Is it possible to run inline Groovy with Invoke-LMCollectorDebugCommand?

[rdmarsh]

I’m trying to figure out how to pass Groovy code with Invoke-LMCollectorDebugCommand, and I’m not sure it’s possible.

There isn't much documentation from LogicMonitor, and everything I’ve tried so isn't working.

Here’s a minimal example that fails:

Invoke-LMCollectorDebugCommand -Id 241 -GroovyCommand "println 'hello world'" -IncludeResult

which relults in this error:

Error when executing the script -

exception:org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed:
Script1148.groovy: 8: Unexpected input: '{\n    hostProps = CollectorDb.getInstance().getHost("").getProperties();\n    instanceProps["wildvalue"] = "";\n    }\ncatch' @ line 8, column 1.
   catch(Exception e) {
   ^

1 error

If I open the collector debug console, open the groovy popup window and run Groovy manually, it works fine:

$ !groovy
returns null
output:
hello world

The only clue I have that I can pass groovy to the the collector is the help output. The second usage suggests the collector should accept inline "scriptbody" if prefixed with \n, but I haven’t managed to get anything working on the console or the PowerShell wrapper.

$ help !groovy
Usage:
    !groovy [options] scriptFilePath
    !groovy [options] \nscriptbody
Options:
    timeout: timeout in seconds, default 180 seconds
    runner: where to run the script. Runner must be agent or sse, and agent is the default runner
    hostId: send which host(in the portal) properties to groovy runner.
    h: indicates which host(in the collector) the hostProps will bound to
Arguments:
    scriptFilePath: specify the script path in collector side for executing
    scriptbody: embedded script body from the !groovy popup window

Has anyone managed to send inline Groovy to a collector using Invoke-LMCollectorDebugCommand or via the collector debug window? Is inline Groovy supported, or is the help text misleading?

Any working example or clarification would be appreciated.

You should be able to achieve what your trying to do via the PowerShell module/Rest API. It's been a minute since I've personally tried to run a remote groovy cmd via the module but let me take a look and see what's causing the issue if any. I don't have a unit tests for this particular cmdlet due to the nature of how it works but let me check if possibly the API structure has changed.

@rdmarsh I think I see what the issue was. I just released a new version 7.7.4 that fixes the issue. I have some pre execution code that runs when using the inline -GroovyCommand that I have to autoPopulate the hostProps and instanceProps when specifying a -CommandHostName and -CommandWildValue:

!groovy
import com.santaba.agent.collector3.CollectorDb;
def hostProps = [:];
def instanceProps = [:];
try {
    hostProps = CollectorDb.getInstance().getHost("$CommandHostName").getProperties();
    instanceProps["wildvalue"] = "$CommandWildValue";
    }
catch(Exception e) {

};

Somehow it was picked up and reformatted by my code linting. I went and fix the bug if you want to try running that v7.7.4 version and see if that fixes your issue:

Thanks for this fix! Finally got back to looking at this.

I'm not 100% sure why but for some reason having the single quotes on the outside doesn't always return any results.

Invoke-LMCollectorDebugCommand -Id 2 -GroovyCommand 'println "hello world"' -IncludeResult
Invoke-LMCollectorDebugCommand -Id 2 -GroovyCommand 'println "hello world"' -IncludeResult
returns null
output:
hello world

Invoke-LMCollectorDebugCommand -Id 2 -GroovyCommand "println 'hello world'" -IncludeResult
returns null
output:
hello world

Anyway, thank you for the fix!
