Zee Script to monitor CPU performance

[rmasonjr]

The following script can be used to track the CPU averages of your Zee.
It uses the linux uptime command which returns 3 load averages at 1m, 5m and 15m. Since it is an average, it provides a pretty decent mechanism for tracking the CPU performance.

Save the following script as ZeeCPU.vb
Setup a recurring event to run from the top of the hour, every 15 mins.

I'd be curious to see your results.

Sub Main(parm as object)

dim proc as System.Diagnostics.Process
dim resp,s as String
dim ary() as String
dim i as Integer
dim sw as System.IO.StreamWriter

Try
     proc = new System.Diagnostics.Process()
     proc.StartInfo.FileName="/usr/bin/uptime"
     proc.StartInfo.UseShellExecute=False
     proc.StartInfo.RedirectStandardOutput = True
     proc.Start()
     resp=proc.StandardOutput.ReadToEnd()

     ary = resp.Split(New Char() {","c})

     If(UBound(ary)>=4) then
          sw = new     System.IO.StreamWriter("/usr/local/HomeSeer/Data/ZeeCPUPerformance.txt",True)
          sw.Write(Now() & "," & ary(4))
     End If

Catch ex as Exception
     hs.writeLog("Exception",ex.message)
Finally
     If(not sw Is Nothing) then
          sw.Close()
     End If
End Try

End Sub 

You can open the file and view the log file using WinSCP or PuTTY.

Found another interesting application.
