Environment

Aria Operations for Networks 6.13.0
Aria Operations for Networks 6.14.0
Aria Operations for Networks 6.14.1

Cause

Invalid credentials error is expected error seen as the user used is SNMP Read Only User to validate.
For datasource validation and adding Datasource a Read Only SSH user is needed with Network Operator Role. 

Resolution

1. For datasource validation and adding Datasource a Read Only SSH user is needed with Network Operator Role. 
2. Once the datasource is added then read only SNMP user is used for SNMP configuration.
3. Work with your Network administrator on the below mentioned 2 users and permissions, both are needed:
   
   a) Read-only user: VMware Aria Operations for Networks  requires read-only third-party device credentials (passwords) to access the SSH data. This user needs to have the Network Operator role. 
   b) Read-only SNMP user: VMware Aria Operations for Networks uses SNMP to collect metrics information from third-party devices (switches, routers, firewalls, and so on).
