Correct, the secondary can act as an independent collector and logs can be forwarded directly to the M-100 from 5.0 FWs via the Collector Group > Log Forwarding configuration. Correct, either M-100 (primary or secondary) can be used to run reports or view logs which will be correlated across both Panorama HA pairs. To make this work you will need to configure the primary and secondary M-100 as Managed Collectors on the active box so that the config has both M-100s referenced. This will sync to both devices on Panorama commit and then you can add the secondary collector to a new independent log collector group, do a Panorama commit, and then a Collector Group commit. This should result in the configuration you desire. Note: You will also need to configure the Log Forwarding tab inside the Collector Groups to setup which FWs you want forwarding to the primary vs. secondary M-100.
