Abstract

PURPOSE:To provide an automatic fault informing device capable of informing fault information corresponding to the level of a fault and generation frequency. CONSTITUTION:An automatic notice reference value designation part 30 sets a fault level for every specification of fault, and designates a notice reference value and notice standby time for every level. The fault level is informed to a decision part 20, and notice reference value information is informed to a fault generation frequency measuring part 40, and notice standby time information is informed to a control part 50. When the fault occurs in a system 60, the fault level decision part 20 decides the level of fault based on the fault information collected by a fault data collection part 10. The fault generation frequency measuring part 40 measures frequency at every specification of fault, and sends out the fault information to the control part 50 when it exceeds a reference value. Standby is instructed for notice time when the frequency measured by the measuring part 40 exceeds the notice reference value, and when the fault to be informed occurs during that time, the information and the fault information exceeding reference are unified in one, then, it is sent out to a public line 70.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fault automatic notification device for automatically reporting fault information in an information system to a maintenance center.

[0002]

2. Description of the Related Art Conventionally, as an apparatus of this type, Japanese Patent Laid-Open No.
The one disclosed in Japanese Patent No. 208747 is known.
In the information disclosed in this publication, when a failure occurs in the information system, the failure level is determined and the number of occurrences for each failure level is counted, and it is specified that the failure level should be automatically notified. If the number of occurrences reaches the notification standard value even if it is specified that the failure level should not be reported automatically, the failure information is reported to the maintenance center. Attempts to report the failure information to the maintenance center.

[0003]

However, in the case disclosed in the above publication, when the failure level does not indicate that automatic notification should be made, for example, in the case of a minor failure, the number of failures at that failure level is generated. When it reaches a preset notification standard value, the failure information is only reported, and failure information is not considered considering the frequency of occurrence of failures, so it is possible to prevent failures before they occur. It was difficult to do.

For example, when 10 faults of a certain fault level occur and the fault information is reported to the maintenance center, 10 faults occur within 2 months.
Such an occurrence frequency does not have a serious influence on the information system, and even in the case where maintenance should be performed at the time of regular maintenance, the failure information is always reported to the maintenance center. Therefore, there is a drawback that the communication cost for reporting the fault information increases.

An object of the present invention is to provide an automatic fault notifying device capable of reporting fault information according to the level of fault and the frequency of occurrence of fault.

[0006]

According to the automatic fault notifying apparatus of the present invention, a collecting means for collecting fault information in an information system, a judging means for judging a fault level based on the fault information, and a fault level Designating means for designating the report reference value and report waiting time for each, measuring means for measuring the occurrence frequency of the occurred fault for each type of fault, and the occurrence frequency measured by the measuring means is designated by the designating means When the specified notification standard value is exceeded, the system waits for the specified notification waiting time specified by the specifying means, and if another failure to be reported occurs during this period, the failure information and the notification reference value. Control means for notifying the failure information of the failure corresponding to the occurrence frequency exceeding.

[0007]

In the present invention, the designating means sets the fault level for each fault type, and further designates the report reference value and the report waiting time for each fault level. Then, when a failure occurs in the information system, the determining means determines the level of the failure based on the failure information collected by the collecting means. Further, the measuring means measures the occurrence frequency of the generated fault for each fault type. When the occurrence frequency measured by the measuring means exceeds the notification reference value specified by the designating means, the control means waits for the notification waiting time designated by the designating means and should report within this period. When another failure occurs, the failure information and failure information of the failure corresponding to the occurrence frequency exceeding the notification reference value are collectively reported.

Therefore, the failure information can be reported according to the frequency of occurrence of the failure according to the level of the failure.

[0009]

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

FIG. 1 is a block diagram showing an embodiment of an automatic fault notification device according to the present invention. In FIG. 1, the fault automatic reporting device 1 includes a fault data collection unit 10, a fault level determination unit 20, an automatic reporting reference value designation unit 30, a fault occurrence frequency measurement unit 40, and an automatic reporting control unit 50. Is configured. In this embodiment, the fault automatic notification device 1
Is realized by the service processor.

The automatic notification reference value designation unit 30 sets a failure level for each failure type based on input information from an input device (not shown), and further specifies a notification reference value and a notification waiting time for each failure level. The failure level is notified to the failure level determination unit 20, the notification reference value information is notified to the failure occurrence frequency measurement unit 40, and the notification waiting time information is notified to the automatic notification control unit 50.

The fault data collection unit 10 collects fault information when a fault occurs in the information processing system 60.
This fault information is sent to the fault level determination unit 20.

The failure level determination section 20 determines, for each failure type,
The failure level of the failure that has occurred is determined based on the specified failure level. When this determination is completed, the failure information is sent to the failure occurrence frequency measuring unit 40.

The failure occurrence frequency measuring unit 40 measures the occurrence frequency of the failure for each failure type, and when the occurrence frequency exceeds the specified notification reference value, the failure information is sent to the automatic notification control unit 50. Send out.

When the fault information is sent from the fault occurrence frequency measuring unit 40, the automatic notification control unit 50 determines whether or not there is fault information on standby (in its own standby area). If the waiting failure information exists, the failure information and the received failure information are combined into one and the public line 7
Send to 0. On the other hand, if there is no waiting fault information, the fault information is made to wait for the designated notification waiting time. If other fault information is transmitted from the fault occurrence frequency measuring unit 40 during this standby, it is transmitted to the public line 70 together with the fault information. The fault information sent to the public line 70 will be input to the maintenance center 80.

Next, FIG. 2 shows a detailed configuration of the fault occurrence frequency measuring unit 40.

In FIG. 2, when failure information is sent from the failure level determination section 20, the failure type determination section 41 determines the failure type, and among the plurality of failure type counters 42 provided for each failure type. The fault type counter corresponding to the determined fault type is incremented. It should be noted that nine failure type counters are provided when there are three failure types and each failure level is three levels. The reset timer 43 is provided corresponding to each failure type counter, and resets each failure type counter at regular intervals. Counter check unit 4
4 checks whether or not the count value of each failure type count exceeds the notification reference value designated by the automatic notification reference value designation unit 30. If it exceeds, the corresponding failure information is sent to the automatic notification control unit. Then, the failure type counter 42 and the reset timer 43 are reset. In other words, when the frequency of occurrence exceeds the notification standard value,
The value of the failure type counter that counts the frequency of occurrence of the failure is reset, and the value of the timer provided corresponding to the failure type counter is reset, and the frequency of occurrence of the failure is measured from the beginning. With this configuration, by counting the number of trouble occurrences within a certain period,
The frequency of failure occurrence can be measured.

Next, the detailed structure of the automatic notification control unit 50 is shown in FIG.

In FIG. 3, when the failure information is sent from the failure occurrence frequency measuring section 40, the communication control section 51 investigates whether the failure information is waiting in the failure information waiting section 53 and waits for it. For example, the information is taken out, and it is reported to the maintenance center 80 together with the fault information sent, and then the timer 52 is reset. When the failure information waiting unit 53 does not wait for the failure information, the failure information waiting unit 53 stores the received failure information, and then the timer 5
Reset and start 2. The timer 53 notifies the notification control unit 51 of the end of the waiting time after the notification waiting time designated by the automatic notification reference value designating unit 30 has elapsed. When the notification control unit 51 receives the notification of the end of the waiting time, it extracts the failure information from the failure information waiting unit 53 and notifies the maintenance center 80, and then resets the timer 52.

The fault information reporting process of the fault automatic reporting device 1 having such a configuration will be described with reference to FIG.
4. FIG. 4 is a flowchart showing the operation of the fault information notification process.

As preprocessing, it is assumed that the automatic notification reference value designating unit 30 sets a failure level for each failure type, and further specifies a notification reference value and a notification waiting time for each failure level.

As shown in FIG. 4, the information processing system 60.
When a failure occurs inside (step 101), the failure data collection unit 10 collects the failure data (step 10).
2) Further, the failure level determination unit 20 determines the failure level according to the type of the failure (step 103). Then, the failure occurrence frequency measuring unit 40 measures the occurrence frequency of the occurred failure for each type (step 104), and further determines whether or not the failure occurrence frequency exceeds the designated notification reference value (step 105). . If the notification standard value is exceeded,
The failure occurrence frequency measurement unit 40 notifies the automatic notification control unit 50 of failure information of the failure type corresponding to the failure occurrence frequency.

Upon receipt of the failure information, the automatic notification control unit 50 waits for a specified notification waiting time, and if another failure to be reported occurs during that period, the failure information and the received information are received. The failure information is collected and notified to the maintenance center 80 (step 106).

In the above-described embodiment, the fault occurrence frequency measuring unit 40 is provided with one fault type counter for the same fault type, but this is set to two fault type counters for the same fault type. The two reset timings are shifted by a half cycle. As a result, it is possible to detect the occurrence frequency of failures without missing any failures that occur continuously near the reset timing. For example, if the failure type counter is set to report the failure information to the maintenance center when the count value reaches 10, and five occurrences occur before and after the reset timing for one failure counter, Depending on the fault type counter, the count value is not counted up to 10. However, since the count value is counted up to 10 by the other fault counters, the faults consecutively generated near the reset timing are not overlooked, and the fault is surely detected. The frequency of occurrence can be detected.

In the fault occurrence frequency measuring unit 40, a warning flag is provided for each fault type, and a warning flag is set for a fault that may soon reach the reporting reference value, and in the automatic reporting control unit 50. When the failure information of a certain failure type is sent from the failure occurrence frequency measuring unit 40, the warning flag of another failure type is referred to, and the designated notification waiting time is shortened based on the reference result. Or extend it and report fault information.

For example, when the count value of the fault type counter corresponding to a certain fault type reaches 10, the fault information is notified to the maintenance center, and when the count value reaches 9, the fault type is dealt with. If it is set to set the warning flag to
When the failure information of a certain failure type is sent from the failure occurrence frequency measuring unit 40, the warning flag is referred to. If no warning flag is set, the designated notification waiting time is set in advance. If the warning flag is set, the specified notification waiting time is extended by the preset time and After the time has passed, report the fault information received. by this,
After waiting for the specified notification waiting time, not only the received failure information is sent, but immediately if there is other failure information that should be reported, the time will be extended and that information will also be reported. On the other hand, when there is no other fault information to be reported, the time can be shortened and only the received fault information can be reported.

As described above, according to the present embodiment, unnecessary notifications can be reduced by controlling the timing of reporting according to the severity of the failure, and the timing can be determined by the frequency of occurrence of failures. By looking at it, it is possible to report valid fault information even if it is a minor fault.
Also, by using the notification waiting time, it is possible to reduce the communication charges for reporting by collectively reporting the failure information of other failures that occurred at a time close to the timing of reporting the failure information. You can Especially, when using a public line, etc., 2
In some cases, it is possible to make multiple notifications, so it is possible to reduce communication costs.

[0028]

As described above, according to the present invention, when a failure occurs in the information system, the determining means determines the level of the failure based on the failure information collected by the collecting means, and measures it. The means measures the occurrence frequency of the generated failure for each type of the failure, and the control means further specifies, when the occurrence frequency measured by the measuring means exceeds the notification reference value designated by the designating means. If there is another failure that should be reported during this period after waiting for the notification waiting time specified by, the failure information and the failure information of the failure corresponding to the frequency of occurrence exceeding the notification reference value will be 1 Since the notifications are collectively made into one, there is an advantage that the failure information can be notified according to the occurrence frequency of the failure.

Even when the frequency of occurrence exceeds the notification standard, the corresponding failure information is not reported immediately, and the failure information of other failures that occurred during this period is also waited for a preset notification waiting time. Since the notification is made together with the corresponding failure information, there is an advantage that the cost required for the notification can be reduced.
