Virtual School Day

[chumguy]

We had a virtual school day yesterday. Teachers used various technologies including Google Hangouts, BigBlueButton, and other technologies like chat. We hadn't tested BBB under such a load and this was trial by fire. The 4 CPUs ran maxed most of the day. The sockets have been doubled on the VM and BBB now has 8 CPUs. Now its time to re-read the docs and do some stress testing before the next snow storm. :-)

Thanks for BBB,

Robert

I've been trying to get my head around bandwidth usage. I've tested with Fred's bbb-test.sh script and am trying to get a script together that runs under Windows, since that is what we have more to test with. 

Save the script as bbb-test.vbs and run it with cscript bbb-test.vbs host N Y, where N is the number of clients to launch and Y is the client start number to append to the user ID. The Y parameter lets one start say at 6, after having 5 users already started. Here's the script. I'm not much of a programmer, so please forgive any errors.

Thanks,

Robert

PS This has been tested on Windows 10 and IE 11 and the beta of BBB.

Dim IE

Dim testHost

Dim testClients

Dim startClient

Dim SecondsDelay

Dim urlString

Dim invalidInput

invalidInput = 0

startClient = 0

SecondsDelay = 3000

if WScript.Arguments.Count <> 3  then

    WScript.Echo "Usage: cscript bbb-test.vbs host N Y"

WScript.Echo "Host is the hostname or IP address and N is the number of clients to start."

WScript.Echo "Y is the user number to start with."

invalidInput = 1

else

testHost = WScript.Arguments.Item(0)

testClients = WScript.Arguments.Item(1)

startClient = WScript.Arguments.Item(2)

end if

 

If invalidInput = 0 Then

Set IE = CreateObject("InternetExplorer.Application")

IE.Visible = 1 

startClient = startClient - 1

for i = 1 to testClients

urlString = "http://"&testHost&"/demo/demo1.jsp?action=create&username=User"&i+startClient

if i = 1 then

IE.Navigate urlString

else

IE.Navigate urlString,,"_blank"

End If

WScript.Sleep SecondsDelay

Next

End If

This script works with Windows 7 and IE 10. Now to figure out how to test against a server without the demo stuff installed. :-)
