Replacing vROPS Certificates
Issue: When using default certificates in vROPS Due to security requirements it was necessary to replace the default self-signed certificates with a trusted certificate signed by an internal CA. Unlike vCenter, vROPS uses a common name vc-ops-slice-1 followed by slice-2 for data and other node, where vCenter has SAN names in the default certificate so when you add the root of the local machine trusted store then the vCenter url shows secured. In order to make the secure SSL we have to generate the CSR and get it signed by any third party SSL vendors or our own Microsoft CA. I will be generating a CSR and getting signed by internal Microsoft CA .We can refer this below article from VMware as reference. https://kb.vmware.com/s/article/2046591?lang=en_us Steps: 1.The first step is to create a new private key from taking a SSH session to master node vROPS. openssl genrsa -out vrops.key 2048 2. Using the configuration file below make sure to provide de...

Using Custom Certificates in Usage Meter 4.x As we get to move on with customers and service providers asking to implement to use a secure web browser access to Usage Meter .The old versions of UM has methods to replace the certificates.
