential writing to a file named bbb ”, and“ time stamp acquisition (acquisition point number 1) ”.

Here, the method of generating the business script will be described in a little more detail.

FIG. 15 is a diagram showing the structure of a table that stores information for one task in the task flow storage area 407. The table is an area 15 for storing business names.
01, area 1502 for storing execution node address, area 1503 for storing start condition and its parameter, area 1504 for storing measurement point setting method, area 1506 for storing type of basic processing element and its parameter
Consists of Multiple basic processing elements and parameters 15
06 creates a list-like data structure by the pointer 1507 to the next basic processing element, and the pointer indicating the head of the list is stored in 1505. Business flow input section 4
The information representing the business flow input through 02 is temporarily stored in the business flow storage area 407.

The business script generation unit 404 generates a business script as shown in FIG. 10 while referring to the information stored in the business flow storage area 407. FIG.
[Fig. 6] is a flowchart showing a procedure for generating this business script. Hereinafter, a method of generating a business script for one business will be described with reference to FIGS. 15 and 16.

First, the business script generator 404 resets the measurement point number counter as an initialization process for generating a business script (step 1601),
The contents of the pointer 1505 to the head of the basic processing element list of FIG. 15 are stored in the basic processing element pointer and initialized (step 1602). The measurement point number counter and the basic processing element pointer are work tables necessary for generating the business script and are included in the business script generating unit 404.

Next, an event row is generated (step 1603). Since the event line includes the business name and the start condition as information, the business name 1501 and the start condition 150
3 and are read and converted into the expression format in the business script.

Next to the event line, a TimeStamp line for acquiring the time at the start of work is generated (step 1604). In the TimeStamp line, the measurement point number is added as a parameter. The value of the measurement point number counter is used as this value. TimeS
After the output of the ramp line, 1 is added to the value of the measurement point number counter (step 1605).

Next, all the contents of the series of basic processing elements are converted into the expression format in the business script and output.
The basic processing element pointer is used to indicate up to which basic processing element the conversion into the business script is completed. The following processing is repeated until the basic processing element pointer becomes a NULL pointer, that is, a value indicating that it does not point to any basic processing element (step 1606).

First, the contents of the basic processing element 1506 pointed by the basic processing element pointer, including the parameters, are converted into an expression format in a business script (step 1607). Then, the value of the pointer 1507 to the next basic processing element is stored in the basic processing element pointer and updated so as to point to the next basic processing element 1506 (step 1608).

Next, when the setting of the measurement points is "measure all points", a process for acquiring the time stamp after the execution of the basic processing elements is generated. for that reason,
First, the content of the measurement point 1504 is confirmed (step 1609), and if it is “all point measurement”, TimeS
A line "tamp" is generated (step 1610), and 1 is added to the value of the measurement point number counter (step 161).
1). The processing contents of steps 1610 and 1611 are the same as steps 1604 and 1605.

When the above processing is completed for all the basic processing elements, the time stamp acquisition processing when the setting of the measurement point is "first and last" is generated. Check the contents of the measurement point 1504 (step 1612),
If it is "first and last", a TimeStamp line is generated (step 1613). This process is step 16
The same as 04.

Finally, the end line is generated (step 16
14), ending the generation of the business script for one business.

The above processing is performed for all input business flows to generate all necessary business scripts.

When the business script is generated, the business script is delivered to the business flow simulation unit 105 of each information processing apparatus 101 (steps 503 and 510). The business script generation unit 404 divides the business script into an appropriate size and transmits it via the communication processing unit 401, and the communication processing unit 301 receives and assembles the business script divided in the previous period, and the business script area The business script is stored in 302.

After the delivery of the business script is completed, it waits for the operator to issue a measurement start instruction to the measurement execution / stop instruction section 403 (step 504). Upon receiving the measurement start instruction through the measurement execution / stop instruction unit 403, the measurement execution state management unit 405 broadcasts a measurement start time message to all the business script execution units 303 via the communication processing units 401 and 301. At the same time as the transmission, the measurement execution state is held as an internal state, and the operator waits for a measurement stop instruction (step 505).

Upon receiving the measurement start instruction message (step 511), the business script execution unit 303 starts simulation of the business flow according to the contents of the business script area 302 (step 512). See Figure 6 for details.
This will be described later with reference to FIG.

When the measurement execution state management unit 405 receives a measurement stop instruction from the operator through the measurement execution / stop instruction unit 403 during measurement execution, the measurement execution state management unit 405 sends the instruction to all the business script execution units 303. The measurement end instruction message is broadcast and notified, and the fact that the measurement is stopped is held as an internal state (step 506).

Upon receiving the measurement stop instruction message (step 513), the business script execution unit 303 stops the simulation of the business flow being executed, and the performance measurement result table 30
The contents of No. 6 are transmitted to the measurement result analysis / display unit 406 through the communication processing units 301 and 401 (step 514). The contents of the performance measurement result table 306 will be described later.

Upon receipt of the performance measurement result (step 507), the measurement result analysis / display unit 406 displays the content by a display means such as a display and notifies the operator (step 508). A display example of the measurement result will be shown later.

The above is the performance evaluation procedure by the performance evaluation system using one embodiment of the present invention.

Next, details of the method of simulating the business flow by the business flow simulating unit 105 will be described. FIG. 6 is a flow chart showing a method of simulating a business flow, and shows the details of the processing of step 512 in FIG.

When the business script execution unit 303 receives the measurement start instruction message from the performance evaluation management unit 106 via the communication processing unit 301, it first determines whether the business to be simulated is started by a timer.
It is determined from the contents of No. 2, and if it is activated by the timer, the task activation timer of the timing processing unit 304 is activated (step 601), and the event waiting loop is entered (step 602). The event here includes a timeout notification from the business activation timer, a message reception notification from the communication processing unit 301, and the like.

When an event occurs, it is first determined whether the event is the reception of a measurement end instruction message from the performance measurement management unit 106 (step 603).

If the measurement end instruction message is not received,
A sequence of basic processing elements corresponding to the occurred event is read from the business script area 302 (step 604),
The basic processing elements are executed in order. The execution of the basic processing elements is performed by the basic processing element execution unit 30 corresponding to each basic processing element.
This is done by calling 5. It is a module that actually executes basic processes of business such as file reading and writing in the basic processing element execution unit 305 according to the parameters described in the business script.

In this embodiment, acquisition of a time stamp for performance measurement is also positioned as one of the basic processing elements. The time stamp is acquired by reading the time from the clock processing unit 304 and storing it in the performance measurement result table 306. FIG. 11 shows an example of the contents of the performance measurement result table 306. The performance measurement result table 306 has 1
For each time stamp acquisition, three items of a business name 1101, an acquisition point number 1102 which is a numerical value for identifying a measurement point in one business, and a time 1103 are recorded. Even when a plurality of jobs are described in the job script area 302, they are recorded in order of time in one performance measurement result table 306. When the execution of the series of basic processing elements is completed, the process returns to the event occurrence waiting in step 602 (step 606).

If the event occurred in step 602 is the reception of the measurement end instruction message, step 6
If the business activation timer is started in 01, it is stopped (step 607), and the simulation of the business is terminated.

FIG. 14 is a diagram showing an example of the measurement result displayed by the measurement result analysis / display unit 406 after the measurement is stopped.
In this example, the measurement result of the processing time of the “data update” operation executed at the execution node address 10 is graphed. The horizontal axis 1401 is the time when the business is started, and the vertical axis 1402 is the time required to execute the business, for the purpose of observing changes in the processing time of the business. This graph calculates and plots the processing time of the started work from the contents of the performance measurement result table 306 collected from the work flow simulation unit 105. Specifically, for each started job, the processing time of the job is obtained by subtracting the time of the acquisition point at the start of the job from the time of the acquisition point at the end of the job, and plotted in a graph. From the graph of FIG. 14, the processing time in the normal state of the “data update” work is around 0.8 seconds (point 140
3), but due to factors such as competition with other businesses,
It can be seen that this can occur even when it takes about 1.5 seconds (point 1404).

FIG. 12 shows the configuration of a business flow simulation unit according to another embodiment of the present invention. In this embodiment,
One information processing device can simulate the work of a plurality of virtual information processing devices. In the figure, reference numeral 307 denotes a virtual device correspondence table indicating which physically existing information processing device executes the virtual information processing device. Also, the job script area 302
Prepares a plurality of job scripts corresponding to each virtual information processing apparatus so as to store a job script of a job executed by each of the plurality of virtual information processing apparatuses.

FIG. 13 shows an example of the virtual device correspondence table 307. 1301 is a virtual device number for identifying a virtual information processing device, and 1302 is a network address of a physically existing information processing device. In this example, the virtual information processing device with virtual device number 1 is a physically existing device with network address 10.0.0.1, and the virtual information processing devices with virtual numbers 2 and 3 are network address 10 0.0.2 represents that each of them is simulated by a physically existing device.

Even when the performance evaluation is carried out by this configuration, the procedure shown in the flowchart of FIG. 6 is basically carried out. However, a part of the processing of the flowchart of FIG. 6 is changed as follows.

First, in the event occurrence check in step 602, processing is added to determine which virtual information processing device the event occurred that initiates a job to be executed. Therefore, regarding the time-out event, at the time of starting the job activation timer in step 601, the virtual device number of the virtual information processing device on which the job is executed is passed as a parameter to the clock processing unit 304. Ask for the virtual device number. For message receive events,
Store the destination virtual device number in the message,
The virtual device number is used as it is to identify the business to be activated.

In step 604, the job script is read out by selecting from a plurality of job script areas 302 the job script corresponding to the virtual device number obtained when the event occurred in step 602.

Upon execution of the basic processing elements in step 605,
When exchanging a message with another virtual information processing device, the basic processing element execution unit 305 requests the communication processing unit 301 to send a message by designating all communication partners with virtual device numbers. The communication processing unit 301 retrieves the specified virtual device number from the virtual device correspondence table 307, obtains the network address of the physically existing information processing device to which the virtual device number is assigned, and requests the transmission. Message is sent to the network address.

As described above, the work executed by each of the plurality of information processing devices can be simulated by one information processing device, and the work can be simulated by using a system smaller than the actual operation. It will be possible to evaluate the performance of the actual machine.

[0051]

According to the present invention, it becomes possible to easily simulate the work contents on an actual machine even before the application for executing the work is created on the network system. As a result, it is possible to evaluate the performance in advance even for network systems that are difficult to simulate by modeling.

Further, by implementing the simulated work content by combining the basic processing elements, it becomes easy to describe the work content, and by adding a new basic processing element, it is applied to the preliminary performance evaluation of a wide range of systems. become able to.

Further, even if the network system for executing the performance evaluation is smaller than when actually operating, it becomes possible to reproduce the state close to the actual operation,
It is possible to evaluate the system performance in advance without constructing the system of the same scale as the actual operation.

From the above, it is easy to extract in advance the performance defects and the like which are found after the network system is developed, and there is an effect that the period and cost required for constructing the network system can be reduced.
