How can we create a custom monitoring %cpu /%physical memory used/%logical disk used

Question

Anywhere we can find guide to create a custom monitoring %cpu+queuelength /%physical memory used/%logical disk used

Answer 1

Hi,

As far as I know, this feature is not of out-of-box monitor. To achieve this, we may create a script-based monitor, which requires some scripting skills .The script gets the current value, which may vary based on the different requirements.

If we don't already have the "Sample Management Pack", which is used for creating PowerShell script in SCOM, go ahead and download and install that first. It can be fetched from here: https://gallery.technet.microsoft.com/Sample-Management-Pack-17b76379

The following example shows how to generate an alert if a result*.csv file exists

First, create a monitor in operations manager, and save it in unsealed MP

name it and select the target
scom_ps_script_based_monitor_02.PNG

enter the script (if Linux computer, just provide the script path that already created in Linux)
scom_ps_script_based_monitor_03.PNG

configure the criteria (compare the current value with the threshold)
scom_ps_script_based_monitor_04.PNG

map health status

enable alerting and write the alert description if necessary

Hope the above information helps.

Answer 2

we need create extra or duplicate monitoring for %logical disk, %cpu+queue length & %physical memory used. how and where we can find the guide

Answer 3

Hi,

Sorry for missing the reply. For such customization issue, I'm afraid there is no existing guide to cover every detailed steps. In general, we may need to import the MP mentioned above, write the PS script (to achieve our goal) each, configure the criteria, setup the alert.

For example, for %logical disk, we may use the following script.

$pc = "mycomputer"  
  
$disks = get-wmiobject -class "Win32_LogicalDisk" -namespace "root\CIMV2" -computername $pc  
  
$results = foreach ($disk in $disks)  
{  
    if ($disk.Size -gt 0)  
    {  
        $size = [math]::round($disk.Size/1GB, 0)  
        $free = [math]::round($disk.FreeSpace/1GB, 0)  
        [PSCustomObject]@{  
            Drive = $disk.Name  
            Name = $disk.VolumeName  
            "Total Disk Size" = $size  
            "Free Disk Size" = "{0:N0} ({1:P0})" -f $free, ($free/$size)  
        }  
    }  
}  
# Sample outputs  
$results | Out-GridView  
$results | Format-Table -AutoSize  
$results | Export-Csv -Path .\disks.csv -NoTypeInformation -Encoding ASCII  

Here's the testing screenshots for your reference.

Hope the above information helps.
