    • A network monitoring device which monitors a network in which data is transmitted through relays, includes a monitoring frequency recording unit (111) which records monitoring frequencies for monitoring transmission statuses of the relays, a selection probability generating unit (112) which generates selection probability information which is probability values for the relays, a monitoring object determining unit (113) which determines, according to the monitoring frequency and the selection probability information, a relay the transmission status of which is to be monitored, a transmission status obtaining unit (106) which obtains transmission status information indicating a transmission status on the relay determined, a transmission status recording unit (107) which records the transmission status information, an activation level calculating unit (109) which calculates, using the transmission status information, activation level indicating suitability of the monitoring on the transmission statuses of the relays, and a monitoring frequency updating unit (110) which updates, based on the activation level, the monitoring frequency, and the network monitoring device detects the change in throughput on a data transmission path highly responsively.
    • 一种监视通过中继发送数据的网络的网络监视装置,包括:监视频率记录单元,其记录用于监视所述中继的发送状态的监视频率;生成选择概率信息的选择概率生成单元, 一个监视对象确定单元,根据监视频率和选择概率信息,确定其发送状态将要被监视的中继;发送状态获取单元, 获取表示所确定的中继的发送状态的发送状态信息,记录了发送状态信息的发送状态记录部(107),使用发送状态信息计算表示适合性的激活电平的激活电平计算部(109) 的监测 继电器的状态,监视频率更新单元(110)基于激活水平更新监视频率,并且网络监视设备高度响应地检测数据传输路径上的吞吐量变化。
