Inquiries about connecting to PRTG SNMP



Hello, we are conducting a POC in Korea with a free PRTG version.

We are an MSP company that uses AWS and KT Cloud in Korea as major CSPs.

We know that while using PRTG, it is very well connected for AWS, KT cloud requires SNMP to be connected and monitored.

I am inquiring because there was an error connecting SNMP to KT Cloud. The test server is a typical CentOS 7.X server, and PRTG is attempting to connect by installing an application on my local PC.

What is the solution to this error? ' SNMPERR_BAD_ASN1_BUILD(SNMP error # -11) ' .

Additionally, please let us know if there is any way to link SNMP to a private cloud (including the settings that the target server should do).

Thank you. I think your monitoring solution is very good.

Hi Lee,

First and foremost, thanks for considering PRTG as your monitoring solution.

1. In regards to the error you are facing while monitoring the test server in the KT cloud, have you tried to use the snmpwalk in the server to walk it locally? I think that's the best way to check if the SNMP component is properly configured in your server. Feel free to have a look at these links:

2. In regards to your second question, do you mean you want to monitor a server in a private cloud? PRTG needs to have access to port 161 to the private IP Address. If the condition is fulfilled, you should be able to monitor it. Otherwise, you may consider deploying a remote probe in the private cloud.

For more information relate to remote probe, please check here: https://www.paessler.com/manuals/prtg/remote_probes_and_multiple_probes

Please let me know if you have further questions on this topic.

With kind regards,
