Not able to Run Powershell Script using NRPE

[CloudOps]

Hi All,

I am not able to run Powershell script using NRPE, i am getting below error :

[root@VM-NAGIOSXI-TEST libexec]# ./check_nrpe -H 172.26.2.13 -c topcpu
The command (topcpu) returned an invalid return code: -196608
[root@VM-NAGIOSXI-TEST libexec]#


I have changed the powershell excution ploicy to remote signed. I am attaching my nsclient configuration file.

Your command:

Code: Select all

topcpu = cmd /c echo scripts\resourcecheck.ps1; | powershell.exe -command 

Not sure why you're using the echo, and suspicious of the relative path. You're also piping the string "scripts\resourcecheck.ps1" to powershell, not the contents of resourcesheck.ps1. Run this to see:

Code: Select all

cmd /c echo scripts\resourcecheck.ps1

You'd need to change it to something like to make it work, but even then you're using cmd.exe and PS, which is a turtle all by itself:

Code: Select all

cmd /c type c:\path\to\scripts\resourcecheck.ps1

Maybe copy your script to the plugins dir and execute from there:

Code: Select all

topcpu="powershell.exe C:\Program Files\NSClient++\plugins\resourcecheck.ps1"

First get the command to run from any dir in a cmd.exe window before attempting to run from nsclient.

I created a test.ps1 that just ad dir in it and it ran as:

Code: Select all

powershell.exe test.ps1 and simply test.ps1

I'd associate ps1 w/ powereshell.exe (if not already done):

Code: Select all

topcpu="C:\Program Files\NSClient++\plugins\resourcecheck.ps1"

Can you run the "resourcecheck.ps1" script locally, on the Windows machine, and show the output? Do you mind showing the actual script?

i have modified the path, now i am getting below error :

./check_nrpe -H 172.26.2.13 -c topcpu -t 160
CHECK_NRPE: Received 0 bytes from daemon. Check the remote server logs for error messages.

In nsclient logs i can see the below error :

2016-03-23 04:04:02: error:c:\source\nscp\include\socket/connection.hpp:149: Failed to send data: The file handle supplied is not valid

Paste the following into a cmd prompt window on 172.26.2.13 and paste the result. Don't run it from the plugins dir.

Code: Select all

"C:\Program Files\NSClient++\plugins\resourcecheck.ps1"

@CloudOps
Can you zip up your "resourcecheck.ps1" script, and upload it on the forum?

[rkennedy]

Please post the powershell file for us to look at.

In addition to posting the script try running it:

Code: Select all

powershell.exe "C:\Program Files\NSClient++\plugins\resourcecheck.ps1"
