Hello! I'm copy/write powershell xml script for monitoring Exchange DB Status.

$servername = "servermbx" 


$pssession = new-pssession -configurationname "Microsoft.Exchange" -connectionuri "http://$servername/Powershell" -Authentication Kerberos 
$startsession = import-pssession -session $pssession -allowclobber -WarningAction SilentlyContinue | out-null 

$dbstatus = get-mailboxdatabasecopystatus | select name,ActiveCopy
$dbcount = (Get-MailboxDatabaseCopyStatus).count 

$prtg = '<?xml version="1.0" encoding="Windows-1252" ?> 
<prtg>'
 
foreach ($db in $dbstatus) 
{ 
  $dbname = $db.Name 
  $dbstate = $db.ActiveCopy 
  $dbvalue = "10" 
  if ($dbstate -match "False") 
  { 
    $dbvalue = "1" 
   } 
    if ($dbstate -match "Active") 
   { 
    $dbvalue = "2" 
   } 
     
  
$prtg +="
    <result> 
        <channel>$dbname</channel> 
        <value>$dbvalue</value> 
        <showChart>1</showChart> 
        <showTable>1</showTable> 
        <mode>Absolute</mode>
    </result> 
" 
} 

$prtg +="<text>The number of databases: $dbcount</text> 
</prtg>" 
remove-pssession -session $pssession 
$prtg 

How i can edit this script or this:

When state of database False - sensor OK, state of database - Active - Sensor Error.

Now, in both cases state False or Active PRTG monitor say what sensor is Ok.

Dear dukedizel

There are two options to set a sensor to an error status

  • Return the according XML result using the node <Error>
  • Return another value channel and use the channel limit to change the sensor state

The latter approach allows to also return monitoring values, even though the sensor is in the alarm state.

Dear dukedizel

An example output is

   <prtg>
   <error>1</error>
   <text>Your error message</text>
   </prtg>

Please find the full documentation in the API manual which is integrated into the PRTG webinterface: Setup | PRTG API, tab "Custom Sensors".

My sensor: <?xml version="1.0" encoding="Windows-1252" ?> <prtg> <result> <channel>Moscow VIP Users\SRVMBX250</channel> <value>2</value> <showChart>1</showChart> <showTable>1</showTable> <mode>Absolute</mode> <error>2</error> <text>Your error message</text> </result> <text>The number of databases: 3</text> </prtg>

limits do not work ... I create a new sensor but the sensor configured channel limits are not settable.

what am I doing wrong?

Dear dukedizel

If you open the sensor channel configuration by clicking on its gauge, you should be able to enable and set the limits. Please clarify in which sense the limits are not settable.

I form this: <?xml version="1.0" encoding="Windows-1252" ?> <prtg> <result> <channel>Moscow VIP Users\SRVMBX250</channel> <value>2</value> <showChart>1</showChart> <showTable>1</showTable> <mode>Absolute</mode> <error>2</error> <text>Your error message</text> </result> <text>The number of databases: 3</text> </prtg>

I see this sensor in PRTG but Limits not settable automatically. Parameters <error>2</error> are not taken from the file. I have to put limits manually.

The error limits must be defined in the XML output and are only read when the sensor created (i.e. they can't be changed after created). The following XML values have to be present:

<limitmode>1</limitode> <!-- mandatory !-->
<LimitMinError>10</LimitMinError>
<LimitMaxError>10</LimitMaxError>
<LimitMinWarning>10</LimitMinWarning>
<LimitMaxWarning>10</LimitMaxWarning>
<LimitErrorMsg>Your error message</LimitErrorMsg>
<LimitWarningMsg>Your Warning message</LimitWarningMsg>

Set the Limit tags according to your needs :) Further information can be found on
