Receive. Note that the order in which the alarms arrive at the alarm monitoring apparatus 1 is not necessarily the first arrival of the alarm transmitted by the transmission apparatus 202-1, but arrives in any order.
- the monitoring control unit 11 checks the hold timer for the path related to the received alarm.
- the hold timer is a timer for waiting for processing for displaying a path related to the received alarm in the alarm-occurring path list for a period set by the timer after receiving the alarm. This is to prevent the content displayed in the alarming path list from being frequently updated in a short time.

When the hold timer is not activated (step S2: No), the monitoring control unit 11 activates the hold timer for the path indicated by the related path ID (step S3), and registers the alarm in the alarm DB 14 (step S3). S4). On the other hand, when the hold timer is activated for the path indicated by the related path ID included in the alarm (step S2: Yes), the monitoring control unit 11 registers the alarm in the alarm DB 14 (step S4). The monitoring control unit 11 repeatedly executes all the alarms that have received the above processing.
- FIG. 8 is a flowchart showing the processing until the alarm occurrence path list is displayed.
- the monitoring control unit 11 sorts alarm information having the path ID of the related path associated with the hold timer in the alarm DB 14 (step S12).
- the supervisory control unit 11 extracts an alarm having the highest priority alarm importance from the sorted alarms (step S13). For example, when three alarm importance levels of Major, Minor, and Warning are defined, and the alarm database includes Major, Minor, and Warning alarms, the monitoring control unit 11 extracts the Major alarm. In addition, if only Minor and Warning alarms are included, Minor alarms are extracted.
- the monitoring control unit 11 selects the alarm having the latest detection time from the extracted alarms having the highest priority, and sets the selected detection time as the alarm occurrence time (step S14). Then, the monitoring control unit 11 registers the alarm importance level and the alarm occurrence time determined above as data of the corresponding path in the path DB 13 (step S15).
- the supervisory control unit 11 confirms whether or not the display mask flag of the corresponding path is ON in the path DB 13 (step S16), and when the display mask flag is OFF (step S16: No), it is registered in the path DB 13.
- the path ID, the alarm importance level, and the alarm occurrence time are displayed on the display unit 12 as an alarm occurrence path list (step S17). At this time, if there is a path that is already displayed, the paths are sorted according to the alarm occurrence time, and the path having the newest alarm occurrence time is displayed at the top of the list.

- FIG. 9 is a diagram illustrating a relationship between a transmission path and a path.
- WDM Widelength Division Multiplex
- a large number of wavelengths are multiplexed on one optical cable, and each is used for communication of different information. That is, several tens or hundreds of paths are used for one optical cable. Note that the Ingress transmission device and the Egress transmission device of these paths do not always match.
- a failure such as a disconnection of a transmission path (for example, disconnection of an optical cable that is a transmission path between the communication nodes 100-2 and 100-3 in FIG. 9) occurs in such a communication network, a large number of paths are failed at once.
- each path is displayed in the alarming path list by the above-described processing at the time of alarm generation.
- FIG. 10 is a flowchart showing processing when a display mask is designated.
- the monitoring control unit 11 sets a transmission device or a transmission path for which the display mask is specified, for example, a transmission path between the communication nodes 100-2 and 100-3.
- the passing path is searched in the path DB 13 (step S22), and the display mask flag of the passing path is turned ON (step S23). Then, after clearing the display of the alarming path list (step S24), the monitoring control unit 11 displays each path whose display mask flag is OFF in the alarming alarm list (step S25). As a result, a path for which an alarm has been generated due to a known failure, for which an operator has designated a display mask, can be hidden from the alarm-occurring path list.
- step S15 may be displayed as it is in the alarming path list in step S17.
- the monitoring control unit 11 has the highest priority for each path for each path ID. Only the latest alarms with a high alarm importance are displayed as a path list during alarm occurrence. As a result, each fault-occurring path is displayed in one line with the alarm severity, and the operator can check the status of many paths at the same time. The process can be started.
- the monitoring control unit 11 sorts the alarm occurrence path list by the alarm occurrence time, and displays the path having the latest alarm occurrence time at the top. As a result, in the path where a failure has already occurred, if a failure unrelated to the previous failure occurs over time, the path display is changed to the top of the list, so the operator can easily create a new failure. Can be recognized.
- the monitoring control unit 11 updates the path in which an alarm is generated after a specified time after the first alarm is generated using the hold timer.
- a communication network is a wide area network such as a submarine cable system and a time lag occurs at the time when an alarm transmitted from each communication node arrives at the alarm monitoring device 1, a large number of problems occur due to one failure. Since the alarm DB 14 is not searched for each of the alarms, the processing load on the monitoring control unit 101 can be reduced.
- the monitoring control unit 11 processes the selection of alarm information to be displayed in the alarm-occurring path list based on the alarm importance and the occurrence time regardless of the alarm type. Therefore, even when a new device is added to the communication network and the alarm types increase, the alarm monitoring device 1 does not need to correct the alarm types.
- the display mask function is used for the path through the transmission path or transmission device in which the operator has a known failure. It can be hidden from the alarming path list. Thereby, the operator can easily find the alarm-in-progress path derived from another fault unrelated to the known fault in the alarm-in-progress path list.

When the alarm occurrence time of the path is earlier than the display mask end time (step S59: No), the monitoring controller 11a ends the process without displaying it in the alarm occurrence path list.
- the monitoring control unit 11a sets a specified time for non-display for a path to be displayed masked, and an alarm is being generated for the specified time for a path corresponding to the display mask. It was decided not to display in the list. As a result, alarms related to the recognized failure will not be displayed in the alarming path list only for the specified time after the alarm arrives at the alarm monitoring device, and alarms that are not related to the already recognized fault will be newly displayed on the path. Can be displayed in the alarm-occurring path list, and the operator can find an alarm when a failure having no dependency occurs on the same path.
- the alarm monitoring apparatus is useful for network monitoring, and is particularly suitable for a network in which a plurality of alarms for the same cause occur.
