Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an information processing apparatus for controlling a local area network (LAN) by a LAN controller, and more particularly to a LAN fault information collecting method.

[0002]

2. Description of the Related Art Conventionally, failure information on a LAN has been collected as follows. That is, a means such as a trace is provided for each communication procedure, and when a failure occurs, this trace is checked and the failure is isolated.

However, in recent years, on a single hardware,
A method of operating a plurality of communication procedures is adopted. In such a situation, in order to collect the failure information, it is necessary to confirm the trace or the like for each communication procedure, and as the communication procedure increases, the failure information collection becomes complicated.

As a prior art for collecting fault information,
Japanese Unexamined Patent Publication No. 2-181562 (hereinafter referred to as "prior art 1") measures the number of failure occurrences during operation with a new file when operating with a new file, and the failure occurrence count is a predetermined allowable number of failures. If it is within the range of, the fault occurrence in this new file is allowed and the operation in the new file is continued,
A new file operation method is disclosed in which the system is switched for the first time when the number of failures has exceeded the allowable number of failures.

As another prior art for collecting fault information, Japanese Utility Model Laid-Open No. 63-121937 (hereinafter referred to as prior art 2) discloses a remote station of a distant monitoring control device in which a line disconnection frequency counter is provided. By providing a line disconnection maximum time measurement timer, a transmission error occurrence counter, etc., and transmitting line fault statistical information to the master station of the remote monitoring and control device at regular time intervals, detailed and time-series line fault statistical information can be obtained. A remote monitoring and control device has been proposed which can be collected in an appropriate manner and can take appropriate measures in line maintenance.

[0006]

In the conventional fault information collection, confirmation of traces and the like becomes complicated as the number of communication procedures increases. Also, in order to simplify the confirmation work, it is necessary to have a program that creates a single trace by matching the traces etc. for each communication procedure, and it is necessary to review it every time the communication procedure increases. There is a point.

[0007] In Prior Art 1, the number of fault occurrences during operation with a new file is measured, and fault information on the LAN is not collected.

In the prior art 2, only the line failure statistical information is transmitted to the master station of the remote monitoring control device at regular time intervals,
The master station must judge whether or not the fault can be tolerated by referring to this line fault statistical information.

An object of the present invention is to provide an information processing apparatus and a LAN failure information collection method capable of early detection of a failure in a control for operating a plurality of communication procedures on a single hardware in a LAN. .

According to the present invention, while being connected to a local area network (LAN),
In an information processing apparatus for controlling a LAN by a LAN controller having a failure statistical information register, the LAN controller is accessed at regular intervals to extract failure information from the failure statistical information register, and the extracted failure information is recorded in a file device. An information recording means, a failure allowable number registration means for registering the number of allowable failures within a fixed time in a file device, and a means for notifying an operator of an alarm when the failure allowable number is exceeded at the time of recording failure information. An information processing device having the information processing device is obtained.

Further, according to the present invention, in a LAN fault information collecting method in an information processing apparatus which is connected to a local area network (LAN) and which controls a LAN by a LAN controller having a fault statistical information register, within a fixed time. Registering the allowable number of allowable failures in the file device, accessing the LAN controller at regular intervals to extract the failure information from the failure statistics information register, and recording the extracted failure information in the file device; A method of collecting LAN fault information including a step of notifying an operator of an alarm when the number of faults exceeds a permissible number when recording fault information.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows a system including an information processing apparatus according to an embodiment of the present invention. The information processing device 10 is connected to a local area network (LAN) 12.
Further, the information processing device 10 is a LAN that controls the LAN 12.
It has a controller 14, and this LAN controller 14
Has a failure statistics information register 16. Information processing device 10
Further, the monitoring timer 18 and the failure information recording unit 20
And an LED 22. The monitoring time is set in advance in the monitoring timer 18, and a timeout signal is sent to the failure information recording unit 20 each time the monitoring time elapses (that is, each time it times out). The failure information recording unit 20 is a function included in the driver FW (not shown),
As will be described later, the LAN controller 14 is accessed to record the failure information. The LED 22 is used to notify an alarm as described later.

The information processing apparatus 10 includes a terminal 28 including a CRT 24 and a keyboard that operates as a registration unit 26.
Is connected. The registration unit 26 is for setting the upper limit of the allowable number of failures within a certain period of time.

A file device 30 is connected to the terminal 28 and the information processing device 10. The file device 30 is, for example, a magnetic disk device. The file device 20 stores the failure information and the allowable failure number.

A LAN failure information collecting method implemented by the system shown in FIG. 1 will be described below with reference to FIG. First, the allowable number of failures within a fixed time is set using the registration unit 26 of the terminal 28 (step S1). For example, when 10 failures per hour are within the allowable range, the allowable failure number is set as "10 cases / hour".

Here, a host program (not shown) that manages data transmission and reception and includes a man-machine interface
According to the data transfer request (step S2) from the driver FW, when the data transmission request indicates transmission (transmission of step S3), the driver FW performs a transmission process to the LAN controller 14 (step S4) to transmit the data. When the request indicates reception (reception in step S3), LA
Reception processing to the N controller 14 (step S5) is performed.

Next, a preset monitoring timer 18
Is timed out (step S6), the driver F
W uses the fault information recording unit 20 to access the LAN controller 14 to obtain fault statistical information from the fault statistical information register 16 (step S7), calculate the number of faults, and store this fault number in the file device 30 ( Step S8). At this time, if the number of main failures exceeds the number of allowable failures registered in advance (NO in step S9),
The driver FW carries out an alarm notification to the operator (step S10). This alarm notification is LED22
Or by displaying on a display device such as the CRT 14.

FIG. 2 shows a screen image of the failure statistical information. Here, whether or not the number of failures exceeds the allowable number is performed by comparing the total number 31 of failures and a preset allowable number.

[0020]

As described above, according to the present invention, it is decided to carry out the failure information collection independent of the communication procedure.
In an information processing device that operates a plurality of communication procedures on a single piece of hardware, a LAN is used regardless of each communication procedure.
It is possible to easily carry out the failure notification in. In addition, since the determination is made based on the number of failures in a certain period of time, it is possible to early detect a decrease in processing capacity on the LAN.
