Instatiate a Probe via Script (Business Rule)

[mahmoudhabiball]

Hi,

I am new to ServiceNow and I could find no right solution for my Problem (Out of the box)

I have defined a PowershellProbe with a script which recieves a Parameter (powershell_param_someparam).

Running the Script from on the GUI works successfully, yet I have no idea how would I be able to Access and Trigger this Pobe from a bussiness rule or another script type.

Is there any way to do it?

Hello Mahmoud,

You can write a script include and call the script from business rule. Below is the example.

PowerShellExecScript: function(scriptName, inputsJson) {

              var midServer = gs.getProperty('mid.server.rba_default');

var grScriptRecord = new GlideRecord('ecc_agent_script_file');

grScriptRecord.addQuery('name', scriptName);

var script;

grScriptRecord.query();

if (grScriptRecord.next()){

      script = grScriptRecord.script;

gs.log('PowerShellExecScript: found script ' + scriptName);

}

else {

gs.log('PowerShellExecScript:Cannot locate script ' + scriptRecord );

}

var inputsObj =   new global.JSON().decode(inputsJson);

var scriptParamed= script;

for(var propertyName in inputsObj) {

scriptParamed= scriptParamed.replace('%%SN:' + propertyName + '%%',inputsObj[propertyName]);

      }

var psProbe= new PowershellProbe( midServer, '127.0.0.1');

psProbe.setScript(scriptParamed);

var psResponse = psProbe.execute(true);

gs.log('Executed powershell probe');

gs.log('PowerShellProbe:'+ scriptName.toString()   +'\n\tOutput: ' + psResponse.output + '\n\tError: ' + psResponse.error);

gs.log('Executed PS script ' + scriptName + '\nOutput: ' + psResponse.output );

return psResponse.output;

},

Thanks,

Jag.

This line is my Problem: var psProbe= new PowershellProbe( midServer, '127.0.0.1');

The script doesn't continue processing the script after this line. Do I Need to install any Feature or enable any plugin to be able to instantiate a PowershellProbe object?

Hello Mahmoud,

Would you be able to provide your code. So, that i can check it.

Thanks,

Is is not about the script. Every time I try to instantiate the Powershell Object, the script Fails. The breakpoint is being and it Fails after that.

so a script like this one   in a Business rule would fail:

(function executeRule(current, previous /*null when async*/) {

var psProbe= new PowershellProbe( "mid.server.midserver_scom", '127.0.0.1');

})(current, previous);
