In a vCloud Foundation environment, running Aria Operations for Logs, there is an integration configured with vSphere using the vSphere administrator account.
If reconfiguring the integration to authenticate using a service account, the credentials revert to the local vSphere administrator account used initially.
Aria Operations for Logs 8.x
VCF 5.2.1
Whenever SDDC rotates the local vSphere administrator password, the workflow updates the credentials for the Operations for Logs to vSphere integration for that specific vSphere.
This results in the service account credentials being overwritten.
Currently, there is no resolution to this issue.
It is possible the workflow will be changed in an upcoming release.
