Hi Guys,

after deploying SCOM 2016 (Upgrade from 2012 R2) I am seeing this error a lot in the Operations Manager Log on many servers.

Microsoft.Windows.Server.OperatingSystem.PercentMemoryUsed.vbs : Invalid number of arguments (1 instead of 2). Arguments: {3642.}

Management Pack for Windows OS is 6.06729

any clue?

thanks

Hey Mayor,

Would recommend upgrading the management pack as a first step, you’re running a few versions behind.  
Maybe there is some kind of incompatibility between SCOM 2016 and the MP version you are using.

Br,

Jasper

Have you tried clearing the healthstate cache on the servers giving the error?

There was a bug in one of the older UR’s for 2016 - This has now been resolved. Hopefully, you’ve already upgraded and the issue is solved 🙂
