[Check_mk (english)] How to stop Check_mk truncating output from local checks (text wrapping)

Hi,

I’ve got a powershell script that I’m messing with to output the status of SQL jobs. Its all working fine except due to the length of the service name its truncating the returned data. If I inventory I see:

local SQLJOB-DeleteMaintContracts SQLJOB-DeleteMaintContracts OK - Succeeded 03/23/2014 20:00:00

local SQLJOB-Deletenotrequiredjobs SQLJOB-Deletenotrequiredjobs OK - Succeeded 03/23/2014 03:00:00

local SQLJOB-GeneralMaintenance.BackupCleanupFiles SQLJOB-GeneralMaintenance.BackupCleanupFiles OK - Succeeded 03/23/2014 04:0

local SQLJOB-GeneralMaintenance.BackupSystemDatabases SQLJOB-GeneralMaintenance.BackupSystemDatabases OK - Succeeded 03/23/2014 1

local SQLJOB-GeneralMaintenance.BackupTransactionLogs SQLJOB-GeneralMaintenance.BackupTransactionLogs OK - Succeeded 03/23/2014 2

local SQLJOB-GeneralMaintenance.BackupUserDatabase SQLJOB-GeneralMaintenance.BackupUserDatabase OK - Succeeded 03/23/2014 11:3

If you look at the end the time is being trunctated this appears to be where the text has gone passed a certain length. Any ideas how to allow more characters to be passed back ? If I run the test locally using “test” I can see the text
has cut off where its wrapped onto another line

OUTPUT from TEST

Any thoughts on how to stop this behaviour would be very appreciated ?

I’m using 1.2.4

Many thanks

Thanks Jim for the reply. It pointed me in the right direction.

What threw me was that when I tested in the interactive powershell console on the server it wasn’t wrapping the same so I initially ruled it out. It turns out though the interactive console has a different wrap
point than the one called from check_mk.

I had to make a couple of changes to my script to make it force a longer line. I had to

Add the following to the top of my script
$host.UI.RawUI.BufferSize = new-object System.Management.Automation.Host.Size(512,150);

Change my write line to
cmd.exe /c “echo $Crit SQLJOB-$jobname - Critical - The last run $jobLastRunOutcome @ $jobLastRunText” | Write-Output

The second bit may not be needed but it works on my rough test.

So, solved, using these lines in the scripts and we’re all good.

Just as an additional; whilst researching word wrap other articles suggested this improves in PS3.

Thanks for your help

Regards

Dave

One addition from my side.
You can also define the size of the console windows inside ps1 script. For the win_printers.ps1 plugin i submitted a patch (it is already included in git) that defines

the size inside the script.

## [http://blogs.technet.com/b/heyscriptingguy/archive/2006/12/04/how-can-i-expand-the-width-of-the-windows-powershell-console.aspx](http://blogs.technet.com/b/heyscriptingguy/archive/2006/12/04/how-can-i-expand-the-width-of-the-windows-powershell-console.aspx)

$pshost = get-host
$pswindow = $pshost.ui.rawui
$newsize = $pswindow.buffersize
$newsize.height = 300
$newsize.width = 150 (as big as you want)
$pswindow.buffersize = $newsize

Thats all what you need to add to the head of your script.

Is powershell adding a newline in the output? If so, that’s your problem since local data is only allowed

one one per service. I’m not that familiar with powershell so I don’t know how to tell it to not wrap lines.
