Disabled SNMP debug log is huge

Thanks Felix,
you got it. Only thing was that I had to broaden my search a bit as I found the following string: <snmpdebuglog> <flags> <inherited/> </flags> <cell> 1 </cell> </snmpdebuglog> I don't recall changing this setting, but it's possible. I'm a newby so I've been playing around a lot.

Stopped PRTG services, deleted the log, restared services. So far no new log. Thanks again!!!

Also noticed that "SCHEDULES, DEPENDENCIES, AND MAINTENANCE WINDOW" has inheritance disabled at the device level for all devices. Don't recall making all those changes either.

The following script will make it easier for you to discern which objects have SNMP debug enabled:

# requires --version 4
#region configuration
[string] $ConfigurationFilePath = ((Get-ItemProperty -Path "hklm:SOFTWARE\Wow6432Node\Paessler\PRTG Network Monitor\Server\Core" -Name "Datapath").DataPath) + "PRTG Configuration.dat"
   [xml] $configuration = New-Object -TypeName XML;
         $configuration.Load($ConfigurationFilePath);
$groups = $configuration.SelectNodes("//group") 
$devices = $configuration.SelectNodes("//device") 
#endregion



$GroupList = foreach($group in $groups){
    
    $DebugLog = $False; 

    try{
       $value = $group.data.snmpdebuglog.trim();
       If($value -eq 1){ $DebugLog = $True; }
       Else{$DebugLog = $False; }
    }
    catch
    {
        #$DebugLog = $Device.data.snmpdebuglog.trim();
    }

    if($DebugLog -eq $True){

        [pscustomobject]@{
            ID = $group.id;
            Type = "Group"
            Name = $group.data.name.Trim(); 
            "SNMP Debug" = $DebugLog;
            
        }

    }
}

$DeviceList = foreach($Device in $devices){

     $DebugLog = $False; 
    
    try{
       $value = $device.data.snmpdebuglog.trim();
       If($value -eq 1){ $DebugLog = $True; }
       Else{$DebugLog = $False; }
    }
    catch
    {
        #$DebugLog = $Device.data.snmpdebuglog.trim();
    }

    if($DebugLog -eq $True){

    [pscustomobject]@{
        ID = $device.id;
        Type = "Device"
        Name = $device.data.name.Trim(); 
        "SNMP Debug" = $DebugLog; 
        
    }
    }
}

$GroupList
$DeviceList

It will output all groups and devices that have snmpdebug enabled like this:

Simply save it as Get-DebugPRTGObjects.ps1 on the PRTG Core Server and execute it.
