Abstract

PURPOSE:To improve the reliability of a device by storing the present time at the time of restoring a monitoring device which is abnormally stopped in a log data storage device as operation stop log data so as to complement it. CONSTITUTION:The present time is stored in a present time storage part 4 by a time storage means 6 every time required for complementing log data when log data on a monitored device is normally stored in a log data storage part 2. When the monitoring operation of the monitoring device where the cause of abnormal stop occurs and the collection operation of log data is stopped is restored, a log data storage complementing means 8 refers to the final log data storage area of the log data storage part 2. When the stored data is not operation stop log data, the final time in the present time storage part 4 is stored in the log data storage part 2 as operation stop log data. Log data is collected by using a stored time from the monitored device so as to complement log data.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an operation stop log data complementing method for complementing operation stop data at abnormal stop.

Computer systems, communication systems and the like are composed of a large number of constituent devices. For example, a multimedia multiplexed transmission system. It is inevitable that a failure will occur in those constituent devices. Therefore, in order to maintain the normal operation of the system and the like, it is necessary to constantly monitor the normality of the plurality of constituent devices,
It is also necessary to prevent the log data collecting function from exerting an influence on the logging function due to the abnormal operating state even in the abnormal operating state occurring in the logging function occurring in the monitoring device itself.

[0003]

2. Description of the Related Art A conventional logging device 52 of a monitoring device 50 continuously collects log data generated in each constituent device (monitored device) 54 such as a computer system into a log data storage area 56 for 24 hours. ing. In the middle of this collection operation, collection of log data may be stopped. This stop is performed by the logging function unit 52 in response to the operation stop signal issued from the operation start / stop instruction unit 58.
Stores the operation stop log data in the log data storage area 56 subsequent to the log data collected so far.
Further, when the log data collection by the logging function unit 52 is resumed, the operation start / stop instruction unit 58 issues an operation start signal to start the operation.

[0004]

In this conventional method, when the operation start / stop instruction section 58 responds to the operation as described above, the log data transmitted from the monitored device 54 is followed by the operation stop log data. Log data storage device 56
However, in the case of abnormal power-off of the monitoring device 50 or the like, the operation stop signal is changed to the logging function 52.
Is not notified, the operation stop log data in that case cannot be stored in the log data storage device 56, and the operation stop log data will be lost when the power is abnormally turned off.
Therefore, troubles such as trouble analysis using the log data occur.

The present invention was created in view of the above technical problem, and an object thereof is to provide an operation stop log data complementing system capable of complementing logging of operation stop log data at the time of abnormal stop. And

[0006]

FIG. 1 shows a block diagram of the principle of the present invention. As shown in FIG. 1, the invention according to claim 1 is a monitoring device that stores log data of a monitored device in a log data storage unit 2, in a current time storage unit 4 and at every time necessary for complementing the log data. When there is no operation stop log data as the stored log data in the final log data storage area of the log data storage unit 2 at the time of recovery from an abnormal stop, A log data storage control means 8 for storing the last time in the current time storage unit 4 in the log data storage unit 2 as operation stop log data is provided.

According to a second aspect of the present invention, as shown in FIG. 1, the time interval at which the current time is stored by the time storage means 4 in the operation stop log data complementing method according to the first aspect is a constant cycle. It is characterized by being.

[0008]

The current time is stored in the current time storage unit 4 by the time storage unit 6 at each time necessary for complementing the log data when the log data of the monitored device is normally stored in the log data storage unit 2. Stored in.

When such a log data collecting operation is continued, an abnormal stop cause occurs in the monitoring device and the log data collecting operation is stopped. When the monitoring operation of the monitoring device is restored, the log data The storage complementing unit 8 refers to the final log data storage area of the log data storage unit 2, and when the stored log data is not operation stop log data, the storage complement unit 8 sets the final time in the current time storage unit 4 to the operation stop log data. Is stored in the log data storage unit 2.

Therefore, since the operation stop log data at the time of the above-mentioned abnormal stop can be stored in the log data storage unit 2, even if the operation stop log data is lost due to the abnormal stop of the monitoring device, Log data can be collected from the monitored device using the stored stop time to complement the log data, and the reliability of the monitoring function can be improved.

[0011]

FIG. 2 shows an embodiment of the present invention. In this figure, 20 is a monitoring device, and 22 is a logging function unit of the monitoring device 20. The logging function unit 22 includes a log data recording function unit 24 and a timer function unit 26. The log data recording function unit 24 stores the log data sequentially transmitted from the plurality of monitored devices 54 in the log data storage area (DASD) 28. The timer function unit 26 stores the time in the current time storage area 30 as the current time at regular intervals. This current time storage area 30
Is used by the log data recording function unit 24 to complement the operation stop log data. Further, the log data recording function unit 24 includes an operation start / stop unit 58 similar to the conventional one.
Are connected.

In FIG. 2, the log data storage area 28
1 corresponds to the log data storage unit 2 in FIG. 1, and the current time storage area 30 corresponds to the current time storage unit 4 in FIG. The timer function unit 26 corresponds to the time storage unit 6 in FIG. 1, and the log data recording function unit 24 corresponds to the log data storage control unit 8 in FIG.

The operation of the device of the present invention having this structure will be described below. For convenience of explanation, it is assumed that the monitoring operation of the monitoring device 20 is started and the log data transmitted from the monitored device 54 is continuously stored in the log data storage area 28 by the log data recording function unit 24. Further, the timer function unit 26 is assumed to continue to store the current time in the current time storage area 30 in a constant cycle.

If an abnormality occurs in the power supply of the monitoring device 20 during such logging and the operation of the logging function unit 22 is stopped, the operation is not stopped by the operation start / stop unit, so the log data storage area The operation stop log data is not stored in 28. Further, the operation of the monitoring device 20 is stopped without collecting the log data in the log data storage area 28 thereafter. However, the time at the end of the fixed period measured by the timer function unit 26 before the occurrence of the power supply abnormality is stored in the current time storage area 30.

After the operation of the monitoring device 20 is stopped, the power is restored and the log data recording function unit 24 starts to operate in response to the operation start operation of the operation start / stop unit 58 by the operator. At the start, the log data recording function unit 24
First, the log data in the final log data storage area stored in the log data storage area 28 is referenced to determine whether or not the log data is operation stop log data (see S1 in FIG. 3).

If the log data is the operation stop log data (refer to S1 in FIG. 3), the operation start log data is immediately stored in the log data storage area 28 (see S2 in FIG. 3). Is not the operation stop log data (see NO in S1 of FIG. 3), the current time storage area 30 is referred to read the last stored current time, and this is used as the operation stop log data in the log data storage area. 28 (see S3 in FIG. 3). The operation stop log data includes the current time and the device name of the monitoring target. As a result, similar to the case of normal termination described later, the operation stop log data of the log data collected for the monitored device 54, that is, the data indicating when the operation is stopped is stored in the log data storage area 28. You can do it. Therefore, depending on the time interval at which the log data is transmitted from the monitored device 54, the shorter the time interval of the timer interruption by the timer function unit 26, the greater the usefulness as the operation stop log data. After that, the process of storing the operation start log data in the log data storage area 28 is started (see S2 in FIG. 3).

When the log data is received, when the reception waiting is released, that is, when a timer interrupt occurs (see affirmative in S4 of FIG. 3), the current time is stored in the current time storage area 3
It is stored in 0 (see S5 in FIG. 3). If the data reception waiting is not released (see negative in S4 of FIG. 3), if the received log data is log data from the monitored device 54 (see negative in S6 of FIG. 3), the reception process, that is, Storage processing in the log data storage area 28 is performed (see S7 in FIG. 3).

If the received log data is an operation stop request from the operation start / stop unit 58 (see affirmative in S6 of FIG. 3), the operation stop log data at that time is stored in the log data storage area 28. (See S8 in FIG. 3), the process ends normally (see S9 in FIG. 3).

In the above embodiment, the case where the current time is stored in a fixed cycle has been described, but it is not always necessary to store it in a fixed cycle. Also, there is no need for a plurality of monitored devices.

[0020]

As described above, according to the present invention, the log data is collected from the monitored device and the current time is recorded at a constant cycle so that the current time is restored when the abnormally stopped monitoring device is restored. Since the time is stored in the log data storage device as the operation stop log data and the operation stop log data is complemented, it is useful for improving the reliability as the monitoring device.
