Have upgraded a few 100 FWs (UF & HF) to Splunk 8.2.3. Looking for a bench marking checks to make sure they are fully functional. We have a large clustered (Indexers / SHs), with ES. Any SPLs for bench marking instances upgraded, on ES & FWs are appreciated. Thank u & stay safe.
This is likely to be site-specific so there aren't any ready-made solutions. However, between the Missing Forwarders feature in the MC and the TrackMe app you should get close to what you seek.
