we decided not to add that channel to our existing exchange sensors, because even Microsoft says to get reliable data on the whitespace of a database you need to dismount the database and use ESEUTIL

Hi,

as this is the first request for adding this channel we want to make a script available for you to see if this value is usefull and to give other customers the chance to comment on it.

As you can see, the request itself and parsing the value is only a 3 liner + output, the rest of the script may be cut off but it may be helpful in case of an error.

Simply pack the following script in a .ps1-file that must be stored in the 'Custom Sensors\EXEXML'-folder of your PRTG-Installation. After that you can add it as a 'EXE/Script Advanced'-sensor.

Param(
        [string]$server, 
        [string]$user,
        [string]$password, 
        [string]$item="Mailboxdatabase"
    )

# To get this script running with PRTGNetworkMonitor you need to enable RemoteSigned-scripting for 32bit-processes. 
# This can be done with running 'c:\Windows\SysWOW64\WindowsPowerShell\v1.0\powershell.exe "Set-ExecutionPolicy RemoteSigned"' on a system with default paths


# Examples of Parameters-string in sensorsettings

# Environment ->'Set placeholders as environmentValues':
#   -item MailboxDataBase
# Environment ->'Default Environment':
#   -server %host -user %windowsdomain\%windowsuser -password %windowspassword -item MailboxDatabase
#   -server <ip-address or fqdn of the host> -user <domainname>\<username> -password <password> -item MailboxDatabase


# declare script-wide variables
$warningpreference = "silentlyContinue"
$script:resultText = "OK"

        
function main {
    $statis =  Get-MailboxDatabase -status $item; 

    $statis.AvailableNewMailboxSpace -match "[\(]{1}(.*?)\bbytes[\)]{1}"
    $value = [long]$matches[1]; 
    
    $result = @"
  <result>
    <value>$value</value>
    <unit>BytesMemory</unit>
    <channel>Available New Mailbox Space</channel>
  </result>

function checkCredentials {
    $paramerrors = @() 
    if ($server -eq $null) {
        if (-not ($Env:prtg_host -eq $null)) {
            $script:server = $Env:prtg_host

When you are running the script from the commandline, which output do you get?

Hi, this sensor would be very usefull to us. Does a channel like this already exist in your product at this date?

Import-PSSession : No command proxies have been created, because all of the requested remote commands would shadow exis
ting local commands.  Use the AllowClobber parameter if you want to shadow existing local commands.

Due to the very few requests, there are no changes to this. We will leave this open though, in case further requests come in.

Hello.

Thanks for the custom sensor, atm we are using it alot, but I wonder does anyone have an idea of how to get the same information from the Exchange 2007, its a bit tiring to be looking through event log every few days.

Hello,

This feature is still on our wish list, but I am afraid that there are no plans to implement it in the near future, sorry.

Best regards
