Windows Script host Ruby monitor

In SAM when creating a "Windows Script Monitor" with the "Script Engine" set to rubyscript, I can't acces script arguments in a ruby script invoked through WSH.

The following VB code works fine with the "Script Engine" set to vbscript.

WScript.Echo "Statistic.0:", WScript.Arguments.Length

WScript.Echo "Message.0: there are ", WScript.Arguments.Length, " arguments"

With script arguments a b c d

Produces

Script Output:

Message.0:	there are 4 arguments
Statistic.0:	4

However, the following ruby code with the "Script Engine" set to rubyscript, does not give the expected results.

puts "Statistic.0: #{ARGV.length}"

puts "Message.0: there are #{ARGV.length} arguments"

With script arguments a b c d

Produces

Script Output:

Message.0:	there are 0 arguments
Statistic.0:	0

Can anybody, confirm, deny, or fix this please?ruby wsh

Hello,

SAM is using cscript.exe to execute Windows Script Monitor.

The first thing you should try is to run your script manually from a command line using following syntax:

cscript.exe /E:rubyscript path_to_your_script_file argument1 argument2

This will confirm if cscript.exe and Windows Script Host works correctly with RubyScript or not

Martin,

thanks for the reply.

I should have been more specific. Invoking either a VB script or a Ruby script using cscript.exe directly works fine. Both scripts detect and report on the script arguments correctly.

It's only when SAM is involved in running the Ruby script that the script parameters get lost. If SAM is indeed running the script by invoking cscript.exe then it is either not passing the parameters correctly or not at all, when the script in question is a Ruby script.

Cheers, Mike

Hello,

SAM invokes the scripts by running a cscript.exe and passing everything on the command line as if you would run it on the command line manually.

I've tried to install ActiveRuby 1.8.7 on Windows 2008 R2 x64, but I'm unable to get it work properly with Windows Script Host (cscript.exe).

What Windows (2003/2008/x86/x64) are you running Orion on? What version of Activy Ruby are you using?

Just to confirm, you were able to run the ruby script manually through cscript.exe on Orion box, not on any other machine, right?

Otherwise I would suggest following steps to get more details:

Go to 'Edit Application' page of the application with this script monitor and enable Debug Logging

Test the Windows Script Monitor component, which uses ruby script and when the test is finished, the log file will be generated on disk
To find the right log file, you need to check 'ID' parameter value from URL and then navigate to appropriate directory

The log file will show what command line SAM used to execute the script

Could you confirm that command line shown here is correct and works if executed manually from the command line on Orion box under the same credential as SAM is using?

When you assign the script template to the node are you going back to the script you just assigned on the node and running the script output for the first time under Edit?. It won't work unless you do since the full use of SAM wants to know what output statistics to expect. Once you run the output for the first time the SAM template will re populate with more fields for each output statistic you are expecting to populate on the graphs/charts on the details page.

Try this and see if it will start working.
