(1) Description of Network Resource Monitoring System According to Invention of Claim 1 FIG. 1 is a diagram showing a configuration of a network resource monitoring system when an embodiment of the present invention is applied, where 1 is a monitored device, Reference numeral 2 is a monitoring device, 3 is a communication path, 4 is a failure monitoring unit, 5 is a communication processing unit, 6 is a failure monitoring information display unit, 7 is a failure monitoring information processing unit, and 8 is another monitored device. In the network resource monitoring method according to the present embodiment, the monitored device 1 registers the monitored device 8 that notifies the monitoring device 2 of a failure of the monitored device 1 at the start of monitoring. This registration only needs to register the machine name. The monitored device 1 notifies the monitoring device 2 of all the failures that have occurred. The monitoring device 2, which has received the failure notification from the certain monitored device 1, notifies the other monitored device 8 registered in advance at the start of the monitoring of the monitored device 1 of the failure.

Further, when the failure monitoring information processing unit 7 determines that the failure information needs to be notified to another monitored terminal 8 as well, the failure information is transmitted from the communication processing unit 5 of the monitoring device 2 to another monitoring target. It is transmitted to the communication path 3 to the monitoring device 8. In the conventional system, the failure notification of a certain monitored apparatus 1 is sent only to the monitoring apparatus 2 or the machine of the network management center (for example, the failure status reporting method of Japanese Patent Laid-Open No. 63-280537), so the administrator fails. It became possible for general users to recognize it only after recognizing and making an announcement. Therefore, it takes time for a general user to recognize the failure. Therefore, as in this embodiment, when the failure information of a certain monitored device 1 is notified to another monitored device 8, the certain monitored device 1 executing the program normally operates like a batch processing device. Is an unmanned device and is effective when the program is executed with the authority of a general user from another monitored device 8.

Next, the operation will be described. Monitored device 1
When a failure occurs in, the failure monitoring unit 4 of the monitored device 1 detects it and passes the failure information to the communication processing unit 5. The failure information transmitted from the monitored device 1 is received by the communication processing unit 5 of the monitoring device 2 via the communication path 3. The fault information received by the communication processing unit 5 is processed by the fault monitoring information processing unit 7 together with the fault information formulating unit 10 to formulate the display contents. For example, when there is a line delimiter "/" as shown in FIG.
Display a blank line. If there is an "@",
Replace "@" with a line feed symbol and display. When the processes in the fault monitoring information processing unit 7 and the fault information formulation unit 10 are completed, the formulated fault information is passed to the fault monitoring information display unit 6 and displayed. In the above example, the case of line delimiters and line feed symbols was explained, but when formulating the display contents, for example, in addition to enlarged characters, emphasized characters,
Formulations such as underline, reverse display, digit alignment display, tabular display, display within ruled lines, or graphed display can be considered.

Figure 7
FIG. 3 is a diagram showing an example of a failure message transmitted from the monitored device 1 to the monitoring device 2. In this embodiment, fields of "fault message ID" and "control code" are added to the fault message. The fault message management unit 11 of the monitored device 1 assigns a fault message ID to each fault message. The fault message management unit 11 of the monitored device 1 sets the control code of the fault message. If the failure information is new, "addition" is set, if the failure status changes, "change" is set, and if the failure is restored and there is no need to display it, "delete" is set. The fault message management unit 11 of the monitoring device 2 processes the fault message of the "fault message ID" according to the "control code" of the received fault message.

FIG. 9 is a diagram showing an example of a failure message transmitted from the monitored device 1 to the monitoring device 2. The failure data of the failure message is composed of “monitoring target”, “failure date and time”, and “text data”. In the failure notification determination unit 12 of the monitored device 1,
The "fault message" received from the fault monitoring unit 4 is analyzed, and if the values of all fields other than the "fault date and time" are equal, the notification is withheld. Fault monitoring unit 4
Monitors each monitoring target at regular intervals,
There was a problem that once a failure was detected, the same failure message was reported at regular intervals, but this mechanism makes it possible to prevent it.

Next, the operation will be described. Monitored device 1
When a failure occurs in, the failure monitoring unit 4 of the monitored device 1 detects it and passes the failure information to the failure notification determination unit 12. The fault monitoring unit 4 of the monitored device 1 monitors each monitoring target at regular intervals. Therefore, the same failure information is passed to the failure notification determination unit 12 at regular intervals unless the failure is cleared. The fault report judging unit 12 judges the importance of the passed fault information, and if it is necessary to make a report, the communication processing unit 5
Pass to. Since the same failure information is input at regular intervals in the failure notification determination unit 12, if the fields other than the failure date and time are the same, it is judged that it is not worth notifying the monitoring device and the notification is withheld. If the fields other than the failure date and time are different, it is determined that the failure data is new and the failure information is transmitted to the monitoring device. Monitored device 1
The failure information transmitted from the monitoring device 2 via the communication path 3
Is received by the communication processing unit 5. After the failure information received by the communication processing unit 5 is processed by the failure monitoring information processing unit 7,
It is passed to and displayed on the fault monitoring information display unit 6. In the above-mentioned example, when only the failure date and time are different, the case where the failure information is not transmitted to the monitoring device has been described, but if there is a non-important reference level field other than the failure date and time, the unimportant field Even if the values are different, the monitoring device may not be notified.

FIG. 11 is a diagram showing an example of data conversion performed by the data format conversion unit 14. The data format conversion unit 14 of the monitored device 1 converts the numerical field in each field of the failure message into a network order so that the message does not depend only on a specific computer. The fault message is packetized in units of the minimum packet size of the network layer of the currently supported communication protocol. The minimum value of the packet size of the network layer is managed by the general-purpose gateway unit 13 of the monitoring device 2. After receiving the failure message, the general-purpose gateway unit 13 of the monitoring device 2 assembles the packet, converts the numerical value from the network order to the order of the own computer, and passes it to the failure monitoring information processing unit 7.

Next, the operation will be described. Monitored device 1
When a failure occurs in, the failure monitoring unit 4 of the monitored device 1 detects it and passes the failure information to the data format conversion unit 14. The data format conversion unit 14 converts the failure information into a format that does not depend on the communication protocol, and passes it to the communication processing unit 5. The failure information transmitted from the monitored device 1 is received by the communication processing unit 5 of the monitoring device 2 via the communication path 3. Data exchange between the communication processing unit 5 of the monitored device 1 and the communication processing unit 5 of the monitoring device 2 is performed by adjusting the size of the communication packet to the minimum packet size of the currently supported communication protocols. The upper layers are being shared. The fault information received by the communication processing unit 5 is converted by the general-purpose gateway unit 13 into a data format opposite to that shown in FIG. 11, and then passed to the fault monitoring information processing unit 7. The fault information is processed by the fault monitoring information processing unit 7, and then passed to the fault monitoring information display unit 6 for display.
