PRTG Custom Sensor to monitor NoSpamProxy Message Flow

Description

This script helps you to monitor message flow in a NoSpamProxy environment using a PRTG custom PowerShell sensor.

This custom sensor contains the following five channels:

• In/Out Success
  Total of inbound/outbound successfully delivered messages over the last X minutes.
• Inbound Success
  The number of inbound successfully delivered messages over the last X minutes.
• Outbound Success
  The number of outbound successfully delivered messages over the last X minutes.
• Inbound PermanentlyBlocked
  The number of inbound blocked messages over the last X minutes.
• Outbound DeliveryPending
  Number of outbound messages with pending delivery over the last X minutes

The default interval is five minutes. But you might want to change the interval as needed for your environment.

These channels can easily be modified, and additional channels can also be added.

NoSpamProxy is a powerful anti-spam gateway solution providing additional functionality like centralized S/MIME and PGP encryption for on-premises and Exchange Online deployments.

PRTG is an industry-standard system monitoring solution.

Examples

The script takes no additional attributes and is called by the PRTG probe.

To verify your setup, you quickly execute the PowerShell script. It returns an XML result.

PS C:\Scripts> .\Get-NoSpamProxyPrtgData.ps1      
In/Out Success    0    Count        
Inbound Success    0    Count        
Outbound Success    0    Count        
Inbound PermanentlyBlocked    0    Count        
Inbound DeliveryPending    0    Count    
10    1  

The PRTG channel configuration

The following screenshot shows PRTG example graphs.

Notes

The custom PowerShell script must be saved to the following location of the PRTG probe:

[INSTALLPATH]\PRTG Network Monitor\Custom Sensors\EXEXML

Ensure to have the PowerShell execution policy is set correctly. Otherwise, the PRTG service won’t be able to execute the PowerShell script.

Ensure that the service account used by the PRTG probe has access to the script and is a member of the NoSpamProxy Monitoring Administrators security group.
