Monitor SMTP Virtual Server

Hello,

We have an SMTP Virtual Server setup in IIS 6.0 Manager running on our Windows server that acts as our email relay to our hosted Exchange for printers and other scan to email devices.

I have tried the sensor Windows IIS 6.0 SMTP Sent to monitor, but it has failed in adding. My purpose is to be notified if the service stops. Is this the correct sensor? If so how do I set it up, if not what sensor should I be using?

Thanks, Tim

Hi there,

Please use the "WMI Service" sensor instead to monitor the current state of the SMTP-Service.

Best regards.

Hello,

That only seems to monitor the SMTP service. I am successfully monitoring that service already. What I would like to monitor is if the SMTP Virtual Server state (start/stop) in IIS 6.0. If I manually stop the SMTP Virtual Server in IIS 6.0, the SMTP Service continues to run thus not alerting me if the SMTP Virtual Server has stopped.

Thanks, Tim

Hi Cosmos,

The best approach probably is to make sure SMTP is available on e.g. port 25. The SMTP sensor (default PRTG) might be more sufficient for this.

Another good idea would be to monitor the directories on the IIS itself.

A word of advice out of personal experience with the IIS SMTP engine - it is not actually very powerful nor robust - it has its quirks. If you want something cheap, actually free, look at this alternative service for SMTP that gives you a lot more options, works more stable and is easier to administrate as well: https://www.hmailserver.com/

It is a pretty famous SMTP open source project that really does a good job - have used it a lot for internal SMTP relay servers with great success and eliminating a lot of the issues and challenges with IIS. I monitor the h-mail service, the SMTP port/connection and the SMTP queue directory for to many files and to old files (e.g. 1 hour and above) to see if anything got stuck and or stressing the system.
