SNMP Discovery error "Adding target to blacklist. No valid credential found for types [SSH Password,SSH Private Key]"

[Glenn11]

Hi MVP's,

Just wanted to guidance on the error i am getting "Adding target to blacklist. No valid credential found for types [SSH Password,SSH Private Key]".

Basically i am trying to discovery Network devices and it was alright. but it's just an eye sore seeing that error message everytime i am discovering network devices. Is there any way i can prevent that error pop's up?

Any suggestions?

Hey Glenn,

I guess you're relying on SNMP for discovering network devices rather than SSH? Best Practice would be to change the probe priority order so SNMP is tried earlier and avoids the error being logged.

The error is coming because SSH port is opened in your SNMP device and Discovery tries to authenticate using SSH credentials.

If you see the error message as irritating, You can create schedule specific to your SNMP devices and setup an SNMP behavior for your schedule.

If you enable IP Service Affinities, it will remember which service was used to discover each device and try that one first in the future.
