I am trying to use the NXSL command "AgentExecuteAction".

In the configuration file of my agent, I have placed:

ExternalParameter = Test:echo test > /tmp/test.txt

This works very well on the command line:

/opt/netxms/bin/nxget localhost 'Test

# more /tmp/test.txt
test

So, I made a very small script  ;):

AgentExecuteAction($node, "Test");

I execute it...
I can see the action in debug mode:

  ** code=0x0043 (CMD_ACTION) version=5 flags=0x0000 id=4 size=56 numFields=3
  ** 000000: [    87] UTF8-STRING "Test"

but it doesn't work ...

Is it a syntax problem?
A Parameter problem?

Thanks
