Changing the "Default Limits" on the general tab on "wmidiskspace" sensors

[xasz]

What's going on?

Hello lordmilko,

i am trying to get / set the default limits of an wmidiskspace settings which are listed on the settings tab on the prtg: I have checked the New-SensorParameters:

But i could not figure out if or how i could change these values. I appreciate any help or hint and thank you again for your nice work.

• [X] It wasn't covered by the wiki, I swear!
• [X] I have tried doing some basic research on this issue but haven't been able to come up with anything. Please help!

Hi @xasz,

It looks like these settings can only be changed after the object has been created; therefore the cmdlets you are looking for are Get-ObjectProperty and Set-ObjectProperty respectively

C:\ Get-Sensor -Id 2061 | Get-ObjectProperty -Raw

name                            : Disk Free (Paused Sensor)
parenttags                      : C_OS_VMware TestGroup TestProbe
tags                            : diskspacesensor wmidiskspacesensor
limitpercent                    : 0
upperlimiterrorpct              :
upperlimitwarningpct            :
lowerlimitwarningpct            :
lowerlimiterrorpct              :
limitbytes                      : 0
upperlimiterrorbyte             :
upperlimiterrorbyte__factor     : 9.5367431640625E-7
upperlimitwarningbyte           :
upperlimitwarningbyte__factor   : 9.5367431640625E-7
lowerlimitwarningbyte           :
lowerlimitwarningbyte__factor   : 9.5367431640625E-7
lowerlimiterrorbyte             :
lowerlimiterrorbyte__factor     : 9.5367431640625E-7
erroronmissingdisk              : 0
writeresult                     : 0
stack                           : 0
...

To modify these properties you'll need to construct a request specifying all of the required raw parameters

C:\ Get-Sensor -Id 2061 | Set-ObjectProperty -RawParameters @{
    limitpercent_ = 1
    upperlimiterrorpct_ = 30
} -Force

Don't forget to add the trailing underscore to each property name!

Note that if you wish to modify the byte limit of the sensor rather than percent you'll need to specify the factor as well (might be easiest to store the output of Get-ObjectProperty -Raw in a variable and pull the relevant factors from the variable rather than hard coding any particular value)

For more information please see the wiki

Thank your lordmilko - that helped alot.

For anyone who exactly does need this, this works fine for me and as far as i have seen have not caused any trouble:

$param = $prtgDevice | New-SensorParameters -RawType wmidiskspace
$param.Name = $SensorName
# some more settings
$prtgDevice | Add-Sensor $param | Set-ObjectProperty -RawParameters @{lowerlimitwarningpct_ = 15; lowerlimiterrorpct_ = 15} -Force
