Abstract

The network management system includes the electronic message generating unit that generates an electronic message from a status of a monitored unit which may generate a trouble; and the arranging unit that analyzes the contents of the electronic message generated by the electronic message generating unit, determines a seriousness level of the trouble, determines a destination of an electronic message according to the seriousness level and a time and date of an occurrence, adds causes and/or countermeasures of the trouble to the electronic message, and transmits the electronic message to the destination.

Claims

1. A network management system comprising:

an electronic message generating unit that generates an electronic message indicating a status of a monitored unit that may generate a trouble in a network or based on a message transmitted from the monitored unit; and

an arranging unit that collects data for analyzing the trouble and analyzes the collected data,

wherein the arranging unit analyzes the contents of an electronic message generated by the electronic message generating unit, determines a seriousness level of the trouble, and determines a destination of the electronic message according to the seriousness level and a date and time of the occurrence.

2. The network management system according to claim 1, wherein the arranging unit adds any one or both of causes and countermeasures of the trouble to the electronic message, and transmits the electronic message to the message destination.

3. The network management system according to claim 1, wherein said electronic message generating unit monitors the status of said monitored unit, creates the second electronic message immediately after detecting a trouble, and transmits the second electronic message to said arranging unit in the form of an electronic mail.

4. The network management system according to claim 1, wherein said electronic message generating unit has a function of making said monitored unit execute a command according to a request from a remote place, thereby to understand or detect a status of said monitored unit.

5. The network management system according to claim 1, wherein said arranging unit has a function of presenting a result of an analysis carried out based on the collected data, to an operator or other relevant persons.

6. The network management system according to claim 1, wherein said arranging unit has a database that contains information about a connection relationship between said monitored unit and said electronic message generating unit.

7. A network management system comprising:

an electronic message generating unit that generates an electronic message indicating a status of a monitored unit that may generate a trouble in a network or based on a message transmitted from the monitored unit; and

an arranging unit that collects data for analyzing the trouble and analyzes the collected data,

wherein the electronic message generating unit has a communication unit that is connected to one or both of a network to which the monitored unit is connected and a network that is used for monitoring.

8. The network management system according to claim 7, wherein the electronic message generating unit has a transmission unit which transmits an operation command to the monitored unit.

9. The network management system according to claim 7, wherein the arranging unit analyzes a status of an electronic message generated by the electronic message generating unit, and determines a message destination according to a result of the analysis.

10. The network management system according to claim 7, wherein said electronic message generating unit monitors the status of said monitored unit, creates the second electronic message immediately after detecting a trouble, and transmits the second electronic message to said arranging unit in the form of an electronic mail.

11. The network management system according to claim 7, wherein said electronic message generating unit has a function of making said monitored unit execute a command according to a request from a remote place, thereby to understand or detect a status of said monitored unit.

12. The network management system according to claim 7, wherein said arranging unit has a function of presenting a result of an analysis carried out based on the collected data, to an operator or other relevant persons.

13. The network management system according to claim 7, wherein said arranging unit has a database that contains information about a connection relationship between said monitored unit and said electronic message generating unit.

15. The arranging unit according to claim 14, wherein the arranging unit further has a display screen which displays for reading the contents of any one or both of the historical record database regarding the monitored unit and knowledge database.

16. The arranging unit according to claim 14, wherein said monitored unit posts the electronic message in the form of an electronic mail, and said arranging unit further comprising:

a message searching unit which searches the knowledge database, thereby determining a seriousness level, possible causes and countermeasures, and an accompanying analysis rule of a trouble respectively, based on the content of the electronic mail from said monitored unit;

an arrangement destination determining unit which determines an arrangement destination of a work by searching the arrangement database, based on the seriousness level determined by said message searching unit, and the current time;

an analysis rule executing unit which executes the trouble analysis rule determined by said message searching unit, collects data necessary for the analysis of the trouble and/or estimating a cause; and

an electronic mail creating unit which creates an electronic mail to be posted to the arrangement destination, based on information from said message searching unit, arrangement destination determining unit, and analysis rule executing unit.

14. An arranging unit comprising at least one from a group consisting of:

a knowledge database for storing a cause, a countermeasure method, and a trouble analysis rule corresponding to the contents of a message of a trouble or an alarm informed from a monitored unit that may generate a trouble in a network;

a historical record database for storing a historical record of messages generated in the past from the monitored unit; and

an arrangement database recorded with a plurality of message destinations that are different depending on an occurrence time of the trouble or an alarm and the contents of the message.

17. A network management method comprising:

monitoring a status of a monitored unit that can fix generate a trouble in a network;

generating a first electronic message based on the monitored status of said monitored unit;

determining a seriousness level of the trouble by analyzing the contents of the first electronic message;

determining a destination of a second electronic message for informing about the trouble based on the determined seriousness level, time and date of occurrence of the trouble;

determining causes and/or countermeasures of the trouble;

creating the third electronic message that contains information that trouble has occurred, causes and/or countermeasures of the trouble; and

transmitting the third electronic message to the determined destination.

18. A computer readable medium for storing instructions, which when executed on a computer, causes the computer to perform the steps of:

monitoring a status of a monitored unit that can generate a trouble in a network;

generating a first electronic message based on the monitored status of said monitored unit;

determining a seriousness level of the trouble by analyzing the contents of the first electronic message;

determining a destination of a second electronic message for informing about the trouble based on the determined seriousness level, time and date of occurrence of the trouble;

determining causes and/or countermeasures of the trouble;

creating the third electronic message that contains information that trouble has occurred, causes and/or countermeasures of the trouble; and

transmitting the third electronic message to the determined destination.
