Below URL shows how to integrate VRLI with VROPS.
But I have few questions related to this.
1. Does all the event & log data get forwarded to VRLi from VROPS and vice versa
2. If yes, can we send all the log and event data from VRLi to splunk through data input option in splunk
You have the option to choose which logs you wish to forward from vROPS on the Log Forwarding page: Log Forwarding
Secondly, I believe you can still forward event data from vRLI to splunk. Please refer: https://blogs.vmware.com/services-education-insights/2018/02/configuring-vrealize-log-insight-event-...
So as mentioned in my previous reply, you will need to configure Log Forwarding in vROPS to vRLI: Log Forwarding after initial configuration: Configuring vRealize Log Insight with vRealize Operations Manager
I think this article should help you: vROps self monitoring with vROps and Log Insight – Rick Verstegen // BLOG
