Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a UNIX system resource monitoring method, and more particularly to a UN in a computer system that manages file resources (hereinafter simply referred to as resources) by using the QUIOTA subsystem of the UNIX system.
The present invention relates to an IX system resource monitoring system.

[0002]

2. Description of the Related Art In a UNIX system, a file can be easily created and deleted, so that the user can use the file without being aware of it. However, in a large-scale computer system, many users share resources with each other and perform processing, so resource management is necessary.

Conventionally, the UNIX system uses the QUOTA subsystem, which is a subsystem, to give each user a file and disk block usage limit, and when this limit is exceeded, a message is sent to the user. , A command or the like was used to display the usage status of the resource of a specific user to the system administrator who manages the operation of the computer system.

[0004]

DISCLOSURE OF THE INVENTION The above-mentioned conventional UNI
In the resource management method of the X system, when the usage of the resource by the user exceeds the resource usage limit amount, the user is notified only by a message. Only the user can immediately recognize that the usage limit has been exceeded, the system administrator can only recognize it for the first time with a command, etc. It takes a lot of time to organize the resource usage information of the computer system such as whether files or disk blocks are gone, and it is difficult for the system administrator to predict the resource usage of the user in advance.

When the user has not used the computer system for a long time, the resource management information is stored in order to know the resource management information such as the current resource usage amount and resource usage limit amount of the user. There was a disadvantage that you had to search for files.

[0006] In view of the above points, an object of the present invention is UNI.
In a large-scale center-operated computer system that uses the QUOTA subsystem, which is the resource management system for the X system, provides resource usage information and resource management information to the system administrator in order to accurately determine the resource usage status. It is an object of the present invention to provide a UNIX system resource monitoring method capable of assisting a system administrator in efficiently and smoothly managing and operating resources.

[0007]

According to the UNIX system resource monitoring method of the present invention, center operation is performed using a large-scale computer system using the UNIX system and having a sufficient disk capacity, and the QU of the UNIX system is used.
In a computer system in which the system administrator manages the user's file resources using the OTA subsystem, the disk block usage for each user, the soft and hard limits of the disk block usage, the number of files held, and the number of files Includes the QUOTA file that holds the resource management information consisting of the soft limit and hard limit of the number of possessions, the date when each user used the computer system, the user ID on the computer system given to the user, and the user A date data file that holds date data consisting of the group ID on the computer system, the amount of disk block used by the user, and the number of files held by the user, and date data created for each specified period Date data file Date data creating means for storing, resource usage information editing means for editing and outputting resource usage information using date data of the date data file according to a command from the system administrator, and a command from the system administrator. Accordingly, when the resource management information of the QUOTA file and the date data of the date data file are used to output the information of the user who has exceeded the resource use limit to the administrator terminal or when the user logs in to the UNIX system. And a control message output means for outputting the resource management information of the user as a message from the QUOTA file to the user terminal.

[0008]

In the UNIX system resource monitoring system of the present invention,
The QUAOTA file holds the resource management information consisting of the disk block usage for each user, the soft limit and hard limit of the disk block usage, the number of files held, the soft limit and the hard limit of the number of files held, and the date data file stores each The date when the user used the computer system, the user ID on the computer system given to the user, the group ID on the computer system including the user, the disk block usage amount used by the user, and the user's possession The date data consisting of the number of files stored is stored, the date data creation means creates the date data for each specified period and stores it in the date data file, and the resource usage information editing means responds to the command from the system administrator. Date data file The resource usage information is edited and output by using, and the control message output means exceeds the resource usage limit by using the resource management information in the QUOTA file and the date data in the date data file in response to a command from the system administrator. The user information that has been lost is output to the administrator terminal, or the resource management information of the user is output as a message from the QUOTA file to the user terminal when the user logs in to the UNIX system.

[0009]

The present invention will be described in detail with reference to the drawings.

FIG. 1 shows a UNIX according to an embodiment of the present invention.
It is a block diagram which shows the structure of a system resource monitoring system.
The UNIX system resource monitoring method of this embodiment is UNIX.
A UNIX system operation management unit F-1 for managing the execution state and operation of the computer system in the system;
A file management unit F-2 that manages files by performing processing related to files of the UNIX system, and a subsystem QUOTA that manages resources of the UNIX system.
Subsystem unit F-3 and QUOTA subsystem unit F
A QUOTA file D-1 in which resource management information such as resource usage amount and resource usage limit amount (soft limit and hard limit) for each user, which is managed by -3, is recorded,
A date data file D-2 in which date data including user's disk block usage amount, file possession number, etc. is recorded every designated fixed period (for example, one day), and a printer device P for outputting resource usage information etc. -1, a terminal device T-1 used by a user or a system administrator, a date data creating means S-1 for creating date data, and a resource usage information editing means S for editing resource usage information from the date data.
-2 and control message output means S-3 for outputting resource management information and resource usage information and a message to the terminal device T-1 used by the user or system administrator.

Referring to FIG. 2, the date data file D
The date data format of -2 was used by each user, the date when each user used the computer system, the user ID on the computer system given to the user, the group ID on the computer system including the user, and the user. It consists of the disk block usage and the number of files owned by the user.

Next, the U of the present embodiment constructed as described above is used.
The operation of the NIX system resource monitoring system will be described.

Now, for example, it is assumed that a user with user ID 74 issues a file creation request. The file size is X blocks, and the current QUAOTA file D-1
Of the user ID No. 74 is b, the soft limit of the disk block usage is b ', the hard limit of the disk block usage is b ", the number of owned files is i, and the soft limit of the number of owned files is i'. , And the hard limit of the number of files held is i ″.

When an instruction to create a file is issued from the UNIX system operation management unit F-1, the file management unit F-2
Will handle this and actually try to create a file of X blocks.

At this time, the QUOTA subsystem unit F-
3 is a disk block usage amount b of the user ID No. 74 from the QUAOTA file D-1, a soft limit b ′ of the disk block usage amount, a hard limit b ″ of the disk block usage amount, a file holding number i, and a file holding number software The limit i ′ and the hard limit i ″ of the number of held files are read, and it is determined whether the user with the user ID 74 can create a file.

First, the QUOTA subsystem section F-3
Checks the file holding number i.

When the number i of files held exceeds the soft limit i '(i' = <1 + i), the QUOTA subsystem unit F-3 sends a warning message to the user via the control message output means S-3. Terminal device T-1 used by
To display.

When the number i of files held exceeds the hard limit i "(i" = <1 + i), QUOTA
The subsystem unit F-3 displays the warning message on the terminal device T-1 used by the user via the control message output unit S-3, and causes the file management unit F-2 to interrupt the file creation process.

Now, it is assumed that the file creation process performed by the user ID No. 74 does not exceed the soft limit i'of the file holding number i.

Next, the QUOTA subsystem section F-3
Examines the disk block usage b as in the case of the file holding number i.

When the disk block usage amount b exceeds the soft limit b '(b' = <X + b), QUOT
The A subsystem part F-3 displays the warning message on the terminal device T-1 used by the user via the control message output means S-3.

When the disk block usage amount b exceeds the hard limit b ″ (b ″ = <X + b), Q
The UOTA subsystem part F-3 displays a warning message on the terminal device T-1 used by the user via the control message output means S-3, and causes the file management part F-2 to interrupt the file creation process. ..

Now, it is assumed that the disk block usage amount b has not exceeded the hard limit b ″ in the file creation process performed by the user ID No. 74.

When a file is created by the file management unit F-2, the QUOTA subsystem unit F-3 sends a QU
In addition to updating the file holding number i and the disk block usage amount b of the user ID No. 74 of the OTA file D-1, the date of the file creation processing and the user ID (74
No.), the group ID, the current disk block usage (X), and the number of files held (1) are notified to the date data creating means S-1.

The date data creating means S-1 uses the date, the user ID (No. 74), the group ID, the current disk block usage (X) and the number of files held (1) as the date data, and the date data file D- Record in 2.

The date data creating means S-1 is provided with a command immediately after the UNIX system is operated by the system administrator for a designated period (for example, 2 days immediately after the operation,
Disk block usage from 2 days to 3 days)
The number of files held is recorded in the memory, and when the designated period ends, date data is created and stored in the date data file D-2. During the designated time period, the date data creating means S-1 adds the disk block usage amount, the file holding number, etc. to the same record, and when the time period elapses, the disk block usage amount, the file holding number, etc. are written in another record To collect. For this reason, date data is created at regular intervals after the UNIX system is operated, and a plurality of date data for the same user is created.

The date data created by the date data creating means S-1 and stored in the date data file D-2 is
When the system administrator inputs commands, U
In response to the notification from the NIX system operation management unit F-1, it is edited as resource use information by the resource use information editing means S-2 and output to the printer device P-1 or the terminal device T-1 used by the system administrator.

When the date data of the date data file D-2 is edited using the user ID as a search index, the resource usage information output by the resource usage information editing means S-2 is the disk block usage amount of the specific user, It is a user usage record that aggregates the number of files held. When the date data of the date data file D-2 is edited using the date and the user ID as the search index, the resource use information output by the resource use information editing means S-2 is divided into certain sections such as week, month or year. The user usage record is a tabulation of the total amount of disk block usage and the number of files owned by the user for different periods.

In addition to this, when the system administrator inputs a command or the like, the resource use limit amount is already exceeded by using the resource management information of the QUOTA file D-2 and the date data of the date data file D-3. The resource use information and resource management information of the user can be edited and output to the terminal device T-1 or the printer device P-1 used by the administrator.

As described above, by providing the resource use information, the resource management information and the like to the system administrator, the system administrator can easily confirm various information, and refer to these information to check the resource information. It is possible to determine the resource usage limit amount for each user so that management and operation can be performed efficiently and smoothly, and to set the user resource usage limit amount by a command or the like using the QUOTA subsystem.

The user with the user ID 74 is the UNI
When logging in to the X system, the control message output means S-3 displays the user ID from the QUAOTA file D-1.
The resource management information No. 74 is read and the resource management information of the user is output to the terminal device T-1 used by the user. The resource management information that is output is the ratio (b / b ", i / to the hard limit (b", i ") of the disk block usage amount b, the file holding number i, the disk block usage amount b, and the file holding number i. i ″) and the like are possible.

In the description of the operation of the above embodiment, the case where the user makes a file creation request has been mainly described, but the same applies to the case where a file update request, a deletion request, etc. are made. Needless to say, resources are monitored.

[0033]

As described above, the present invention is suitable for UNIX.
In a large-scale center-operated computer system that uses the QUOTA subsystem, which is the system resource management system, provides the system administrator with resource usage information to accurately determine the resource usage status. In order to efficiently and smoothly manage and operate the resources of the above, there is an effect that it becomes possible for the system administrator to assist the user in determining the resource usage limit amount.

Also, when the user logs in to the UNIX system, by presenting resource management information such as the user's current resource usage amount and resource usage limit amount to the user, it is possible to prevent the trouble of the user. You can expect an effect.
