Auto Discover of AWS Servers

Votes:

0

I am currently using auto discover to pull new servers from AWS into our PRTG. This is also adding devices that are not servers that only have an IP address and only get a Ping sensor. I'm not sure what these devices are. They seem to come and go. I can search my instances and they do not show up.

Is there a way of filtering out the devices that don't have DNS names, or maybe deleting them after the discovery is completed. I'm not sure how I would search for devices that only have an IP for a name to remove them from PRTG.

Hi Philip,

The Auto Discovery has multiple option how you can address a range of devices. If you don't want to have device which cannot be translated to a DNS name, I recommend to use a list of DNS as target group. Another alternative would also to use the OU from your domain if the target devices are part of one.

I opened a ticket with AWS and we figured out that network interfaces has its own section within AWS. Things like databases, load balancers, lambdas, etc use network interfaces even though they are not using a legacy server and they can grab an IP address when required and release them again. Something to be aware of when scanning a subnet in AWS.

Would anyone have a script using the API to remove a device if all it has is an IP address and a ping sensor?

Hi Philip,

Thank you for the feedback.

We have no certain script for this, but I recommend to use the following third party API: https://github.com/lordmilko/PrtgAPI

This API has more options as the native one and should provide all required commands.
