Abstract

PROBLEM TO BE SOLVED: To solve the problem that a conventional monitor system can not inform a remote administrator that a monitor device itself gets out of order and can not be operated in such a case. SOLUTION: This system is equipped with a log collecting and transmitting device 4 which receives log data from the monitor device 1 monitoring a monitored device 2 to detect a fault occurring to the monitor device 1 from the received log data and also e-mails the fault of the monitor device 1 to the remote administrator 3; and the remote administrator 3 e-mails a signal instructing resetting to the log collecting and transmitting device 4. Thus, the signal instructing the resetting is transmitted to the monitor device 1, which restarts itself.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiment 1 Hereinafter, a first embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a configuration diagram showing a monitoring system according to Embodiment 1 of the present invention. In FIG. 1, 1 is a monitoring device, 2 is a monitored device monitored by the monitoring device 1, and a plurality of monitored devices are connected to the monitoring device 1. Reference numeral 3 denotes a remote manager who receives a notification from the monitoring device 1. Reference numeral 4 denotes a log collection and transmission device, which is configured to always output failure information or log data from the monitoring device 1 and periodically notify the remote administrator 3 by e-mail. Further, when the monitoring device 1 fails, the log collection and transmission device 4 detects that log data is not transmitted, and also notifies the remote manager 3 at this time.

Hereinafter, the monitoring device 1 and the log collection / transmission device 4
Will be described. The monitoring device 1 includes a monitoring processing unit 1
1, a log output unit 13 that outputs log data to the log collection and transmission device 4, a program storage unit 14 that stores a monitoring program, and a reset input unit 15 that receives a reset signal. The log collection and transmission device 4 collects log data output from the monitoring device 1.
1, a mail transmitting unit 42 for transmitting an e-mail to the remote manager 3, a mail receiving unit 43 for receiving the e-mail sent from the remote manager 3, and a mail analyzing unit 44 for analyzing the received e-mail. , A program transmission unit 45 that transmits the updated program to the monitoring device 1, and a reset output unit 46 that outputs a reset signal to the monitoring device 1.

Next, the operation will be described. The log collection and transmission device 4 monitors the log data transmitted from the monitoring device 1, and when the log data is no longer transmitted from the monitoring device 1, the log collection unit 41 of the log collection and transmission device 4 detects this. , To the mail transmission unit 42. Email sending unit 42
Sends an e-mail to the remote manager 3 immediately indicating that a failure has occurred in the monitoring device 1 and has hung up. When the remote manager 3 receives the mail and transmits a response mail, the mail receiving unit 43 of the log collection and transmission device 4 receives the mail and sends it to the mail analyzing unit 44. When recognizing that the received mail is a mail for instructing restart, the mail analysis unit 44 issues a reset signal output instruction to the reset output unit 46. By this reset signal output instruction,
The reset output unit 46 sends a reset signal to the reset input unit 15 of the monitoring device 1. Thus, the reset input unit 15 restarts the monitoring program stored in the program storage unit 14 of the monitoring device 1, so that the monitoring device 1 is restored and operates.

The monitoring program in the program storage unit 14 can be updated by sending it from the remote manager 3 via the log collection and transmission unit 4 by e-mail at irregular intervals. Specifically, first, the mail to which the program is attached is received by the mail receiving unit 43 and sent to the mail analyzing unit 44. When recognizing that the received mail is a mail for instructing the update of the program, the mail analysis unit 44 issues a program transmission instruction to the program transmission unit 45. In response to the program transmission instruction, the program transmission unit 45 transmits the program to the program storage unit 14 of the monitoring device 1.
Thereby, the program storage unit 14 updates and stores the program. Thereafter, when the program storage unit 14 sends a reset signal to the reset input unit 15, the monitoring device 1 starts up with the updated program.

According to the first embodiment, even when a failure has occurred in the monitoring device 1 itself and the monitoring device 1 has become inoperable, the details of the failure are notified to the remote manager 3, thereby enabling the monitoring device 1 to operate in a short time. Since it can be restarted from a remote place, it is possible to respond immediately in an emergency, thereby increasing the operating rate of the system and reducing maintenance costs.

Embodiment 2 FIG. In the second embodiment, the monitoring program in the program storage unit 14
It does not have a function of sending the electronic mail via the log collection and transmission device 4 irregularly. Other functions are the same as those of the first embodiment.

FIG. 2 is a configuration diagram showing a monitoring system according to a second embodiment of the present invention. In FIG.
Reference numerals 4, 11 to 15, 41 to 44 and 46 are the same as those in FIG. In the second embodiment, the remote manager 3 is notified by e-mail, and the remote manager 3 instructs a reset. Thus, even when a failure occurs in the monitoring device 1, the remote administrator 3 can reset the monitoring device 1 and restart the monitoring device 1.

According to the second embodiment, the log collection / transmission device 4 detects a failure in the monitoring device 1 and notifies the remote administrator 3 by e-mail, and sends the response message from the remote administrator 3 to the monitoring device. 1 can be restarted.

Embodiment 3 In the third embodiment, the remote manager 3 receives an e-mail indicating that a failure has occurred in the monitoring device 1 and transmits a response mail, whereby the monitoring device 1
The function that restarts is lost. Other functions are the same as those of the second embodiment.

FIG. 3 is a configuration diagram showing a monitoring system according to a third embodiment of the present invention. In FIG.
4, 11, 15, 41 and 42 are the same as those in FIG. The third embodiment has a configuration in which the log collection and transmission device 4 that has detected a failure in the monitoring device 1 notifies the remote administrator 3 by e-mail. Thereby, the remote manager 3 can know the failure of the monitoring device 1 and can take appropriate measures.

According to the third embodiment, the failure of the monitoring device 1 can be detected by the log collection and transmission device 4 and notified to the remote manager 3 by e-mail. Can be encouraged.

[0020]

Since the present invention is configured as described above, it has the following effects. A monitoring device that monitors the monitored device, receives log data from the monitoring device, detects a failure of the monitoring device based on the reception status of the log data, and notifies the remote administrator of the monitoring device failure by e-mail. With a log collection and transmission device,
The remote manager can know the failure of the monitoring device and can take appropriate measures.

When the log collection and transmission device receives a response mail from the remote administrator instructing the restart of the monitoring device, it instructs the monitoring device to restart. And an instruction to restart the monitoring device can be given by a response mail.

When the monitoring device receives a restart instruction from the log collection / transmission device, the monitoring device restarts itself, so that the monitoring device can be restarted by an instruction from the remote manager. Furthermore, since the monitoring device has a program storage unit that stores a monitoring program used for restarting, the monitoring device can be restarted using this monitoring program.

Further, the monitoring program stored in the program storage is updated based on the e-mail transmitted from the remote manager, so that the monitoring program can be updated from a remote place. Further, the monitoring device is configured to restart itself when the monitoring program is updated, so that the monitored device can be monitored by the updated monitoring program.
