Embodiment 1 FIG.
FIG. 1 shows a configuration example of an electronic mail communication system according to this embodiment.

In FIG. 1, a device 200 is, for example, a server device, a network device such as a switch or a router, a UPS (Uninterruptable Power Supply), or the like.
The device 200 includes a monitoring agent that detects the occurrence of a failure, and the monitoring agent transmits a failure notification mail 600 that is an e-mail notifying the occurrence of the failure.
In the following description, it is described that the failure notification mail 600 is transmitted from the device 200, which means that the device 200 transmits the failure notification mail 600 generated by the monitoring agent in the device 200.
The device 200 in which a failure has occurred is referred to as a failure-occurring device 200.

The electronic mail relay device 100 receives the failure notification mail 600 from the failure occurrence device 200 and transmits the received failure notification mail 600 to the mail provider device 300.
The failure occurrence device 200 generally transmits many failure notification emails 600 with duplicate contents in a short time.
When the reception frequency of the failure notification mail 600 from the failure occurrence device 200 exceeds the threshold, the electronic mail relay apparatus 100 integrates a plurality of failure notification emails 600 transmitted from the failure occurrence device 200 to obtain a plurality of failure notifications. One e-mail including the contents of the e-mail 600 is generated as an integrated e-mail.
Then, the e-mail relay apparatus 100 transmits the integrated e-mail to the mail provider apparatus 300.
In the following, integrated email is also referred to as integrated email.

The integrated electronic mail that has reached the mail provider apparatus 300 is transmitted from the mail provider apparatus 300 to the mail recipient terminal apparatus 500 via the Internet 400.
For this reason, even if the failure notification mail 600 is frequently transmitted from the failure-occurring device 200, the electronic mail relay device 100 and subsequent devices transmit one integrated email instead of many failure notification emails 600. There is no pressure on the band.
In addition, since the mail receiver terminal device 500 receives only the integrated electronic mail, even if the failure notification mail 600 is frequently transmitted from the failure occurrence device 200, the mail receiver confirms a number of failure notification mails 600. This does not affect the work efficiency of the mail recipient.
Further, since the integrated e-mail includes the content of the failure notification mail 600 from the failure occurrence device 200, the information provided to the mail recipient does not change.

FIG. 2 shows a configuration example of the electronic mail relay device 100 according to the present embodiment.
2 shows the minimum configuration for explaining the operation of the electronic mail relay apparatus 100 according to the present embodiment, and other elements may be added to the configuration of FIG.

In FIG. 2, the e-mail receiving unit 101 receives an e-mail from the device 200.
The e-mail receiving unit 101 can determine whether the received e-mail is a failure notification mail 600 from the failure occurrence device 200 or a normal time e-mail from the device 200 in which no failure has occurred.
For example, the e-mail receiving unit 101 can determine whether the e-mail is a failure notification e-mail 600 or a normal e-mail with reference to a specific flag in the header data of the received e-mail.
When the received e-mail is a normal e-mail, the e-mail receiving unit 101 outputs a normal e-mail to the e-mail transmitting unit 105, and sends the normal e-mail from the e-mail transmitting unit 105. The data is transmitted to the provider device 300.
On the other hand, when the received e-mail is the failure notification mail 600, the e-mail receiving unit 101 outputs the received failure notification mail 600 to the e-mail buffer unit 102.
In addition, the e-mail receiving unit 101 notifies the reception frequency measuring unit 103 that the failure notification mail 600 has been received.
When receiving the first failure notification mail 600 from the failure-occurring device 200, the e-mail receiving unit 101 instructs the reception frequency measuring unit 103 to start measuring the reception frequency.

The e-mail buffer unit 102 receives the failure notification mail 600 from the e-mail receiving unit 101 and stores the failure notification mail 600.
The e-mail buffer unit 102 stores the header data and payload data of the failure notification mail 600 together.
In addition, when two or more failure notification emails 600 are received from the same failure occurrence device 200, the email buffer unit 102 stores the failure notification emails 600 according to the reception order.
Further, when the failure notification mail 600 is received from two or more failure occurrence devices 200, a storage area is provided for each failure occurrence device 200, and the failure notification email 600 is stored for each failure occurrence device 200.

The reception frequency measurement unit 103 includes a timer and a reception frequency counter, and measures the reception frequency of the failure notification mail 600 from the failure occurrence device 200.
The time of the timer of the reception frequency measuring unit 103 is set to a time (for example, 5 minutes) in which the delay is not a problem in the mail recipient terminal device 500.
The reception frequency measurement unit 103 starts timer measurement when an instruction to start reception frequency measurement is given from the e-mail reception unit 101.
When the reception of the failure notification mail 600 is notified from the e-mail receiving unit 101, the reception number counter is incremented.
When two or more faulty devices 200 are instructed to start reception frequency measurement from the e-mail receiving unit 101, timer measurement is performed for each faulty device 200, and the faulty device 200 Every time the reception counter is incremented.

The integrated email generation unit 104 integrates two or more failure notification emails 600 from the failure occurrence device 200 stored in the email buffer unit 102 and includes the contents of two or more failure notification emails 600 1 One email as a unified email.
More specifically, the integrated email generation unit 104 is stored in the email buffer unit 102 when the reception frequency of the failure notification mail 600 measured by the reception frequency measurement unit 103 exceeds a predetermined threshold. Two or more failure notification mails 600 are integrated to generate an integrated electronic mail.
Then, the integrated email generation unit 104 outputs the generated integrated email to the email transmission unit 105.

  The e-mail transmission unit 105 receives a normal e-mail input from the e-mail reception unit 101, an integrated e-mail input from the integrated e-mail generation unit 104, and a failure notification e-mail 600 read from the e-mail buffer unit 102 as a mail provider device. To 300.

Next, an example of the operation of the electronic mail relay apparatus 100 according to the present embodiment will be described with reference to the flowcharts of FIGS.
FIG. 3 is a flowchart illustrating an operation example of the e-mail receiving unit 101.
FIG. 4 is a flowchart illustrating an operation example of the reception frequency measurement unit 103.
FIG. 5 is a flowchart illustrating an operation example of the integrated email generation unit 104.
FIG. 6 is a flowchart showing an operation example of the e-mail transmission unit 105.
For the sake of simplicity, the description of the processing when the e-mail receiving unit 101 receives a normal e-mail will be omitted below.
Similarly, an example in which the failure notification mail 600 is repeatedly received from one failure occurrence device 200 will be described below.
When receiving the failure notification mail 600 from two or more failure occurrence devices 200 in parallel, the procedure shown in FIGS. 3 to 6 may be performed for each failure occurrence device 200.

  First, an operation example of the e-mail receiving unit 101 will be described with reference to FIG.

When the failure notification mail 600 is received (S301), the e-mail receiving unit 101 outputs the received failure notification mail 600 to the e-mail buffer unit 102, and stores the failure notification mail 600 in the e-mail buffer unit 102. (S302).
Further, the e-mail receiving unit 101 notifies the reception frequency measuring unit 103 of the reception of the failure notification mail 600 (S303).
As described above, when receiving the first failure notification mail 600 from the failure occurrence device 200 or receiving the first failure notification mail 600 after the timer of the reception frequency measuring unit 103 times out, the electronic mail receiving unit 101 Instructs the reception frequency measurement unit 103 to start measurement of the reception frequency, whereby the reception frequency measurement unit 103 starts timer measurement.
Further, as described above, the e-mail receiving unit 101 can determine whether the e-mail is a failure notification e-mail 600 or a normal e-mail with reference to a specific flag in the header data of the received e-mail.

  Next, an operation example of the reception frequency measurement unit 103 will be described with reference to FIG.

The reception frequency measurement unit 103 increments the reception number counter every time the reception of the failure notification mail 600 is notified from the e-mail receiving unit 101 (YES in S402) until a timer timeout occurs (NO in S401). (S403).
On the other hand, when a timer timeout occurs (YES in S401), the reception frequency measuring unit 103 calculates the reception frequency (S404).
More specifically, the reception frequency measuring unit 103 receives the failure notification mail 600 per unit time (for example, 1 minute) based on the count value of the reception frequency counter and the time (for example, 5 minutes) measured by the timer. Is calculated.
Note that the reception frequency measuring unit 103 may treat the count value of the reception frequency counter as it is as the reception frequency.
When a timeout occurs, the reception frequency measuring unit 103 notifies the email receiving unit 101 of the occurrence of the timeout.
Accordingly, the e-mail receiving unit 101 can recognize that the next time the failure notification mail 600 is received from the failure-occurring device 200 is the timing for instructing the reception frequency measuring unit 103 to start measuring the reception frequency. .

If the calculated reception frequency exceeds a predetermined threshold (YES in S405), the reception frequency measurement unit 103 instructs the integrated email generation unit 104 and the email transmission unit 105 to transmit the integrated email ( S406).
On the other hand, when the calculated reception frequency is within the threshold (NO in S405), the reception frequency measurement unit 103 instructs the e-mail transmission unit 105 to transmit the normal failure notification mail 600 (S407).

Thereafter, the reception frequency measuring unit 103 clears the count value of the reception number counter to zero (S408).
Note that the count value of the reception number counter may be cleared to zero immediately after the time-out is determined in S401.
Thereafter, the reception frequency measurement unit 103 sets a timer if there is an instruction to start reception frequency measurement from the e-mail reception unit 101 (S409).

  Next, an example of the operation of the integrated email generation unit 104 will be described with reference to FIG.

The integrated e-mail generation unit 104 reads the failure notification e-mail 600 from the e-mail buffer unit 102 when there is an integrated e-mail transmission instruction from the reception frequency measurement unit 103 (YES in S501) (S502).
Next, the integrated email generation unit 104 integrates the read failure notification email 600 to generate an integrated email (S503).
For example, the integrated e-mail generating unit 104 generates an integrated e-mail in which payload data (title and text) in the failure notification e-mail 600 is described according to the receiving order of the e-mail receiving unit 101.
For example, when five failure notification emails 600 are read from the e-mail buffer unit 102, an integrated email that lists the payload data of the five failure notification emails 600 in the order of reception may be generated. Good.
If the payload data is duplicated in two or more failure notification emails 600, one of the failure notification emails 600 is selected for deduplication, and only the payload data of the selected failure notification emails 600 is selected. It may be included in the integrated mail.
Then, in order to notify the mail recipient of the presence of another failure notification mail 600 with duplicate payload data, the transmission time included in the header data of each failure notification mail 600 may be described in the integrated mail. Good.
Further, the integrated email generation unit 104 selects the failure notification email 600 having the same character string described in the title column from the failure notification emails 600 read from the email buffer unit 102, and selects the selected failure notification. An integrated mail may be generated from the mail 600.
Then, the integrated email generation unit 104 outputs the integrated email generated in S503 to the email transmission unit 105 (S504).

  Next, an operation example of the e-mail transmission unit 105 will be described with reference to FIG.

When the transmission instruction is input from the reception frequency measurement unit 103 (YES in S601), the e-mail transmission unit 105 determines whether the instruction from the reception frequency measurement unit 103 is a normal mail transmission instruction or an integrated mail transmission instruction. It is determined whether or not there is (S602).
In the case of a normal mail transmission instruction (YES in S602), the e-mail transmission unit 105 reads the failure notification mail 600 from the e-mail buffer unit 102 (S603), and reads each read failure notification mail 600 as an individual electronic mail. It transmits to the mail provider apparatus 300 as an email (S604).
On the other hand, if it is an instruction to send an integrated mail (NO in S602), the e-mail transmitting unit 105 inputs the integrated mail from the integrated e-mail generating unit 104 (S605), and the input integrated mail is sent to the mail provider device 300. Transmit (S606).

  As described above, the e-mail relay apparatus 100 according to the present embodiment generates one e-mail including the contents of two or more failure notification mails 600 transmitted from the failure occurrence device 200 as an integrated e-mail, Since the generated integrated electronic mail is transmitted, even when a large number of failure notification mails 600 are transmitted from the failure occurrence device 200, it is possible to reduce the influence on the communication band and the work efficiency of the recipient of the email. .

The e-mail receiving unit 101 may receive an e-mail instructing to suspend transmission of the failure notification e-mail 600 from the e-mail recipient terminal device 500 as a transmission suspension instruction e-mail.
When the e-mail receiving unit 101 receives the transmission suspension instruction e-mail, the e-mail transmitting unit 105 transmits the failure notification mail 600 from the failure occurrence device 200 including the integrated e-mail for a predetermined period. Stop.
In other words, even when the e-mail receiving unit 101 continuously receives the failure notification mail 600 from the failure occurrence device 200, the electronic mail receiving unit 101 only stores the failure notification mail 600 in the e-mail buffer unit 102. It is not transmitted from the mail transmission unit 105.

Further, the electronic mail relay device 100 may encrypt and transmit the failure notification mail 600 or the integrated mail.
If the mail recipient terminal device 500 is a mobile phone or the like, the e-mail relay device 100 converts the format so that the failure notification mail 600 or the integrated mail from the failure occurrence device 200 can be easily viewed on the mobile phone. The contents may be summarized.
Further, if a failure occurs in the device 200 at midnight, the e-mail relay apparatus 100 does not immediately transmit the failure notification mail 600 or the integrated mail, but fails in a time zone that an operator can handle. The notification mail 600 or the integrated mail may be transmitted.
Further, the e-mail relay apparatus 100 transmits the URL of the manufacturer of the device 200, the e-mail address of the contact person of the support person, the telephone number, etc. to the e-mail recipient terminal apparatus 500 together with the failure notification e-mail 600 or the integrated e-mail. Also good.
Further, the electronic mail relay apparatus 100 may store past electronic mail exchanges, and if the same event occurs, the electronic mail relay apparatus 100 may transmit a reference past electronic mail. .
Further, the e-mail relay apparatus 100 may transmit the manual or the recovery procedure manual of the faulty device 200 attached to the fault notification mail 600 or the integrated mail.
When the transmitted failure notification mail 600 or the integrated mail has a transmission error, the electronic mail relay device 100 may retry the transmission of the failure notification mail 600 or the integrated mail that has caused the transmission error.
Further, the e-mail relay apparatus 100 may transmit the failure notification mail 600 or the integrated mail in parallel to the mail provider apparatuses 300 of a plurality of ISPs (Internet Service Providers).
Further, the electronic mail relay device 100 may periodically report to the mail recipient terminal device 500 that the failure notification mail 600 has not been received.
