vSAN Health PRTG Sensor | Pigeon Nuggets

I just wanted to create a quick post on a PRTG Network Monitoring Sensor that I created to provide some monitoring for vSAN deployed in my Lab. The script is not extensively tested as I am just using it in the Lab however hopefully you will get some value from it. The sensor performs an Invoke of a vSAN Health check against a VSAN cluster and reports any failures or warnings for components.

The sensor is available from my Github and uses a module from Roman Gelman (@rgelman75) VSAN.psm1 which is available from here.

Sensor Setup

Download PRTG-vSphere-vSANealth.ps1 from here and place it in C:\Program Files (x86)\PRTG Network Monitor\Custom Sensors\EXEXML\ on your Probe
Download the prtg.customlookups.vsan.status.ovl from here (Custom Lookup for PRTG) and place this file in C:\Program Files (x86)\PRTG Network Monitor\lookups\custom\ on your Central Probe
Download VSAN.psm1 from here and place this in C:\Program Files (x86)\PRTG Network Monitor\Custom Sensors\EXEXML\ on your Probe
Logon to PRTG and select Setup > Administrative Tools > Load Lookup and File Lists

5. Next against your vCenter device create a new Sensor of type EXE/Script Advanced

6. Enter the following parameters and then click Continue to finish the setup:

Sensor Name: The name of the sensor (e.g. VSAN Cluster Status – Development)
EXE/Script: PRTG-vSphere-vSANHealth.ps1
Parameters: -vCenterServer “<FQDN of your vCenter>” -vSANCluster “<Name of the VSAN Cluster>”
Security Context: Use Windows Credentials of parent device
Timeout (Sec): 300

After configuration it should start reporting the status and you can setup notifications, monitoring frequency and channel limits as desired.

Troubleshooting

The User executing the scripts (the Windows account specified in PRTG) must have sufficient rights to the vCenter Server
PRTG runs all PowerShell scripts under the 32-bit image; this will cause PowerCLI not to run unless the modules are installed under the x86 Modules folder. The easiest way to fix this is to run: Save-Module -Name VMware.PowerCLI -Path SystemRoot%\SysWOW64\WindowsPowerShell\v1.0\Modules\
If you encounter a number of virtual machines in your enviornment “vsan-healthcheck-disposable….” in your environment this is due to the Timeout value (which is statically set to 2 seconds) not being high enough in the VSAN.psm1 module; find any references to VsanQueryVcClusterHealthSummary and replace the Integer 2 with something higher (eg. 30 seconds)

    .SYNOPSIS
    Returns a channel in XML format for a PRTG Sensor

    .DESCRIPTION
    Creates a channel for a PRTG Advanced XML/EXE sensor with the custom data provided.

    .PARAMETER Name
    The name of the channel

    .PARAMETER Value
    The Interger Value of the channel

    .PARAMETER ValueLookup
    A valid PRTG Lookup Type eg. oid.paessler.custom.windows.scheduledTaskStatus

    .PARAMETER LimitErrorMsg
    The error message to display when the channel exceeds the defined error limits. WARNING: This can not be set dynamically; the first set value is retained in PRTG

    .PARAMETER LimitWarningMsg
    The warning message to display when the channel exceeds the defined warning limits. WARNING: This can not be set dynamically; the first set value is retained in PRTG

    .PARAMETER LimitMaxError
    If the "Value" is higher then the "LimitMaxError" the channel will be marked as in an Error state and the defined LimitErrorMsg will be displayed for this sensor. The parent sensor will also go into an error state.

    NOTE: This value is not dynamic; if this value is provided the first value that PRTG recieves when the channel is created is the value that will persist forever. Generally it is recommended that instead of using these parameters that the channel settings are manually set.

    .PARAMETER LimitMinError
    If the "Value" is lower then the "LimitMinError" the channel will be marked as in an Error state and the defined LimitErrorMsg will be displayed for this sensor. The parent sensor will also go into an error state.

    NOTE: This value is not dynamic; if this value is provided the first value that PRTG recieves when the channel is created is the value that will persist forever. Generally it is recommended that instead of using these parameters that the channel settings are manually set.

    .PARAMETER LimitMaxWarn
    If the "Value" is higher then the "LimitMaxWarn" the channel will be marked as in an Warning state and the defined LimitWarningMsg will be displayed for this sensor. The parent sensor will also go into an Warning state.

    NOTE: This value is not dynamic; if this value is provided the first value that PRTG recieves when the channel is created is the value that will persist forever. Generally it is recommended that instead of using these parameters that the channel settings are manually set.

    .PARAMETER LimitMinWarn
    If the "Value" is lower then the "LimitMinWarn" the channel will be marked as in an Warning state and the defined LimitWarningMsg will be displayed for this sensor. The parent sensor will also go into an Warning state.

    NOTE: This value is not dynamic; if this value is provided the first value that PRTG recieves when the channel is created is the value that will persist forever. Generally it is recommended that instead of using these parameters that the channel settings are manually set.

    .EXAMPLE
    New-PRTGChannel -Name "Disk Status" -Value 20 -ValueLookup "oid.paessler.custom.hardware.diskstatus"

    Returns a PRTG Channel named "Disk Status" with a custom lookup type of "oid.paessler.custom.hardware.diskstatus" and a value of 20.

   .EXAMPLE
    New-PRTGChannel -Name "Disk Status" -Value 20 -ValueLookup "oid.paessler.custom.hardware.diskstatus" -LimitErrorMsg "The disk status is bad." -LimitWarningMsg "The disk status is getting bad." -LimitMaxError 25 -LimitMinError -1 -LimitMaxWarn 21 -LimitMinWarn 0

    Returns a PRTG Channel named "Disk Status" with a custom lookup type of "oid.paessler.custom.hardware.diskstatus" and a value of 20. The channel also has the channel Warning/Error limits set. These will be addative with the limits defined in the Custom Lookup. It is not recommended that these are defined unless required; the Error/Warning state can be controlled using the Custom Lookup type metadata.

    .EXAMPLE
    New-PRTGChannel -Name "Disk Status" -Value 10
    Returns a PRTG Channel named "Disk Status" with a value of 20.

    .EXAMPLE
    New-PRTGChannel -Name "Disk Status" -Value 10
    Returns a PRTG Channel named "Disk Status" with a value of 20.

.SYNOPSIS

Returns a channel in XML format for a PRTG Sensor

.DESCRIPTION

Creates a channel for a PRTG Advanced XML/EXE sensor with the custom data provided.

.PARAMETER Name

The name of the channel

.PARAMETER Value

The Interger Value of the channel

.PARAMETER ValueLookup

A valid PRTG Lookup Type eg. oid.paessler.custom.windows.scheduledTaskStatus

.PARAMETER LimitErrorMsg

The error message to display when the channel exceeds the defined error limits. WARNING: This can not be set dynamically; the first set value is retained in PRTG

.PARAMETER LimitWarningMsg

The warning message to display when the channel exceeds the defined warning limits. WARNING: This can not be set dynamically; the first set value is retained in PRTG

.PARAMETER LimitMaxError

If the "Value" is higher then the "LimitMaxError" the channel will be marked as in an Error state and the defined LimitErrorMsg will be displayed for this sensor. The parent sensor will also go into an error state.

NOTE: This value is not dynamic; if this value is provided the first value that PRTG recieves when the channel is created is the value that will persist forever. Generally it is recommended that instead of using these parameters that the channel settings are manually set.

.PARAMETER LimitMinError

If the "Value" is lower then the "LimitMinError" the channel will be marked as in an Error state and the defined LimitErrorMsg will be displayed for this sensor. The parent sensor will also go into an error state.

.PARAMETER LimitMaxWarn

If the "Value" is higher then the "LimitMaxWarn" the channel will be marked as in an Warning state and the defined LimitWarningMsg will be displayed for this sensor. The parent sensor will also go into an Warning state.

.PARAMETER LimitMinWarn

If the "Value" is lower then the "LimitMinWarn" the channel will be marked as in an Warning state and the defined LimitWarningMsg will be displayed for this sensor. The parent sensor will also go into an Warning state.

.EXAMPLE

New-PRTGChannel -Name "Disk Status" -Value 20 -ValueLookup "oid.paessler.custom.hardware.diskstatus"

Returns a PRTG Channel named "Disk Status" with a custom lookup type of "oid.paessler.custom.hardware.diskstatus" and a value of 20.

.EXAMPLE

New-PRTGChannel -Name "Disk Status" -Value 20 -ValueLookup "oid.paessler.custom.hardware.diskstatus" -LimitErrorMsg "The disk status is bad." -LimitWarningMsg "The disk status is getting bad." -LimitMaxError 25 -LimitMinError -1 -LimitMaxWarn 21 -LimitMinWarn 0

Returns a PRTG Channel named "Disk Status" with a custom lookup type of "oid.paessler.custom.hardware.diskstatus" and a value of 20. The channel also has the channel Warning/Error limits set. These will be addative with the limits defined in the Custom Lookup. It is not recommended that these are defined unless required; the Error/Warning state can be controlled using the Custom Lookup type metadata.

.EXAMPLE

New-PRTGChannel -Name "Disk Status" -Value 10

Returns a PRTG Channel named "Disk Status" with a value of 20.

.EXAMPLE

New-PRTGChannel -Name "Disk Status" -Value 10

Returns a PRTG Channel named "Disk Status" with a value of 20.
