Monitoring device and monitoring system
A monitoring device includes a transmitting unit, a receiving unit, and a determining unit. The transmitting unit transmits, to a plurality of base stations, instructions on mutual monitoring among the base stations. The receiving unit receives, from a base station that has detected abnormality of a base station serving as a monitoring target in accordance with the instruction among the base stations, information indicating a base station determined as having abnormality. The determining unit determines a level of a fault that has occurred in the base station indicated by the information received by the receiving unit.
1. A monitoring device comprising:
a processor that executes a process including:
transmitting to a plurality of base stations, instructions on mutual monitoring among the base stations;
receiving from a base station that has detected abnormality of a base station serving as a monitoring target in accordance with the instruction among the base stations, information indicating a base station determined as having abnormality; and
determining a level of a fault that has occurred in the base station indicated by the information received at the receiving, wherein
the instructions include a list of base stations to be monitored by the base stations and a monitoring period,
the list registers the base stations to be monitored such that the base stations to be monitored slightly differ for each of the base stations that perform monitoring, and
the list is designed such that all of the base stations have equal monitoring load in an entire monitoring system.
2. The monitoring device according to claim 1 , wherein
the process further includes generating a histogram of number of abnormality reports within a predetermined monitoring period by using the information received at the receiving, and
the determining includes determining the level of the fault based on a distribution ratio of the histogram generated at the generating.
3. The monitoring device according to claim 1 , wherein the information includes identification information and an internet protocol (IP) address of the base station determined as having the abnormality.
4. A monitoring system that includes a plurality of base stations and a monitoring device that monitors the base stations, wherein
the monitoring device includes:
a first processor that executes a first process including:
first transmitting, to the base stations, instructions on mutual monitoring among the base stations;
first receiving, from a base station that has detected abnormality of a base station serving as a monitoring target in accordance with the instruction among the base stations, information indicating a base station determined as having abnormality; and
determining a level of a fault that has occurred in the base station indicated by the information received at the first receiving, and
each of the base stations includes:
a second processor that executes a second process including:
second receiving the instruction transmitted by the monitoring device;
monitoring the other base stations in accordance with the instruction; and
second transmitting, upon detection of abnormality in any of the other base station as a result of the monitoring, information indicating the base station determined as having abnormality to the monitoring device wherein
the instructions include a list of base stations to be monitored by the base stations and a monitoring period,
the list registers the base stations to be monitored such that the base stations to be monitored slightly differ for each of the base stations that perform monitoring, and
the list is designed such that all of the base stations have equal monitoring load in an entire monitoring system.
