Is there a method to ensure something DOESN'T exist?

Votes:

0

We have a few servers where people who have admin rights did things like adding SMTP in the past. We do not want this. We can set up SNMP checks to see if a service is present, or a port check to ensure that something is up. But is there a way to do the opposite, and have it be "positive"?

Check if service is not installed or running

To check if a service is not installed or not running, you can use the ServiceStatus sensor from http://prtgtoolsfamily.com/downloads/sensors.

It will return the status of a service where

0=NotInstalled
1=Stopped
2=StartPending
3=StopPending
4=Running
5=ContinuePending
6=PausedPending
7=Paused

Using channel limits, you can set the sensor to the Down status if the service is installed or running.
