Hi,
I'm currently trying to get an external parameter on a Windows host working.
NetXMS Version as well as the Agent version is 2.1.
The Agent Policy
ExternalParameter=Ext.grep_count(*):powershell.exe -command "Select-String -Path \"$1\" -Pattern \"$2\" | Measure-Object | Foreach-Object { echo $_.Count }"
gets called, but reports "_.Count" as value of the Parameter.
I assume that the "$_.Count" gets replaced by NetXMS somewhere by "_.Count", so the echo returns this string only.
Is there a way to escape "$" in the Agent Policy ? I already tried to "\$_.Count" (returning \.Count as value).
Kind regards,
Thomas
PS: as the External parameter is called, I think you can cancel https://track.radensolutions.com/issue/NX-1233
Hi Thomas,
$ marks a parameter passed by NetXMS, hence $_ will not work for you.
For a literal $, write $$, so your line would look as follows:
ExternalParameter=Ext.grep_count(*):powershell.exe -command "Select-String -Path \"$1\" -Pattern \"$2\" | Measure-Object | Foreach-Object { echo $$_.Count }"
Cheers
