Sometimes or other we might need to retain the max size of log files for reading/analyzing. Here are some useful info………… in this regards…………. Client side reference registry For X86 systems           HKLMSoftwareMicrosoftCCMLogging@GLOBAL For X64 systems           HKEY_LOCAL_MACHINESOFTWAREWow6432NodeMicrosoftCCMLogging@GLOBAL   The reference key is Log Maxsize I tried to change manually by regedit how it is showing error as can’t be edited the value.. So I depended on below WMI script

‘ VBScript to change the Log File Size on a ConfigMgr client ‘ Change the 500000 to your required size in bytes   Dim newLogMaxSize Dim sMachine newLogMaxSize = 500000 sMachine = “.” set oCCMNamespace = GetObject(“winmgmts://” & sMachine & “/root/ccm”) Set oInstance = oCCMNamespace.Get(“SMS_Client”) set oParams = oInstance.Methods_(“SetGlobalLoggingConfiguration”).inParameters.SpawnInstance_() oParams.LogMaxSize = newLogMaxSize oCCMNamespace.ExecMethod “SMS_Client”, “SetGlobalLoggingConfiguration”, oParams ‘ End of script   So Do not change the registry value directly!   The SDK shows the SetGlobalLoggingConfiguration Method in Class SMS_Client
