Duplicate device detection or scan

Good day

I have a PRTG installation that is working very well.

Over time different persons have managed different sections of the architecture on site. What I have found now is that some devices have been added to the system twice. Is there a way to scan for or find what devices have been added to my installation more than once.

Doing this per IP would be the most beneficial in my opinion.

Currently I am finding these devices by accident when I notice the device in more than one place.

If there is already a solution posted please point me to this as I have not been able to find a descriptive solution in the knowledge base.

Thank you for your assistance regarding this.

Hello Etienne,

There is no built-in function to identify duplicate hosts retrospectively, but you can use this API call as a starting point: http(s)://your.prtg.server/api/table.xml?content=devices&output=xml&columns=objid,probe,group,device,host,baselink

This will give you an XML file you can open in Excel, containing all devices and their IP or hostname as configured in PRTG. This way you can at least identify easily redundant IPs and hostnames. What it does not do since Excel has no formula to do this out of the box is to lookup which hostname would match which IP.

One more thing: The API call is limited to deliver max. 500 items, so in case you have 600 devices for example, add a count parameter to the API call like this: http(s)://your.prtg.server/api/table.xml?content=devices&output=xml&columns=objid,probe,group,device,host,baselink&count=600

Kind regards.

Thank you for this info. It gave me everything I needed to find the duplicates. I do not mind removing them manually now that I have the ability to find them.
