BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a network status monitoring system, and more particularly to a network status monitoring system for a computer system connected to a communication network and performing connectionless data communication.

0002

[Prior art] In connectionless data communication,
When a communication request occurs, data is divided into packets and sent to the communication network as needed. At this time, in order to ensure data transfer, a response packet is sent back and confirmed for the sent packet, and for the received packet, if an error is detected in the received data or an abnormality is detected in the order of arrival of the packet, Measures are taken to request retransmission if there is a problem.

However, when multiple computer systems communicate simultaneously and the communication network becomes congested, or when noise in the communication network increases due to a failure, the number of retransmissions increases due to packet collisions and errors. Data transfer efficiency may deteriorate and communication failure may occur. In the conventional network status monitoring method to know this in advance, the user interrupts the process, calls the service routine manually, and displays error information such as the number of retransmissions during transmission and reception on the screen from the network statistical information management unit. I was letting it happen.

0004

[Problems to be Solved by the Invention] In the conventional network status monitoring method described above, a user who wants to perform data communication has to interrupt the process and manually call a service routine, which makes the operation cumbersome and reduces network performance. Since it is virtually impossible to know the status in advance, it has the disadvantage that it is not very useful for improving data transfer efficiency or preventing failures.

An object of the present invention is to provide a network status monitoring method that displays the latest network status on a portion of the screen without requiring special operations.

[0006]

[Means for Solving the Problems] The network status monitoring system of the present invention includes: a data transmitter having a function of confirming responses to transmitted packets; a data receiving unit having error detection and arrival order detecting functions for received packets; In a network status monitoring method for a computer system that is connected to a communication network and performs connectionless data communication, the network statistics information management unit includes the data transmission unit and the network statistical information management unit that manages error information detected in the data reception unit. A statistical information management unit includes graph creation means for creating and updating a failure occurrence statistics graph at the latest time point from the error information when the computer system is in an idle state, and a graph creation means for creating and updating a failure occurrence statistics graph at the latest time point on a screen of a display device under predetermined conditions. and display means for displaying on a part of the screen.

Embodiments Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of an embodiment of the network status monitoring system of the present invention.

As shown in FIG. 1, the computer 1 in this embodiment includes a data transmitting section 2 having a function of confirming responses to transmitted packets, and a data receiving section having error detection and arrival order detecting functions for received packets. 3, a network statistical information management unit 4 that manages error information detected by the data transmission unit 2 and data reception unit 3, network hardware 6 that connects to the communication network 10, and an operating system 5 that manages the entire system. It is composed of. Furthermore, the network statistical information management section 4 includes a graph creation means 7 for creating and updating a failure occurrence statistics graph at the latest time point from error information from the data transmission section 2 and the data reception section 3 when the computer 1 is in an idle state; A display means 8 for displaying a failure occurrence statistics graph 11 on a part of the screen of the device 9 is provided.

When the data transmitting unit 2 transmits a transmission packet to the communication network 10 via the network hardware 6, if there is no response within a certain period of time or if a retransmission request is received from the other party, error information is recorded as a line failure in the network statistics. It is sent to the information management section 4. On the other hand, when the data receiving unit 3 receives a received packet addressed to its own station but there is an error and requests retransmission, or when there is an error in the order of arrival of the received packet and requests retransmission, the data receiving unit 3 records the error information as a line failure in the network statistics. It is sent to the information management section 4.

In the network statistical information management unit 4, when the computer 1 is in an idle state according to instructions from the operating system 5, a graph creation means 7 creates a failure occurrence statistical graph at the latest point in an easy-to-read format from the error information and stores it in the memory. do. The contents of this memory are updated whenever the computer 1 is in an idle state, and the latest information is always held in the memory.

The display means 8 displays the contents stored in the memory as a failure occurrence statistics graph 11 on a part of the screen of the display device 9 under predetermined conditions. As a condition for display, for example, when error information is received a specified number of times or more within a certain period of time, it is displayed together with a failure message. FIG. 2 shows an example of a screen display in this case, in which the number of failures that have occurred in the last 5 minutes is displayed as a bar graph every 30 seconds along with an alarm message.

[0013]

[Effects of the Invention] As explained above, the network status monitoring method of the present invention allows a computer system in a communication network to create and update a graph in an easy-to-read format representing the network status using idle status, and Since the information is displayed on the screen according to the situation, network abnormalities can be detected before the network suddenly becomes unavailable and suffers a fatal failure.
