监视网络设备上的可用内存量
该监视器指示此设备上的可用内存级别。 此监视器有两种可能的状态:
正常: 已用可用内存的百分比高于阈值。
错误: 已用可用内存的百分比低于阈值。
可以为此监视器配置以下选项:
选项 | 定义 | 默认 |
间隔 | 检查设备状态时间间隔(以秒为单位) | 240 秒 |
重试次数 | 在丢弃时间间隔样本之前,每个监视时间间隔中的尝试次数 | 3 |
样本数 | 监视器更改状态之前的连续样本数 | 3 |
超时 | 样本超时并重新尝试对值进行取样之前等待设备响应的时间量(以毫秒为单位) | 3,500 毫秒 |
阈值 | 剩余可用内存百分比 | 15 |
此监视器在接口上的可用内存量低于配置的阈值时进入错误状态。 默认值为 15%
使用运行状况资源管理器,在监视器的“状态更改事件”选项卡上检查状态更改的详细信息。 此数据显示计算所得的性能计数器值,该值导致运行状况状态发生更改。 有关问题和故障排除过程的详细信息,请查阅设备制造商的文档。
