Powershell可以将计数器值放入系统托盘中吗？

Question

我正在尝试在系统托盘上以数字方式监控我的Wifi适配器的吞吐量;像这样。

我想出了静态的Powershell查询

((Get-Counter '\\mullick1\network interface(intel[r] centrino[r] advanced-n 6205)\bytes total/sec').countersamples).cookedvalue*8/102400000*100

但是如何获得连续进纸以及如何将其放在系统托盘上？ 我在Diskled软件中找到了备用解决方案。但它没有显示实际价值。

这是在通知图标上呈现（更新）文本的脚本。

根据需要自定义“Get-NotifyIconText”功能。

#Requires -Version 3.0

function Get-NotifyIconText {
  [DateTime]::Now.Second.ToString()
 # ((Get-Counter '\\mypc\network interface(Intel[R] 82579V Gigabit Network Connection)\bytes total/sec').countersamples).cookedvalue*8/102400000*100
}
