In Veeam ONE, if you have been logged out, you can get back to where we downloaded the package by clicking the Settings Cog in the top right
Click Data Collection/Overview/Data Source/Add Server
Click Veeam Backup And Replication
If you have VEM, enter the FQDN and select the server type as Enterprise Manager, if you dont have this, enter the VBR FQDN, for standalone VBR, if you have a HA cluster, use the cluster FQDN
In my case, I am using the VEM FQDN, which has my VBR HA cluster added
When you are happy click Next
Click Add Credentials
Click ok here
Select Standard Account and click Next
Enter the veeamadmin credentials and a description, then click Finish
Click Next
For the certificate, click Trust And Continue
there may be a few of these
When thats done, click Finish
Give VeeamONE plenty of time, as we manually installed the agents, we may see duplicated entries in the Data Collection menu, it will sort them out
When its done it should look like this, the secondary node will be unhealthy as only the active node will be sending metrics
If you fail over it will look like this, I had a ghost entry for the secondary server that wouldnt disappear, but it isnt an issue, the primary is unhealthy as its now not sending metrics, which is expected
