Configure SSL/TLS for Nagios Log Server

I am configuring SSL for our Nagios Log Server instances.
I was able to configure on one instance of NLS successfully using
https://assets.nagios.com/downloads/nag ... Server.pdf.
My question, how does this work on a NLS instance which is clustered with 2 or more instances of NLS?
Thank You,
Sampath

If you log into the web UI on multiple of the machines in the cluster you would want o do the same on each machine.
If you only view the web UI from one machine this isn't necessary.

We don't login to UI of either of the machines. We have a DNS Entry (CNAME) created "logserver.company.com" which points to one of the 2 servers in cluster.

then you would want to copy the certificate to both machines and update the config on both machines

You mean configure SSL on both servers separately?
Since we use a CNAME to access NLS, I should be mentioning the CNAME when Certificate is Signed?

Yes, you would set them up both exactly the same using the same certificate.

Yes. The CNAME is the hostname or Common Name. You will see this on page 3 of the document
