当 Cisco 路由器的接口吞吐量超过某个值时，我正在尝试生成警报。请看一下我的代码。

我正在使用电报收集数据。我的测量“监控使用情况”包含多个字段键和值。如何将它们分开并警告它们？我是否正确使用“衍生”节点？它是我应该在“衍生”节点中使用的字段键吗？

有没有办法记录每个节点的输出以帮助排除故障？在我的情况下，我如何看到由“alert”节点计算的“bytes_recv_per_sec”值？

“日志”节点究竟做了什么？日志文件在哪里？我在“/var/log/kapacitor/kapacitor.log”中没有看到太多有价值的信息

我试过用不同的参数方法玩不同的节点，但没有多大成功。谢谢你的帮助。

dbrp "telegraf"."autogen"

stream
    |from()
        .measurement('monitor usage')
        .where(lambda: "agent_host" == '10.92.192.15')
    |window()
      .period(1m)
      .every(1m)
    |httpOut('dump')
    |stats(1m)
    |httpOut('stats')
    |derivative('Envision_Po1.891_ifHCInOctets')
        .unit(1s).nonNegative()
        .as('bytes_recv_per_sec')
    |alert()
        .warn(lambda: "bytes_recv_per_sec" > 40.0)
        .crit(lambda: "bytes_recv_per_sec" > 80.0)
         // post to logfile
        .log('/tmp/alerts.log')

在这个阶段，我想查看“/tmp/alerts.log”以在达到警报阈值时生成一些警报消息。最终我想发送一封警报电子邮件。

根据要求，这里是关于“监视器使用”测量的数据库信息
